COVER Taggle Systems

Taggle driving innovation and choice in metering As temperatures soar and the land becomes parched, Taggle Systems innovates and adapts, looking for ways to best save, water utilising digital water metering. TAGGLE HAS BUILT an ecosystem of technologies, partners and solutions to deliver water-saving outcomes to councils and water utilities by offering an end-to-end solution that already includes over 300,000 digital water meters. Collecting and delivering data requires hardware, networks, software, integration and support services, to which Taggle continues to expand its capabilities, adopt new technologies, invest in research and development, and build partnerships. Adopting Telstra NB-IoT “As part of our expanding capabilities, we have partnered with Telstra to provide NB-IoT connectivity,” David Peters, CEO of Taggle, said. Narrowband IoT (NB-IoT) is a communications standard with wireless IoT protocol that uses low-power, wide-area network (WAN) technology. NB-IoT allows IoT

devices to operate and communicate via telecommunications networks. “Telstra has the widest NB-IoT network coverage in Australia, which our customers can now tap into,” said Peters. “Our adoption of NB-IoT has unlocked additional options for our customers. They can now deploy digital meters very quickly and at scale without needing to build a network if one already exists, which is a great solution for urban rollouts.” “We can very quickly get meters installed and projects up and running without having to install a network, which can take time, particularly in urban environments.” Taggle can also support regional and rural areas and black spots in urban areas that might not have NB-IoT coverage with the Taggle Byron network and Myriota satellite network. The adoption of multiple radio technologies has given Taggle ubiquitous coverage across Australia.

The flexibility to choose between various radio technologies to suit different environments and applications provides Taggle customers with unrivalled choice and service options. Expanding range of meters “An ancillary benefit of NB-IoT is the growing range of IoT meters entering the market, which we are looking to include in Taggle’s offering,” he said. “Australia has traditionally installed mechanical meters that use mechanical movement to measure water flow through the meter. However, most NB-IoT meters are static, using ultrasonic waves or electromagnetism to measure water flow.” By understanding the preferences of different clients, Taggle will expand its offering of mechanical and static meters. Peters pointed out that static meters can be fantastic for tracking non-potable water or places with significant turbidity. “We currently have static meters installed for several councils, including Murray River Council raw water schemes,” he said. “In raw

water, there’s a lot of turbidity, so it’s better to have a static meter than something moving physically. It risks getting clogged or broken by things travelling through the pipe.” Large utilities embrace the choice Ultimately, providing different meters and networks is about providing choices to customers. Taggle has recently won pilot programs for three large urban utilities around Australia that are testing Taggle’s new NB-IoT offerings. “These three projects are a great start on our NB-IoT journey,” Peters said. “We have ample experience with deployments and are learning the nuances of the different technologies with these pilots. So far, the pilots are all running smoothly, and all the meters already deployed are operating as we had hoped.” Taggle has positioned itself as an end-to-end supplier, incorporating hardware, software, networks, installation, and management. “Our clients are happy to have us coordinate everything,” said Peters. “If there is a problem at any step of the project, we manage it. We now

provide more options, but Taggle still delivers all the components and ensures the solution works at every stage. We’ve always offered an end-to-end solution and find this works well for our customers. If they want to incorporate other devices, networks or software, we can include that as our ecosystem is open, and we can integrate with other business applications.” Peters acknowledges that some

customers may want to utilise technologies from different providers. “If they want to incorporate other devices, networks or software, we can accommodate that as our ecosystem is open and interoperable, we can integrate with other business applications,” Peters said. “For example, some of our customers use other meters and networks, and others export their data to SCADA and GIS systems.

Technicians can easily set up the NB-IoT devices. Image: Taggle Systems

“We’ve been doing this for over 13 years now,” he said. “We’ll continue offering our end-to-end solutions while building more partnerships to support that ecosystem. We’ve got the devices, the networks, the software and the integration, the project management and installation processes working together smoothly.” The market breakdown When it comes to water meters, it can be hard to envisage how large the market is in Australia. Peters broke it down. “There are about 11 million water meters in Australia,” he said. “About 700,000 digital water meters have been installed nationwide, and Taggle has rolled out about 300,000. That leaves a little over 10 million water meters in the country yet to be converted. 80 per cent of them are in urban areas, representing about 8 million meters. I would expect that by the end of 2035, every water meter in the country will be digital. Taggle plans to be managing a good portion of those.” Peters and Taggle are anticipating significant growth in the near to

medium term. 2023 was Taggle’s best year yet in terms of installations, revenue, and profitability, with 2024 continuing to grow. Finding leaks through data When considering digital water metering, it is easy to get caught up in a technology debate as each method has pros and cons. However, what is essential is the outcomes. Find leaks, save lost water, manage the network, and improve customer relationships. It’s well established that a large portion of treated water is lost to leaks, and the goal is to eliminate as many leaks as possible. “Councils and water utilities often lose 30 to 40 per cent of the water treated through leaks,” he said. “These leaks either occur behind the meter on a residential or commercial property or within the water network.” Aqualus Water, Taggle’s meter data management software, has many tools to identify, locate and notify customers if there is a leak on their property. From the water meter data, the software can quickly identify and alert to large leaks that might go

unnoticed for some time. Councils and utilities can also target smaller leaks right down below 10 litres per hour. When water resources are scarce, these small leaks add up to significant water losses. Identifying and fixing these leaks will save the property owners money, prevent the utility from paying for costly leak rebates and billing disputes, and reduce the demand for stretched water supplies. Last year Taggle identified over 300,000 leaks for example, and notified owners. On average the leaks are then fixed within 2 weeks. This amounts to a huge saving of water. Network leaks present a slightly different problem. They not only result in lost water but also lost revenue as the water never makes it to the end user. Quantifying and narrowing down leak locations can be done using district-metered areas (DMAs). Monitoring DMAs tracks the difference between the water that goes into the DMA and the water used by all the properties. “Once water utilities and councils have identified what DMAs or areas within DMAs have the largest leaks, which is clearly visible in our Aqualus

software, the teams can roll out to conduct more localised leak detections. They can identify the precise location of those leaks and fix them. It’s a way of optimising limited resources to produce the best outcome.” “When a mains break occurs, the data highlights them quickly, and staff can address them before too much water is lost or before the break gets any worse,” Peters said. “Leaks in the network can account for 20 to 30 per cent of all water produced, so there are some huge water savings that can be made in water management.” Community access to the data Taggle’s solution includes a customer portal to inform residents and businesses of their water consumption. Property owners, tenants and agents can sign up to the portal to access leak and high consumption alerts via SMS and email, as well as weekly and monthly email reports, which send a summary including a graph of usage and leaks identified by the system. The set-and-forget design allows people to get information when required without logging in regularly. Directing these notifications to consumers means they are more likely to act immediately. Peters spoke about how some residents have detected leaks of thousands of litres per hour only once the digital meter was installed. “This has happened on properties where the leak is heading into sandy or rocky soil,” he said. “They had no idea they had these large leaks, so they are saving money by taking action and fixing the leak. Equally, the council or water utility saves money because they will not have to process and deliver as much water, leaving more for the environment.” It’s important to remember that

water that leaves the treatment plant has many associated costs. It’s been collected, costly chemicals and energy used to treat it, moved and stored. Delivering water is expensive for any water utility, so preventing losses can have a significant impact. “Detecting leaks and fixing them is a core benefit of digital metering,” he said. Automation and accuracy A key part of the Taggle ecosystem is integrating with billing and business systems. With digital water meters, customers can be billed accurately, and data can flow between Aqualus Water and the utility’s billing system. Setting up these integrations can be a real challenge with many variables across different platforms. However, data can flow seamlessly once in place, improving workflow and minimising errors. “A great thing about councils and utilities is that they are not competing and are very willing to share their experiences and processes,” said Peters. “Once we have developed the integration for a particular piece of software, and even version of the software, as they can vary greatly even from the same provider, we assist our customers by sharing the learnings and best practices with other utilities about to embark on the same integration. With 67 customers, we have integrated with many different

platforms and probably seen it all. Taggle also hosts User Group events and webinars to encourage knowledge sharing between our customers.” Reporting and regulation The data from digital water metering can be of high value when it comes to regulatory reporting and transparency for shareholders. Water utilities must report against non-revenue water. Aqualus Water can assist in populating those reports. The data can also be used in planning and forecasting. For example, the data can be a part of developing new subdivisions. The water utility can calculate the likely highs and lows of a water system for a specific population size, as well as the possible usage profile for that population. These datadriven decisions can save hundreds of thousands, if not millions, of dollars in infrastructure costs. Looking to the future Digital water metering is a proven technology with more choices available than ever. Taggle encourages its future customers to be aware of the array of options. It is an opportunity to start conversations, talk to those who have already gone down the path and learn from their experience. The benefits are significant and well worth the investment.

YOUNG PROFESSIONALS Ibrahim Hakeem

Reducing contamination in biochar Award winner Ibrahim Gbolahan Hakeem has been studying the recovery of heavy metals from biosolids and their impacts on creating biochar through pyrolysis. How can he help the water industry improve using his research? IN LATE OCTOBER, the Australian Water Association’s (AWA) Victorian Water Award winners were announced at a glittering ceremony. Several organisations and individuals were recognised for their inspiring leadership, innovative research, programs, and infrastructure projects. Among the winners was Ibrahim Gbolahan Hakeem, a PhD student at the Royal Melbourne Institute of Technology (RMIT) University. He’s now a postdoctoral researcher at RMIT. Hakeem is also part of the

Australian Research Council (ARC) Biosolids Industrial Transformation Training Centre and the Water Research Australia (WaterRA) research leadership program. Hakeem completed his Bachelor of Engineering at Federal University of Technology Minna, focusing on chemical engineering. It’s one of the few specialised universities of technology in Nigeria. Following the completion of his bachelor’s degree, Hakeem received a Commonwealth Shared Scholarship to attend the University of Bath in the United

Kingdom. He completed his Master of Science, majoring in sustainable chemical engineering. “I had a different direction in mind when I first started my bachelor’s degree,” said Hakeem. “Nigeria has a significant oil, gas, and petrochemical industry, so I originally thought I’d be heading down that path. However, once I entered the program, I got to understand more of what chemical engineering can do.” This led to Hakeem’s interests changing, with a new focus on process design and developing technologies for waste management. However, the shift to the water industry came about during the completion of his Masters. “My Masters’ project focused on the conversion of aquatic biomass using hydrothermal processes,” he said. “I was specifically looking at microalgae, water hyacinth, seaweed, and related materials. It was at this point I started studying water-generated waste resources with more focus on sewage sludges and wastewater treatment residues.”

Australia and the water sector Once Hakeem moved to Australia, he studied at RMIT to complete his PhD. His work focused on developing integrated chemicalthermal processes for converting biosolids to high-quality biochar. “I’ve just finished my PhD on the development of new valorisation techniques and improvement of pyrolysis process for the production of biochar, bioenergy, and chemicals from biosolids in a biorefinery context,” he said. “There’s been a lot of interest in the work I have done by the industry. Our research group here at RMIT, led by Professor Kalpit Shah, has significantly impacted the water industry.”

Studying under Kalpit Shah, Hakeem has grown from strength to strength. “My professor has been working with the Australian water sector for some years now,” Hakeem said. “I’ve been working in the biosolids training centre, which has been looking at developing solutions for biosolids resources in Australia.” The industrial transformation training centre seeks to have the water industry work in conjunction with academia to find long-lasting solutions to water problems. “Working in the centre has allowed me to connect with water professionals across the country, create that impact and get their perspective in the initial

stages of my work,” he said. “The water industry has been a great collaborator of our work.” Removing contaminants from biosolids Removing contaminants, such as heavy metals, from biosolids is important for water utilities wanting to increase the sustainability of their operations. “When I started my PhD, I was looking at that topic in a broad sense,” Hakeem said. “When I started to develop the scope and identify the gaps in which I could have the greatest impact, I sensed that the water sector was a bit sceptical about the opportunities that could arise from the non-

intense heat (typically between 300 and 650 degrees Celsius), there is a range of heavy metals and inorganic contaminants that remain stable. Those contaminants remain in the biochar but at a higher concentration due to a significant reduction of organic matter. “The goal is to make pyrolysis technique more sustainable for the water industry,” Hakeem said. “We thought about whether we should remove the heavy metals before or after pyrolysis. My research focused on removing the heavy metals from the biosolids before pyrolysis. That produces biosolids free of contaminants, improving the overall quality of the derived biochar for land application.”

agricultural use of biosolids, particularly those involving thermal treatment such as pyrolysis.” One of the biggest concerns was around legacy contaminants such as heavy metals. There was also concern about the growing range of emerging contaminants, such as PFAS and microplastics. “This drove my interest in exploring alternative treatment methods,” he said. “Pyrolysis is one of the developments that is gathering significant traction in the water space.

The industry is now in a position to develop pyrolysis at large scale.” Pyrolysis is the treatment of organic materials through heat under an oxygen-deficient environment to create biochar, a carbon-rich solid residue. Biochar is the lightweight black residue (or char) that remains after the pyrolysis of biomass and can have applications, including soil amendments, fertilisers, adsorbents, and energy storage. While most contaminants are destroyed in the

Pyrolysis in action Hakeem recently spent time conducting some research at the pyrolysis plant at the Melton Recycled Water Plant. The pyrolysis plant (known as PYROCO) was a combined effort between South East Water, RMIT University, Greater Western Water and the Intelligent Water Networks (IWN). “I wanted to study how biosolids generated from different types of wastewater treatment facilities will behave during pyrolysis,” he said. “One of the processes developed within my PhD has been to enhance the pyrolysis conversion of biosolids by subjecting them to mild acid pre-treatment. I found that the selective removal of heavy metals and ash-forming elements during the pre-treatment process facilitated organic matter conversion to quality biochar and bioenergy. The raw and treated biosolids reacted differently during pyrolysis, creating different benefits to product

yields and properties.” What Hakeem was able to determine from the trials is that biosolids that contain more ash, minerals and heavy metals are far more difficult to deal with because they have less energy content to convert. That means Hakeem’s research will be pivotal in removing these contaminants before undergoing pyrolysis. It will improve the process efficiency and product quality. “I believe that pyrolysis promises to offer many benefits to the water industry,” said Hakeem. “We’re getting some serious interest from the entire sector, and there’s a lot of excitement there. The commercialisation prospects of the PYROCO technology are growing fast, including the deployment of mobile pyrolysis plants. They can install that onsite for the sustainable conversion of biosolids and biowaste. That creates a localised market for the products.” Award winner As the Victorian winner of the Student Water Awards, Hakeem said it was an honour to have received the award. “It shows our commitment and dedication to researching wastewater treatment and biosolids management,” he said. “I felt so celebrated. My supervisor was also very proud of the work we are doing for the Australian water sector, and to be recognised for that. We are looking forward to the next stage, which will be the national final.” That national final will take place during OzWater’24 in Melbourne from Tuesday, 30 April, to Thursday, 2 May. The award will be one of several that will be given out at the event.

Trends and the future Hakeem believes that the Australian water sector is a true world leader in identifying new ways for sustainable management of biosolids. They are also at the forefront of developing costeffective thermal technologies such as pyrolysis and gasification. The goal is to improve the current management options for biosolids and facilitate the adoption of new technologies that can reduce biosolids volume, safely destroy

contaminants, and generate highvalue products in a circular economy approach. The Australian water industry are making giant strides in this regard, he said.. When it comes to his future, he wants to remain in the biosolids pyrolysis research. Many areas need work, and Hakeem intends to be at the forefront. “I see myself working in this space and developing much-needed technological solutions to challenging water sector problems.”

WaterAble supporting access for all WaterAble is supporting positive outcomes for people with disabilities in the Australian water sector. Their programs maximise opportunities for people across the industry. THE WATER INDUSTRY across Australia is one of the more diverse and inclusive industries, employing many women and people from culturally and linguistically diverse backgrounds. However, the employment of people with disabilities has been growing in impact across the country. Advocates would argue that there is more to be done when it comes to employing people with disabilities in any industry sector. According to the Australian Institute of Health and Welfare, working-age people with disabilities are twice as likely to be unemployed as those without a disability (10 per cent compared to 4.6 per cent). They also have a lower employment rate (48 per cent) compared to those

without a disability (80 per cent). Many industry segments are seeking to increase opportunities for people with disabilities. The water industry is one such sector, and organisations like WaterAble are working to support people with disabilities. Donald Hughan is the Chair of WaterAble, with Matt Iversen as the Deputy Chair. Both have been involved in WaterAble for several years and believe that education is a crucial focus of WaterAble. “The role of WaterAble is to educate and create awareness to the broader workforce,” said Hughan. “We want to show the industry that people with disabilities can contribute in a meaningful way. People

must learn how to provide that encouragement and create safe spaces for their employees.” “It’s also about evening the playing field,” said Iversen. “I’ve felt disadvantaged by my personal circumstances. This isn’t anyone’s fault, but it’s the unfortunate situation I have found myself in. Diversity and inclusion initiatives can make a workplace more comfortable or more accessible, so it just creates something where people with disabilities have equal access and equal opportunity when it comes to applying for roles.” How does WaterAble help? Advocacy groups like WaterAble are essential for bringing awareness to the issues pertaining to the industry. “We can help companies become aware of the barriers that impact people with disabilities,” said Hughan. “We can work together to break down those barriers and make things more accessible

“ Work is such an important

for people with disabilities. We also want to help them retrain, become employed and contribute to society. It all builds towards having fulfilment in what they are doing and enjoying what they are doing.” One thing WaterAble focuses on is educating members of the water industry. While the sector is generally very reasonable, there are opportunities to learn more. “Organisations like WaterAble can give a voice to people who

might not normally have access to senior leadership within the water industry,” Iversen said. “These leaders might need to be made aware of reasonable adjustments and other things that impact the lives of people with disabilities. People like Donald and I have that lived experience, and we can speak about them to the industry leaders. While small changes have been made quickly off the back of our work, we know that things can take a long time.”

”

Supporting people with disabilities VicWater has backed WaterAble in recent years. This collaborative approach has helped WaterAble to expand into all the water authorities in Victoria, and it has recently expanded to a national program. Within that, there are a range of opportunities available to its members. “We do industry workshops, meeting with the Victorian water corporations,” Iversen said. “With

www.insidewater.com.au INSIDE WATER

FOCUS Diversity and Inclusion

our national expansion, WaterAble is looking to increase its reach. There are a lot of organisations that are making positive changes in hiring practices and environments in the workplace.” These industry workshops came about through the leadership of Llewellyn Prain, the founder and now National Coordinator of National Partnerships for WaterAble. Prain is also the deputy chair of Greater Western Water. She is also in charge of the mentoring program, where she has mentored people with disabilities within the water industry. One thing that the industry has lauded is the inaugural Leadership Program. Running through the second half of 2023, the four participants graduated in a ceremony at the end of November. “These are people who are identified as having a disability and

working in the water industry,” Hughan said. “They also want to build their leadership capabilities and develop that skill set. It’s been an excellent program.” The program is designed for people with disability in the Australian water industry to help build their leadership potential. It also supports their personal and career growth. The program explored different leadership frameworks and approaches. It provides resources for further reading and exploration. It is a safe place for people to explore who they are, what they want to achieve and how they want to go about it. It will also include practical elements to put the theory into practice. Improvement for the future Both Hughan and Iversen agreed that supporting people with

disabilities so they can work is a crucial goal of the organisation. “Work is such an important thing to people,” Iversen said. “It’s one of the big aspects of your life. Feeling comfortable and being able to contribute as much as anyone else is a massive motivator. I want to see people get the same opportunities that I’ve had, and I want that to be available to people with disabilities different to mine.” “Corporations in the water industry can encourage people with a disability to apply for positions,” said Hughan. “People will find themselves fulfilled when they have a job and can contribute to society. They will learn life skills, receive a salary, and build their competencies to grow as a person.” For more information, visit waterable.com.au

A SUCCESSFUL FUTURE for businesses in today’s commercial environment involves more than simply doing business. It’s about delivering on a purpose and improving the lives of everybody with whom the organisation comes in contact. Interflow provides water services from the far north of Queensland to the Pilbara region in Western Australia, New Zealand, and the southern reaches of Tasmania. One ingredient in the recipe for success is the organisation’s Reconciliation Action Plan (RAP). It’s a framework for knowledge, learning, processes, and initiatives that benefit everybody in and around the business. Interflow is currently 18 months into

the Reflect RAP journey, which helps shape how the organisation will engage with reconciliation. But the RAP is so much more than that. The three key focus areas for Interflow from a business perspective involve encouraging cultural respect, unlocking Aboriginal and Torres Strait Islander talent, and developing partnerships. It wants to attract Indigenous people, better appreciate and understand Indigenous communities and further develop its supply chain. Most importantly, Interflow knows it’s simply the right thing to do. The feedback it receives from its people is very positive and acknowledges that every business can play a role in reconciliation.

A RAP is a learning journey Australia’s First Nations people are a part of the oldest continuing living culture in the world. The more stories Interflow hears about how they have interpreted and managed the land during their 65,000-year custodianship, the more it realises how much can be learned from that knowledge. “There is a lot we can all learn from our First Nations people,” said Frank Phillips, Interflow’s Executive General Manager QLD/WA/NZ and RAP representative. “Governments are starting to step up, listen, and learn more. Some state governments, for example, are employing or consulting with Indigenous experts to understand how to practice better land management.” “The connection we have is water. Water is essential to us as a business,” he said. “But we won’t sit back and say we’re experts and know everything. This RAP process so far has taught us that we need to take the time to listen to the feedback we’ve been getting from Indigenous people. If we listen, we’ll learn and constantly evolve.” Initiatives connected to the Interflow RAP program include

leadership cultural awareness sessions hosted by Wurundjeri Elder, Uncle Bill Nicholson Junior. Uncle Bill explained how the business’s projects could impact sacred lands and how Interflow can better engage Aboriginal and Torres Strait Islander groups and contractors. Interflow has partnered with Supply Nation. So far, it has provided more than $1.5 million to businesses certified by the Indigenous business facilitator. The business also partnered with majority-owned Aboriginal and Torres Strait Islander business Indigenous Project Services Australia. The goal was to deliver a fivekilometre sewer reticulation pipeline on the Royal Australian Air Force base in Amaroo, Darwin. A RAP brings pride and loyalty One of the biggest responsibilities of the 20-strong RAP Working Group is to communicate the RAP’s purpose to the organisation and beyond, said Phillips. “We’ve got a very eager working group,” he said. “We’ve found a rhythm and empowered everyone in the group to be champions for the RAP. We want to make sure the entire organisation really embraces it.” The education that comes from

exposure to the RAP program, knowledge around a culture that is so integral to the essence of what it is to be Australian, is highly valued by Interflow’s people, as it is by people within all businesses that are on the RAP journey. Interflow is on a journey towards reconciliation. But it’s also about taking the opportunity to understand a vital culture and to bring others along on that journey. Many people across Interflow are coming forward and putting their hands up to be part of this. While the company knows it lacks expertise in this area, it intends to help and support people along that journey. The value of the RAP process is quite personal and simple. “To understand this better will make you a better person,” Phillips said. “It will make you more balanced and knowledgeable, and it will help you develop a much better understanding of a culture that is a part of our lives.” Getting it right Why is Interflow putting so much effort into getting the Reflect RAP process right? Because it matters, Phillips says. It matters that as many businesses as possible become a part of the solution to First Nation people

being the most disadvantaged in Australia. “This is not a tick-a-box for Interflow,” he said. “It fits within the bigger picture of our diversity and inclusion strategy from a people and capability perspective. At the same time, it makes real business sense. Hopefully, it will have a far broader and very positive effect. From our Board, Managing Director, and leadership team, we want to truly understand it, and our people are telling us they want to come along on the journey.” As Interflow’s Reflect RAP document says, We aim to achieve the most sustainable outcomes for our customers and communities. We respect the land on which we operate and have led the development of world-class trenchless technologies that eliminate or reduce the need for excavation. Our core values of Honesty, Respect, Reliability, and Competence underpin everything we do. Our values are the cornerstones of our success and are embedded in our DNA. They inform the way we do business with ourselves and others. For more information, visit www.interflow.com.au

Diversity and inclusion in Queensland water sector

While Queensland’s urban water sector has historically been male-dominated, statistics gathered by the Queensland Water Directorate (qldwater) for its biennial Urban Water Workforce Report show that assumption may no longer ring true.

The Biloela sewage treatment plant presents an opportunity for women to get involved in the water industry. Image: qldwater

QUEENSLAND WATER DIRECTORATE (qldwater) biennial Urban Water Workforce Report shows a positive move towards gender diversity, as well as quantifying some concerning workforce challenges. This includes high vacancy rates (15 per cent for water plant operators, for example). It also showed extended vacancy durations of up to and beyond a year for a range of critical occupations. The present picture As of November 2022, 6,711 people were directly employed in the Queensland Urban Water Industry. This is compared to 6,686 recorded in 2020. The workforce typically comprises water operators (civil, treatment and dams with some irrigation), engineers, trades, trade

waste, science/technical professions, management, and business support functions. qldwater’s report reveals some of the sector’s complex challenges. Those challenges include an ageing workforce, attracting and retaining staff, and competition from other industries (particularly resource industries). A range of other factors create an environment that is compounding the longer-term skills and labour shortages. For example, most of the workforce is aged between 31 and 60 years old. Nine per cent is over 60. Although this has been a consistent trend since reporting began in 2010, the nature of some of the roles is physically demanding. Early retirements and occupational detachment from such

INSIDE WATER January/February 2024

positions occur at relatively younger ages. The report also draws attention to the increased retirement rates from specialised occupations such as dam operators, which has been pronounced over recent reports. While the water industry remains male-dominated, the gap between male and female employment is closing. The percentage of female employees across the State increased by 8 per cent from 2020 to 2022, the biggest increase since reporting began. The most significant uplifts in female participation were in trades (up 32 per cent) and civil construction and maintenance (up 37 per cent). Training is key The Certificate III in Water Industry Operations is still the most used qualification in the National Water Training Package (NWP) at 70 per cent, maintaining its position as the predominant qualification for Queensland’s water/wastewater treatment operators and supervisors operating conventional treatment systems. These rates of achievement

have increased over recent years. However, the public provider of training for the sector (TAFE) withdrew from the delivery of the NWP in May 2022. This has already negatively impacted the sector’s access to and choice of training (particularly subsidised training). The long-term impact on the industry is still to be determined. Trends towards increasing

technology, community expectations, outsourcing and legislative reform emphasise the need to address workforce, training, and professional development challenges to ensure operators of urban water facilities are competent, adequately supported, and qualified to run their sites successfully and in a manner that protects the environment and community health.

Measure to manage Due to the nature of Queensland’s urban water sector workforce being employed by a range of entities, including local governments, statutory authorities and governmentowned corporations, accurate reporting of diversity metrics across the sector remains challenging. For example, mandatory reporting to the Workplace Gender Equality Agency for ‘relevant employers’ is limited to larger employers (100 or more employees). There are rules around corporate groups and the public sector. At the same time, other data sets subsume water into the broader utility sector, with the urban water sector appearing as a subgroup, which in some cases is too small for publication. The data and industry insights collected by qldwater indicate that much of this sector is behind in measuring efforts around diversity data collection and analysis - but it is not alone. A recent Australian HR Institute (AHRI) report (2023) shows fewer than half (45 per cent) of HR professionals actively measure the

diversity profile of their organisations. This is not surprising. The collection of the right data can be resource intensive, not least to ensure correct procedures and regulatory requirements are met, but because the nature of this data is personal and for some employees, revealing diversity information can be confronting. Diversity is what makes each of us unique. It includes people’s backgrounds, personalities, life experiences and beliefs, all the things that make them who they are, not least ethnicity, gender, age, race, religion, disability, and sexual orientation. Data collection practices that recognise the vast array of diversity demographics are an increasing expectation and a critical tool to ensure that each individual and the workforce they represent are visible. As such, qldwater is expanding the range of workforce metrics in future workforce surveys and other reporting.

make a positive difference to the organisation and its workforce. How organisations manage diversity and intersectionality (individuals experiencing more than one aspect of diversity, such as First Nations women or an older worker with a disability) is increasingly important. A person’s individual characteristics affect their experience of the world and their workplace. They also provide them with unique perspectives, skills, and capabilities. This is also true for workers from other sectors. As an essential service sector experiencing critical workforce

shortages, the industry needs to ensure that it is an attractive employer to a range of individuals and that the industry’s work environments are accessible. The industry has an ethical (and legal) obligation to do so. It also needs to include the unique characteristics of large proportions of its community as a potential workforce to benefit the sector. After all, inclusion only occurs when people feel and are valued and respected. For more information, visit qldwater.com.au

Managing the challenges While data and measurement are important, it is essential to understand what data is and is not needed, and how it will

Providing opportunities through Programmed Programmed has been at the forefront of supporting the water industry through its facility management operations. Its initiatives around diversity and inclusion (D&I) are providing the best people for the roles. PROGRAMMED’S APPROACH to diversity and inclusion (D&I) is about practical steps. This approach is less about ‘big’ programs or women-specific programs. Instead, Programmed aims to achieve diversity and inclusion balance through embedding sustainable changes to have a more diverse and inclusive team. People like Rebecca Ower, one of the regional human resources managers, are working to get people into jobs across the water and wastewater industry. “I sought an opportunity within a company where I could leverage my skills in working with and developing individuals to help them excel in their roles,” Ower said. “Equally important to me was finding an employer whose values aligned with my own. Programmed turned out to be the perfect fit for me in both respects.” She is part of the multi-faceted approach that Programmed takes. It focuses on encouraging girls and boys to study science, technology and trades, engineering, and mathematics (STEM) subjects at primary and secondary schools. At a community level, it wants to challenge the stereotypes and advocate for people to think about what they say and do to influence young people and their future directions.

Challenges Ower believes that the biggest challenge for the water industry is the lack of understanding of what the industry is about. “In the realm of facilities management, and by extension, the water industry, there is a noticeable scarcity of opportunities that effectively showcase job opportunities,” she said. “When such opportunities are presented, the efforts are often suboptimal, typically emphasising behind-the-scenes activities. This presents a significant hurdle in recruiting individuals within the facilities management and water industry, amplifying the challenge of attracting suitable candidates.” What is Programmed trying to do to solve this issue? Programmed has crafted initiatives to heighten awareness

of occupations traditionally underrepresented by women or individuals from diverse Culturally and Linguistically Diverse (CALD) backgrounds. Moreover, it actively organises purposeful and engaging visits to schools and communities, where insights into various careers are shared, fostering encouragement among young girls and culturally diverse individuals so they may see the broader opportunities available to them for future career paths. “We’ve also devised and implemented ‘Try-a-Trade’ days,” said Ower. “It allows young people to experience firsthand the life of a tradesperson. This provides valuable exposure and also creates additional opportunities to cultivate gender and generational diversity, supported by real-life examples.”

Water and wastewater industry are leaders Programmed remains committed to its strategy of enhancing women’s representation in leadership roles and attracting women to trades and operations. The company has actively collaborated with specialised organisations such as the National Association of Women in Operations (NAWO) and Tradeswomen Australia to achieve this. These partnerships aid in developing targeted talentsourcing strategies for specific recruitment opportunities, whether in leadership, trades, or operations positions. Ower reflected on Programmed’s efforts, stating, “From a Programmed perspective, the water

and wastewater industry excels in terms of diversity and inclusion operations, particularly when compared to programs in other industries.” She emphasised the organisation’s

aspiration to achieve a 50/50 gender split among new apprentices, trainees, and graduates, noting the significant progress made in some sectors of the water industry. “Traditionally, attracting women to the industry has been challenging,” Ower remarked. “But over my six years with Programmed, achieving a near 50/50 gender split in our recent apprenticeship program is a testament to the fantastic work of our teams.” The initiative to attract and recruit female candidates for trade apprenticeships aligns with Programmed’s broader goal of increasing female representation in trade roles. This strategic approach not only addresses the gender gap but also contributes to building a diverse and talented pipeline for future leaders, which better reflects the communities they serve. Moving forward Programmed are members of the Business Council of Australia’s working group on STEM to develop an evidence base and to clearly identify the critical issues that need addressing. It also subscribes to the Male Champions of Change approach and thinks men must actively drive change. “We aim to create and maintain a

safe, inclusive and diverse culture across the business inclusive of the water industry,” said Ower. “That is about recognising, respecting and valuing all people.” Promoting success stories with profiles of Programmed’s female employees in trades and operations roles is key to developing opportunities for women and other diversity groups. Similarly, Programmed has worked with its customers to encourage girls and boys to consider trades as a career pathway. Taking a leadership role Programmed is a firm believer in having a clear diversity strategy. That’s not just for itself – it extends to its clients. “We collaborate closely with our clients to integrate our social procurement platforms seamlessly into our operations,” she explained. “Additionally, we actively seek to engage community organisations in developing programs to foster

inclusivity. These organisations may encompass a wide range, such as disability groups, First Nations groups, and women’s programs, to name a few from a potentially extensive list.” “It revolves around the initiatives that Programmed employs to enhance outcomes for its clients while actively listening to their unique concerns. Recognising that

each client holds distinct priorities, Programmed is committed to customising programs according to their specific needs. The goal is to involve clients in the journey of enhancing diversity and inclusion, ensuring a collaborative and tailored approach.” “We organise expos to spotlight our clients and their respective industries,” Ower explained. “Our aim is to offer tangible examples to potential employees by featuring individuals who can share their firsthand experiences in the industry. This approach is crucial in breaking down barriers for individuals considering a career change. For instance, having female apprentices and tradespeople visit schools to articulate their personal journeys serves as a powerful and relatable example.” The future of D&I for the water industry is only positive in the eyes of Ower. “There are so many different areas that you can be involved in when it comes to the water industry. The more we showcase the industry, the better it gets.” For more information, visit programmed.com.au

They can be utilised on a range of pipe materials, including steel, DICL, HDPE, concrete and MSCL carrier pipes. This minimises running friction between the carrier pipe and the casing during installation. The HDX casing spacer comes in four runner heights, ranging from 38 to 125 millimetres. The HDXT casing spacer also comes in four runner heights between 43 and 153 millimetres. The different runner heights across the two models ensure pipeline installers can handle a range of carrier pipe OD and casing (host pipe) ID combinations. It allows for customising the pipe position for grade control or ‘centring’. kwik-ZIP provided HDX65 casing spacers for a bundled conduit installation carried out by Diona Civil Engineering for Ausgrid.

Future stormwater management in Australia There are many advocacy groups for different aspects of the water industry. Cath Thrupp is the president and chair of Stormwater Australia. She spoke about its role in the water industry. MANAGEMENT OF WATER on the 2nd driest continent on earth is never going to be easy! Sharing experience and knowledge is vital to supporting effective outcomes. Groups like Stormwater Australia are making significant contributions to the stormwater industry. Formed in 2000, Stormwater Australia engages with state and federal authorities to advocate for evolving stormwater needs. It also seeks to raise awareness of national stormwater challenges and to provide knowledge sharing and certification programs for the industry. Stormwater Australia members have protected the environment, served communities,

and supported sustainable stormwater solutions since its founding. “We have a very diverse membership base,” said Cath Thrupp, the president and chair of the board of Stormwater Australia. “They broadly fall into three categories. The first is local government, which manages large stormwater asset bases in Australia. The second group are manufacturers and sellers of products in the water space. Thirdly, we have consultants that are working in the water industry.” Importance of stormwater Thrupp believes that stormwater management can be both

challenging and exciting. Water touches every aspect of the urban, rural and regional landscape. “Stormwater managers are never managing just one part of the city or landscape,” she said. “You have to take a broader perspective on the rainfall or total water cycle. Water lands on farms, roads, buildings, and green spaces and flows into our existing stormwater pipes and natural waterways… It’s quite complex to work out how to manage that water holistically. As this water flows, it transports contaminants that need to be managed and treated before flowing into waterways and bays where people swim, boat and fish.” Looking to the future, there are some emerging challenges for stormwater and water managers. One such challenge is climate change, which poses ongoing challenges due to extreme weather events and rising sea levels, leading to issues with urban heat, water

supply issues, droughts and floods. “A lot of our stormwater systems were never designed to deal with some of the extremes we’re seeing across the country,” said Thrupp. “It is something that we are seeing across Australia and worldwide. Massive storms roll through our cities, leading to large water flows to stormwater networks. There’s no way for our current stormwater infrastructure to cater for these extreme events.” In the future, there will also be challenges with managing aging stormwater assets already in the ground. Thrupp believes that this is an issue that needs to be discussed more. “Due to the age of our cities in Australia, many Local Governments have extensive pipe networks that are managed in conjunction with waterways and water-sensitive urban design stormwater assets above ground,” she said. “Many of those pipe networks are approaching the end of their lives. That becomes a problem for local government because renewing thousands of kilometres of stormwater pipe infrastructure is an extremely costly exercise, and not one that many cities have the funds to deal with.” Stormwater strategy At the beginning of 2023, Stormwater Australia published its Strategic Plan for 2022-27. Within this strategic plan,

Thrupp believes there are three key points. “Firstly, Stormwater Australia is taking a future-focused view of what is going to be needed for stormwater going forward,” Thrupp said. “We want to focus on what a sustainable, resilient city of the future might look

like. Globally, a lot of work is being done on how to design resilient infrastructure for the future. No city, town or region can transition to sustainability and resilience overnight, so long-term planning is critical.” Innovation is the second point.

FOCUS Stormwater

Stormwater Australia wants to support its members by developing new tools and sharing the latest global technology with its community in real time. The goal is to engage more effectively with members and share knowledge and training across the community. “To deal with climate change and other emerging challenges, we have to leverage the latest technology and come up with ideas that we’ve never considered before to adapt,” Thrupp said. The third point is collaboration. The water industry is already collaborative, and complex challenges need even more cooperation around the globe. We need the smartest people worldwide to work together to adapt for the future. Sharing things that have or have not worked well is fundamental to the growth of the stormwater and water management sectors. Trends in the industry Stormwater Australia is paying attention to several trends in the stormwater sector. One is the

effective and innovative design of a city or landscape’s green, blue and grey elements. “Stormwater was historically focused on grey infrastructure, being the pipe and drainage networks,” said Thrupp. “With an increasing focus on liveability and infrastructure that serves multiple purposes, the attention is now focused on effectively integrating those existing networks with green spaces and natural waterways. Managing urban liveability

requires the effective integration of water into the landscape to achieve a range of outcomes, such as flood management, water quality, community recreation and biodiversity outcomes.” “With climate change and a sustainability focus for cities, there’s a big demand for green spaces and urban rivers and creeks,” she said. “People want that close relationship with their local green and cool spaces. We know there are social and health benefits associated with recreation along waterways and around our coasts and bays. We are focused on how stormwater contributes to that broader urban design outcome.” There is also a significant change in how technology is being used to help design effective stormwater outcomes. “Cities and utilities are using digital twins to run different design scenarios,” Thrupp said. “This helps manage and design optimised water and liveability outcomes. Technology also plays a key role in water treatment and quality improvement. Technological breakthroughs are rapidly transforming the industry in diverse ways.” For more information, visit www.stormwateraustralia.com.au

State-wide stormwater approach Supporting integrated water management is a priority for many water utilities and local councils. South East Water works with multiple groups to help manage stormwater through its catchment areas. “OUR POPULATION IS growing, and climate change is happening,” said Suresh Bajracharya, South East Water’s Integrated Water Management Planning Lead. “The sources of water we currently have are not going to be enough to provide water security for our customers in the future. We need to expand the use of stormwater as a water resource.” It’s this thinking about stormwater that Bajracharya is implementing as part of South East Water’s strategic partnerships on stormwater. Originally from Nepal, he studied at Tribhuvan University, its oldest and largest university. “When I was at school, we were taught that Nepal is the second richest country in the world when it comes to water resources,” he said. “When I looked at the situation in the villages of Nepal, most people would travel for hours to meet their daily water needs. That didn’t sound right, and I wondered why we could not manage our water resources properly. That would save my people

from their hardship and poverty.” Once he got to university, he learned that water resources management is a global issue. Immediately after graduating from university, Bajracharya joined Kathmandu Metropolitan City as a civil engineer. Moving to stormwater In 2007, Bajracharya joined Melbourne Water. He started as a drainage specialist, analysing the catchments flagged for growth and redevelopment. Bajracharya then had to develop drainage and flood management solutions for each catchment. “Melbourne was at the tail end of the 2008 millennium drought,” he said. “Australia had learned, in a very challenging way, that every drop of water does matter. I had just completed my Masters in Water Resources Management and was bubbling with many optimistic ideas. There were a lot of opportunities to capture rainwater and stormwater in many of the greenfield development areas I was working on.”

INSIDE WATER January/February 2024

The development of Fishermans Bend provides unique opportunities to manage stormwater in a holistic manner. Image: South East Water

This would reduce the potential flood management challenges and the pressure on Melbourne’s future water services. It would also provide an opportunity to reduce the impact of water restrictions. During this period, Bajracharya switched focus from pure drainage and flood management to the holistic management of stormwater. Working with stormwater Melbourne Water and local councils are the designated authorities for managing stormwater in Melbourne from drainage and waterways perspectives. Historically, retail water corporations have had no official role in stormwater management. That is changing. “Water authorities have become increasingly interested and involved in stormwater management,” said Bajracharya. “That’s particularly the case when it comes to its use as a water resource. Using stormwater as a water resource is a relatively new concept. The roles and responsibilities for this service are not allocated to a single agency.” South East Water sees its role as collaboratively working across the industry to help maximise the potential of stormwater in providing water security. It also offers other benefits that build into environmental protection, flood

mitigation, and liveability. “South East Water published its stormwater strategy plan last year,” he said. “It articulates our vision and collaborative roles in stormwater management. We have five key areas of focus within this plan.” Stormwater plan The first area focuses on policy influence. South East Water remains focused on the development of enabling policies, regulations and operating frameworks that facilitate stormwater harvesting. “Collaborative planning with the industry is the second area,” said Bajracharya. “We want to develop a shared vision and agreed plans for holistic water cycle management solutions that consider stormwater harvesting and reuse.” South East Water believes in the importance of implementing strategic and collaborative partnerships. Such relationships are vital for developing integrated plans and programs. In that way, water authorities can work with councils and other stakeholders

Image: South East Water

to provide better holistic stormwater management throughout its service region. “Innovation is a key feature of South East Water,” he said. “Innovation through partnerships in research and development of products, technologies and services are all key to how South East Water and other water authorities can support stormwater management initiatives. These all work to improve effectiveness and affordability, as well as the scale of rainwater and stormwater harvesting solutions.” Finally, customer and community engagement are fundamental parts of the operations of a public water utility. They need to educate the community so people are aware and appreciative of the benefits of using stormwater and rainwater. Developments within the stormwater industry In the eyes of Bajracharya, he can see a series of technological and non-technological developments influencing the stormwater management industry. Even though stormwater and rainwater are not part of the regular service domains for the utility, they are still involved in an array of research and development activities around stormwater and rainwater use.

“One example of our technological developments is our range of smart rainwater tank technologies,” said Bajracharya. “South East Water has implemented them in its Aquarevo development. The smart tanks can be controlled remotely and operated to maximise water use and enhance flood mitigation. We’ve seen a 26 per cent reduction in stormwater runoff across the entire development area.” These smart tanks are being trialled in properties in Fishermans Bend, ahead of their potential rollout across the development site. There has been interest in these smart tanks across Australia and around the world due to their water saving and stormwater management functions. “We are also working with councils beyond our catchment areas,” he said. “Our smart sensors are being used to enhance the waterway management functions and improve the habitat for platypi. It’s an example of how we lead in real-time monitoring and controlling technology for wetlands and waterways.” When it comes to nontechnological developments, a shift has been looking at stormwater as a valuable water resource. Stakeholders and the community appear to support this shift, which provides South East Water and other water authorities the social license to get involved. “Stormwater is being spruiked as a potential potable water solution in multiple industry and community discussions,” said Bajracharya. “It’s getting momentum, and a successful project is already operating in New South Wales. There are also similar projects overseas, so we are learning as much as possible to advance further in this field.” For more information, visit southeastwater.com.au

Storming in to improve asset and flood management Having the proper infrastructure to deal with stormwater is critical. UK case studies have shown how Pulsar Measurement has the instruments and sensors to support customers’ needs. THE UK WATER industry has a new set of regulations around stormwater management. Monitoring any spills going into a storm tank is now required. In the UK, this is referred to as UMON3. This requirement ensures that all data is recorded to a specific standard. That way, water utilities are confident in the reliability of their flow readings. The Monitoring Certification Scheme, also known as MCERTS, provides a framework of standards for safe and reliable liquid flow monitoring. It is used throughout the UK water industry to ensure that water bodies work towards the same standards. MCERTS is also designed to protect the sewage networks and local environments. MCERTS has been based on international standards. It provides for the product certification of instruments, the competency of personnel, and the accreditation of laboratories. The performance standards for MCERTS are based on relevant sections of several international ISO or CEN standards and other national standards.

Device manufacturers can show that they have an independent and authoritative endorsement of their products. It improves their access to international markets and increases their uptake in the UK. Pulsar Measurement has announced that the Ultra 4 has achieved MCERTS Class 1 Certification in flow measurement combined with the dB3 transducer and double sun shields.

Pulsar Measurement’s UltraTWIN controller is designed to support water authorities and municipal government to manage stormwater. Image: Pulsar Measurement

MCERTS approved flowmeters MCERTS-approved flowmeters have been approved under a certification scheme formally recognised in England and Wales. The scheme is also accepted internationally. Approval under MCERTS gives confidence to regulatory authorities that the devices are fit for purpose. Those devices can also produce consistent, high-quality results. There is also data that confirms performance standards accepted by UK authorities, which increases transparency opportunities for regulators, users, and the public.

Severn Trent Water improving network Fifteen properties in the village of Kirk Hallam in Derbyshire were prone to flooding. It prompted the upsizing and general sewer network improvements from Severn Trent Water. Construction engineering company nmcn was tasked by Severn Trent Water to improve the sewer network that runs through the village of

Kirk Hallam. They used the Pulsar UltraTWIN controller and two dB10 transducers. The contractors successfully measured the main trunk sewer and the water levels in an offline shaft tank. Nmcn partnered with its customers to deliver several built environments and critical national infrastructure projects across the UK. Its specialist engineering and construction teams brought multi-sector innovation and technical skills. It has worked on projects from buildings and highways to large-scale water networks and treatment plants. When it came to the village of Kirk Hallam, nmcn plc was responsible for alleviating the flood risk to 15 properties located within the village. The project included the installation of an offline stormwater shaft tank. This tank does not receive constant flow to pump away and only comes

into operation during long periods of rainfall/storm conditions. This is a common application throughout the UK water industry. Pulsar Measurement products support Severn Trent Water upgrade A Pulsar UltraTWIN controller and two dB10 transducers were installed. They were used to measure 7.5 metres down into the shaft tank and the downstream sewer, which measured 6 metres deep. The UltraTWIN controller offered twin-channel ultrasonic measurement. It could combine applications. Each channel was user-configurable to operate independently. It allowed for different controls for a full-function

open channel flow monitor, a pump control system, or as a level and volume monitoring unit for liquids or solids, calculating volumes and providing alarms. “The Pulsar Measurement products are always critical to the operation/ installation,” said David Greaves, Mechanical Engineer, nmcn plc. “Our engineers are experienced with the products, and someone is always on hand should we ever encounter any issues.” What do the Pulsar Measurement products do? Pre-set levels are built into the controller. Once these levels are reached, it triggers a relay in the panel, which starts the pump. Once it has reached the stop level,

another relay is activated, which stops the pump. In heavy rainfall conditions, the water levels in the sewer can rise significantly. In such a situation, a pre-set weir is breached upstream, and the flow cascades via a section of stainless-steel pipework into the new shaft. Once the main sewer level has dropped sufficiently, it sends a signal back to Pulsar Measurement’s UltraTWIN controller. The controller is in the panel, which will start the ejector pump to agitate the solids. It will then start a duty pump that empties the shaft. The dB10 within the shaft constantly monitors the water level as it rises or falls. Once the level has reached the pre-set pump stop level, the duty pump is automatically switched off, and the water will be returned to the sewer. Without monitoring the main sewer level downstream, the pumps may discharge early into the trunk sewer, causing it to surcharge and likely flood at its lowest point. “The Pulsar Measurement products are always critical to the operation/ installation,” said Greaves. “Our engineers are experienced with the products, and someone is always on hand should we ever encounter any issues.” For more information, visit pulsarmeasurement.com

FOCUS Leak Detection

Tech solutions for leak detection Xylem has been at the forefront of leak detection – its systems incorporate an array of technologies to support water utilities. XYLEM HAS DEVELOPED a range of leak detection systems designed to pick up and locate leaks within a pipe network. Kevin He, the Senior Practice Solutions Architect (Design Intelligence Solutions, Emerging Markets), has spoken about how the company’s range of solutions is providing new opportunities for water utilities worldwide. “Xylem’s leak detection systems

combine network sensing technologies with advanced algorithms and machine learning models to detect leaks,” He said. “We use techniques like pressure transient, exception, and acoustic energy monitoring. This monitoring system is now integrated into an advanced water management platform called Xylem Vue Powered by GoAigua. It unifies information

across data silos to provide a holistic view of all processes and infrastructure across the entire water cycle. It can generate insights and identify potential leaks from the customer’s premise to the distribution and supply network.” Xylem’s experience in this field has seen its systems implemented in many countries. Of note is the installation of 1800 Xylem sensors by Air Selangor, Malaysia’s biggest water services provider. It provides safe and drinkable water to about 8.4 million consumers in Selangor, Kuala Lumpur, and Putrajaya. “Those sensors were installed in 2017/18,” He said. “Air Selangor has been using the Xylem sensors to monitor over 6,000 km of their trunk main network. Since installing the sensors, the system has identified hundreds of pressure transients, bursts, and leaks in near real-time.” IoT and big data Xylem has invested in the Internet of Things (IoT) devices. That’s how the sensors connect and provide information to the customer. “Xylem can utilise the flow meters, customer meters and pressure sensors to calculate the performance efficiency of the networks,” said He. “This then tells the utility where they need to implement field intervention works, what those works need to be, and when they need to be done by putting an order of priority to the areas. Also, noise loggers can help pinpoint where the leak is located.” With all the information from flow meters, customer meters, and pressure sensors, it’s vital that the data can be read and interpreted in a way that supports the water utility. Xylem is ahead of the game when it comes to that, following its partnership with Idrica. “Xylem Vue powered by GoAigua is

a multi-faceted data agnostic digital platform that provides actionable insights into the asset performance of the utility,” he said. “Artificial Intelligence (AI) allows big data to improve network management.” He cites how water utilities traditionally recorded data at 15-minute intervals, representing a maximum of 96 daily readings. Xylem’s pressure transient monitoring system records up to 256 readings per second. That means it is now possible to handle larger volumes of data. This big data analysis provides better granularity for water network oversight.

Looking across the business Many utilities and local councils across Australia are investigating the digitisation of their water networks. Such a project involves the entire business, as it can impact every aspect of the business. “Leakage management is a multifunctional effort for water utilities requiring input from many functions,”

A user-friendly interface ensures that anyone can find the information that they need. Image: Xylem

said He. “It includes the non-revenue water team, field operations, engineering, IT, customer service and metering. As such, designing and configuring a leak detection system requires all the stakeholder groups to align their understanding of water efficiency and data insights.” That also means sharing data. One problem impacting businesses is the

tendency to keep dialogue for their own department rather than sharing it. This is called data siloing and can impinge on the effectiveness of any digitalisation project. “If departments within a business adopt a siloed mentality, it prevents data from being shared across the business,” he said. “It often prevents businesses from identifying the root cause of an issue. That means more time and money having to be spent to resolve the issue.” In He’s experience, data silos often appear when different vendors provide individual data services, not interacting with each other. It results in multiple platforms being used by the employees, reducing efficiency, and increasing the risk of mistakes. “Having a single platform to manage all information can bring separate and seemingly unrelated data streams together,” He said. “This allows cross-parameter analysis, which can deliver previously unidentified benefits. Digitisation all-encompassing He firmly believes in supporting the digitisation of water authorities and local councils. At the same time, such groups must understand the goals of digitisation and how to monitor the data entering the system. “The first step on the digitalisation journey is the setting up of an overall monitoring platform,” he said. “Subsequently, sectorising the network enables the utility to monitor its performance in more detail. It is important to include leak detection systems in a water utility’s overall digital transformation strategy. Otherwise, the operator could be left with several independent systems that can’t be integrated, and information ends up in data silos.” Being proactive is a fundamental

component of any digitisation project. He recognises that there are many operational improvement opportunities once the data flow starts coming in. “Tracking the data from sensors enables early identification of decreasing network performance,” said He. “However, live alerts and alarms from sensors linked to the digital platform enable the identification of the root cause of the alarm. The utility can send its field teams to the cause, saving time, effort, and money.” This is why the Xylem Vue Powered by GoAigua can combine alarms into clusters. There’s no point in sending individual alarms to system operators when a cluster of alarms can provide more accurate information. It’s also why clusters work better with big data. “It is impossible for human operators to monitor large volumes of information in near real-time in an era of big data,” He said. “It is essential that leak detection systems have automated analysis which can issue alerts and notifications to allow operators to respond effectively.”

Artificial intelligence and the future Artificial intelligence (AI) is changing almost every industry across the globe. Its use in the water industry has created many opportunities for improvement. “AI has brought and will bring further improvements in data analysis capability and accurate reporting of changes in operational performance,” said He. “Providing an intelligent eye on asset performance will enable utilities to increase their proactive network management capability and reduce their reactivebased event resolution process.” The impact of these intelligent systems is helping reduce the volume of water lost through leakage. The future remains bright for the water industry and the role of AI in detecting leaks. “The volume depends on how long it takes to be aware of a leak, locate it, and repair it,” He said. “AI will play a major role in improving the efficiency of utilities to reduce the length of time of each of these factors.” For more information, visit www.xylem.com

FOCUS The Future

Better together, into the future VicWater had an incredible 2023, with many highlights. Under the leadership of CEO Jo Lim and Chair David Middleton, VicWater is looking forward to a positive 2024. AS THE LEADING advocate for Victorian water businesses, VicWater continues to support a range of activities for its members. VicWater Chair David Middleton believes that 2023 was a transition year for VicWater in several ways. “The new five-year strategic plan that we rolled out in July was probably the most significant highlight for me,” Middleton said. “Jo led the engagement with the Board and the members, which has framed the next five years. It’s shown where we want to take VicWater in the next five years and the benefits to our members.” The other aspect that Middleton believes has been transforming VicWater is the closer integration of Intelligent Water Networks (IWN). “It’s been a positive step in the right direction from a governance and oversight level,” he said. VicWater CEO Jo Lim agreed with

Middleton about integrating IWN with VicWater and its members. “We have already seen some benefits arise from the trials through working with vendors,” Lim said. “We’ve been connecting the vendors with regulators and government departments. The goal is to facilitate the adoption of different pilot projects that IWN is operating.” She also highlighted the successful events during 2023, including the May People Summit and the September Annual Conference. “We have had a lot of really positive feedback from attendees,” she said. “We’ve also seen increased industry sponsorship and engagement from both events. We’ve also been running our Director Masterclass program with the Monash Sustainable Development Institute (MSDI). After running it in March and May, we’ll start again in February.”

Working together That integrative and collaborative discussion has extended to national programs and partnerships. That includes supporting WaterAble and welcoming guests from interstate to its conferences. “We’ve opened up the WaterAble partnership to interstate utilities,” said Lim. “So far, Sydney Water and Seqwater have both signed up. That collaboration is extending beyond our borders. We’ve also seen Busselton Water and Aqwest attend our Annual Conference. It exemplifies how VicWater extends its reach beyond the Victorian borders.” VicWater also works closely with the national associations. That includes groups like the Australian Water Association (AWA), the Water Industry Operators Association of Australia (WIOA) and the Water Services Association of Australia (WSAA). “We are always looking for those opportunities to work on specific things where it makes sense for the national bodies to take the lead,” she said. “We’re mindful that our focus should be on our members in the

Victorian water sector.” Middleton agreed with Lim, pointing out that at a strategic level, VicWater can take the lead from a national standpoint where necessary. “At the moment, we are looking at things that support our members,” he said. “VicWater does not need to get involved in everything. It’s about ensuring we provide our members the best possible service.” Better relationships As an advocacy leader, VicWater prides itself on collaborating with its members and the regulatory agencies they report to. The Department of Energy, Environment and Climate Action (DEECA) has provided funding for VicWater, and the two are working together on projects in key areas. “One example is the work we are doing on governance,” said Lim. “We have run training for corporate secretaries. There’s also the Director

Development Forum that VicWater is running in partnership with DEECA and Vic Catchments, which benefits our members.” Other projects focus on cybersecurity, the circular economy, and the environment. Of note are the Insight Program, the executive leadership program for women in water, and the Water Minister’s Climate Innovation Challenge. “These are programs that directly benefit our members,” she said. “But it’s more than just funding. We’ve been working on enhancing our broader relationship with key regulators. That includes the Environmental Protection Authority (EPA), the Essential Services Commission (ESC), the Department of Health, and the Department of Treasury and Finance.” Middleton looked at the private sector partners involved in what VicWater does. “We have a lot of support from

across the industry,” he said. “I think there’s recognition of a strong capability uplift occurring within VicWater. It’s an opportunity for us to provide these benefits to our members through partnerships with government and industry.” Looking into 2024 That role of connecting the Victorian water authorities has lain with VicWater for several years. One thing that has arisen from all the authorities coming together is the willingness to share knowledge. “Every time we meet, whether it’s the Managing Directors Forum or the Chairs Forum, we learn something new about what people are doing,” Middleton said. “It’s that cross-collaboration and capability uplift that is built into our motto of Better Together.” Lim agreed with the sentiment around sector cross-collaboration. She pointed out significant industry

issues, including climate change and net zero. “Working out how the industry will get to net zero is an issue that we are all grappling with,” she said. “The Victorian water sector is due to reach its 100 per cent renewable energy target by 2025. However, getting to net zero is a big challenge for us all. Some members need to reach this by 2030 and others by 2035 under the current statement of obligations. We are working with our members and communicating with the state government to ensure those expectations can be met.” Remaining financially stable is an ongoing challenge for the Victorian water industry. The ability to provide worldclass service to its customers in a heavily price-regulated environment pushes the boundaries of financial sustainability. “I think we’ve all agreed that we do not want to be in the position of the UK water industry at the moment,” Lim said. Plans for 2024 Lim believes that there is a lot of potential for VicWater in 2024. The biggest project it has been working on is helping its members meet net zero through carbon offsets.

“While our members are primarily focused on reducing emissions, we know that carbon offsets are going to be part of the solution,” she said. “We’ve been working with our members for two years on a project to unite them into a single body to access the carbon offsets market. It’s been an incredibly complex project dealing with an evolving market, subject to state and federal changes.” The other major project for VicWater in 2024 is developing a training academy where all water corporations can participate. Lim pointed out that this has arisen from labour shortages and a need for more training providers for water operators. “We initially looked at how to address that particular problem and got some support from the Victorian Skills Authority to kickstart the project,” she said. “That’s grown significantly beyond what we originally thought. We are looking at how utilities can access all sorts of training, not just water operations. “It’s an example of coming together and being Better Together.” For more information, visit vicwater.org.au

Unlocking the future of the water sector SUEZ is tackling challenges such as climate, water scarcity, water security, ageing infrastructure and water quality head-on, together with the industry and its clients. REFLECTING ON 2023, SUEZ Australia and New Zealand remains a steadfast player in the water sector. At the heart of this journey is the company’s commitment to being the trusted partner for circular solutions in water, and the role of its operations and delivery is the linchpin for shaping a sustainable future. It’s why people like SUEZ ANZ’s Vice President of Operations and Delivery, Mark Lautre, are focusing on a range of operational deliverables when it comes to shaping the circular economy for a sustainable future. Adapting to the thirst of tomorrow Water scarcity, exacerbated by climate change, is reshaping

how society approaches water management. As populations surge and environmental stressors intensify, the demand for efficient operations and delivery systems becomes non-negotiable. “Effective operations and delivery are not just about supplying water; they are about doing so reliably and sustainably,” said Lautre. In an era where droughts become more frequent and severe, the impact of operations is felt acutely. “We are witnessing a paradigm shift in how we view water scarcity,” he said. “Operations must adapt to these changing dynamics, optimising processes to ensure efficiency.” The traditional view of water scarcity as a localised and

temporary problem is evolving into recognising its systemic nature and long-term implications. The shift involves embracing a proactive, holistic, and collaborative approach to water management, considering the complex interplay of factors contributing to scarcity. Technological innovations, smart management practices, and datadriven decision-making can enhance the efficiency of water delivery systems, minimising waste and ensuring equitable access. Navigating the waters of quality Water quality also poses a challenge, influenced by factors like pollution from weather conditions and sectors like agriculture and manufacturing. Australia’s floods have added to this. As the floodwaters inundate water bodies, they transport pollutants, leading to increased levels of contaminants in rivers and reservoirs. As the raw water quality faces disruptions, water utilities are compelled to innovate and invest in strategies that mitigate the immediate impacts and enhance the long-term resilience of water treatment systems. Operations and delivery play a pivotal role in addressing water quality challenges. Lautre emphasises the need for innovation and collaboration.

INSIDE WATER January/February 2024

“Our approach is proactive,” he said. “We invest in strategies that not only mitigate immediate water quality impacts but also fortify the long-term resilience of our treatment systems. The quality of water we deliver directly reflects our commitment to the communities we serve. It’s not just a matter of compliance; it’s about exceeding expectations,” he says. The challenges and opportunities ahead In charting the course for the water sector’s future, Lautre envisions a transformative decade marked by strategic investments, operational excellence, and the strength of collaborative partnerships. The industry challenges necessitate a proactive, solution-driven focus with a central emphasis on operations, delivery, and the forging of strategic alliances. “Investments in the sector must not only be substantial but strategically aligned with sustainable solutions,” Lautre said. Leveraging SUEZ’s global experience, he advocates for

perspectives beyond existing frameworks, ensuring that investments yield the most effective and sustainable outcomes. Effective project management can also benefit from global technology, know-how, innovation, and competitive drive. Working together, these individual aspects can work towards achieving the best outcome. Lautre also states that driving efficiencies within businesses is vital in enabling greater investment affordability. “At the same time, there’s a need to adapt our operations and delivery frameworks to meet changing service standards and customer expectations,” he said. “This operational challenge creates a strategic space for SUEZ to use its digital and operational teams to strengthen partnerships with utilities and the industry while challenging operational benchmarks.” Innovation and resilience for tomorrow At the heart of SUEZ’s operations is a commitment to being the trusted partner for circular solutions in water.

Understanding water scarcity and how to provide plenty of potable water are twinned challenges that SUEZ ANZ is focusing on. Image: SUEZ

Lautre underscores this philosophy. “We go beyond mere delivery; we are stewards of water resources,” he said. “We aim to set industry standards for operational excellence, delivery efficiency, environmental sustainability, and community engagement. We’re not just meeting the demands of today but anticipating those of tomorrow.” As urbanisation reshapes the industry landscape, operations must strategically evolve. “Urbanisation intensifies pressure on water resources and infrastructure,” said Lautre. “Our task is to navigate this escalating demand through strategic planning, requiring innovative and resilient approaches in our operations.” In the face of challenges, the imperative is to unlock growth opportunities through collaboration and innovation. SUEZ assumes a leadership role in contributing to dialogues and delivering essential water services that create a sustainable water future. For more information, visit www.suez.com.au

Who won the Water Minister’s Climate Innovation Challenge? The 2023 Water Minister’s Climate Innovation Challenge award ceremony was held on Tuesday, 5 December, at the headquarters of Melbourne Water. It was an opportunity for water authorities across Victoria to showcase how they will reduce their impact on the climate in the future. THE WATER MINISTER’S Climate Innovation Challenge is a unique opportunity for water corporations. It seeks to demonstrate the industry’s commitment towards creating positive outcomes in the face of climate challenges in a collective effort to help strengthen Victoria’s climate resilience and shape the water industry’s future. Intelligent Water Networks (IWN) was entrusted by the Hon. Harriet Shing MP, Minister for Water, and collaborated with the Department of Energy, Environment and Climate Action (DEECA).The challenge will provide funding to the winning entrants, with a total funding pool of $135,000 from both the Minister’s office through DEECA and IWN, and a further $50,000 from DEECA to support a feasability study.

“Today’s event is a celebration of all the hard work and focus of these teams, from across our sector,” said IWN Program Director Jason Cotton. “These are teams of people who are dedicated to making a positive and lasting impact on the climate.” Thirteen submissions were made to the Climate Innovation Challenge, and six progressed to the final stage. Finalists for the Water Minister’s Climate Innovation Challenge Grampians Wimmera Mallee Water (GWMWater) GWMWater was represented by Will Taylor, an energy engineer. GWMWater’s submission was titled The Donald Community Energy Project. It was an opportunity for the water authority to establish a community-based renewable energy

generation and storage “farm” and sell electricity back to the community. Its proposal sought to develop the community business model to provide up to 70 per cent of the electricity needs of the town of Donald in the northwest of Victoria. “Donald currently offsets 1343 tons of carbon emissions through embedded solar,” said Taylor. “We could more than double that figure.” Central Highlands Water (CHW) Carsten Berberich is the Head of Environmental Services at CHW and presented the proposal. CHW wanted to put together a study focused on supporting industry and jobs by providing high-quality energy. He argued that Ballarat has considerable opportunities to utilise hydrogen and reduce natural gas use, given the development of opportunities for supply chain resilience. His study would support the reduction of greenhouse gas emissions, help industries transition away from natural gas, improve the sustainability of water management, and investigate new uses for hydrogen.

Yarra Valley Water (YVW), Barwon Water, North East Water (NEWater) This combined project was titled “Meta-analysis of low carbon cement alternatives for water industry applications.” Dr Lisa Ehrenfried (YVW), Hayley Vinden (Barwon Water) and Dr Jill Fagan (North East Water) presented their project to the ceremony. They focused on how to utilise lowcarbon cement alternatives in the construction of new facilities. “Cement generates about 8 per

cent of global carbon emissions,” said Ehrenfried. “As a country, it would have the third largest carbon footprint in the world.” The group estimated that its project would take the equivalent of 25,300 cars off the road within five years. The trio pointed to their preparatory work. They also said they would be ready to implement much of the project immediately if they received funding from the Water Minister’s Climate Innovation Challenge.

Barwon Water Emma McKinnon is the circular economy project advisor for Barwon Water. She presented a project that would recover the majority of cellulose from wastewater. McKinnon pointed out that Australians use an average of 88 rolls of toilet paper annually, totalling more than 7000 rolls over a life time. This represents about 1.5 million trees falling every year. Citing existing technology in the Netherlands, Barwon Water wanted to conduct a feasibility study, with the goal of preventing up to 2.5 tonnes of carbon emissions with every tonne of upcycled cellulose from wastewater. It will include a technical assessment, a financial assessment, market research, and an environmental impact assessment on recovering the cellulose. Greater Western Water (GWW) Brock Tunnicliffe is a technical officer at GWW. He spoke about how drone technology could be used to elevate environmental stewardship. It came about by finding a lack of spatial data in two and three dimensions. The absence of data meant that managing

environmental projects could be more challenging. The project aimed to implement drone technology to gather better data while understanding the business requirements for such a project. Tunnicliffe argued that there would be reductions in carbon emissions, improved planning, and improved condition monitoring. “Additional funding would allow GWW to accelerate and expand its drone program,” Tunnicliffe said. “We would aim to enter into partnerships to provide more and better data.” South East Water (SEW) Joel Segal presented as a treatment and resource recovery planning manager for SEW. The project focused on increasing the industry’s understanding of emissions. He looked at aerobic digesters’ role in emitting nitrous oxide, a gas with nearly 300 times more climate impact than carbon dioxide. By using real-time data and building calibrated models, the project aims to monitor the output of emissions from an aerobic digester. This shift to informed, data-driven decisions will provide a model that serves to reduce the sector’s environmental impact.

SEW is already working with the University of Queensland on this research, and hopes to develop more partnerships with consultants and subject matter experts. The results of the Water Minister’s Climate Innovation Challenge The Hon. Harriet Shing MP, Water Minister, provided a video message to the ceremony. There were two winners of the Climate Innovation Challenge. The joint project between Yarra Valley Water, Barwon Water, and North East Water (received their requested $20,000) was joined by Barwon Water (received their requested $30,000) as the winners. The runnerup was GWMWater, who received their total project funding request of $85,000. South East Water received a special commendation. The Minister announced that DEECA and IWN would work directly with South East Water to fund and run their project.

Water shortages worldwide Access to water is an ongoing issue for the entire world. Having the proper methods to minimise water shortages and their impacts is critical for the reliability and safety of the water supply of the global population. ACCORDING TO A report published recently by the World Economic Forum in conjunction with the World Resources Institute, at least 50 per cent of the world’s population live under highly water-stressed conditions for at least one month of the year. That represents about four billion people. The report showed that 25 countries are particularly vulnerable, mainly in the Middle East and North Africa. These are places where low rainfall is experienced against a background of high demand from domestic, agricultural, and industrial use. In these regions, 83 per cent of the population is exposed to high water stress. Some South Asian countries are in similar situations, with 74 per cent of the population being exposed. Even a short-term drought puts

these places in danger of running out of water. The situation is getting progressively worse. By 2050, the report estimates that at least an additional 1 billion people will live with high water stress. As most of the vulnerable countries experience relatively hot climates, evaporation from open water bodies is a significant cause of water loss, but its impact isn’t generally appreciated. As a rough rule of thumb, every single degree increase in average daily temperature will increase daily evaporation by about 2 millimetres. For example, if the average daily temperature increases from 28 to 33 degrees Celsius, daily evaporation will increase from about 5 to 10 millimetres. This may not seem to be much, but it equates to a loss of 10 litres for every square metre

The Aquatain AMF film reduces the surface tension of the water, preventing the immature mosquito larvae from attaching to the surface to breathe. This causes them to drown. Malaria kills more than 700,000 people in Africa each year, and mining companies recognise their responsibility to protect their employees and families from disease.

How can nature improve wastewater management? A lot has been said about rewilding waterways and urban creeks. However, Hydroflux has found inspiration in nature to partner with Organica Water to provide a product that implements bio-films. THE ORGANICA FOOD Chain Reactor (FCR) is a compact and seamlessly integrated wastewater treatment facility that minimises wastewater treatment’s technological, architectural, and environmental impact in residential and commercial settings. Organica’s FCR has been validated by over 120 projects worldwide, showcasing the practical advantages of the technology. “These facilities are designed for implementation in diverse climates,” said Hydroflux director Andrew Miley. “They can handle volumes ranging from 1000 to 200,000 cubic metres per day.” Integrated Fixed Film Activated Sludge Plants (IFAS) rely on a media where biofilm is grown, resulting in a compact footprint as most of the biomass is fixed to a high surface area instead of being suspended. The development of a variation of

IFAS Plants by Organica Water has been to combine naturally occurring plants with engineered media. Simply put, a botanical garden is placed on top of the IFAS reactors, with the plant roots penetrating the reactors. “The interaction of enzymes and various organic acids from the plant roots to the bio-media creates a diverse biology,” Miley said. “It leads to increased process stability, less sludge production, and lower energy demand than conventional activated sludge plants. The sewage treatment plant looks like a botanical garden.” Bio-film technology Bio-film technology in wastewater treatment has been available since the 1970s as moving bed biofilm reactor (MBBR) systems or IFAS. In general, most of the developments in this field relate to increased surface area, scouring and bio-film growth. Generally, the media used in either

MBBR or IFAS is a non-metallic surface. Both systems provide benefits such as reduced reactor size, high total available biomass inventory, high tolerance against biomass washout and simultaneous nitrification-denitrification within the biofilm layer. Organica’s FCR combines naturally occurring plants with an IFAS-based process. A greenhouse or shaded structure typically houses the process, creating an aesthetically pleasing treatment system. The FCR is generally configured as a continuous multistage cascade process with an anoxic zone and internal recycling from the last stage as part of the nitrogen removal loop. Benefits of bio-films The multistage cascade FCR provides several operational benefits. That includes the independent development of biomass and ecology within each stage. It also features an increase in the diversity of biomass speciation. That comes from the interaction between the plants and the biomass. “The bio-film growth results in a much higher total biomass inventory,” said Miley. “We have also seen higher sludge retention time and a reduced biomass yield. That comes from the higher sludge retention time.” The lower free MLSS means the phase separation step post-FCR can

be designed with a lower loading. Rather than using secondary clarifiers, phase separation can occur in a horizontal disc filter, which has a tenth of the footprint of a conventional clarifier. In addition, the lower MLSS results in a higher diffuser alpha factor, meaning that less air is required to provide the process oxygen needed, thus a lower energy demand. “We’ve also found that there is not as much odour around the plant,” he said. “There’s also no need to return activated sludge (RAS) in the process design.” Diversity of biomass speciation results in adaptive ecologies forming in each FCR stage. As opposed to 300 to 400 species commonly present in activated sludge plants, the FCR exhibits up to 3000. This diversity creates a stable process, which is tolerant to shock loads. In the last stage, the presence of eukaryotes results in the consumption of decayed bacteria. Operating data has demonstrated the robustness of the FCR systems, as well as consistent effluent quality. The discharge quality that can be achieved can be designed to match any conventional activated or MBR process.

The total observed biomass within the FCR system is typically 16,000 milligrams per litre, three to four times that of conventional systems. Aesthetics The FCR can be housed within a greenhouse or shading structure, resulting in a wastewater treatment plant resembling a garden or greenhouse facility, with low odour emissions and an aesthetically pleasing look. Due to this unique feature, in some installations, buffer zones around the treatment plant have been reduced from 350 to 50 metres. This frees up additional land for development and providing a net positive attitude from local communities. Bio-film technology provides several advantages around footprints, biomass inventory, capital, and operational cost savings. The natural plants do not treat the wastewater but provide nutrients, organic acids, and enzymes, creating a diverse biology within the plant roots and IFAS modules. A denser biofilm is produced compared to other IFAS systems or MBBR processes. A reduced footprint can be achieved with an observed total

biomass concentration three times that of conventional systems. Savings in energy demand and sludge disposal are two other benefits of the process, particularly over MBR-based systems with similar space-saving features. Full-scale installations as large as 80 MLD have demonstrated the technology’s application within the municipal and industrial wastewater fields. The aesthetically pleasing look of the Organica FCR has changed the local community’s attitude towards wastewater treatment. It has provided a place for communities to interact positively with the process. As rapid urban growth continues in many cities worldwide, this technology has demonstrated its use as a decentralised facility that can be constructed in the middle of a dense urban landscape. It can relieve the load on existing sewer systems and enable water reclamation in these environments.

FOCUS The last word

Why rain smells so good To finish each issue, we aim to look at the lighter side of water and water-related issues. If you’ve seen an amusing story, let us know so we can consider it for the next issue. THERE ARE MANY wordsmiths among us, but more importantly, more people recognise the smell of rain. Have you ever wondered what that smell is called? The word for that smell is petrichor, first described scientifically by two Australian researchers. CSIRO researchers Isabel Bear and Dick Thomas coined the term “petrichor” in a March 1964 paper that was published in the esteemed scientific journal Nature. The term was previously known as argillaceous odour. The word is constructed from Ancient Greek πέτρα (pétra) ‘rock’, or πέτρος (pétros) ‘stone’, and ἰχώρ (ikhṓr). The latter is the ethereal fluid that is the blood of the gods in Greek mythology. Despite alien, devilish or demonic blood connotations, it has also been known as an antiquated term for a watery discharge (ewww) from a wound or ulcer. That was usually associated with an unpleasant or

fetid smell. Later research suggests that this was plasma, a vital fluid for people’s health. It was earlier observed in the 1890s by Thomas Lambe Phipson. He referred to his old notes and theorised that the smell was due to the presence of organic substances closely related to the essential oils of plants. Phipson also believes that the substances were absorbed into the soil’s pores, only to be released when displaced by rain. He tried to isolate the chemicals and thought they were similar or identical to cedar oil. So what is petrichor? It’s an oil that certain plants exude during dry periods. Clay-based soils and rocks absorb that oil. When it rains, the oil is released into the air as an aerosol. That’s because when a raindrop hits a porous surface, the air in the pores creates tiny bubbles. They float to the surface and release the aerosols. That’s not the only aerosol that is released. An organic compound

called geosmin is also set free. Geosmin, along with another compound, accounts for most biologically caused taste and odour outbreaks in drinking water. While the phrase outbreak may sound scary, it’s a widespread occurrence. These two compounds are released into the air and have a distinct earthy smell. Sometimes, ozone can also be smelled, but that’s more the case if there have been lightning strikes in the local area. Raindrops that move at a slower rate tend to produce more aerosols. This explains why petrichor is more common after light rains. The question is, why can humans smell these compounds? It turns out that the human nose is extremely sensitive to geosmin. We can detect it at concentrations as low as 0.4 parts per billion (ppb). It appears that humans have evolved the ability to smell petrichor, as our ancestors might have relied on the smell of rainy weather to survive.
