Chairperson's Report Alison Waters

Welcome to the summer edition of The Overflow and Happy New Year to all.

Hope you had some down time over the Xmas/New Year period.

We had our Annual regional meeting on 21 November, and I’m pleased to advise that I was re-nominated for Regional Chair. The other members elected to the WA Regional Committee include Mark Davies (Vice Chair), Andrew Ogden (Secretary), and Daniel Rose (Treasurer).

Several subcommittees have successfully nominated their chairs, including Jason Rothery (Waterwise), Mark Davies (Members Interest Technical), Paul Willmott (Training). We also have the Rural and Training Committees. Thank

you to everyone who has nominated and contributed their time and expertise to these committees — it is greatly appreciated. We look forward to continuing our efforts throughout 2025. If you're interested in joining a committee or would like more information, please don’t hesitate to contact either myself or Rebecca New. We are working alongside the national office to provide partnership submission for a federal training grant. The committee has provided in kind support including work placement, industry, training, knowledge ectera. Stay tuned for future editions to see if we were successful in attaining the grant.

There has been an update to the National Water agreement with the draft agreement published in December.

More information is available at The new National Water Agreement - DCCEEW. The Australian Water Association has announced a Water Efficiency Conference to explore the next generation of water efficiency in Melbourne in September.

The Overflow | Summer 2024/25

From the CEO Dave Cameron

Greetings all and Happy New Year!

We’ve seen some pretty strong indicators of how challenging 2024 was for our industry with decreases in training enrolments, and a general decline in availability for things like regional activities. For the first time, for example, the WA annual regional meeting had to be cancelled due to low numbers. On top of that there are constant reports of staffing challenges which have impacted Irrigation Australia directly as well with a couple of recruits for the WA office resigning after very short stints. There is clearly no shortage of work out there.

Every challenge creates an opportunity, and it all gives us a chance to critically review how we do things and the WA committee has made some tweaks to meetings. We are also very proud of the changes made at our RTO to better support students and employers, as well as our quality trainers based in the region led by Paul Willmott, and look forward to getting as many new students as possible this year, as well as introduce some new programs. Paul has now delivered the Certified Irrigation Installer course to the first student cohort with rave reviews, and we see this particular skill set (part of the larger Certificate III in Irrigation Technology) as a critical tool in addressing skilling and attraction challenges.

With the support of the regional committee we were able to pull together

a major federal funding application for the region in November. While it could be a couple of months before we find out the result (and it might not work), it’s worth talking about the intent because the underpinning issues aren’t going away any time soon and as an industry we need to look for every opportunity to try different things to address them.

The Building Womens’ Careers program is a $60M+ one-off investment by the federal government which will fund partnership projects “to advance structural and cultural change to improve womens’ access to flexible, safe and inclusive training and work opportunities in the key male-dominated industries.”

Our application is based around the challenges in an ageing workforce and generally attracting and retaining staff in urban irrigation/ landscape construction – something which is perhaps heightened in WA thanks to the need to compete with the resources sectors for skills.

It proposes the identification of industry mentors – both male and female – to support the introduction of 60+ new young women into irrigation over the 3 year life of the program. If successful it would not specifically fund employment, but is fundamentally intended to drive a stronger approach to diversity in the industry in the region, and would cover as a minimum the Certified Irrigation Installer skill set for participants.

Irrigation Australia hosts a number of digital platforms that attract a broad audience from the entire supply chain of the irrigation industry including retailers, installers/contractors, landscapers, irrigation professionals, manufacturers, primary producers, students, scientists, researchers and state/local government agencies.

The Advantages of Digital Publications • Digital editions available to readers immediately after publishing • Available to access anywhere at any time • Live links to websites, emails and phone numbers from the articles or adverts • Creates options to use video advertisements • Precise analytics on distribution and readership • Digital publications will be widely distributed electronically using all Irrigation Australia online platforms (ee-news, Social Media, Websites, EDM’s, etc..)

Irrigation Australia released its new careers website last year and new and refined content is being continuously added. We’ve started a webinar series with the support of the Australian Department of Employment and Workplace Relations with more to come in early 2025, have started building the profile of the industry through national resources including myfuture.edu.au and are aiming to see industry co-investment with a big focus on careers in 2025 through Irrigation Futures. I’m keen to hear from any members with a passion to help drive initiatives to help address our employment challenges – either through initiatives like the subject of the grant application or skills working groups we are aiming to establish soon.

Congratulations to Bec, our stakeholders and exhibitors for the August Waterwise Expo – at the time of writing, the event was almost fully subscribed and is shaping up to be a fantastic industry showcase.

Here’s to a prosperous 2025 for our members and the Association. My door is always open for new ideas and the region has a great track record of collaboration – I look forward to getting some new and innovative projects up this year to make a difference.

Dave Cameron Irrigation Australia Chief Executive Officer

Wooroloo Prison Farm Market Gardens Reticulation System An Industry-Driven Irrigation Solution The market gardens at Wooroloo Prison Farm are an integral part of the facility’s vocational training program and play a vital role in providing prisoners with valuable skills and work experience.

Wooroloo has been producing fresh fruit and vegetables for the prison kitchen since 2008 while offering prisoners the opportunity to earn a Certificate II in Horticulture.

land. However, as the area expanded to include protected cropping for hydroponic tomatoes, a redesign was needed. The key objective of the upgrade was to optimise water usage and ensure consistent production of high-quality crops, particularly tomatoes, year-round.

The initiative has grown significantly since its inception, and in response to increased demand, the irrigation system supporting the market garden has evolved to provide greater production.

The redesigned system incorporated inline drip irrigation for soil-grown vegetables, powered by a gravity-fed 50,000-litre tank. This low-tech and relatively low-cost solution was intended to improve efficiency, reduce water waste, and provide meaningful work training opportunities for prisoners.

Initially, the irrigation system used a traditional plastic sprinkler setup to irrigate 2,000 square meters of

Short-term benefits included better control over water distribution, improved plant growth, and increased crop

yields. Long-term benefits involve the creation of sustainable agricultural practices and continued job training for prisoners, alongside a steady supply of fresh produce for the prison kitchen.

The system's design focused on water conservation through the use of drip irrigation, which directly delivers water to plant roots, minimising evaporation.

The irrigation setup needed to meet budgetary requirements and be low maintenance and easy-care for the volunteer prisoner workforce learning new skills. To meet operational requirements of the prison farm, it was also essential to design the system for maximum reliability and efficiency during working hours.

The Overflow | Summer 2024/25

The irrigation system includes a 50mm supply line running 400 metres from an elevated 50,000-litre tank to various growing areas. Six separate zones, each requiring distinct watering schedules, are controlled by a Hunter ICC 8 Station Controller, which includes a 4-station expansion module.

The hydroponic tomato tunnel uses an ONGA pressure pump, a 4,000-litre tank, and 3 L/hr drippers with multiple watering times per day to meet seasonal and temperature needs. For in-ground crops, a Netafim Techline AS 3 LPH drip system with 30cm spacing is used to irrigate a diverse range of vegetables, including broccoli, tomatoes, and others.

What Has Been Grown: Crops, Yields, and Growth Insights The market gardens focus on growing a variety of crops, with broccoli being a seasonal favourite from March to September, and tomatoes are grown year-round in the hydroponic system. Other crops are rotated based on seasonal requirements, with a consistent watering and fertilising program ensuring steady growth. The use of straw for mulching and regular composting (20m3 produced annually) enhances soil health and yields.

10

The Overflow | Summer 2024/25

Through careful selection of crops suited to the season, the farm has been able to maintain high productivity levels.

However, the presence of the diamond back moth in spring means that broccoli production is limited to cooler months.

A key lesson learned was the importance of properly sequencing watering times across different zones to avoid pressure clashes. Early testing and scheduling adjustments ensured the system operated smoothly without overloading the pressure.

The irrigation system relies on several key components: •

Infield System: Netafim Techline AS 3 LPH drip lines, placed on the surface of the soil with 30cm spacing, cover the main growing areas.

•

Controller: The Hunter ICC-800PL unit controls irrigation for the entire farm, with one station dedicated to the hydroponic tomato system.

•

Pumps and Tanks: A gravity-fed 50,000-litre tank supplies water to soil crops, while a 4,000-litre tank with an ONGA pump handles the hydroponic system.

•

Bore: The water supply comes from the Kalgoorlie pipeline, with gravity feed from the elevated tank.

Regular maintenance is critical to the system's success.

Leaks, blocked drippers, and nutrient sludge build-up in the hydroponic system are common issues. Workers must frequently check for leaks, flush the hydroponic lines, and identify faulty joints in the reticulation cables. Occasional damage has been a challenge, making the selection of suitable workers and proper training crucial for the farm's success.

IN THE GARDEN WITH

The irrigation system was installed over several phases, with hand-trenching for all reticulation lines to a depth of 200mm. The supply line runs along an open rainwater drain system through the prison, ensuring minimal disruption to operations. Installation of the drip lines and wcontroller was completed in stages, with careful consideration of the unique needs of each crop zone.

The system's installation used a combination of methods.

The 50mm supply line was laid using directional drilling to minimise disruption, while manual excavation was used to install the drip lines. These methods ensured that the installation process was as efficient as possible, met the budget and workforce availability.

The most significant outcome of the new system is improved water efficiency. Direct water delivery to the plant roots has reduced evaporation and prevented damage from overheating. Additionally, the system’s design allows for diverse crops to be irrigated using the same infrastructure, making it both cost-effective and adaptable.

Additionally, there can be reduced personnel available at times to manage issues like power outages or pump failures. These challenges are mitigated through careful planning and by ensuring that critical tasks are performed during work hours.

A Memorable Visit from Costa Georgiadis A highlight for both staff and prisoners at Wooroloo Prison Farm was a recent visit from gardening superstar Costa Georgiadis. Costa took a tour of the Market Gardens, orchards, and landscaped grounds, and was thoroughly impressed by the operation.

His enthusiasm and down-to-earth approach were a hit with prisoners, who appreciated the opportunity to engage with him and ask questions about horticulture and sustainable gardening. For many, the chance to have a personal conversation with Costa meant a lot, providing a rare and motivational experience. Staff and prisoners alike are hopeful that Costa will return in the future—perhaps with his own TV crew in tow!

Looking ahead, the Market Gardens project is set to expand its operations with further irrigation system improvements, including the addition of more hydroponic tunnels to meet growing demand.

Plans for system upgrades will also focus on increasing automation to reduce the reliance on manual labour,

The Future of Irrigation: Automation and Innovation in the Gascoyne Irrigation Scheme Gascoyne Water Co-operative (GWC) in Western Australia recently embarked on a transformative journey to modernize its irrigation infrastructure.

The project, titled the Gascoyne Irrigation Scheme Augmentation and Modernisation (GISAM), was designed to future-proof the region’s water supply, ensuring it meets growing demands while maintaining equitable distribution for all its members. Central to this upgrade is the integration of cutting-edge automation technology provided by Aquamonix, a leader in telemetry and control systems.

With a focus on sustainability, efficiency, and long-term resilience, the GISAM project aimed to replace aging infrastructure and modernize the water distribution system for greater reliability. The introduction of automation and remote monitoring, through a sophisticated Gatekeeper telemetry and control system, marks a significant leap forward in irrigation management. This system is now responsible for operating 34 pumps across the bore field and 189 distribution points, incorporating a suite of innovative devices that offer unprecedented real-time control.

14

The Overflow | Summer 2024/25

Streamlining Irrigation with Telemetry and Control Aquamonix’s solution for GWC includes the deployment of Emflux Electromagnetic flowmeters, butterfly valve actuators, and Neo telemetry devices at each of the 189 distribution points. Together, these components allow for seamless, automated control of water flow, with real-time monitoring and adjustments to ensure that the system operates within optimal parameters. The integration of these devices into the GWC network enables a level of precision and responsiveness that was previously unattainable.

A key feature of the system is its ability to instantly detect disruptions and deviations from expected performance.

The system sends immediate alerts, which are crucial for managing the water supply in real-time and preventing inefficiencies or system failures. The graphical display on the SCADA system, uses multi coloured indicators to provide operators with a clear visual representation of the health of each bore. If an issue arises, operators are notified instantly via email or SMS, enabling swift action to resolve problems before they escalate.

system taking large amounts of water, this is exaggerated when a landholder with a small 50mm outlet has a neighbour with a larger 200mm outlet.

A key driver for pipeline automation is to overcome this constraint and provide equitable water supply for all landholders.

Equitability Through Automation and Pipelines The Gascoyne region, with its harsh, often arid conditions, stands to benefit enormously from the shift towards automated water distribution.

Automation not only improves operational efficiency but also

contributes to substantial water savings.

Pipeline systems while being superior to traditional channel-based systems, still face delivery constraints due to bottlenecks in the pipeline network.

During times of high demand this can result in a landholder receiving a trickle of water due to neighbours in the

LET’S START THE CONVERSATION TEXT OR CALL 0488 846 988 MON - FRI, 8AM -10PM AEST

In May 2023 an innovative design was created by Mark Davies (Aquamonix Business Manager) and Rod Sweetman (former GWC Chairman) to provide a system which monitors parameters across the pipeline to automatically adjusts inflow and outflows ensuring that all landholders can receive water on demand.

Key pressure locations and outlet flowrates are monitored in real time so that the system can respond rapidly to localised pressure reductions. If low system pressure is detected in an area of the pipe network during times of increased demand, groups of delivery points will partially close their valves ensuring that back pressure is maintained, and water is available for all members. Valves will automatically reopen to 100% when demand drops, and supply is available.

Member concerns around supply shutoff were addressed by ensuring that valves are unable to close more than 75% under operational conditions.

Due to the non-linear flow through a butterfly valve a position of 75% equates to 53% of maximum flow.

Therefore in periods of peak demand a landholder is still guaranteed delivery of water at a minimum of 53% of their maximum flowrate.

The Overflow | Summer 2024/25

With guaranteed supply of water throughout peak demand seasons, farmers can plant to schedule and adopt more efficient irrigation methods, increasing crop yields. The GWC’s new system empowers farmers to diversify their crops and irrigation techniques, supporting the region’s growing citrus and table grape industries.

durable and require far less maintenance than traditional open channels, ensuring the sustainability of the irrigation network for years to come. The ability to monitor and automate a pipeline as a contained system ensures that water is available on demand to landholders, maximising yields, efficiencies and profitability.

Remote Monitoring for Smarter Water Management

The transition to automated systems also opens up new possibilities for the region. As water management becomes more precise and less reliant on manual intervention, farmers can take full advantage of modern irrigation technologies. With the ability to change irrigation methods as needed, GWC members have the flexibility to optimise water use on their farms and adapt to changing agricultural needs.

In addition to its operational efficiencies, the new system also supports better tracking of water usage, ensuring that resources are distributed equitably among the coop's members. Each distribution point is equipped with a telemetry unit that is integrated with the flow meter, sending data back to the central system. This real-time data enables GWC to track consumption volumes and flow rates, providing a more accurate picture of each member’s water use.

As the GWC Board has explained, the new telemetry system allows for greater transparency and fairness in water distribution. By having instantaneous access to member water usage, GWC can assess how much water each member is consuming and provide accurate feedback to member relating to remaining seasonal allocations. The ability to monitor and adjust the system remotely also facilitates proactive management of the water supply, preventing over- or under-utilisation of resources.

A Vision for the Future While the initial investment in pipeline infrastructure and automation is significant, the long-term benefits are clear. Pipeline systems are more

Aquamonix’s role in the GISAM project highlights the growing importance of automation in modern irrigation systems.

With its advanced telemetry and control solutions, the company has helped GWC achieve a more efficient, sustainable, and equitable water distribution system, setting a new benchmark for irrigation practices in Australia.

As water scarcity becomes an increasing concern in many parts of the world, projects like the Gascoyne Irrigation Scheme Augmentation and Modernisation demonstrate the power of innovation and automation to improve water management. The future of irrigation is automated, and Aquamonix is at the forefront of this transformation, helping to shape a more sustainable and efficient agricultural landscape for generations to come.

‘Pollinator haven’ crowned City’s waterwise garden winner A ‘pollinator haven’ brimming with a cottage-style mix of natives, annuals and hardy exotic plants on a small residential verge in Southern River has won the City of Gosnells Sustainable Garden Competition.

Supported by The Retic and Landscape Shop in Southern River, the competition’s top three garden entries received prizes including $500 for first prize, $250 for second prize and $100 for third prize.

“It just shows that, even with a tiny space, you can still have a positive impact on the local environment.”

Mrs Clarke’s colourful compact garden caught the eye of Mayor Terresa Lynes and City of Gosnells Councillors who dropped by to do visual inspections of the top three garden entries before a winner was decided.

Mayor Lynes was impressed by Mrs Clarke’s verge garden, which attracts many local birds including magpies and willy wagtails.

“This garden has demonstrated how it is possible to create a beautiful verge garden on a smaller lot,” Mayor Lynes.

Homeowner and eager gardener Sarah Clarke, who moved into the property in 2020, initially installed lawn to the front verge. But she later realised that she wanted to create a more sustainable garden that not only attracted bees and wildlife such as birds and frogs, but also complemented the verge tree, an Agonis flexuosa, commonly known as a peppermint tree, which was planted by the City.

“Even though my front yard and verge is small, I've got so many pollinators, birds, and frogs visiting my garden,” Mrs Clarke said.

Southern River resident Sarah Clarke, pictured with City of Gosnells Mayor Terresa Lynes and Jason Rothery of The Retic and Landscape Shop has won the City’s Sustainable Garden competition.

“You can see the passion and dedication that has gone into establishing this garden, which is bursting with colour and fragrance and is also much-loved by the local wildlife – especially the bees!”

The garden of Southern River resident Kyle Wood placed second, with Swati Sankhla’s Canning Vale garden in third place.

The gardens were recognised for embracing sustainable waterwise practices and drawing inspiration from WA’s diverse native flora.

“The Sustainable Garden Competition was introduced in 2024 to encourage, support and promote the efforts of residents to plant and maintain sustainable gardens,” Mayor Lynes said.

“Residents were asked to submit pictures of their front gardens and verges and answer three short questions on garden design, maintenance and the benefits of their garden, to demonstrate the sustainability of their gardens.

“The entries we received were very inspiring and a great demonstration of what can be achieved when the City and residents work together towards a greener, more sustainable future.”

In response to the challenges of climate change, the City of Gosnells endorsed its first Sustainability Action Plan in 2023, followed by an Emissions Reduction Strategy in 2024.

These documents outlined the City’s plans to reduce energy consumption, switch to renewable energy sources and improve the natural environment.

Water security is an important element of enhancing the City’s natural environment and presents a challenging balance between reducing water consumption and ensuring green spaces receive adequate water to meet the community’s needs.

“The City started participating in the Waterwise Councils program in 2020, achieved Gold endorsement in 2023 and is now working toward Platinum status,” Mayor Lynes said.

“The City’s aquatic centre, Leisure World, reached Gold status in 2022.

“City staff have had success managing green spaces through hydro-zoning

and eco-zoning, which result in more efficient water use, as well as reduced mowing time.

“More efficient irrigation systems and pumps have also reduced energy use.”

Left: Demand Delivery’s team behind the Waterwise Forums held for local government, business and industry customers

The Waterwise Business Forum was opened by Water Corporation CEO Pat Donovan, who thanked business customers for using 148 billion litres less water since the Waterwise Business Program commenced in 2007.

Mr Donovan said ‘Our Waterwise programs go a long way to slowing down the demand for water as we continue to do all we can to keep pace with population growth, changing customer expectations and the everincreasing impacts of climate change.’

Making Waterwise waves Our efforts to be waterwise and drive climate resilience are having far reaching impacts, even as far as Europe!

Bringing together waterwise champions across local governments and businesses – Double Feature!

This spring Water Corporation held not one but two Waterwise Forums, highlighting the 2024 National Water Week theme ‘Accelerating Action’ and bringing together participants to network with peers and industry and to learn about the latest waterwise case studies, innovations, projects and initiatives.

Water Corporation’s General Manager Customer & Community Karen Willis opened the Waterwise Councils Forum, acknowledging the important role local government champions play in delivering waterwise solutions suited to the local context and aspirations of their communities.

Around 90 guests attended the forum and learnt about tree canopy resilience in a drying climate and strategies to combat the polyphagous shot-hole borer that is causing tree loss across Boorloo. Water Corporation staff

The Overflow | Summer 2024/25

provided guests with an overview of managed aquifer recharge and how we are using new technologies in leak detection, while presentations from industry covered tree canopy and the polyphagous shot-hole borer.

More than 70 guests attended the Waterwise Business Forum and learnt about topics such as garden design and the waterwise strategies adopted

by RAAFA’s Merriwa Estate, which saw them being awarded this year’s Platinum Waterwise Business of the Year.

“Our Waterwise partnerships help us to achieve our Thrive2035 goals, and our annual forums are important events in celebrating achievements by program participants and highlighting some of the latest innovations,” Water Efficiency Partnerships Coordinator Erin Vis said.

Why is this a big deal?

The congress is all about cutting-edge approaches to water system services, and Perth was recognised as a “best in class”. It’s no surprise that in WA we’ve faced the harsh reality of climate change faster than almost anywhere else in the world, but we have risen to meet this challenge and Perth has become an international example of what it means to be waterwise.

Travelling from Perth to Poland to showcase our leading water practices But Water Corporation is not just making waterwise waves in Perth, we’re going international!

The Corporation’s work using the Water Sensitive Cities Index framework and fostering collaboration across the

many organisations that shape our city has earned us recognition alongside Europe’s best – and guess what? Perth is leading the way!

Representatives of Perth headed to Poland in October, where they showcased Perth’s transformation into a waterwise city at an international congress.

The presentation highlighted Perth’s transition using the Water Sensitive Cities Index, which is a powerful benchmarking tool that has helped shape our journey towards a waterwise city. But improving our index score and making progress to becoming a truly Water Sensitive City cannot be done alone. Key actions that have helped improve Perth’s benchmarking score include improved cross-sector collaboration, waterwise education and reducing demand, increasing resource recovery and recycling of water, and transitioning to a cleaner energy future.

City of Joondalup a dual winner at the AIPH Green City Awards The City of Joondalup claimed two major awards at the 2024 International Association of Horticultural Producers (AIPH) World Green City Awards for its Climate Change Strategy. The City was announced as winner of the Living Green for Water category and the inaugural Youth Award.

Located in Perth, Western Australia, the City manages and cares for nearly 400 parks, natural areas and public open spaces essential to the wellbeing of its residents and wider community.

Situated within a global biodiversity hotspot with the highest concentration of rare and endangered species on the continent, already impacted by habitat fragmentation, and with Perth having the least tree canopy cover of all Australian capital cities, the City, its environment and its residents are vulnerable to the impacts of climate change.

The City is committed to building a more waterwise, liveable and resilient City, which is reflected in its response to climate change through the implementation of the Climate Change Strategy. The award-winning Strategy

26

The Overflow | Summer 2024/25

identifies corporate and community focused initiatives that aim to adapt and mitigate against the environmental impacts of climate change, rapid urbanisation and the increasing urban heat island effect.

Living Green for Water Award The AIPH Living Green for Water Award recognises Cities that are ensuring water resources are safeguarded and used wisely. The City aspires to reduce water usage, enhance green urban spaces and encourage community engagement through education to overcome climate change.

Above: The City of Joondalup received the Living Green for Water Award and Youth Award at the World Green City Awards.

The City has implemented several waterwise initiatives within its corporate operations and wider community to conserve and protect its precious water sources. These actions will ensure the City is better equipped and prepared to face climate change impacts and led to the City being internationally recognised at the AIPH Awards as a Living Green for Water City.

Lake Joondalup, Yellagonga Regional Park. Waterwise Park Redevelopment Projects

The Parks Redevelopment Program aims to reduce water usage by undertaking eco-zoning and hydrozoning in City parks.

Waterwise Park Redevelopment Projects The City implements detailed landscaping and irrigation designs to reduce irrigated areas in at least one park per year by implementing hydrozoning, eco-zoning and waterwise landscaping as part of the Parks Redevelopment Program.

Water consumption is reduced by creating hydro-zones to allow different watering rates to be applied and creating eco-zones where turfed areas are mulched in different areas of the park which further reduces water consumption.

The City’s Smart Control Irrigation System uses scientifically based evidence to control groundwater use in parks and sporting grounds across the City. The controllers automate the groundwater required based on evaporation rates and switch off the system when it rains which reduces the amount of groundwater the City uses for irrigation purposes.

The City’s Leafy City Program was launched in May 2017 with 6,300 trees planted to date. An additional 10,000 trees have been planted through the Winter Tree Planting Program over the past 4 years. The City’s Climate Change Strategy includes a target of planting a minimum of 1,000 trees per year.

As a result of its ongoing planting initiatives, canopy cover within the City has increased from 9% in 2014 to 12% in 2020. This will result in reduced water usage in the long-term by mitigating the urban heat island effect, improving the soil and filtering groundwater. The City is confident tree planting is having a positive impact along with community education and opportunities for residents to be active participants in urban greening.

Community Waterwise Programs As an endorsed Gold Waterwise Council, the City receives Water Corporation funding through the Waterwise Greening Scheme to implement initiatives such as the Waterwise Verge Rebate Program, Native Plant Giveaway and Waterwise Demonstration Gardens. The aim is to inspire and provide support for residents to create waterwise gardens and improve biodiversity across City suburbs.

The City implemented a Waterwise Verge Rebate Program in 2022/23 which provided the opportunity for the community to create their own waterwise verges and contribute to a greener, biodiverse and more inviting City that aligns with the City’s strategic goal of reducing the impacts of climate change.

On average, a redeveloped park will produce water savings of between 20-30%.

Urban tree planting The City’s two urban tree planting programs increase the number of trees planted across the City, both in areas found to generate the highest surface temperature and where residents request trees be planted on their verge.

Thermal heat mapping is used to identify areas most prone to the urban heat island effect.

The City’s urban tree planting programs have resulted in increased canopy cover and wildlife habitat as well as reduced urban heat island effect.

The Waterwise Verge Rebate Program led to residents creating biodiverse waterwise verges that save water and provide habitat for wildlife.

Youth engagement

The City also invites young people to have a say in their future by engaging with them through targeted forums such as the City’s Strategic Community Plan Youth Mayoral Workshop and youth representatives on the City’s Strategic Community Reference Group.

The City supports young people to embrace healthy and active lifestyles by providing green urban environments for them to undertake social, recreational and sporting activity. This includes playgrounds, parks, skate parks, sporting grounds, natural areas and more.

The City is proud to receive the AIPH World Green City Awards in Living Green for Water and Youth categories and will continue to lead in addressing the effects of climate change by conserving water through innovation.

The City’s Native Plant Giveaway in 2023/24 provided approximately 8,000 plants to 750 residents, alongside a range of resources and support to create waterwise native gardens for wildlife.

The City provides free native plants through the Native Plant Giveaway and opportunities for the community to attend waterwise garden workshops.

The program provided residents with waterwise plants for their verge and valuable information through workshops and support from City staff to guide their decision making.

Participants also receive information about waterwise irrigation and other water saving strategies to help them save time, water and money. The program provided 2,000 plants to 101 residents, resulting in 65 turfed verges removed and replaced with waterwise native gardens.

The City works closely with schools through the Adopt a Coastline or Bushland initiative. School students across the City ‘Adopt’ a patch of bushland or coastline and learn how to take care of it through rehabilitation and conservation, while learning about wildlife and the importance of the natural environment. Since the program’s initiation in 2006, over 2,500 budding environmentalists from over 30 public schools have participated in the program.

Schools within the City can take part in a free Adopt a Coastline or Bushland program where students learn to protect and conserve their natural environment.

The AIPH World Green City Awards showcase bold and inspiring urban greening initiatives by cities from around the world, all of whom are leading the way in shaping a greener urban future, with the next edition of the awards to be held in 2026.

Kep Katitjin – Gabi Kaadadjan: Building Waterwise Communities for a Climate-Resilient Future To mark the start of National Water Week, Water Minister Simone McGurk unveiled the third Waterwise Action Plan, Kep Katitjin – Gabi Kaadadjan, to further the transformation of Perth (Boorloo) and Peel (Bindjareb) into leading Waterwise communities by 2030.

Part of a broader response to climate change, the plan introduces eight new actions and reinforces 35 ongoing initiatives. These efforts aim to protect Western Australia’s water resources while addressing challenges such as population growth, urbanisation and climate change.

Since its inception in October 2019, the Waterwise Program has enabled Western Australians to save 24 billion litres of water. This includes one billion litres from residential households and 23 billion litres through non-residential water efficiency.

30

The Overflow | Summer 2024/25

Additionally, the program has supported the planting of 10,110 trees and 295,400 waterwise plants, contributing to urban greening and biodiversity.

“The achievements of the Waterwise Program show how collaboration can deliver real change,” Minister McGurk said.

Kep Katitjin – Gabi Kaadadjan builds on the foundations of the earlier plans, integrating water management with urban development to create cooler, greener, and more sustainable cities. Many actions focus on urban cooling through increased biodiversity, improved tree canopy, and enhanced water efficiency.

The new plan also aligns with State Government initiatives, including the Western Australian Climate Policy and the Climate Adaptation Strategy, reflecting a holistic approach to building climate resilience.

Delivered in partnership by 11 State Government agencies, local governments, businesses, and community organisations, the Waterwise Program has earned national recognition.

Earlier this year, it won the Organisational Excellence Award at the Australian Water Awards, underscoring its innovative and collaborative approach.

The plan’s name, Kep Katitjin – Gabi Kaadadjan, reflects its grounding in Whadjuk and Bindjareb Noongar language, meaning "water knowledge."

It emphasises collaboration with Aboriginal communities to integrate traditional knowledge and care for Country into water management strategies.

Kep Katitjin – Gabi Kaadadjan extends its vision beyond Perth and Peel, with plans to explore Waterwise initiatives in regional urban centres.

This acknowledges the unique water challenges faced by communities across Western Australia and the importance of applying lessons from Perth and Peel’s success.

“Our award-winning Waterwise Program has been embraced by Western Australians,” Ms MacLaurin said.

“Climate change impacts all of Western Australia, not just our metropolitan areas,” said Waterwise Program Manager Winsome MacLaurin.

“We are committed to ensuring regional communities can also benefit from Waterwise principles.”

“By improving biodiversity, urban greening, and tree canopy cover, this plan directly addresses the impacts of climate change, helping to cool our cities and improve liveability. It represents a crucial step toward a water-secure future.”

Warm weather prompts waterwise reminder for holiday travellers Holiday makers are being urged to remain waterwise this season, with warm weather and an influx of visitors likely to see increased demand for drinking water in some of WA’s most popular tourist towns.

and take steps to avoid unnecessary consumption. Small changes at a household level make a big difference across the community, helping to ensure drinking water remains secure and sustainable in the face of climate change.”

The populations of holiday hotspots like Dunsborough and Yallingup, as well as Albany, Esperance and Denmark on the south coast and Exmouth in the Mid West, can swell to several times their regular size during the summer break.

The reminder follows a long, hot summer earlier this year and comparatively dry winter across much of the South West Land Division, including Perth’s driest six months on record between October 2023 and March 2024.

Water Corporation Demand Delivery Manager Damien Postma emphasised that excessive or unnecessary water use could put pressure on regional water schemes over the holidays, making it more important than ever to stay waterwise.

“It’s crucial that people, especially visitors to holiday destinations, are mindful of their water use given the seasonal increase in demand over summer,” Mr Postma said.

“We know Western Australians do a fantastic job of being waterwise.

However, we also know summer is getting longer and hotter while winter is getting drier. This means we can’t afford to get complacent when it comes to conserving valuable water supplies.

“Our message is to please be aware of personal and household water use

The Overflow | Summer 2024/25

Across southern WA, average winter rainfall has fallen by 15-20 per cent since the mid-1970s, leading to an 80 per cent reduction in dam streamflow along the Darling Scarp.

Those travelling away from home this holiday season can help conserve drinking water by: • Checking for hidden household leaks and making repairs before going on holidays.

• Making sure garden irrigation is working correctly and set only to designated watering days.

• Switching off water-using appliances before leaving home.

• Keeping showers to under four minutes.

• Avoiding washing cars, boats and pets unnecessarily, or hosing down pavement.

• Ensuring backyard pools are covered to reduce evaporation.

To further help tourist towns prepare for an influx of summer visitors, Water Corporation is working with regional councils and high-water use businesses, such as accommodation providers, to reduce consumption and promote efficiency.

To help save water around the home, special offers are now available to Water Corporation customers in both metropolitan and regional areas.

Those in Perth and Peel can receive a rebate of up to $200 off eligible waterwise irrigation products or services, while various offers tailored to different regions and climates are available to regional customers through Water Corporation’s Waterwise Towns Program.
