The increasing impacts of the drought, in tandem with social tensions and economic losses, have exposed South Africa’s challenges at a level that can’t accommodate half-measured responses.

MIESA’S COMMITMENT to the public infrastructure sector in 2016 is centred in its principle purpose of advancing the profession of municipal engineering in South Africa. For over 30 years, as the official publication of the Institute of Municipal Engineering of Southern Africa, the value the magazine’s readership has contributed to South Africa’s development remains unequalled by any other sector. Today, IMIESA is read by engineering and other professionals across all three tiers of government, state-owned enterprises and agencies involved in infrastructure deliver y. The sector is more complex than ever before, but the goal remains the desired decentralised model of ser vice deliver y at a functional municipal level.

National Water Week South Africa’s drought continues unabated, and the extent and range of its impacts are both growing at a pace that may soon exceed our capacity to prevent the disaster becoming one of humanitarian proportions. Water scarcity is South Africa’s most profound natural challenge, and the countr y boasts numerous groundbreaking feats of engineering that continue to deliver highly sustainable results, most notably the water transfer schemes, without which Johannesburg couldn’t sur vive. However, equally profound historic challenges have left the nation severely ill-equipped to handle the drought upon us.

This edition of IMIESA keeps its traditional focus on South Africa’s National Water Week, but the severity of the emerging national crisis demands suppor t. This issue aims to practically resource and equip all public sector engineers, especially municipal engineers, and the technical staff supporting them, with access to the most current, effective and available solutions to the challenges faced right now, with particular focus on those with the potential to integrate with longer-term infrastructure strategies.

A call to action With the areas of the Western Cape joining KwaZulu-Natal, Mpumalanga, Limpopo, the Free State and North West declared disaster zones, South Africans across the spectrum are responding. The continuing stream of water and transport being donated from South Africans to suffering regions nationwide is a practical demonstration of the health of our national unity. Government is finding ways to ensure relief effor ts keep up with increasing needs, and is trucking water to the worstaffected provinces, including KwaZuluNatal and the North West, as well as refurbishing boreholes and speeding up relief responses for rural farmers. Inadequate preparation is a chief cause for concern, but South Africa has the needed skills to overcome this – from both a technical and disaster management point of view.

The Municipal Benchmarking Initiative: benchmarking our way to better services, more effectively and efficiently Duncan Daries, IMESA president

The relaunched Salga/WRC Municipal Benchmarking Initiative (MBI) has been assisting municipalities with per formance measurement and improvement since 2011, with the establishment of a suppor t network of peers and dedicated professionals where municipalities can share common experiences, achievements and challenges in a manner that enables improved per formance.

HE MBI EFFORT and the associated progress have been substantial; yet, this is still ver y much a fledgling process, with reference to Figure 1, in which the majority of municipalities are in Stage 1 (bearing in mind that international experience among competitive private sector multinational institutions is that each stage has a duration of some four years). With time and commitment, the MBI can lead

to substantial breakthrough improvements in water ser vices deliver y in South Africa. The new National MBI Repor t will be launched at a prestigious event at Emperors Palace, Kempton Park, on 4 March 2016. In excess of 200 delegates are expected, including representatives from key water sector stakeholders such as local, district and metropolitan municipalities, water boards, Salga, the WRC, the Department of Water & Sanitation,

National Treasur y, the Depar tment of Cooperative Governance and Traditional Affairs, the Development Bank of Southern Africa, private companies, other government depar tments, donors, NGOs and universities. A lunch session will follow the event to allow for fur ther networking opportunities.

National Report highlights MBI team leader Grant Mackintosh has noted that the 2015 MBI National Report builds on the ver y positive response to the 2014 report; i.e. it has been structured to be easy to read, simple to understand and ver y informative. The main objectives of the report are to showcase achievements, and encourage and assist those who are not yet part of MBI to participate. Highlights of the MBI National Report include: (1) messages of support and encouragement by key project sponsors, (2) summar y of peerbased process benchmarking initiatives, (3) insights shared by MBI ambassadors and leading practitioners, and quotes from peer group interactions, (4) per formance indicators for each of the six MBI modules, (5) indication of key national challenges/priorities for each of the modules, (6) tips and hints to motivate participation and facilitate improved understanding, (7) insights provided by metros during cities working groups and other peer group interactions, (8) highlighting key

PRESIDENTâ€™S COMMENT

developments within the water sector, and (9) the Water Ser vices League. Munibench was pre-populated with data drawn from third par ties, and a draft MBI scorecard was generated for ever y water ser vices authority (all 152). These draft scorecards allowed municipalities the opportunity to view their per formance versus peers, and correct data issues (i.e. incorrect data, no data). The project team then checked/verified/finalised data submitted for publication in the national report. A total of 37 PIs were generated for the new National MBI Report.

New approaches The National MBI Report launch event will also include the signing of a benchmarking funding agreement between the Depar tment of Public Ser vice and Administration (DPSA) and Salga/WRC. The specific grant funding obtained is the Tirelo Bosha Public Ser vice Improvement Facility, which intends to contribute towards enhanced capacity for improved

public service delivery in South Africa. More specifically, it aims to support and pilot new ways of delivering public service through contributing to the improvement of frontline public service delivery by stimulating and supporting improvement initiatives at all levels. Importantly, the current focus of this facility is on the following two sub-themes: (1) Improving service delivery through the use of information and communication technologies, and (2) The back to basics approach. Considering this, the 18-month grant will focus on increased peer interactions and knowledge sharing, further enhancing Munibench, and ensuring MBI is aligned to and supports the back-to-basics programme to the benefit of municipalities. Much work is still required to ensure that municipalities are: monitoring/measuring their performance, reporting and assessing their own performance with a view to improve, and engaging other municipalities and sharing experiences, challenges, issues of concern (and, through this

process, improving their performance). In order to overcome identified challenges and still make significant progress, ongoing reinforcement of MBI principles to municipalities (especially via peer group activities) is, therefore, of primary importance.

Funding Although Salga and the WRC are continuing to provide financial support to the MBI, and the Tirelo Bosha (DPSA) grant funding will help maintain MBI momentum additional funding is required to further enhance the MBI programme. Starting with the new financial year of 2016/17, Salga and the WRC will facilitate municipalities to make a small contribution towards sustaining this excellent initiative. The success of the MBI is dependent on your interest, commitment and involvement. If you are not yet part of the MBI, I, and IMESA, encourage you to contact Salga, the WRC, IMESA or the MBI team and get involved. There is nothing to lose and much to gain! IMIESA March 2016

COVER STORY

Mastering the water cycle With a staff complement of over 2 000 committed people, including 300 engineers, water specialists and technicians, Water and Sanitation Services South Africa (WSSA) has a presence on more than 800 sites in all nine South African provinces, and across Southern Africa.

SSA HAS BEEN specialising in the upgrading, optimisation, operation and maintenance of water and effluent systems in Southern Africa – covering not only the municipal environment, but also the industrial sector – for over 30 years. The company’s experience extends from cities to rural areas and spans the full water cycle.

Facing water challenges head on A presence like this undoubtedly places this solutions provider on the frontline of some of the country’s most gruelling water challenges. The immediate challenge facing the water services sector in South Africa is the current drought, according to Sylvia Tshivhunge, director: Municipal Services, WSSA. “A number of water resources have dried up and communities have little or no water supply. In such instances, and in collaboration with the

relevant water services institutions (WSIs), WSSA can implement mechanisms aimed at minimising water losses throughout the water supply chain. “Using our extensive knowledge and experience in groundwater, we already assist with drilling new boreholes and rehabilitating nonoperational boreholes.” WSSA also provides water tanker management services to municipalities with extensive rural communities. “We can also provide desalination units, where appropriate, at relatively short notice,” adds Tshivhunge. Another challenge facing the sector is dilapidated infrastructure. The refurbishment, upgrade and expansion of water and wastewater infrastructure forms a part of most of WSSA’s operation and maintenance contracts. “We also provide these services though stand-alone contracts to various WSIs.”

Making a critical difference to water security The National Development Plan (NDP) 2030 states that WSIs must reduce their water losses to below 15%. Currently, the average water loss is above 40% – much higher than the NDP target – meaning that clean water that was supposed to reach communities is lost through the system. In order to curb these losses, WSSA can assist WSIs to develop water conservation/demand management (WCDM) strategies and BP, including water leak programmes. In a number of cases, effluent from wastewater treatment works doesn’t comply with set standards. This effluent tends to be discharged to water courses, affecting the quality of raw water. Treating polluted water is quite expensive and a financial burden that most WSIs can ill afford. WSSA has a long and proven track record in the management, operation and maintenance of water and wastewater plants. The company can also assist WSIs to draw up a proper monitoring programme, with sampling and analysis. Apart from handling wastewater pollution, WSSA has experience in operating acid mine drainage plants, which adds to its services, making a critical difference to security of supply.

clients, in order to maintain it. The company believes that its employees are valuable, so training and development are core to company strategy. “Training and the transfer of skills are central to what WSSA does and, in areas where the company operates, these elements normally form part of the key performance indicators, and rightfully so.”

ABOVE Clariflocculator at Middledrift Water Treatment Works RIGHT Sludge activated process at Zandvleit Wastewater Treatment Works

Changing priorities WSSA provides a number of support services to municipalities and utilities, with the most sought after of these being assistance with Blue/Green Drop standards, although WSIs have made some strides in this area. The support entails the development of documents, which include process audits, water safety plans, wastewater risk abatement plans, incident management protocols, monitoring programmes, water services by-laws, and the setting up of operational systems. However, this has changed since the Department of Water & Sanitation took a firmer stance against water losses and leaks. “With the introduction of the No Drop programme, development of WCDM strategies and BP has emerged as one of the most sought-after support services,” explains Tshivhunge. “In addition to that, sludge management is beginning to receive more attention,” she adds. Beyond servicing the changing support priorities of municipalities, WSSA also provides a number of operation and maintenance services. In most instances, services required by municipalities include: • annual condition grading assessment of the assets • maintenance plan and task scheduling • SHEQ plans • asset register as per Blue/Green Drop requirement • preventative maintenance • repair and refurbishments • plant operations, including staff management.

Partnering for solutions Par tnership typifies WSSA’s approach to dealing with challenges and finding solutions in consideration of their clients’ needs and desired outcomes. “WSSA believes that ever y problem has a solution and, in partnership with the client, we can overcome almost any obstacle. A recent incident in our Rustenburg plant is a fine example of this. “We had operational challenges that required cooperation between us and the client. One of the problems was the industrial effluent that was dumped at the works by private trucks. Some of the effluent contained chemicals that kill microorganisms necessary for effective wastewater treatment. In partnership with the client, we implemented a monitoring programme for the trucks,” explains Tshivhunge. “Furthermore, this effluent was diverted into a separate lagoon for stabilisation and pretreatment, before releasing to the mainstream treatment works,” she adds.

Certified services WSSA is one of the few water service providers in Southern Africa that has triple ISO certification, i.e. ISO 9001, ISO 14001, ISO 18001 – all integrated into one management system. In addition, WSSA enjoys CIDB ratings of 9CE, 9ME and 9EP. From this level of certification, it is clear that the company understands the value of credibility, which is why it constantly strives to grow the knowledge base of its employees and

The package of skills programmes ranges from process control and quality monitoring to effective plant maintenance. “Over time, the client’s employees are able to operate and maintain the plant with little or no assistance from WSSA.” As employees are developed, the company follows an internal retention strategy to ensure such skills are retained. WSSA also sends its employees to waterrelated conferences and encourages its technical staff to register with various professional bodies. “We have an absolute commitment to providing sustainable, quality water and sanitation ser vices to the communities we ser ve, in partnership with our clients. We further believe in the consistent application of best practices, people development and environmental care in all our operations,” concludes Tshivhunge.

AfDB to invest $50 billion in energy sector

The African Development Bank (AfDB) says it hopes to invest between $40 and $50 billion in the energy sector across the continent. According to AfDB president Akinwumi Adesina, the AfDB plans to invest $12 billion in the energy sector over the next five years. He said the bank would also triple its climate finance to Africa, to $5 billion per year by 2020, in order to support climate change adaptation and mitigation efforts on the continent. The AfDB chief said that while over 645 million Africans lacked access to electricity, 700 million did not have access to clean cooking gas. “Africa is simply tired of being in the dark. It is time to take decisive action and turn this narrative around: to light up and power Africa, accelerate the pace of economic transformation, unlock the potential of businesses, and drive much-needed industrialisation to create jobs.

Nairobi governor Evans Kidero says this shows commitment by City Hall towards effective service delivery to residents within the county. “Better transport, housing and infrastructure remain key pillars among the Seven Grand Promises we made to Nairobi in 2013. This is not only because it is a key ingredient for the success of a competitive modern economy, but also because welldesigned infrastructure investment raises economic growth, productivity and property values, while providing significant positive spillovers,” he stated.

MALAWI Local contractors outclass Chinese stadium projects Minister of Local Government and Rural Development Kondwani Nankhumwa has hailed local building contractor Nangaunozge for speed and efficiency in handling government contracts.

He said Malawian contractors were doing far better than Chinese contractors who had been given similar assignments. Nankhumwa made the observation when he toured the progress of the construction of the over K600 million Karonga Stadium being constructed next to Baka Research Station. Nankhumwa said that he was impressed with the only local contractor, Nangaunozge – owned by Henry Shaba, a Malawian member of parliament. “They've employed more than 100 people here, yet the other contractors have employed less than 50,” said Nankhumwa. Ironically, a few weeks ago, Nyasa Times published a stor y by local groups who blamed Nangaunozge for “sluggishness and lack of seriousness”. Kossam Munthali of the Karonga Stadium Committee had warned of unspecified action regarding Nangaunozge on the matter.

The Nigerian federal government’s plan to raise a $25 billion infrastructural fund from the global community and establish long-term bankable projects is gaining traction, according to Vice-president Yemi Osinbajo. Explaining the idea of the fund to a delegation from the Lagos Chamber of Commerce and Industry, Osinbajo said the Nigeria Sovereign Investment Authority, which manages the country's sovereign wealth fund, is leading the project. He added that the infrastructural fund would create opportunities for commercial partners to participate in the building of the nation's infrastructure alongside the federal government. This would be done through the establishment of bankable projects that involve such commercial partners. Osinbajo disclosed that the China-Exim Bank has agreed to

ZAMBIA $7 billion spent on rural infrastructure The Zambian government has spent more than $7 billion on infrastructure development to attract investors across the country. According to Information and Broadcasting Services Minister Chishimba Kambwili, the government has prioritised infrastructure development. “Government has done a lot in terms of infrastructure development to attract investors. We have embarked on a project to construct roads, as well as health and education facilities,” he said. Kambwili said the Link Zambia 8 000 project was aimed at linking provinces and districts to ease movement and transportation of goods. He said that Link Zambia 8 000 was a long-term project and that all provinces had recorded infrastructure development.

RWANDA Rwanda signs up Dubai Port The Rwandan government and Dubai Port World (DPW) recently signed a concession agreement that will see DPW develop and operate the Kigali Logistics Platform (KLP) destined to be a dry port. “This agreement will help to reduce transport costs and increase profits for businesses," said Francois Kanimba, Rwanda’s Minister of Trade and Industry. The KLP is expected to not only improve the existing logistics infrastructure in Rwanda but, leveraging its central position, will also help to position the platform as a transit hub for neighbouring countries,” Kanimba said. The move to establish the KLP will create a logistics hub in Rwanda and help to provide a consolidated volume of imports. With this infrastructure, the turnaround time of trucks and containers is set to be reduced significantly, thereby reducing associated transport costs.

Speaking during a tour of the road and the bridge, Transport and Infrastructure Development Minister Joram Gumbo said both projects would be commissioned in March. He said the construction of the bridge and the resurfacing of the road were done in an effort to increase trade between Manicaland and Mashonaland East, especially for farmers. Minister Gumbo told journalists that government was prioritising infrastructure development because it was in tandem with Zim Asset’s goal of empowering people. After touring most of the country's roads, he said he realised that they were in bad shape and required urgent attention. When asked about the winning tender for the dualisation of the Beitbridge-Harare and Harare-Chirundu highways, Minister Gumbo said government would reveal the winners in due course. The dualisation costs of the highways range between $1.5 billion and $2 billion, including the construction of the Harare ring road.

I spent 15 years as chief executive in both South Africa and Africa and, for the last three years there, held the position of CEO of ABB UAE and the Middle East, except Saudi Arabia. The main focus of my work, historically, has been in the power and industrial sectors.

IMIESA March 2016

I have been involved in almost every significant, large-scale electrical project in Southern Africa and numerous large industrial projects, so this experience falls very much in line with my new post here at AECOM.

Having most recently worked out of the Middle East, and having acquired significant international experience throughout your career, do you still see yourself as an African with a finger on the pulse of the continent's needs? My heart and commitment will always lie in Africa, and I have spent the majority of my professional life working on the continent and in South Africa, in particular. After three years outside Africa, I'm very excited to be back. Growing up and living in Mozambique until the age of 30, through decolonisation and independence, strongly informed my worldview and provided me with first-hand experience and insight into the infrastructural development needs of the African continent. It is also on the back of this experience that my passion is borne – a passion for the development of Africa.

What are your goals for AECOM in Africa and how do you think your passion will serve to achieve them? My goals for the company are twofold, yet very simple: we aim to develop Africa while

developing AECOM in Africa. As African nations seek to develop further, AECOM is able to assist with the majority of the supporting infrastructural requirements associated with economic growth. AECOM is built to build a better world, and I can't think of a better place to start building this world than Africa, which so dearly needs improved infrastructure and industrial capabilities. The company has seen rapid growth over the last few years – both naturally and through strategic acquisitions – and we aim to continue this positive trend into the future. My personal passion and my vision for developing Africa are completely synchronised with the company's vision and goals – this alignment underpins my ability to get the company to where it needs to be and it is truly fortunate that AECOM's areas of expertise largely fall in line with what Africa needs from an infrastructure development perspective.

Looking at South Africa, what would you say is the most important and economically beneficial infrastructure to develop further? South African infrastructure's developmental requirements are mirrored across much of Africa, with road infrastructure being the most in need of further development. The South African government has done much work recently on the country's road systems, with notable highlights being the improved

HOT SEAT

highways around Gauteng, spurred on by the 2010 FIFA World Cup, and the development of the N4 national route linking with the Maputo Corridor. This latter development has significantly increased two-way tourism between Mpumalanga and Mozambique as well as improved an arterial, cross-border goods transport route. Developed road infrastructure takes people to places they've never been before, creates employment and links towns that have been historically poor and isolated to important nodes, promoting greater regional connectedness. The development of rail is undoubtedly also connected to economic growth and enables dedicated goods transport lanes, promoting efficient trade and transport.

Electricity generation and adequate supply are also vital to economic development. What is your take on the current power situation in Africa? If we look at South Africa, in particular, the post-apartheid government has done an exceptional job of electrifying households. Since 1994, over four million households have been electrified and South Africa boasts a 75% to 85% rate of access to electricity â€“ a remarkable achievement considering that less than 50% of households were electrified in the early 90s. Once South Africa has some excess generation capacity again, I expect to see an even greater increase in the rate of electrification. North Africa is even more impressive and boasts a near-100% access to electricity. The situation, however, is far bleaker in Africa's more central regions, where only around 25% of households have access to electricity â€“ an unacceptably low rate. Studies by the World Energy Council have found a direct correlation between access to electricity and national wealth, and much work needs to be done in Africa to provide significantly increased electrification.

Are there any other fundamental infrastructure requirements that would spur on economic development in Africa? Having mentioned roads, rail and electricity supply as requisite economic drivers, the keystone that holds development and basic human sur vival in the balance is access to water. Countries such as Angola and the DRC have some of the continent's biggest rivers flowing through them, but this does not necessarily translate to widespread access to water. There is a clear need across Africa to construct dams, improve irrigation and provide access to underground water â€“ all areas in which AECOM has vast experience. Sanitation is also a basic human right and should always be considered a part of a holistic water provision strategy.

What areas of infrastructure development will you be targeting across Africa, in particular, with the goal of growing the company? Will the company still largely be based in South Africa? My aim is to grow the business to the greatest extent in the transportation, power, water and sanitation sectors. My extensive experience in power infrastructure will, in part, inform our strategy and, as far as water and sanitation are concerned, AECOM is fortunate enough to have arguably the greatest expertise and highest number of water engineers in South Africa. Africa has a definite need for increased power generation and electrification rates, as well as significantly improved water retention and reticulation. AECOM has vast in-house expertise in these areas. We will most certainly use South Africa as our technical base, because we already have an abundance of experts working here. Our plan is to use South African talent to develop the rest of Africa.

What do you feel is the best way to nurture and develop talent in the consulting industry, and how does AECOM hold on to this talent? Before looking at developing talent, I must point out that it has become increasingly difficult to acquire new, experienced personnel because the world has become an increasingly globalised society. You are no longer only competing with local companies for the pick from the local talent pool, but rather with companies from across the globe. Concerning the question at hand, if you develop and nurture talent, I feel you have a better chance of retaining it. At AECOM, we tr y to offer our staff the opportunity to work in any countr y, in any job. We tr y to offer such flexibility for our employees that they have no need to leave the company to satisfy desires to branch out or work internationally. We've had numerous young engineers who have gone to Doha Port, for example, to develop skills for up to a year and then return to South Africa, equipped with knowledge of international projects, ingenuity and best practice. These insights are then brought back to South Africa, to the benefit of the African continent. AECOM also trains customers' personnel by bringing them into our internal teams. These people can then return to their employers equipped with the skills to positively impact customer operations. We do a lot of this training with public sector customers, building capacity in SOEs and municipalities, in particular.

Fast-tracking an energised Africa

The Fourth Industrial Revolution is about the convergence of man and machine, and technology is the key driver of this, according to the World Economic Forum. But, on a continent where more than half of the population does not have access to electricity, what does this mean? BY LIESL FRANKSON

CCORDING TO A PANEL of African heads of state who met in Davos, Switzerland, earlier this year, this is Africa’s next challenge. In order for the continent to take its place in the Fourth Industrial Revolution, it will have to focus most of its resources on the development of energy and energy infrastructure. To tr y to solve this problem, the African Development Bank (AfDB) is leading an initiative known as the New Deal on Energy for Africa. The initiative aims to grow energy funding and partnerships in Africa to help solve the continent’s energy deficit by 2025. A recent analysis by Frost & Sullivan shows that Africa’s demand for energy is expected to grow to 930.4 million tonnes of oil equivalent by then, which is more than double the current demand. The mining and minerals industr y will be the bulk consumers of energy by 2025.

plant will provide clean electricity for more than one million people, helping Morocco reach its goal of generating 42% of the country’s energy needs from renewable sources by 2020 and 52% by 2030. “This project means more, cleaner energy for Morocco and potentially the rest of Africa,” says former United States Ambassador to Morocco Edward Gabriel. The next phases (Noor 2 and 3) are due to open in 2017 and 2018, respectively. Another project that has major implications for energy generation and distribution on the continent is the DRC’s Grand Inga Dam Hydroelectric Project. The project is the world’s largest proposed hydropower scheme, expected to generate 40 000 MW. It is a priority for a number of African development organisations, according to internationalrivers.org. Some of these organisations include the New Partnerships for Africa’s The recently inaugurated Noor concentrated solar power plant will provide clean electricity to more than one million people

Development (NEPAD), Southern African Development Community, East African Power Pool, and Eskom – the continent’s largest power utility.

Joint development The project will be constructed in six phases, according to a feasibility study conducted between 2011 and 2013 by partners Aecom and Électricité de France. South Africa will be the principal buyer of power from the Grand Inga Project, following the signing of a cooperation treaty between the two countries in 2013. According to the treaty, South Africa and the DRC will jointly develop the Inga III Dam, and South Africa will purchase 2 500 MW of the total 4 300 MW generated. According to internationalrivers.org, the DRC relaunched the process for the selection of a developer and established the first stage objective of the Inga Dam – to lay the foundation stone in October 2015, following the signing of the treaty. “A number of consortia – including Sinohydro and the Three Gorges Corporation from China; Actividades de Construcción y Servicios,

Eurofinsa and AEE from Spain; and DaewooPosco from Korea – are currently bidding for selection as developers of Grand Inga. The terms of reference for the Inga III social and environmental impact assessment (SEIA) studies were posted in early July 2013 for public comments. These studies should be concluded within a year and construction is planned to commence in 2016.”

The nuclear energy conundrum Closer to home, the question of nuclear power as an alternative source in the South African energy landscape is becoming more of a reality. In his 2016 State of the Nation Address, President Jacob Zuma reaffirmed that the nuclear energy expansion programme remains part of the country’s future energy mix. “Our plan is to introduce 9 600 MW of nuclear energy in the next decade, in addition to running Koeberg Nuclear Power Station.” The debate regarding whether or not nuclear energy is the right option for South Africa has been heated. However, some nuclear industry experts believe this is the wrong question to ask.

Sensitive but strong

The DRC’s Grand Inga Dam Hydroelectric Project, the world’s largest proposed hydropower scheme, is expected to generate 40 000 MW

“Nobody in nuclear is saying that we should only be focusing on nuclear; we are saying that South Africa needs an energy mix, of which nuclear forms a part,” said Knox Msebenzi, managing director, Nuclear Industr y Association of South Africa in the runup to the Africa Energy Indaba. “In that diversified portfolio of energy assets, 17.8 GW has been allocated to renewables and only 9.6 GW will be allocated to nuclear. We are saying that South Africa needs an optimum mix and we must not put all our eggs into one basket.”

The right funding South Africa is sometimes compared to Europe when it comes to questions about why a nuclear build programme has been chosen. “South Africa cannot compare itself to Europe’s economies, which are highly industrialised and have 100% electricity penetration, some of whom have taken political decisions to decommission their nuclear power plants. Our economic structure and needs are entirely different and we need access to large amounts of baseload power to boost our economy.” Msebenzi admitted that a nuclear build programme will be capital intensive, which is why it is critical to get the right funding with low interest rates. “The financing model is critical. Government’s Renewable Energy Independent Power Producer’s Procurement Programme is a world-class one with excellent financing models, and the nuclear build programme can also be exceptional. “There is a school of thought that estimates that 70% of the nuclear build programme will be sourced locally in value. It will reinvigorate the nuclear industr y, boost skills, create whole new industries and, thereby, create employment. The nuclear build programme can also be viewed as a regional power plan that will see South Africa supplying cheap electrical power to the region,” Msebenzi noted. On this note, President Zuma told Parliament that the government will only procure nuclear on a scale and pace that the countr y can afford. “We will test the market to ascertain the true cost of building modern nuclear plants,” he said.

IMIESA March 2016

MS The recent drought in South Africa and across other parts of the continent is having a significant impact on water supply – a serious issue that has huge implications for millions of people. Combined with that is the problem of non-revenue water (NRW), which consists of all apparent and real water losses plus unbilled consumption. Across the continent, this is still far too high. In South Africa, NRW has recently been estimated at almost 37%, while as much as 20% of all water sourced and purified in the country is lost due to leaks alone. This clearly highlights the significant opportunity for rapid infrastructure improvements in water provision and flow. If we can reduce our country’s NRW by just 8.3%, we would have one month’s additional water supply every year.

What role does smart metering play in water conservation, particularly in light of South Africa’s current water insecurity? MS The words “smart metering” are loosely bandied about in the industry and require some clarification. Simply put, a smart meter is a measuring device that is capable of communicating data to a remote interface at regular intervals. In its basic form, smart metering refers to automatic meter reading (AMR) but, in reality, that over-simplifies what is usually quite a complex system. Prepayment metering is another form of smart metering and Elster has been an industry leader in this field with more than 150 successful global implementations over the past 16 years, allowing utilities to reap the benefits of reliable prepayment metering technology.

ABOVE The H5000 is the world's most accurate, commercial smart-ready turbine meter BELOW The Q200 is the next generation of intelligent water metering

SS This is really important because, by being able to more accurately track and manage customer consumption, a municipality’s resourcing planning, demand forecasting and revenue all become a lot more predictable. Smart metering with a centralised command and control centre can also assist with detecting leaks early and managing the so-called “non-technical losses”, utilising simple mass-balancing tools and algorithms. We see this across many of the sectors in which we operate, with customers in a wide range of industries seeking ever greater operational predictability. Having the expertise to be able to deliver that in water and energy metering is a huge asset. MS Accurate, reliable meters are vital to measure and understand where water losses are occurring in order to secure a sufficient and reliable water supply. But, if it were straightforward, then every supplier in every country would have rolled out smart metering years ago; it’s not even that the latest metering technologies are hard to come by – the technologies themselves are readily available. The challenges lay in areas such as system interoperability, data privacy

INDUSTRY INSIGHT

and, in some cases where accuracy is not sufficient, demonstrating return on investment. That’s why good-quality, reliable and accurate basic metering, augmented by more advanced solutions, where necessary, provides the best cost-to-benefit ratio in the industry.

What are the advantages for clients in choosing Elster smart metering solutions? MS Elster Kent manufactures and supplies a full range of meters and related systems, spanning mechanical, electronic and hybrid meters and solutions, such as automatic meter reading, advanced metering infrastructure, water management devices and prepayment solutions. It was Lord Kelvin who said, “To measure is to know.” I’d actually take it a step further and say that to measure accurately is to know. This is what we pride ourselves on at Elster Kent. Our systems enable utility providers to make betterinformed and optimised data analyses and decision-making in areas such as water balance, leak detection, water losses and NRW. They also help to provide more accurate billing and enhance revenue collection.

What are the advantages of smart meters for water in terms of preventing water loss though nonrevenue water? MS Smart meters can provide real-time data that enables utility providers to proactively manage and optimise their reticulation systems. If managed effectively and efficiently, this information can be used to reduce NRW and provide other valued benefits through improved meter reading performance – in terms of efficiency and accuracy, and reducing meter reading costs – as well as proactive leak detection, energy savings through reduced water pumping (due to reduced water leakage) and meter or reticulation tamper detection. They also provide more accurate information to end consumers, helping them better manage wastewater and identify leaks faster.

How will Honeywell’s acquisition of Elster change customer experiences when it comes to service delivery? SS Elster was a great acquisition for Honeywell for many reasons, including its expertise, leading position in what is a rapidly developing sector and the fact that it is known in the industry for quality products and service. The customer experience will continue to be based on high-quality service from technologies that solve some of their most complex problems. The big difference will be the availability of an even more comprehensive suite of connected technologies that span users’ operations, with a significantly wider spectrum of products and solutions and at a far larger scale than Elster customers have experienced in the past.

How will the acquisition better position you to enter meaningful partnerships with the public sector? SS Honeywell has been working in Africa for many decades and, like Elster, has been highly successful in forming partnerships with the public sector. Honeywell’s technology portfolio is extremely broad, spanning everything from building management systems to process controls to solar water-heating systems to fire safety, and Elster opens up even more of the market to us. Such a broad portfolio

represents a compelling and attractive solution for many large-scale industrial projects and, through this, we have been able to firmly establish Honeywell as a trusted, reliable provider to numerous public sector customers across the continent. We are also extremely proud of Honeywell’s BBBEE performance in South Africa and are very pleased to see that Elster brings with it a strong BBBEE scorecard that has a balanced focus on both community and business empowerment.

What does the future hold for you? SS The future looks great. The integration of Elster into Honeywell’s portfolio is going smoothly and we are busy targeting opportunities to demonstrate the value of our combined solutions offering. We’re already hearing the market respond positively to this proposition and, consequently, we can be confident of, and excited about, our future with Elster as part of our business in South Africa. It is an important market for us, where we can continue to develop, manufacture and ensure fiscal quality calibration of our water, electric and gas metering solutions. We’re looking forward to expanding this in the near future and playing our part in the continued local manufacturing and export that South Africa desperately needs.

WATER WEEK | DIVISIONAL COVER STORY

Holistic wastewater Established in 1976, Tecroveer has a 40year track record of service excellence. IMIESA talks to director Piet van der Merwe about the technologydriven company’s turnkey solutions for all wastewater-treatmentrelated industries.

FFERING A HOLISTIC solution, including the design and supply for each specific application, Tecroveer prefers not to offer package plants that are a predetermined solution for a specific application, but rather create fit-for-purpose solutions to meet the unique needs of its clients. Utilising as much of the existing infrastructure and equipment as possible, and integrating this into the holistic solution, offers both capital and lifecycle cost benefits. Van der Merwe emphasises, “We take our commitment to clean water for future generations very seriously.”

IMIESA March 2016

Speaking of the current water crisis in South Africa, Van der Mer we explains that, “If you have a system, the system’s integrity only gets tested under stress as is currently the case. We are well positioned to offer our clients both short- and long term solutions for systems that are failing under stress." What provides Tecroveer with a competitive advantage, he explains, is the company’s combined expertise that provides holistic solutions: “We have a number of international patents, and what we strive to do is combine civil, mechanical, electrical and process aspects in order to provide the best possible, complete turnkey solution to our clients.” Furthermore, Tecroveer is able to provide all the necessar y equipment needed for sewage treatment, wastewater treatment or industrial water treatment of mine-affected water plants. “In doing that, we ensure that the solution we design with the client or engineer is the best solution for long-term water treatment. “The solutions that Tecroveer has that specifically address current issues of water shortages and poor water quality are ideally positioned to solve a problem in such a way as to provide long-term solutions rather than patchwork, quick fixes. “We can take an existing plant that is operating over capacity, or possibly run down from

a lack of maintenance, and we can implement a solution to upgrade and repair the plant to operate at maximum efficiency, in a ver y short time. We are able to address either the hydraulic or organic treatment shortcomings of the plant by implementing an innovative solution.”

Maintenance and operation To assist clients with their maintenance and operation requirements, Tecroveer offers maintenance and operation contracts, taking over these responsibilities from a client while empowering, upskilling and training their existing staff. This ensures the future sustainability of the treatment process and plant. “At this stage, we are responsible for the operation of more than 15 wastewater treatment plants across the countr y.” Many municipalities will specify the requirement for this kind of contract at the tender stage, owing to the difficulty presented by procurement processes to repair a plant retrospectively.

eMalahleni refurbishment projects Because of Tecroveer’s in-house process, civil and mechanical capabilities, it is able to upgrade plants with fast turnaround times. This is exemplified in the recent refurbishment of a number of wastewater treatment plants in eMalahleni since July 2014. The plant at River view was

This efficiency is monitored by independent laboratories (before and after results) where they were not complying with general limits before, they are now complying above and beyond the required standard. “The old works were decommissioned at the same plant. We refurbished the whole plant, all dysfunctional equipment was repaired or replaced, and we were able to meet all effluent standard requirements prescribed by the Department of Water & Sanitation. The entire

project took two months, while Naauwpoort WWTW, where we started work in July of the same year, took about three months,” explains Van der Merwe.

Research and development The Tecroveer group of companies has a proud history of redefining wastewater treatment processes in South Africa, owing to their commitment to ongoing research and development. Tecroveer’s worldwide patented transfer mixer, for example, does away with a lot of maintenance and is extremely energy efficient. It combines the mixing and process recycling requirements into a single unit. Tecroveer is a specialist supplier of longlasting, rugged equipment for South African conditions. Upgrading plants is a tricky business, states Van der Merwe, “Sewage keeps on flowing, you can’t bypass it, you work while the plant is still treating sewage.

A bulk supply lifeline The Shemula Bulk Water Supply Scheme upgrade is a government initiative to create a sustainable solution to the uMkhanyakude District Municipality's (KwaZulu-Natal) water shortages. As part of this project, the Shemula Water Treatment Works, Phase 1 of the multiphase project, has been constructed to produce 20 Mℓ/day of potable water for the region. BY BEATRIX KNOPJES

HE SHEMULA BULK WATER Supply Scheme forms part of a larger plan in the area to rectify water shortages. Assisted by the installation of bulk water and reticulation networks, it will supply potable water to 134 864 people within 16 200 households. Phase 1 of the Shemula Bulk Water Supply Scheme has been the upgrading of the Shemula Water Treatment Works. According to Mike Croeser, technical director, UWP Consulting, the consulting engineers on the project, “The uMkhanyakude District Municipality is currently reviewing the bulk water supply schemes within the district. UWP Consulting was appointed in April 2011 to commence with the planning of the Shemula Water Supply Scheme upgrade – an R845 million bulk water supply scheme to satisfy the needs of some 230 000 people living in the northern half of the Jozini and uMhlabuyalingana municipalities.”

Design specifications “The Shemula WTW has been designed to have a capacity of 40 Mℓ/day, with a 25% redundancy, thus allowing for up to 50 Mℓ/day ultimate capacity by 2035. The current demand is approximately 12 Mℓ/day and is only expected to reach 40 Mℓ/day by 2025,” explains Croeser. The project was not without its challenges. As Croeser explains: “Poor geotechnical conditions highlighted during the geotechnical investigation presented a challenge

during construction, where colluvial sands with a very high collapse potential had to be removed to at least 2 m below the founding level and replaced in layers compacted to 95% mod AASHTO.” Construction on the project commenced in 2013 and was completed in July 2015. While it was the intention that the new WTW would simply transfer the existing water-use licence, this became an issue when it appeared that the existing licence did not exist. “A water-use licence application was made for the ultimate capacity of the new works in January 2014 and this was approved by the Department of Water & Sanitation (DWS) in December 2014,” explains Croeser. Apart from marula trees, which are protected, there were no particularly important environmental constraints. “The design attempted, wherever possible, to avoid marula trees and, during construction, care was taken not to damage trees that were within the general works area but did not need to be removed,” he says. The construction of the new raw water pumpstation required extensive excavation, which impacted on the river bank. This was successfully rehabilitated with the use of gabions to the satisfaction of the environmental control officer.

Project design Phase 1 of the project was completed during July 2015 and includes the following main elements:

design and construct (EPC or turnkey) tender. At this stage, certain elements of the design had reached an advanced stage and it was decided to split the contract into two sub-phases. Phase 1A was let as a conventional EPCM contract and included the raw water pumpstation and rising main, the clear water storage reser voir and the clear water pumpstation and rising main. Phase 1B was let as an EPC contract and included the full water treatment works design and construction. The design of Phase 1A was carried out entirely by UWP Consulting while the design of Phase 1B was carried out by the contractor, Veolia-Icon joint venture with Eaucon Water as the specialist mechanical and electrical contractor. UWP Consulting prepared a detailed specification for the design of the water works which was used in the turnkey tender to ensure that a state-of-theart facility was provided under the EPC contract. The raw water pumpstation has been designed as a dry well and consists of a 9 m deep x 7 m diameter concrete structure embedded in the left bank of the Pongola River with a 1 m diameter pipe extending into the river flow. Generally, the flow in the river is kept constant, at around 5 cumec, by means of controlled release from the Pongolapoort Dam some 60 km upstream of the works. However, in September of every year, DWS releases a controlled flood which peaks at 600 cumec. During the flood, the water level in the river is approximately 2 m below the roof of the raw water pumpstation. "Apart from the critical potable water supply, this project is also geared towards connecting districts and educating the rural communities on the importance of water conservation, and on the correct process to extract clean water from the source," says Blake Cooley, project engineer, Veolia Water Technologies South Africa . The water works has been designed such that certain elements have been sized for the ultimate capacity in order to facilitate a simple upgrade from 20 Mℓ/day to 40 Mℓ/day, when demand dictates.

Total treatment solutions Eaucon Water SA prides itself on being a company that specialises solely in the water and wastewater treatment sector, with an emphasis on the municipal market. Gordon van den Heever, managing director of Eaucon Water SA, outlines the company’s capability for delivering turnkey solutions – from start to finish.

AUCON WATER STARTED out as a filtration specialist and evolved into a company that can specifically design for any application in the water and wastewater sector, whether for refurbishment or greenfield projects. South Africa’s challenges in the water treatment sector can be resolved with the use of innovative technology, Van den Heever explains: “The industry needs to be more open to innovative designs, instead of the current systems that have been part of the industry for the last 50 years or so. We find that most refurbishment projects are being done in a manner where existing equipment is only replaced. In actual fact, the time and money spent could be put to better use by rather focusing on enhancing the process and throughput at the same time.”

In-house capability Eaucon is ideally positioned to deliver these innovative solutions. “We have an in-house engineering team that can effectively and efficiently handle engineering challenges in all disciplines of this sector,” says Van den Heever. These include: • process engineering • mechanical engineering • electrical engineering, complete with automation.

Eaucon has its own in-house manufacturing facilities and manufactures its own proprietary equipment dedicated to the water and wastewater industry. “We have in-house specialist mechanical and electrical erectors who are trained to execute projects in a professional manner, timeously, and with a focus on quality,” he says. Van den Heever continues, “Our equipment is in high demand and the fact that we can design specifically for any application helps us build relationships with key individuals for future projects.” This in-house capability sets Eaucon apart from its competitors. “Eaucon Water is not just another project house. Yes, project management and engineering form a big part of our business, but we also have a full-blown fabrication facility with all our fabricators and welders certified to the ASME 9 and AWS D1.1 codes, with regular recertification,” explains Van den Heever. Production is executed under strict quality control and all work is witnessed and released by third-party inspectors.

maintenance of Eaucon’s water treatment works. “We ensure that all environmental safeguards and regulations are strictly adhered to and that executing projects has no negative impact on the ecology and environment,” insists Van den Heever. Undertaking projects in South Africa can be a challenge. “With reference to the Australian municipal water sector, the contractors and consulting firms are part of the same team from project initiation until completion. By doing it this way, I believe projects can benefit more than having separate entities working on their own project goals,” he states. Eaucon Water SA is in the unique position to be able to provide a total water treatment solution to its clients. “From design phase right through to fabrication, commissioning and project close-out, we have the in-house expertise to expertly and efficiently handle each stage of implementation along the way. We are a one-stop shop!” concludes Van den Heever.

Committed to sustainability Eaucon is committed to sustainability, not just as a watchword but as a real concept with real consequence. Sustainability is a major consideration in the planning and

Fostering collaboration Royal HaskoningDHV has engineered its operational business structures to unlock significant potential. NICHOLAS MCDIARMID meets with Anke Mastenbroek, director: Water, Royal HaskoningDHV, to find the link between this restructuring and South Africa’s water sector, and what this illuminates about the sector’s current challenges.

ONTEXT IS critical,” Mastenbroek enthuses. “Every project we do exists within a changing and increasingly unpredictable environment. We understand the local context and deliver appropriate, local solutions.” Royal HaskoningDHV’s decision to design a simpler structure from which to operate is a response to global dynamics, and Mastenbroek quotes board chairman Erik Oostwegel, saying: “Our clients operate in an increasingly volatile and complex environment, and simplifying our internal structure helps us to serve them with even better, future-proof and integrated consultancy services. “Combining related disciplines into a leaner structure helps us to boost internal collaboration and knowledge sharing. In addition, closer alignment between global and local teams, through the regional structure, helps us to respond to market opportunities effectively and efficiently.”

IMIESA March 2016

Simple connections for meaningful innovations “Dialogue is always the place you have to start from,” says Mastenbroek. “No single solution will work – certainly not in isolation.” She places strong emphasis on the problem of thinking infrastructure itself is going to fix problems: “The concept is bigger than the infrastructure. What about the people using it, and living around it?” Royal HaskoningDHV is adamant that its engineers join the dialogues, as the experience of community members must be included in the attitude and approach of what they eventually design.

Closing the loop – structures reflecting natural systems “Royal HaskoningDHV asks four questions about the design of every project it undertakes,” Mastenbroek elaborates: • Does it meet the requirements of most stakeholders?

TOP Welgedacht WWTW ABOVE Anke Mastenbroek, global business line director: Water

•D oes it add additional value for the client and society as a whole? • Is it future-proof? • Can we meet the client’s demand while using minimal natural resources and energy? “Our focus is on finding the simplest and most complete solution – not the most expensive one,” Mastenbroek emphasises. “First, optimise the water infrastructure that is already there. Also, look at how the community behaves and how this can change the

infrastructure assumptions. If an inter vention isn’t designed to include the complete water cycle, what you end up with is not really infrastructure at all; you end up with standalone components that cannot possibly function in a meaningful, sustainable way.” The closed loop Mastenbroek advocates is essential to the valuable supplementar y resources that are vital in the development of an infrastructure system. She includes human behaviour as possibly the easiest to modify in times of emergencies. “You have to close the loop in order to scale temporar y inter ventions instead of constantly building from scratch. It also means the introduction of alternative water resources and innovative solutions such as desalination and reclaimed water, which offer sustainable and secure water supply. These solutions can be cost-effective, if we apply best practices for optimum water resource portfolios combined with proven technologies.” Royal HaskoningDHV’s structural commitment to collaborative development is realised by simple principles, alongside a multidisciplinar y review process, which sees a variety of perspectives in response to standard criteria, delivering insights that no single department or engineer can arrive at alone. Is Mastenbroek’s description of Royal HaskoningDHV an impossible adaption in South Africa’s public sector? “Innovation is a collaborative process, inspiring our colleagues and our associates,” notes Mastenbroek. “We want to engage with clients, partners and governments to lead the discussion and to make meaningful contributions.”

Fostering collaboration with simple structures In building the best teams, Royal HaskoningDHV is developing a culture that suppor ts innovation and maximises cocreation. It applies the innovation funnel to do the right things in an efficient way. “We are sharing and commercialising product and process innovations to achieve leading market positions. “Innovation helps our business thrive through renewing and adapting our products, ser vices, business models and processes,” Mastenbroek insists. “The resulting solutions are quicker to implement, safer, of higher quality or more sustainable. They may also require fewer resources or produce fewer emissions. ”Those who are brilliant in their own specific areas tend to find each other, and academic input always brings something different as well,” says Mastenbroek, explaining the elements of innovation in more natural terms than commonly pursued. “It took 10 years to move our Nereda wastewater treatment technology from research and development projects to actual pilot plants,” she says, adding that the creative process is not rigid, and that for ever y 100 ideas, perhaps only as few as 20 will reach a point of application.

A knife’s edge “We are in such a precarious situation,” stresses Mastenbroek, referring to the drought conditions South Africa is facing. “Water availability is one of the most decisive factors of any nation’s economic, social and environmental well-being, and the next 10 years will see this being South Africa’s greatest challenge.” Mastenbroek stresses the inability of isolated infrastructure inter ventions to provide

real solutions: “South Africa now has to innovate at all points of the water cycle; it must reduce demand, but also find ways of making more available from outside the traditional sur face and groundwater resources, which are almost completely utilised at this point.” Mastenbroek lists the points of inter vention as: • water-loss control • water-use efficiency • a ugmentation and protection of local resources • efficient water reuse • desalination • inter-basin transfer schemes. “The general focus on domestic, industrial and mining water consumption, and efforts to reduce that demand, is not to be dismissed. But, the fact is that 60% of the available resources are actually used by the agricultural sector,” Mastenbroek cautions. Royal HaskoningDHV is excellently positioned to close the water cycle of domestic, industrial and mining water, but the agricultural challenge is clearly most threatening. “We have focused heavily on the complexities of food security, and South Africa now cannot avoid the consequences of what has already happened,” she notes. “The reality of climatological drought conditions in five provinces means the shortages are coming.” The recent droughts are a strong and present indicator of the impacts climate change can have on our communities and the future of South Africa as a whole. Royal HaskoningDHV is leading the way through its relentless commitment, stronger collaboration and innovative technologies, and urges the rest of the water sector to join together to build a resilient and sustainable water cycle. Royal HaskoningDHV has contributed to the development of South Africa, and that of Africa, for 93 years. As a global company, its linked network of expertise and experience connects 6 500 people, working with clients in 130 countries on projects that have improved living conditions for many people.

In 2011, South Africa promulgated the Green Economy Strategy, which identified water management as one of eight key focus areas. The National Development Plan (NDP) 2030 also highlights projects for completion between 2017 and 2020 within the investment programme for water resource development, reinforcing this concept.

Every clean drop counts

HE DEPARTMENT OF Water and Sanitation (DWS) is governed by two acts, namely the National Water Act (NWA) of 1998 and the Water Services Act (WSA) of 1997. According to a Market Intelligent Report by GreenCape, the NWA redefined water rights in South Africa and established a new framework to mandate and regulate water resources. The WSA, promulgated in 1994, defined the role of the DWS as regulator, the role of water boards as bulk providers, and the role of municipalities as service providers. Each of these bodies is responsible for overseeing a different aspect of the South African water landscape and, at times, the lines are blurred between the responsibilities. Ultimately, all of them are striving towards the same goal, which is to ensure

that all South Africans have access to clean, running water.

The Department of Water & Sanitation The DWS oversees and regulates the water business through appropriate policies and regulations, which are implemented through its nine provincial offices and four water management clusters. It operates at national, provincial and local levels across all elements of the water cycle (i.e. from water resource management, water abstraction, water processing and distribution of potable water, wastewater collection, to treatment and discharge). The DWS also monitors the per formance of the sector and regulates drinking water and effluent quality against industr y standards and recommends changes to the business environment within which the various role players have to per form. The DWS owns most of the large dams and related water resource infrastructure and under takes the necessar y planning and implementation of future water resource development projects. To direct the execution of the department’s many functions, the second

National Water Resource Strategy (NWRS), published in 2012, was developed to inform the implementation of the NWA. The NWRS has three key objectives, which are to: (i) increase the contribution of water to the economy and job creation; (ii) protect, develop and control water resources in a sustainable and equitable manner; as well as (iii) support the elimination of poverty and inequality. There are multiple role players who assist the DWS in delivering on its mandate, including the following: • National Treasury, which financially supports DWS • the Depar tment of Cooperative Governance, which ensures local government provides water services, regulates

Water services authorities The DWS defines a WSA as any municipality that has been assigned the responsibility for ensuring access to water ser vices. They are responsible for planning, implementing and operating the necessar y infrastructure to provide effective, affordable and sustainable water ser vices to their customers. Of South Africa’s 278 municipalities, only 152 are WSAs, according to the DWS. The Eastern Cape has 16 WSAs, the Free State 20, Gauteng 10, KwaZulu-Natal 14, Limpopo 11, Mpumalanga 18, the Northern Cape 27, North West 11, and the Western Cape 25. According to the department, a WSA may perform the functions of a WSP and may also form a joint venture with another water services institution to provide water services. “In providing water services, a WSA must prepare a water service development plan (WSDP) to ensure effective, efficient, affordable and sustainable access to water services. The WSDP should be in line with the catchment management strategy of that water management area. The plan provides a linkage between water ser vices provision and water resources management.”

South Africa has 12 water boards that supply a total bulk potable water volume of approximately 2.46 billion m3/annum (some 57% of the total domestic supply), have a total fixed asset value of R19.6 billion and a total operating cost of R5.6 billion per annum, according to the department’s water sector overview (2013). Water boards supply potable water to 28 million people (just over half the country’s population); however, they have a supply footprint that could reach 39 million people, (which represents approximately 11 790 communities, including several large industries). There is an institutional reform and realignment process under way in the department,

Predictable challenges to

an unpredictable resource The South African water crisis has almost become a thing of legend. The threat of “dry-outs” – electricity blackouts due to a lack of cooling water – and Johannesburg’s imminent collapse into a sea of acid mine drainage have not yet materialised. IMIESA talks to Mike Muller, former director-general of the erstwhile Ministry of Water Affairs and Forestry, who goes beyond the fear and delivers some facts.

EW WATER DELIVERY failures have actually been the result of water scarcity, explains Muller: “Even today, the chronic conditions being experienced by the areas in declared states of emergency have far more to do with municipal maladministration than they do with natural shortages.” If the goal of water resource managers is to support water security, he says, “In terms of the availability of an acceptable quantity and quality of water for health, livelihoods, ecosystems and production, coupled with an acceptable level of water-related risks to people, environments and economies – they have been successful, despite our physical and social constraints.” A well-managed water resource, says Muller, is one that considers the various social and economic backbones of South African development, the evidence of a well-managed resource is clearly presented

in the consistent supply to industries, which have been both maintained and expanded, helping to achieve broader social goals, if only by underpinning jobs and tax revenue to pay for social grants. “Consider the imminent introduction of cars powered by platinum-based fuel cells: if this takes off in South Africa, the water to expand platinum production is already available – the De Hoop Dam in the Burgersfort area is a great example of this. Not only is it ready to supply the mines in the Limpopo area, it is also catering for domestic and other industrial customers, and is highly functional,” he explains. Another example of South Africa’s sophistication in this regard is the water supply infrastructure planned for the Waterberg energy developments, based on the reuse of Gauteng’s wastewater, which is already well into its first phase of infrastructure construction.

Strengthening water security Given that such high levels of sophistication exist in tandem with a preponderance of inadequate basic services across so much of the land, the broadest challenge constitutes sustaining and strengthening water security. “The main threat is not that the country is running out of water, widespread pollution – which is not yet causing

irreversible damage – or climate change, which adds to uncertainty but will not wreak havoc on our supplies,” says Muller. The current drought is now exposing the weaknesses that lie in the municipal systems and the latest legacy, which has prioritised politics over structural considerations critical for delivery services. Water resource management is a tricky challenge: it is essentially a social and political activity rather than a technical endeavour. “While there may be technical solutions TOP AND ABOVE De Hoop Dam in the Steelpoort River Valley

to specific problems, they will only be implemented if they are aligned with social values and political priorities,” he says. China offers an extreme example of how socio-political activities and technical endeavours can be aligned. Until recently, Chinese political leadership was dominated by engineers, so water management was a simple business of looking at future needs and designing and implementing appropriate technical responses. “The gargantuan Three Gorges Dam was designed to protect the Yangtze River valley from deadly floods and to avoid lopsided economic development along the coast, by improving inland navigation. It also generates more than 20 000 MW of renewable hydropower and supports water transfer to the arid north,” explains Muller, “Given the sympathy between South Africa and China, we must surely consider the value of a technocratic leadership, which enables the system to address a complex array of technical, economic, social and environmental problems through a straightfor ward, technocratic process.”

Few places in the world are like China and, at best, water engineers influence decisions rather than make them. So, the challenge is to sustain a community of practitioners that is able to keep political and social debates technically informed. According to Muller, that is easier said than done but it is instructive to remember how our present relative success has been achieved.

Breaking a legacy “For that, we have to go back more than 40 years, when the 1970 Commission of Inquiry into Water Matters identified the critical need for a competent water administration in a

water-scarce South Africa. It recommended building a stronger water research capacity and training the best school-leavers to work in the water sector,” says Muller. He explains that those recommendations were enthusiastically implemented by Minister of Water Affairs Fanie Botha, who established the Water Research Commission and, through generous bursaries, recruited a cohort of white professionals nicknamed the "Botha babies". “They built knowledge, the hydrological information systems and, more recently, the planning processes that underpin today’s water security. “They were conceived by a National Party politician but they provided the foundation for water resource management in a democratic IMIESA March 2016

South Africa. Those 1970s initiatives are still reflected in today’s water plans that examine present trends in the wider society and the water management interventions needed to keep pace with them,” he says. The information, planning and administration of water are fundamentally important public goods that cannot easily be produced outside the public domain. So, although the apartheid state served the development needs of a minority at the expense of the rest, the example of water is still relevant to the debate about the kind of developmental state South Africa needs. “The National Development Plan has emphasised that, until South Africa has a capable state, we will not be able to create a developmental one. So, an immediate water challenge is that the Botha babies will all have retired over the next five years. How do we retain their knowledge and grow a new generation of practitioners who will face more complex problems in the future?” he asks.

Private sector capability “As society’s demands on water resources grow, we need to strengthen capacity to monitor and manage them, to develop the people who are going to do that and to sustain a collaborative working environment with the wider society. This capacity will not come from the private sector alone; private companies cannot invest in people who take a decade to gain the knowledge they need to become really productive. The private sector has always, truth be told, relied on the state to do that. A strength of the old system was that most professionals who practised in water had started their careers in government. When they moved into consulting or to the water-user sectors, they maintained relationships, trust and understanding that contributed significantly to the development of appropriate responses to our wicked challenges. This common working culture and background are fundamental characteristics of most successful developmental states.

Challenges and solutions One present danger is that South Africa’s specialised technical consulting capacity is being bought up by large, foreign firms, which have even less motivation to build local knowledge. Muller explains, “Indeed, less local knowledge merely expands their future markets. However, as firms become less local, we risk losing that critical culture of cooperation and trust.” This has become a wicked challenge in its own right, “How can we produce a new cohort of practitioners with the technical competencies but also the breadth of vision that we need? How do we produce a community that bridges the public and private sectors? This is part of the broader challenge of building relationships of trust across a deeply fractious South African society. Our history and diversity make the task no easier.”

In conclusion In the short term, stronger partnerships are needed between the government’s water administrations and those major water users and professional service providers that employ a growing proportion of South Africa’s limited technical skills. “Only if we succeed in building such partnerships will an institution such as the South African Academy of Engineers (SAAE) be able to achieve its vision of providing a source of expert advice on matters pertaining to global competitiveness and quality of life for the nation,” concludes Muller.

MR Abeco offers ground-level, elevated, special and circular tanks. Our tanks range from 1 800 litres to 10 million litres. On our elevated tanks, we design and manufacture the stands as per customer requirements. On our special tanks, we accommodate requirements where the client has space restrictions or obstructions. Our circular tanks provide an alternative to the rectangular tanks and range from 8 000 litres to 30 million litres. We have also adapted our product range to take us into the wastewater, dry bulk storage and digester markets. These tanks are supplied with either open roofs, steel roofs or aluminium geodesic domes, which are the best dome covers in the market place for water and wastewater applications.

What makes your tanks unique and how are they especially suitable to our conditions? Our galvanised tanks offer safe, hygienic water storage that is unaffected by ultraviolet or light penetration, easily transportable

to remote locations and quick and easy to install. By adding the world's best-performing interior tank lining available for water and wastewater storage applications to our range, we are able to provide unmatched performance compared to any and all exterior bolted tank coatings. The tanks are very rugged but can be transported and installed using basic equipment and manual labour.

What partnerships has Abeco Tanks established that amplify and support your product offering? When Abeco looked at adapting its product range to move into the wastewater, dry bulk storage and digester markets, the best option was to team up with the worldwide industry leader in bolted, field-weld, shop-weld and hybrid storage tanks for both dry bulk and liquid tank applications. This was achieved through Abeco’s agreement with Tank Connections to exclusively provide precision RTP (rolled, tapered panel) tanks to the African market.

What standards do you subscribe to you? We currently subscribe to the following:

• ISO 9001:2008 certification • SABS certification • ASIB approval • member of the Water Institute of Southern Africa • member of the Southern African Institute of Steel Construction • member of the South African International Steel Fabricators.

What services does Abeco Tanks offer and how does your customer engagement deliver client assurance? Having over 100 years of combined water storage tank experience, Abeco offers a unique perspective on potable water, wastewater, fire protection and industrial liquid applica-

tions. Abeco knows the merits of each type of construction, which allows us to objectively propose the right type of storage for each application. Abeco designs, manufactures, sells and installs the tanks.

What role do your products and services play in preventing water loss and mitigating drought conditions? With higher-water-consumption behaviours increasing and growing urban, domestic and industrial water usage, there is strain on the municipal water supply and a need to promote water conservation. In rural areas, piped-in water is nonexistent and water tanks provide the means to get water to the people. Planning for drought is the key point for a successful mitigation policy and – with Abeco being able to supply and install reservoirs of up to 30 million litres, in less than half the time required for concrete construction – making sure that is water available.

The Sprint range is manufactured from similar materials to Amanziâ€™s water meters and units carry a 20-year guarantee. Our suppliers form an integral part of our business and their loyalty and support create a winwin situation, whereby everyone benefits from increasing revenues.

What standards do you subscribe to? We are subject to stringent regulations. Our water meters are NRCS-approved and are individually tested in our SANAS-accredited laboratory. Our injection moulding process is ISO 9001 accredited and ISO will soon be applied in all the other functions.

What services does Amanzi Meters offer and how does your customer engagement deliver client assurance?

We are solutions driven and our R&D and product development are due to customer involvement and consultation. Our products are backed by our quality assurance and by a return-and-replace policy. This allows our laboratory to apply root-cause analysis of any possible failure caused by poor material or workmanship.

What role do your products and services play in preventing water loss and mitigating drought conditions? Fines imposed on transgressors for exceeding water restrictions are ineffective as affluent consumers can afford to pay fines instead of saving water. Our iMvubu valve allows all consumers to be treated equally and to be restricted to a predetermined volume of water. Two pilot projects installed in holiday establishments have proven to be effective in reducing consumption by 30% during the December holiday season. The system can also be used to read meters from a remote office by applying advanced technologies, such as AMR and GSM. Our iMvubu limiter valve is ideal for the dispensing of free

water to indigent communities. A unique trickle flow with a self-flushing function is being patented. By inserting a flow limiter, the trickle can be kept at a constant volume at specific pressures. AMI functions allow for two-way communication to send commands and collect data from the device. As most leaks are due to bad connections, we test all assemblies to 25 kPa for one minute. Amanzi products are associated with quality and the Isiflo Sprint range, backed by a 20-year guarantee, is recommended with our products. This ensures a proper, leak-free environment, which saves not only water but also the cost of constant replacements and repairs.

• leak detection and repair • underground services location using ground-penetrating radar.

What key advantages do your companies derive from being part of a group with a comprehensive range of skills, services and technologies?

How does your customer engagement deliver client assurance?

AK The shared services at group level, such as HR, marketing and finance, increase efficiency – especially when operating outside the borders of South Africa, in countries where HR and financial dealings can be complex. On the technical side, access to the diverse range of skills, equipment and technologies across

the group makes resourcing of projects easy and effective, and we are able to put together comprehensive project teams at very short notice. SM Our access to structural, electrical, mechanical and civil professional engineers from within the group allows us to provide a broader service to clients, encompassing in-house design-and-build solutions.

IWC Roger Rusch | CEO What specific products and components does IWC manufacture/provide and what are the quality indicators that your clients must know about? RR IWC provides a complete fluid movement and storage solution, which means we can design, manufacture and install the necessary products to move practically any liquid from point A to B and then either disperse or store it. IWC encompasses locally designed and manufactured GRP piping and liquid (water, chemical, effluent, etc.) storage solutions. We have a complete turnkey offering from engineering and design to installation and service backup. Our products and service offerings are fully customisable according to client specifications and needs.

What makes these products unique and how are they especially suitable to our conditions? GRP encompasses a host of unique characteristics, which set it apart from any other product offering, namely: • total corrosion resistance and requires no internal or external coating or wrapping • a lifespan of 50 or more years

• d esigned to handle the high pressures experienced in some water reticulation systems (our GRP pipes are typically designed around a 25 bar pressure rating) • p ipes are lightweight; for exam-

NB200 water pipe will have a 10 000 N/m² stiffness rating, which means fewer pipe supports on a specific pipeline (resulting in an overall capital cost saving in terms of installation), and also that

We offer full turnkey solutions to specific client requests. This enables IWC to continuously engage with the client so as to ensure that we not only meet but exceed their expectations and provide a

ple: an NB200, 12 m long, 25 bar pressure rated GRP pipe weighs only 66 kg as opposed to a similar PVC type pipe offering that weighs 142 kg and typically only 25% of an equivalent steel pipe; this makes them easier to handle and install • o ur GRP pipes have a standard 12 m overall length, which makes them easy to load and transport on a truck; for example: a single 12 m trailer will accommodate 72 of our NB200 pipes • o ur GRP pipes have an inherent stiffness and a typical

the pipe can be buried at considerable depth • our GRP pipes are also not affected by organic matter present in soil • the highest “C” value (Hazen Williams Coefficient) of all piping materials due to the very smooth inner surface, which gives a lower head loss and reduces the cost of pumping and, therefore, reduces life-cycle cost considerably in comparison to alternate materials • practically maintenance free • both GRP pipes and tanks are easily repaired should they be damaged; for instance, when a back actor trenches through an existing waterline, the punctured and now leaking pipe can easily either be repaired or easily replaced • large range of pipe couplings and fittings readily available.

What role do your products and services play in preventing water loss and mitigating drought conditions? Unfortunately, South Africa’s ailing infrastructure only compounds the effects of the current drought. Leaking pipes, tanks, dams and valves – you can name it – can all be prevented or even eliminated through targeted infrastructure capex and maintenance spend. Both our GRP piping and storage solutions are effectively maintenance free, if installed correctly, and offer a very long lifespan, which equates to a good return on capex spend.

MATHER + PLATT Dave Johnson | Marketing & Business Development Manager

ATHER + PLATT is a leading name in the pump manufacturing industr y of South Africa and was established locally in 1950. The company is able to offer officially manufactured spares, manufacturerwarranted repairs and new pumps, as well as the brands associated with the Mather + Platt name, such as Viking Gear pumps, Vanton chemical pumps and EIM submersible pumps.

What specific products and components does Mather + Platt manufacture/provide and what are the quality indicators that your clients should know about? DJ We manufacture a large range of pumps in South Africa, which are sold not only locally but also exported as far as Canada, the UK, Egypt and most African countries. Specifically for water systems, we manufacture split-case, multistage and end-suction pumps. These have been installed into local water authoritiesâ€™ water systems, providing water for industry and households throughout South Africa. All spares are locally manufactured to original OEM drawings and specifications. We have recently supplied six multistage pumps (1 350 m3/h and head of 35 m) to our sister company, which were installed in Walker's Ferry pump station in Malawi.

What makes these products unique and how are they especially suitable to our conditions? Our pumps are manufactured for robustness, giving a long life before refurbishment. We have

pumps that have been installed at the water authorities and kept running for up to 30 years before being refurbished. With technology and many yearsâ€™ experience, we are now able to refurbish and line the pumps with coatings that increase efficiency, reduce running costs and reduce corrosion, giving extra life to the pumps.

What partnerships has Mather + Platt established that amplify and support its product offering? We have an agreement with our sister company, APE Pumps, which has a Project Department that does the installation and commissioning of our pumps. Both Mather + Platt and APE Pumps are owned by Worthington Pumps India, from which we can obtain materials such as super duplex for pumping corrosive waters, like sea water. We have a long-established business relationship with our suppliers of electric motors, mechanical seals, bearings, etc. This has led to good deliver y and assistance from these suppliers.

What services does Mather + Platt offer and how does its customer engagement deliver client assurance? We offer a full service, from manufacture through to installation and commissioning. We are currently working on a project for an irrigation system covering 10 000 hectares. We are designing the pump station where the pumps, variablespeed drives, pipe work and valves will be installed. The pumps are being designed in our Engineering Department, using our existing models with different impeller sizes and number of stages. Final capacity will be in the region 30 000 m3/h. There will be a mix of pumps including multistage, split-case and vertical for the different levels of the system. The pipework will also be installed by APE Pumps. All pumps and associated equipment will be installed

and commissioned by Mather + Platt and APE Pumps. We have just completed the refurbishment of two 20/20 split-case pumps for Rand Water and four 24/24 split-case pumps for Harare Municipality. We also offer a ser vice for refurbishing pumps back to OEM specifications.

What role do your products and services play in preventing water loss and mitigating drought conditions? Due to the robust nature of the pumps, they seldom break down. This results in no loss of water supply to industrial and domestic properties. The pumps can be fitted with mechanical seals to prevent water loss associated with packed gland sealing.

What standards do you subscribe to? All our pumps are manufactured to ISO 9001:2008. We have in-house inspectors who inspect the raw castings pre- and post-machining. Once pumps are assembled, they are inspected again before despatch. We have a Level 3 BBBEE rating.

WRP Ronnie McKenzie | Managing Director What services does WRP offer? RM WRP has been offering specialist support in the field of water loss reduction to municipalities and industry for the past 18 years. We introduced the concepts of burst and background estimates and advanced pressure management to South Africa in the late 1990s and have pioneered the implementation of pressure control in large areas (up to 100 000 connections) through our Khayelitsha and Sebokeng installations. The company has developed various software packages, many of which are freely available through the Water Research Commission, and is currently focusing on the Zednet live monitoring and analysis package, which has been developed locally and is currently handling over 4 000 monitoring sites (flow and or pressure) in six countries. We see the monitoring of flows and pressures as the key to the management and ultimate reduction of water losses in both municipal and private water supply systems.

What is your opinion on intermittent water supply at night? Many municipalities face large water accounts from their service provider for the supply of water into areas that experience high levels of leakage often alongside relatively low levels of payment. In order to reduce water use, some water managers are resorting to intermittent water supply, where the water supply is cut off at night in order to reduce overall consumption and save money. This practice can result in some short-term savings but the disadvantages associated with such measures far outweigh

these savings. Recent research on the issue of intermittent water supply has shown: • Although initial savings in water use can be achieved, the demand will gradually increase over time due to increased leakage and, within a year or two, will exceed the demands previously experienced under 24/7 supply. • Intermittent supply gradually destroys the water reticulation network through the continual pressurising and de-pressurising of the system. • Intermittent water supply greatly increases the risk of

contamination from groundwater and/or sewage, which can increase the risk of typhoid and cholera.

What makes the Zednet monitoring solution so popular? Many municipalities and large consumers are starting to appreciate the need to monitor their water supplies on a real-time basis to identify operational problems and/or leakage as soon as possible. Through such monitoring, it is possible to pick up a new leak within a few hours, which can then be repaired within

a day or two. The alternative is to await a potentially large water account, which alerts the customer that there is a problem. The cost of the equipment and associated communications charges have dropped significantly over the past few years, while the cost of water has more than doubled, making such monitoring a highly cost-effective measure for anyone with a significant water account. Zednet is designed to provide a reliable and user-friendly monitoring solution, which is proving very popular due to its simple design and robust hardware. It continues to gain in popularity and has been adopted by many municipalities throughout Southern Africa, as well as numerous large industrial and mining companies.

What is WRP’s view of the importance of social issues in the waterloss sector? WRP employs approximately 50 personnel in its Gauteng and Western Cape offices, most of whom have been with the company for 10 years or more. The company created a section within its Water Loss Division to concentrate on the social issues and community awareness and education, which all form a major component of any water-lossreduction project undertaken by WRP. It is our belief that even the best technical water-loss intervention will ultimately fail if the social and community awareness issues are not addressed. In the recent PPP undertaken by WRP for the German government and First National Bank of Botswana in Gaborone, for example, the budget was split evenly between the technical and social issues, which led to a highly successful project.

Save energy,

Shor t-term crisis management in the face of South Africa’s water crisis is necessar y, and considerable investment has been made to upgrade ageing infrastructure to prevent water loss. A long-term, sustainable solution requires innovate thinking to achieve holistic resource management. BY BEATRIX KNOPJES

PPROXIMATELY 37% OF South Africa's drinkable water is lost ever y year. Minister of Water Affairs & Sanitation Nomvula Mokonyane told CNBC Africa's Gugulethu Cele in an interview at the World Economic Forum in Davos, “Ageing infrastructure, a lack of proper water management and the intelligent use of technology mean that South Africa is still dealing with water treatment in an archaic manner; we have huge water treatment plants, even though the world is going smaller to be more efficient. The DWS is looking at innovative solutions.

For example, the issue of desalination is no longer something that is up for discussion, it is something that has become a reality.” To this end, the Department of Water & Sanitation (DWS) and the Department of Energy (DoE) are coordinating on a number of initiatives and projects to deliver on sustainable energy and water services for the country. The two departments have collaborated and developed a standard guidance note regarding water availability and water-use licensing for the coal-baseload Independent Power Producer Procurement Programme.

Mokonyane stated, “Part of the reason why we support the interventions, in terms of renewable energy, is to move away from a high dependence on electricity that consumes large amounts of drinkable water that could be supplied for domestic use. Why we support nuclear solutions – among other things – is to relieve a water-scarce country from being highly dependent on the supply of water for electricity.” She stresses the relationship between water and energy in South Africa as codependent: “Without the availability of energy, we will also battle to pump through water to communities and business. Therefore, the collaboration with the DoE is quite important in terms of hydro systems.” The minister also emphasises the importance of innovation, research and development, and collaboration between departments to create holistic, sustainable solutions for better resource management. “That

is what we are doing with the departments of trade and industry, agriculture, and science and technology.”

Sustainable hydropower The DWS and DoE have also commenced with the development of the enabling hydropower policy document. The overall objective of the document is to provide policy position for the DWS on the establishment and development of hydropower through existing infrastructure. Sustainability consultant Karin Ireton, speaking at the 2016 Africa Energy Indaba, said that hydropower has the capability for longevity with relatively low maintenance. “It is necessary to drive a different line of thinking to unlock the potential of hydropower,” she says. “Water used for hydropower is ‘borrowed’, rather than consumed, as is the case in traditional coal-fired power stations,” explains Ireton. This allows water that would be used in power generation to be allocated to other uses. However, there are a range of issues when using the kinetic flow of water to generate energy. This is because water levels fluctuate, making the energy generated inconsistent. Ireton explained that the way around this is to “link hydropower into a hybrid system that incorporates other forms of power generation, such as solar.” One of the prohibitive factors in hydropower is the cost of building dams – not only financial but also environmental and social. “More and more, hydropower is The Grand Inga DAM Hydropower Project along the Congo River has the potential to generate approximately 40 000 MW – enough to power half of Africa

being used in the run of a river or retrofitting on to existing dams. While there has traditionally been an appetite for big dams and hydropower projects, the viability of introducing hydropower on a micro scale is fast gaining momentum, especially at municipal level.” Hydropower is not a new technology by any means – it has been implemented in varying scales for the past century. Breakthrough technology is not necessary here, according to Ireton, but what is rather needed is modern thinking in terms of how challenges can be met sustainably. She goes on to say that implementing micro-scale hydropower schemes does not need a highly skilled labour force. “There have been projects successfully implemented in Zimbabwe, using an unskilled labour force – many of whom have never before had jobs at all. This means that implementing hydropower on a micro scale includes a social aspect in the form of job creation.”

Working together As a long-term intervention by the DWS to support sustainable power supply in South Africa, the policy will look at infrastructure within the water resources. In addition, the overall objective of the DWS is to encourage energy efficiency initiatives in the water and sanitation sector. Julie Wells, communications manager, National Cleaner Production Centre, says: “By looking at the consumption of energy in water processing, and optimising the technology in those processes, energy is saved and water wastage is reduced.” Wells states that the water efficiencies gained are not as significant as the energy savings. However, by saving energy and reducing

the demand for coal-fired power stations – a large consumer of water – water is indirectly saved as well. The relationship between resources should not be overlooked. As Wells explains, “The methodologies and ideologies involved in saving energy and water are similar.” The cogeneration programme has also been implemented, which works to ensure the simultaneous generation of electricity and useful thermal energy from a common fuel or energy source. Eskom has collaborated with the DWS in developing pump storage schemes for peak power generation. According to a release issued by the DWS, it and other water supply systems operators require energy for their operations, especially for pumping water to various demand centres. The coordination of resources by the DWS and DoE is sure to harness the water and energy supply to the country. Wells explains, “On the technological front, there is great potential for optimising energy in the pumping and purification of water.” She adds that additional to optimising resource efficiencies, industries should be motivated towards cleaner production, as they are, in part, responsible for the contamination of water and the overall drop in water quality, which adversely affects water supply.

Conclusion The current water crisis in South Africa, in the wake of unstable energy supplies, highlights the importance of collaborative resource management. The two resources are interlinked and are fundamental to stable economic growth. Both need to be managed prudently to achieve longterm sustainability.

The value of knowledge goes beyond power Approximately 37% of South Africa’s potable water is lost ever y year. With the severe drought caused by the El Niño weather phenomenon, government cannot afford to tolerate such losses and is in search of innovative solutions to help bridge this water gap. BY LIESL FRANKSON

URING HER VISIT to the World Economic Forum in Davos, Switzerland, earlier this year, Minister of Water & Sanitation Nomvula Mokonyane addressed the issue of the country’s water losses in an interview with CNBC Africa's Gugulethu Cele. “Part of our presence here at the world economic forum has to do with investment in water infrastructure, because the loss of that volume [37%] of water has to do with aged infrastructure and backward systems of water management,” stated the minister. Mokonyane said that the country is still dealing with water treatment in a very archaic manner rather than being hightech and smart. When one considers the entire water system, there are numerous

elements involved and each of these elements has a role to play in responding to this task. “It is impor tant for municipalities to understand exactly where their problems are in the network in order to address the issue as quickly as possible,” says Willem Wegelin, director, WRP Consulting Engineers. “Half of our municipalities aren’t sure what their water losses are and, in a drought-stricken countr y, this is a little scar y; but, the question is: where do you start?” According to Wegelin, there are a few simple things municipalities can do before they apply expensive technological solutions to tr y to solve the waterloss problem. “Municipalities can start to curb water losses by metering their input volumes, metering consumers (especially those living in built-up towns and cities), fixing the leaks and keeping a regular schedule of maintenance on pipes, pumps and valves,” he explains. In a time when we cannot afford to lose any more water or money, pipes, pumps and valves that are easy to install, easily maintained and inexpensive have the most value for our municipalities.

“Two major causes of water loss are corrosion and poor jointing. For this reason, old steel or asbestos pipes around the world are being replaced with plastic pipes, because they do not rust and the joints are leak-proof, if done correctly. As the voice

The cost-effective conduit According to Jan Venter, chairman, Southern African Plastic Pipe Manufacturer’s Association (SAPPMA), plastic piping systems have been proven, worldwide, as the most cost-effective way of ensuring long-term, leakfree transportation of water and sewage.

of the plastic pipes industry, we feel it’s our responsibility to not only keep pushing for the country’s water infrastructure to be upgraded, but also to educate consumers, engineers and other decision-makers about the benefits of using plastic pipes over other materials,” Venter explains. There are many advantages for the engineer and the municipality with plastic pipe systems. The three main benefits include: ease of transport, handling and installation; leak-proof and maintenance-free conveyance systems; and energy-efficient fluids conveyance over the entire lifetime, due to the flow characteristics not materially changing.

Water savings at the installation phase When it comes to getting the most out of your pipes, pumps and valves, and stopping water loss, Wegelin believes the installation is critical. “What we’ve seen is that, if you don’t install something correctly, it will leak. In the case of pipe installation, your construction methods need to be sound – you need the correct bedding layers, etc., to ensure that, as you build on top of the pipes, they will not crack.” Certain technological advancements in pipe laying and the pipe material used may help to combat some of the effects of the installation process. According to Tony Dean, managing director, Rare Plastics Division at the Rare Group, the company manufactures a specialised co-extruded, three-layered pipe that has high resistance to crack propagation (specifically for trenchless installation). “In conjunction with our technology partner, Borealis, we have produced a water

IMIESA March 2016

pipe specifically for alternative installation techniques (AIT). Trenchless technology and unselected embedment construction methods demand a pipe capable of being installed where any damage caused by the aggressive conditions will not result in failure of the pipe. The outer and inner layers of the pipe are made up of PE100-RC polymer, with a PE100 core. PE100-RC is a specifically developed, advanced polymer that resists the effects of notches, scores, scratches, grooves and point loads that may result from the trenchless installation technique used or installation without selected or imported bedding and embedding material.

The right pumps, for the right application Pumps and valves that are low-maintenance and adaptable are highly sought after by municipalities and, according to Hendrik Enslin, manager: Water and Wastewater Projects and Applications, KSB, the company has a wide range of fit-for-purpose pumps in a variety of different materials to suit conditions. The company’s headline sewer range includes Sewatec purpose-built sewerage and wastewater pumps with run-dry capability and a double mechanical sealed system for reliable, long-duration pumping without maintenance. The KRT range of wet- and dry-application pumps consists of sophisticated pumps that are designed to work in submersible, semi-submersible and dry conditions, allowing adaptability in varying applications. “They are designed for sludge and water applications, with non-clogging impellers,” he explains. Enslin notes that all KSB’s pumps can be manufactured using a variety of materials and have different impellers to suit any application. In addition, the company has a vast range of related pumps and products that have various applications and that may be suitable for sewer applications as well.

“To discuss the entire range is difficult, because of the huge range that we carr y locally and abroad at our global manufacturing facilities. Suffice it to say, we have the right pump for almost ever y application and, as a result, municipalities, water authorities and engineers can call upon our expertise to assist in the refurbishment of old plants, the maintenance and

MULTIPURPOSE PUMPS

Imagine the long-term multiplier value of knowing the difference between a single-use borehole pump – equipped to reliably pump a sufficient volume of water to irrigate and support a small subsistence farmer’s crops, workers and family, and affordable enough for a small municipality to supply 10 farms – compared to a multipurpose pump, which is equipped and powerful enough to pump high volumes of borehole water whilst also able to boost flow pressures in a distribution network. Significantly more costly than the single-purpose pump, at six times the price, a multipurpose pump has the potential to supply not only the 10 farmers, but six additional community stands, the municipal offices and the local school. The additional pipe network and to-thepoint plumbing required for this significantly more valuable output matches the cost of the 10 singlepurpose pumps.

replacement of existing pumps, as well as the design of new pumping systems that will be capable of meeting future demands,” he adds.

Reliable technical support Although cost-effectiveness is a major factor, it should not be the only factor when it comes to choosing suppliers. Nowadays, technical advice and support are equally as critical as choosing the right system and design in the first place. “In recent times, municipalities and water authorities across Africa have moved away from a purely cost-based procurement model to rather focusing on procuring systems and expertise from local manufacturers with a long and reliable track record of quality products backed by efficient and reliable service and support,” Enslin comments. Wegelin agrees, “Spare parts and technical support need to be readily available. We can’t afford to wait for weeks for a spare part, because water is being lost in that time. At times, suppliers and manufacturers will come to the country with a big fuss and, a few years down the line, they disappear, leaving municipalities with the task of having to start the process all over again.”

A solution Amid severe shor tages, there is a growing demand for water in the KwaZulu-Natal coastal metropolitan area. As a result, the argument for constructing desalination plants is becoming increasingly convincing.

worth its salt?

BY KEVIN MEIER1, MIKE KILLICK 2, GRAHAM ENGLISH2 & MIKE SHAND2

HE WATER REQUIREMENTS of the KwaZulu-Natal coastal metropolitan areas are growing rapidly. Approximately 92% (1 072 Mℓ/d) of the water provided by Umgeni Water (UW) to the six water services authorities it supplies is sourced from the Mgeni System. This system consists of an extensive network of pipelines, aqueducts, water treatment works and reservoirs, supplied from the Midmar, Albert Falls, Nagle and Inanda dams in the Mgeni System, as well as from Hazelmere Dam on the Mdloti River. The Mooi-Mgeni River Transfer Scheme from Smithfield Dam supplements the supply of water in the upper Mgeni River. Conventional water resource development options, particularly surface water schemes, are becoming less viable. The most feasible sites for new dams or abstraction works have, in some areas, already been developed. This, coupled with the impacts of climate change on rainfall and runoff, as well the need to provide for downstream environmental water requirements, adversely impacts on the sustainable yield that can

be developed from surface water schemes. Alternative sources of bulk water supply are, therefore, being investigated by the Department of Water & Sanitation and water service providers. One such alternative is that of seawater desalination.

Due diligence phase As a precursor to the detailed feasibility study (DFS), a due diligence assessment was undertaken for each site to confirm its suitability for a 150 Mℓ/d desalination plant. Both sites were inspected and initial assessments

undertaken in respect of seawater quality, geotechnical conditions, required infrastructure, pipeline alignments and pump station locations, marine biology, botanical considerations, and estuarine impacts. The key outcome of the due diligence assessment was a recommendation that, due to the anticipated adverse impacts on the Mdloti River estuary, an alternative site immediately north at Tongaat was recommended

as a preferred alternative. A DFS and preliminary design were, thereafter, undertaken at both the Lovu and Tongaat sites.

controlled conditions. The RO process has high energy demands, but does offer very viable means of utilising surplus energy from the process to reduce the energy demand from the national grid. RO removes dissolved salts from saline water by a process similar to filtration and, as such, the membranes are susceptible to fouling by colloids, organics, iron and manganese. Consequently, extensive pretreatment is required to reduce membrane fouling and maximise membrane life. Typically, seawater RO plants operate at a recovery rate of up to 50% (i.e. the potable product water amounts to about half of the volume of seawater intake). Although pressurising the feedwater requires substantial energy, RO has a lower energy requirement (4–5 kWh per m3) than distillation processes.

conventional determinants, while biological classes include bacteria and algae. Following the seawater quality monitoring, it was confirmed that the quality of water would be suitable for desalination at both sites, and that the plant designs could be similar. A seasonal occurrence of micro algae was found to be of particular concern in terms of potential membrane fouling. A pretreatment pilot plant is currently being implemented by UW to assess the effectiveness of various pretreatment filters in the removal of the algae upstream of the RO membranes.

common operational issue encountered in seawater RO plants is the formation of deposits (fouling) on the sur face of the pretreatment filters and on the RO membranes themselves. The broad “classes” of water quality parameters assessed included nutrients, metals, anions/cations, hydrocarbons and

Boron concentrations are only of concern where desalinated seawater is to be used for irrigation. Although not the intended use by UW, this can have implications where water is ultimately reused for watering golf courses, school fields and public open spaces, for example, and grass die-off or stunted growth could eventually result. As water from desalination plants is characteristically low in mineral content, hardness, alkalinity and pH, it must be conditioned (post-treated) prior to final distribution and use. Post-treatment of fresh water produced by desalination has two key components: these are mineral addition (lime and carbon dioxide or lime contactor), in order to safeguard the integrity of the water distribution

system, and disinfection to protect public health (chlorination or chloramination). The product waste streams from a desalination plant include concentrate (brine) as well as small concentrations of spent backwash water from the pretreatment system, spent membrane cleaning solution, and flush water. Energy used for seawater desalination contributes 50% to 70% of the total plant annual operation and maintenance costs, and 25% to 35% of the total costs of fresh water production. Consequently, reuse of energy is very beneficial and cost-effective, and is achieved through the use of energy recovery devices.

Marine infrastructure The use of two intake pipelines at Lovu is a result of a design balance between pipe diameter, availability, and constructability. Both sites will make use of an open-water offshore

intake with primar y (course) screens having bar spacings at about 150 mm centres. These types of intakes are more suited to larger-scale desalination plants, such as the two proposed. Alternative intake arrangements were considered, such as offshore subsur face intakes and onshore beach wells. However, the scale of the intake volumes required at both sites is such that these alternatives prove unfavourable from a footprint size and environmental impact perspective. The Lovu Scheme shows the layout of the proposed scheme and the three options considered for the terrestrial pipeline alignments between the seawater intake pump station (at the beach) and the desalination plant site (3 km away), namely: • Option A would comprise two parallel 1 800 mm HDPE pipelines (one seawater, one brine) laid in the northern floodplain of the Lovu River estuar y, by conventional pipe trenching, with a specially constructed pipe bridge for the river crossing. • Option B involves two 2 000 mm diameter parallel 1 100 m long microtunnels (one seawater, one brine) to the southern bank of the Lovu River. From there, two 1 800 mm diameter HDPE pipelines would be laid by conventional pipe trenching to the desalination plant. • Option C comprises two 2 000 mm diameter parallel 650 m long microtunnels (one seawater, one brine) to the northern bank of the Lovu River estuar y, from where two parallel 1 800 mm HDPE pipelines would be IMIESA March 2016

conventionally laid, crossing the river by means of a specially constructed pipe bridge. Having considered the geotechnical, engineering, environmental and cost implications, Option A was found to be preferable for the land-based delivery, and brine return-flow pipelines for the Lovu scheme. At Tongaat, the intake and outfall shaft would be located within the desalination plant site and, as such, the land-based sea intake pipeline and brine return pipeline connecting the shaft to the adjacent desalination plant would be very short.

Integration of potable water into existing systems The Lovu desalination plant would supply water to UW’s South Coast Regional Bulk Supply System and would also supply some of the areas served by the SCA pipeline (southern areas of Durban) that are currently supplied by the Wiggins water treatment plant. The desalination plant would be constructed in two 75 Mℓ/d phases with the timing of the second phase dependent on future water demand growth. At Tongaat, water would initially be supplied to eThekwini Metropolitan Municipality’s Northern Aqueduct via Waterloo Reservoir, from where the water would be pumped into the Northern Aqueduct (northern areas of Durban). As the demand of UW’s North Coast Supply System increases and exceeds the supply from the raised Hazelmere Dam and from the Lower Thukela Bulk Water Supply Scheme, the supply to the North Coast from the desalination plant would be increased by delivering water to the Avondale Reservoir (Ballito). The

same two-phased approach to the RO components would be adopted as at Lovu.

The Spring Grove Dam

Bulk power supply

geotechnical conditions at Tongaat could render tunnelling a non-feasible option • the risk at Lovu of incorrect installation of marine pipelines due to difficulties in crossing the sur f zone • the possibility that the bulk power supply to the desalination plant would not be implemented on time • the risk that the EIA record of decision is not in favour of desalination. However, none of the above are considered likely, and mitigation measures and controls are possible for each of them.

Each desalination plant would require between 24 MW and 32 MW of power. The power supply to the Lovu desalination plant and its seawater pump station would be from the nearest 132 kV point of supply, which is the Kingsburg Major Substation in Illovo, about 2.5 km from the proposed desalination plant site. The supply to the seawater pump station at the beach would be via an 11 kV overhead line from the desalination plant site. At Tongaat, the nearest 132 kV point of supply for the desalination plant and the seawater pump station (also located at the desalination site) is the La Mercy Major Substation on the western side of King Shaka International Airport. Timeous communication with eThekwini Electricity will be important, as the substation is located on the western side of the airport, and obtaining way leaves and a servitude for the 132 kV transmission line to the proposed site could be problematic.

Risk analysis Potential risks that could impact on the proposed desalination plants were identified. The impacts, consequences and probability of each were identified, as well as the control measures that would be possible to mitigate the impacts. The scale used for each of the variables and indicators used is shown in Table 1. Seventy-four risks were identified, scored and ranked and only the following four were considered to be potential “fatal flaws”: • the possibility that the eventual marine

Financial assessment Preliminar y estimates of the capital and operating costs of the Lovu and Tongaat desalination plants are given in Table 2. While the Lovu desalination plant has a higher offshore cost component, the Tongaat Plant has slightly higher overall capital costs, primarily due to the lengthy potable water infrastructure required to integrate the desalinated water into the existing potable water supply system. The Lovu Desalination Plant has a higher operating cost due to the higher energy cost required to pump the desalinated water into the existing potable water supply systems. 1

Saving water with pervious concrete With the dramatic rise in urbanisation and the drop in mean annual rainfall, efficient stormwater management to reduce the risk of flash flooding and sustain natural water cycles is a growing challenge.

HE PREVAILING DROUGHT in South Africa draws into sharp focus the necessity of maintaining the quality of water in the water system. Pervious concrete, such as Lafarge’s Hydromedia, used in urban environments, is instrumental in recharging groundwater while reducing stormwater run-off, and can form part of a cost-effective sustainable urban drainage system (SUDS). Lafarge’s research has achieved a technological breakthrough with Hydromedia, a fast-draining, porous concrete. It provides rapid stormwater removal from streets, parking sur faces, driveways and walkways. This unique product outper forms traditional permeable pavements, minimising the cost and long-term maintenance for local authorities and developers of stormwater management infrastructure. It allows for more efficient land use by eliminating the need for retention ponds, catchment basins and other stormwater management devices. In addition, the product acts as a filter, mitigating contamination of groundwater by sur face pollutants, thus preser ving the quality of the water cycle as a whole. It can also be used as a means of rainwater har vesting. Per vious concrete has an additional safety element in urban environments. “Our new per vious concrete, Hydromedia, facilitates the flow of rainwater into the subsoil and reduces the risk of flooding in parking lots, driveways and sports grounds. Additionally, it is easier to implement and stronger than ordinar y per vious concrete,” explains Shane Campbell, product manager, Lafarge. Thanks to its ver y high permeability and drainage capacity, Hydromedia absorbs

rainwater and facilitates its natural run-off into the ground. Campbell adds, “It also avoids saturation of the stormwater treatment network, reducing the risk of flooding. Finally, water no longer accumulates on roads and paths. This means fewer puddles and safer roads, pathways and parking lots for users.” Due to its viscous yet fluid formulation, Hydromedia is easier to place than existing per vious concretes. This cutting-edge technology also gives it greater robustness and better long-term resistance.

Construction chemical R&D centre in SA

LEADING CONSTRUCTION chemicals producer plans to use South Africa as the springboard for increased penetration into the African continent through the establishment of a new research and development (R&D) facility at its head offices in Jet Park in early 2016. This announcement was made by the global CEO of the Chryso Group, Thierry Bernard, during a recent visit to South Africa, where he met with the Chryso executive vice-president, Norman Seymore, who is also CEO of Chryso Southern Africa.

Bernard says that, although the company is an international company doing business in more than 70 countries with subsidiaries in 20, it regards Africa as one of its most important markets. “About 25% of our total sales are to African countries, with South Africa and Morocco by far our major markets on the continent. We have made substantial capital investments in our operations in South Africa in recent years and, in future, we want to use South Africa to drive further investments in Africa, some of which are imminent.

Thierry Bernard, global CEO of Chryso, based in France, announced the opening of a new R&D Centre at the Chryso head offices in Jet Park

Products for the African market “We realise that our South African operations need to maintain and

improve the service they offer to customers. There has been a growing need to develop specific products for the African market, and for more efficient and prompt testing services for our customers in sub-Saharan Africa. The new R&D facility in Jet Park will be equipped with the most modern, high-tech facilities and will include, to a significant extent, the R&D equipment we operate in France, Turkey and India,” Bernard said. “The construction industry today demands innovation and new solutions to 21st century building philosophies and techniques – and that is an important motivation for opening the new South African R&D Centre. Local demand in the field of construction chemicals has to be catered for – from

the industry's doorstep, not from another continent,” he added. “This will be an industry-first in Southern Africa in the services it offers.”

Expanding even further Bernard said the company planned to expand its African presence even further than the recent opening of production facilities in both Kenya and Algeria. "Future African penetration will be either through acquisitions or greenfield developments. There are three areas, in particular, that we are currently targeting. The first is Egypt. Then, there is West Africa, particularly the Francophone countries such as the Ivory Coast and Senegal, where we are already doing business. Finally, there is Nigeria, which has a strong economy and substantial business prospects. Chryso’s entry into these countries will be carried out in phases over the next two to three years."

Global future expansion plans for the company include increasing its operations in Sweden, where a production facility to serve the Scandinavian market is on the cards, as well as in a Middle East Gulf Cooperation Council country, where the establishment of the company’s operations has virtually been finalised, with an announcement in this regard due before the end of the year. “We also need to be more active in SouthEast Asia, so that's another region where we are planning to increase our presence.” He said the company’s expansion globally, and in Africa's emerging markets, hinged on being flexible and selective. “We are not 'putting all our eggs in one basket'. The economies of African countries, in particular, are volatile and subject to unexpected slowdowns, so expansion plans have to be very selective and avoid relying too much on one particular country,” Bernard added.

A formula for African growth Africa is a diverse continent of 54 countries with over 2 000 languages and an array of landscapes. In business terms, the many challenges facing Africa make it a continent ripe for development. For a globally active specialty chemicals company, it represents huge business potential.

FRICA IS OFTEN CALLED the forgotten continent, yet Sika has a long history of major investments in this emerging market. Sika’s area manager: Africa, Jean de Martres, tells IMIESA why. “Africa is a vast geographical continent with abundant natural resources and huge growth potential. The company recognises this and wants to be part of it. Today, there are some 1.1 billion people living in Africa, and this number is expected to double by 2050, making this the first time ever that growth of such magnitude has been seen in the space of one generation,” explains De Martres. “This is triggering a gigantic need for infrastructure and housing both in megacities and in the countryside. The construction sector is reporting high growth rates in most markets. Chinese contractors, in particular, have penetrated the market over the last 10 years, accounting for over 60% of Africa‘s total volume of activity,” he continues.

locally in several countries, the company took over the expor t approach adopted by many of its European organisations. The company’s new strategy for Africa has changed this model and focuses on what those countries and customers expect: a local manufacturing presence with local raw materials and local technical suppor t and training. Markets and countries were identified where the company can expand its footprint, quickly and ef ficiently. In the past three years, Sika has doubled its production capacities in Africa, with seven new factories coming on stream in Ivor y Coast, Nigeria, Kenya, Angola, South Africa, Mozambique and the island of Réunion. The company’s local operations now comprise 16 countr y organisations. “To ensure economic growth, Africa needs roads, railway lines, ports, water and energy supplies. This spells fantastic potential for the construction sector: investments totalling $380 billion are to be channelled into the transport and energy infrastructure by 2040 alone,” De Martres explains.

"To ensure economic growth, Africa needs roads, railway lines, ports, water and energy supplies."

Positioned for growth Sika’s first business ventures in Africa date back to 1947. Operating

“Of course, project financing is frequently uncertain, with the exception of the approach taken by the Chinese. These companies usually put together a deal package that includes the securing of financing against the allocation of natural resources. We have the know-how and superlative brand recognition to enhance our presence in these markets,” he adds.

Jean de Martres, area manager: Africa, Sika

Rapidly developing supply chains and operations In line with the Sika Strategy 2018, the company is aiming to double sales over the next five years, maintaining its current excellent level of profitability. The main focus in 2015 and 2016 will be on ensuring the newly established companies’ sales penetration levels as well as pursuing the development of West, East and Central Africa to cover the main markets. “We are already very well positioned in Southern and North Africa,” he notes. According to De Martres, future boom markets in Africa include new

our local organisations a lot of freedom, giving them a sense of ownership and entrepreneurial spirit. This requires employees to assume responsibilities, take a businessled approach, embrace empowerment and seize the chance to grow in our organisations. The identification, training and coaching of such employees are among our critical success factors in Africa.”

giants such as Nigeria and Ethiopia, the only two African countries projected to exceed 300 million inhabitants by 2030. Mozambique, Tanzania, Algeria, Angola, Ivory Coast and other medium-sized countries will also benefit from their natural resources and continue to grow, despite falling oil prices. A huge market with a population of more than 80 million, Egypt is currently facing security issues and suffering from a lack of financing resources.

Overcoming obstacles De Martres says the company sets itself apart from the foreign competition in terms of its business model. While many major European players still import their products into Africa, Sika conducts its business locally. “This means we are present

IMIESA March 2016

in the respective countr y with a local subsidiary and, even more importantly, we produce and sell locally to ensure our supply-chain availability. “Second, we not only want to sell products, we also want to be a real solutions provider for our customers, by offering technical assistance and training as well. This is crucial for Sika’s development in Africa and a clear differentiating factor among major foreign competitors. In terms of local competition, the market is still very fragmented. There are various small players on the ground, but they do not significantly affect our position,” he notes. One of the company’s main challenges is human capital, especially finding the right employees who share the company’s values and principles and come with a solid educational and professional background. “We do not conduct our business topdown, in a centralised way, but allow

Lauca Dam, in Angola, is part of the largest hydropower facility in the country and is scheduled for completion in 2017, at a cost of around $4 billion. The dam will be an impressive 132 m high and 1 100 m long. Sika is providing mortar, concrete admixtures, sealants and coatings. Another landmark project for the company involves two related transport projects in Mozambique’s capital, Maputo: the Catembe Bridge (628 m long and 137 m high) and the 74 km ring road. Together, estimated to cost around $1 billion, these two projects will serve to improve the traffic situation in the capital. Here, too, the company is providing mortars, concrete admixtures, sealants and coatings.

Looking ahead One of the Sika Strategy 2018 objectives is the accelerated build-up of the organisation in emerging markets and the expansion of the supply chain footprint in order to increase sales generated in emerging markets, from the present 37% of total sales to 42% to 45% by 2018. Africa is one of the focal regions for the company. In the first six months of 2015, Sika’s sales in the region were up 18%.

Specifying for

failure avoidance

Building materials producer associations are calling for tighter specifications to be applied when awarding tenders to ensure that the principles of quality are applied from the very beginning.

N LIGHT OF GOVERNMENT’S rising repair bill, the Aggregate and Sand Producers Association of Southern Africa (Aspasa) and the Southern Africa Readymix Association (Sarma), whose materials constitute the vast majority of materials on any standard construction site, suggest that the most likely cause of structure failures is the result of the use of inferior or non-suitable materials.

“No matter how good the design is, or how skilled the workmen are, the structure will fail ever y time if unsuitable materials are used,” says Nico Pienaar, director on both associations’ boards. While some professional bodies within the industr y have begun questioning government’s tender process and the awarding of tenders to inexperienced (cheap) contractors, he

Nico Pienaar, director, Aspasa and Sarma

cautions that attention also needs to be given to ensuring quality building materials are used.

Low entry barriers Pienaar says, “In South Africa, it is a fact that anybody can buy a mixer truck and start producing ‘readymix concrete’. Likewise, sand and stone can be excavated from any vacant lot and be labelled as building sand and aggregates. But, the reality is that this does not constitute proper building materials. “Industr y associations such as ours were established specifically to bring regulation to our industries and formalise the industry to the extent that members can be relied upon to produce products that conform to the standards required by their customers. “If procurement is done from the informal or unregistered end of the industry, there are no checks and balances and no real way of knowing what you are buying. Did the so-called readymix supplier use inferior-quality cement, was batching done correctly, were the desired mixes adhered to or did the supplier use aggregates with the right mineral composition?”

A quick fix Pienaar speculates that, in the vast majority of cases, these informal, unregistered suppliers will not be able to provide evidential information about the quality of their products in the event of a failure. After all, if they are not measured by any formal standards and their processes are subjected to no form of review, then how can they possibly supply useful evidence to prove the materials they supplied were up to standard? “It is, therefore, imperative that government and the formal construction industry become serious about quality and begin to ensure that materials are procured only from professional suppliers who are registered with the relevant industry association and who are regularly measured against strict standards and criteria, as is the case with both Sarma and Aspasa members. “It is our belief that government can dramatically reduce failures and subsequent expenses resulting from rebuilds simply by procuring building materials from compliant and registered companies,” concludes Pienaar.

CONSTRUCTION VEHICLES, EQUIPMENT & LOGISTICS

Raising the roof at Bauma 2016 The demand for luffingjib tower cranes is rising in many parts of the world. As such, some of the most successful models will be on show at the upcoming Bauma trade fair, in the German city of Munich from 11 to 17 April.

OWER CRANE manufacturer Linden Comansa will showcase a luffing-jib crane and two with a flat-top design at the stand the manufacturer shares with its partner BKL Baukran Logistik GmbH, one of Europe’s largest crane rental, sales and services companies. One of the manufacturer’s goals at Bauma will be to continue promoting its extensive range of luffers, which consists of 12 different models, with maximum load capacities between 8 tonnes and 30 tonnes. To this end, the brand will exhibit a LCL280 luffing-jib crane with maximum

load of 18 tonnes, a model which also has 12 tonne and 24 tonne versions. The LCL280 is one of the manufacturer’s most popular luffing-jib models, especially in the UK, areas of the Persian Gulf, and Southeast Asia. In addition, the LCL series of luffingjib cranes, to which the exhibited model belongs, has recently been reviewed and features many improvements.

Large capacity for infrastructure projects The 21LC750 flat-top crane has a large capacity (24, 36 or 48 tonnes) and is suitable for work in the industrial, infrastructure and mining fields. Launched in 2009, this crane has been recently revised and optimised, and returns to Bauma after last being exhibited in 2010. All its features (ease of erection, high-speed hoist engines, reliability, etc.) make this crane a favourite of Linden Comansa customers the world over. In fact, the 21LC750 has been sold in all continents and regions. The third crane the brand will be exhibiting is the flat-top model 11LC160, with a maximum load of 8 tonnes. The crane is part to the LC1100 series, which has been reviewed by the manufacturer’s R&D Department and includes

numerous improvements, such as the frequency control on the slewing movement or the space optimisation on the slewing part. This crane is designed to offer better performance in the construction of small-sized industrial and commercial projects, and is especially successful in Central European countries, such as Germany, Switzerland and Austria.

Strengthening relationships The three cranes to be exhibited are just the tip of the iceberg and attendees of the Bauma show can expect to learn more about the new 21LC450 flat-top crane, the redesign of the cabins, the improvements in the LC2100 series and the launch of a new luffing-jib crane taking place in the year. According to Martín Echevarría, sales director, Linden Comansa, “Bauma is the perfect platform to make new contacts, find new distributors and show our products and services to the market. In addition, the fair also helps us to invite our clients and friends to further strengthen our relationships with them.”

Empowering young minds Thirty-three BSc Hons Mining Engineering students from the University of the Witwatersrand got a first-hand look at the operations of Atlas Copco, one of the country’s leading sustainable productivity solution providers.

OUTH AFRICA’S MINING, industrial, business and commercial future lies firmly in the hands of our youth and how aptly they are able to apply their knowledge when they embark on their working careers,” says Kgothatso Ntsie, corporate communications manager, Atlas Copco South Africa. Ntsie says the company decided to extend an invitation to the students to tour the Jet Park-based South African headquarters to gain insight into the multitiered business relationships between customers and the supplier. “This relationship goes far beyond simply the sale of equipment and includes expert advice, after-sales service, and more. It is essential that students, irrespective of their field of study, gain a practical taste of the

working world to assist them in orienting theory within the perspective of real-life situations,” Ntsie explains.

ABOVE RIGHT Wits mining engineering students gained a practical taste of the working world during their visit to Atlas Copco Mining & Rock Excavation

The day’s proceedings kicked off with a presentation from Vince Tyler, business line manager: Underground Rock Equipment, who gave an overview of the company’s expansive range of underground as well as opencast mining equipment and consumables. Tyler shared with the students that the supply of world-class quality equipment solutions is equally as important as the development of long-term customer relationships. “Every time we supply equipment, we enter into a partnership with our customer so that we get to know their specific requirements to ensure we can offer the best solution to meet not only immediate but also future needs. We support our customer over the equipment’s life-time.” Following Tyler’s Q&A session that prompted some excellent questions and yielded interesting discussions, students were taken on a tour through the Distribution Centre and workshop.

A valuable experience Wits students Siphiwe Nkosi and Steven Valoi shared their thoughts on their experience and agreed that the day was extremely valuable. Nkosi was blown away by the immaculate state of the workshop and says that a clean, structured environment provides a good workspace and conveys the message that

the team is dedicated, committed and professional, with the ability to not only provide the right quality products but also offer the necessary back-up and maintenance support to keep customer downtime to an absolute minimum. While Valoi’s main focus lies in underground technology, he says Tyler gave him a good perspective on open-cast mining. “What really impressed me was that, while most companies are shying away from hard rock mining due to the extreme depths that are both difficult and extremely expensive to reach, Atlas Copco’s focus is here, finding a workable solution for the local mining industry, which is in dire need of assistance. Atlas is prepared to share its know-how without necessarily selling any equipment. That is true commitment to South Africa and the mining industry!” Nkosi and Valoi felt that the company went out of its way to give the students a memorable experience, which made them all feel very special. “On behalf of all the students, we extend a sincere thank you to Atlas Copco for adding so much value and for the exceptional experience that we will be able to apply in our future careers.”

a customer needs only basic service, the Condition and Contact programmes are suitable.

A variety of consultation services Konecranes offers a variety of consultation services that can provide a deeper analysis of a customer's lifting equipment and help identify improvement opportunities. Trained technicians can provide equipment analyses beyond simple visual inspection, such as: • RopeQ magnetic rope inspection, which analyses the condition of internal wires, strands and the wire rope core • RailQ crane runway survey, which uses a remotely operated robot to analyse the alignment of the crane rails • CraneQ crane geometric survey, which provides an accurate geometric analysis of the crane. This consultative approach can help guide customer decisionmaking. Konecranes takes time to meet with its customers to provide recommendations based on industry-leading expertise. “We don’t just drop off a report on our way out, but rather take the time to share our findings and discuss how each action impacts the operations of our customer. With our industry-leading technology and non-destructive testing, we can uncover latent or hidden defects with minimum disruption,” says John MacDonald, service and marketing manager, Konecranes.

COMPANY NEWS

A name celebrating Afrika

NGINEERING AND environmental consulting centenarian Jeffares & Green (J&G) will be changing its name and renewing its brand to better reflect its goals and strategies. Throughout its existence, J&G has evolved, keeping pace with fluctuations in demand, the industry and customer requirements. To maintain momentum for continuous development, the bold decision was made to rename and rebrand the company in order to better align the brand with its areas of operation – the African continent – and highlight its proudly South African status. According to Charmagne Denny, marketing and communications manager, J&G, “The brand development process started with the appointment of brand specialists. After much hard work, research and an inclusive staff voting process, JG Afrika was chosen.” This name was designed to represent the company’s identity to the world, while maintaining its African roots. “The inclusion

of ‘JG’ symbolises the company’s acknowledgement of and appreciation for its history, while ‘Afrika’ denotes its independence, its love for the continent, and is a nod to the African way of spelling Africa,” says Denny. The new corporate identity (CI) will be launched in April 2016. “The J&G name has served us well; however, the time has come to look to the future and align our CI with our diverse, modern and highly skilled workforce,” says Paul Olivier, managing director, J&G. “We sincerely enjoyed the process of evaluating naming options and involving our valued staff, upon whom our success is built.” He concludes, “We assure the industry that we remain the same professional, knowledgeable and independent organisation; our name and brand changing enriches the spirit of the company and we look forward to providing another century of experience, quality and integrity as JG Afrika. Sihluma kunye – we develop together.”
