DWER AND WATER CORPORATION DELIVER IRRIGATION EFFICIENCY TRAINING TO EMPOWER WA LOCAL GOVERNMENTS The Department of Water and Environmental Regulation (DWER), in partnership with Water Corporation, is proud to support Irrigation Efficiency Training for selected local governments across Western Australia.

Participants included parks and service staff from the Shires of Merredin and Murray, the Cities of Kalamunda and Kwinana, and the Town of Port Hedland. The training, hosted by the City of Kwinana, was developed in response to the extended dry season of 2023–24 and focused on the design, installation, and maintenance of irrigation systems. The program aims to equip local government staff with the practical skills and knowledge needed to manage water more efficiently and sustainably.

Supporting councils to improve irrigation practices aligns with the department’s Kep Katitjin – Gabi Kaadadjan Waterwise Action Plan, which includes a target for 100 per cent of Boorloo (Perth) and Bindjareb (Peel) councils to achieve Waterwise Gold status by 2030.

Pat Ridley, Waterwise Cities Senior Project Officer said, “dry season is a stark reminder of the impacts of climate change and how we need to effectively manage our limited water supplies with less rainfall into the future”.

Improving water efficiency is a cost-effective strategy to build resilience against climate change and plays a vital role in creating waterwise communities. Many local governments across WA are already leading the way in sustainable water use, showcasing how groundwater can be used efficiently to maintain vibrant and functional public open spaces and sports grounds.

Heritage track gets modern upgrade: Kalgoorlie Racecourse’s irrigation overhaul

The upgraded irrigation system incorporates key components such as: • Toro Lynx Smart Hub & Central Control System • On-site weather station • Toro INF55 VIH sprinklers (selected by the client) • Newly installed PE100 MDPE mainlines, ring-mains and submainline pipes.

T

he historic Kalgoorlie Racecourse, located in Western Australia’s Goldfields, has been a centrepiece of regional horse racing since 1896.

Today, the Kalgoorlie-Boulder Racing Club (KBRC) hosts approximately 20 race meetings annually, including the prestigious Race Round event. As a prominent feature of community life, the racecourse attracts visitors and contributes to Australia’s regional sporting calendar.

SUSTAINABLE INFRASTRUCTURE UPGRADE As part of an infrastructure upgrade aimed at improving track sustainability, Racing and Wagering Western Australia engaged Cadsult to provide irrigation design services for the natural turf track.

ENHANCING WATER DISTRIBUTION Incorporating the existing pump station and storage dam, the design minimised the need for additional infrastructure while optimising water distribution.

THE OVERFLOW |

WINTER 2025

To monitor local weather conditions at the Racecourse, a weather station was installed to calculate localised Evapotranspiration (ET) rates and aid in the automated adjustment of irrigation scheduling.

The system irrigates the course proper natural turf area via partcircle sprinklers installed just under, and outside of, the inner and outer PVC railing. No part of the sprinkler is on the actual course proper – why? We don’t want the main attraction at racing meets – the horses, landing on the sprinkler head during the race and potentially causing injury or a fall.

The width of the track is 25.0m; to ensure a high sprinkler application uniformity, as well as the ability to apply 55mm of water across the entire track in a 6-hour period (at night), a sprinkler spacing of 21.0m along the railing was chosen. The nozzle selection was the Toro #55, with a flow rate of 2.35 L/sec at 550 kPa operating pressure.

The resultant minimum sprinkler performance was as follows (based on triangular spacing): • CU: 90% • DU: 85% • SC: 1.2 (5%) • PR: 28mm/Hr To monitor local weather conditions at the Racecourse, a weather station was installed to calculate localised Evapotranspiration (ET) rates and aid in the automated adjustment of irrigation scheduling.

The weather station will monitor the following climatic conditions and will communicate the information back to the Toro Central Control System: • Rainfall • Wind speed, and wind direction • Air temperature • Relative humidity • Solar radiation The weather station will be used in one of two ways; 1. To automatically adjust the irrigation scheduling according to the current climatic conditions, or 2. Use as a tool for current climatic conditions and manually override the irrigation schedule as required.

INSTALLATION Craig Witten, owner of Wittens Irrigation & Design, oversaw the installation of a DID system to combat rapid algae growth in Kalgoorlie’s harsh, dry climate. Without continuous circulation— and given that the site uses recycled water—algae can flourish in holding tanks during hot spells, so the system was configured to inject controlled doses of chlorine directly into the tanks, effectively eliminating bacteria and preventing future blooms.

The entire installation team flew in from Perth and operated on a 10-days-on, 4-days-off roster, alternating with a relief crew of four who commuted back and forth by air and road. Craig and Rachael remained on-site for the duration of the project, ensuring every detail was executed to the highest standard.

BALANCING SUSTAINABILITY AND PERFORMANCE Despite harsh environmental conditions – including limited water supply and variable water quality – the upgraded system is delivering promising results. The turf is establishing well and is expected to provide a high-quality racing surface for upcoming events. .

The system irrigates the course proper natural turf area via part-circle sprinklers installed just under, and outside of, the inner and outer PVC railing.

Cadsult’s top tips for racecourse irrigation design Cadsult Managing Director, Troy Fiscus, and Design Principal, Damian Cullen, suggest the following tips for racecourse irrigation design: Allow sufficient time for your project: Around 23–27 weeks in total Typically, design takes 4–6 weeks, followed by a 3-week tender process and 4–6 weeks for procurement (noting that many irrigation components and parts are sourced from the U.S.).

Installation generally spans 12 weeks, as was the case for Kalgoorlie Racecourse.

Consider infrastructure placement Because horses can be easily spooked, Troy recommends positioning infrastructure thoughtfully. Even static infrastructure within a horse’s sightline can lead to undesirable consequences.

Water at night For efficiency and cost-effectiveness, Cadsult recommends watering at night. If recycled water forms part of the water mix, this can also help track managers comply with regulations requiring a four-hour drying period before track use.

Secure reliable water sources Given the increasing pressure on water resources, securing reliable sources – or incorporating dams and storage tanks for recycled or rainwater – is a fundamental design consideration.

This case study highlights the importance of sustainable water management in the racing industry, particularly in regions where water resources are scarce.

“The aim of the upgrade was to improve the oval’s drainage and reticulation system to create a usable space for residents and sporting clubs.”

City of Gosnells drainage project transforms Jean Garvey Park

J

ean Garvey Park in Gosnells has undergone a significant transformation, thanks to a $750,000 upgrade by the City of Gosnells. Completed in May, the facelift has transformed the 4.5 hectare reserve into a functional sporting ground for the local community.

The redevelopment included the installation of a new drainage system, irrigation and roll-on turf, making the space suitable for sports such as cricket and soccer.

Mayor Terresa Lynes said the park upgrade reflects the City’s ongoing commitment to delivering quality sports facilities.

“The aim of the upgrade was to improve the oval’s drainage and reticulation system to create a usable space for residents and sporting clubs,” she said.

“There is a strong demand for quality playing fields across the City, and this project opens up more public space for games, training and recreational use.”

Middle Canning River evaluation statement released

The Department of Water and Environmental Regulation (DWER) released its Middle Canning River surface water allocation plan: 2024 evaluation statement in June 2025.

The evaluation statement assessed whether the 2012 Middle Canning River surface water allocation plan has been meeting its objectives for managing the use of water from the middle Canning River whilst maintaining sufficient flow regimes to support the river’s environment in a changing climate.

The middle Canning River flows from Canning Dam to Kent Street Weir and provides water for more than 60 licensed users and approximately 30 riparian landholders. Despite its altered nature and urbanised catchment, the middle Canning River retains significant values.

As a key component of the Swan-Canning catchment, the river provides essential ecological functions and holds deep cultural significance for the Whadjuk Noongar people. Additionally, the river plays an important role in the daily lives of residents across the Armadale, Gosnells, Kalamunda and Canning regions,

THE OVERFLOW |

offering recreational and aesthetic value. In addition, maintaining and improving the condition of refuge habitats and the access biota has to them, is vital to supporting ecological health and function in the middle Canning River.

The 2012 Middle Canning River surface water allocation plan established water allocation limits and ‘river release’ rules, which govern the controlled release of treated scheme water from Canning Dam at six designated points. These measures help sustain the health of the river below the dam, benefiting both the environment and local communities.

The evaluation was underpinned by an extensive review of monitoring data, including streamflow and ecological data, collected through triennial river health assessments at four important refuge pools. These assessments showed that the river is displaying signs of ecological stress, particularly at the sites lower down in the catchment where habitat and water quality are less favourable.

The evaluation of the 2012 plan highlighted that, for the most part, management under the plan has been effective over the past decade. It also found that as climate change drives the seasons to become warmer and drier, achieving minimum streamflow thresholds will become increasingly challenging into the future.

“Along with the rest of south west Western Australia, the Canning River is facing challenges associated with hotter and drier conditions due to climate change,” Principal Water Planner Michael Hammond said.

WINTER 2025

River health assessments of important refuge pools informed the evaluation of the 2012 plan.

Rainfall and inflows to the Canning Dam between the periods 1975–2008 (the period on which the assessment of river releases in the 2012 plan was based) and 2009–2023 (the period since the assessment) have dropped by 11 per cent and 66 per cent respectively.

Inflows to Canning Dam have dropped by

“As the climate continues to change, our approach to water management must adapt to help ensure the ongoing health of our rivers,” Mr Hammond added.

The evaluation highlighted that with ongoing declines in streamflow, challenges in maintaining minimum river flows and concerns from stakeholders regarding river health, the river release rules will be reviewed to ensure the middle Canning River remains resilient to climate change pressures.

66% from 1975–2008 to 2009–2023.

From 1975 to 2008 and 2009 to 2023 there was an increase in average monthly temperatures, particularly throughout the summer months. To meet minimum flow thresholds during these warmer months, larger volumes of water are required to be delivered from release points below Canning Dam. Climate projections for this area indicate rainfall will continue to decline into the future.

In response, DWER is taking proactive steps to mitigate climaterelated impacts, including recouping unused water entitlements, reducing allocation limits and adjusting river release arrangements to better protect the river’s ecological health.

These changes are helping ensure that more water is available to support the river’s ecological, cultural and community values during particularly dry years and align with the broader objective of balancing water use with environmental and community needs in a rapidly changing climate.

The Trusted Connection Behind The Royal Sydney Golf Course Upgrade

RESULTS AND IMPACT To meet the project requirements, a PN16-rated Plasson system was installed using a combination of mechanical, compression and electrofusion fittings. The site’s need for rapid irrigation called for high water flow rates, which required the use of 90mm laterals instead of the typical 63mm. The Plasson system offers these benefits: >

Long-Term Peace of Mind. A welded PE100 system exceeding the requirements of the Australian standard provided a 100-year design life and gave the team confidence in long-term reliability, eliminating the risk of underground leaks and future repairs.

>

Cost Savings. The Plasson Plassaddle significantly reduced installation time, allowing crews to work faster and more efficiently. Its durable, fast, and easy-to-install design also reduced labour costs and future maintenance.

>

Corrosion-Free Performance. With no metal parts or bolts, the system eliminated corrosion, seizing, and the need for antiseize treatments, delivering a truly low-maintenance solution.

>

Certified Quality. Plasson’s PN16 products, backed by thirdparty certification to Australian Standards, gave the project team full confidence in the materials, knowing performance wasn’t just claimed, but certified.

>

Faster installs without compromise. Mechanical fittings on the laterals helped the crew significantly reduce installation time, by up to 6 weeks, allowing the project to stay on schedule while still meeting quality standards.

>

Water usage reduced by 20%. By allowing Royal Sydney to deliver more precise and economical course irrigation, combined with the new native landscape, water usage will be reduced by 20%, and up to 73 million litres of water will be saved per year.

How Plasson Helped Transform One of Australia’s Premier Golf Courses.

When it comes to redeveloping a world-class golf course, nothing can be left to chance. The enormous transformation of Royal Sydney Golf Club, a prestigious 18-hole course nestled in Sydney’s eastern suburbs, called for the best in design and infrastructure.

Tasked with modernising the course while keeping parts operational, the project team faced complex challenges: tight timelines, coastal soil conditions, restricted access, and the pressure to quickly return the course to members. For Royal Sydney Golf Club Superintendent, Adam Marchant, and irrigation contractor Gosford Irrigation, it meant finding a solution that could be installed quickly, perform under pressure, and stand the test of time.

That’s where Plasson Australia proved to be the ideal solution.

THE OVERFLOW |

WINTER 2025

CHALLENGES An iconic course in Australia, completing the upgrade within a tight timeline presented several challenges: > Tight Delivery Schedule. Swift installation was required within a narrow construction window, leaving little room for delays. > Limited Site Access. Restricted working space made equipment coordination difficult while keeping parts of the club open to members. > Coastal Soil Conditions. Saline, sandy soil caused issues like galling and corrosion with traditional metal fittings. > Labour Disruption. The desire to limit issues with anti-seize compounds and lost hardware in trenches, potentially slowing down installers and creating unnecessary reworks. > Infrastructure Demands. Upsizing from 63mm to 90mm pipe was necessary to support larger watering zones, reduce turf closure times, and future-proof the system for expansion. > Pressure to Perform: With member expectations high and full-course redevelopment underway, only reliable, efficient components could meet the required operational and performance standards.

SOLUTIONS Electrofusion welded mainlines Sizes 90mm through to 450mm PE100 pipe were installed in open trenches. Plasson’s SmartFuse electrofusion fittings, welding machines and installation tools and on site training helped the installers achieve high quality welds.

“This wasn’t just any irrigation upgrade—it was part of a complete redevelopment of one of Australia’s most iconic golf courses. Every element had to meet the highest standards, both in terms of performance and reliability. We were working within a very narrow construction window, with limited access and demanding conditions, including coastal soil and high salinity. We needed products we could trust that would hold up under pressure and stand the test of time.

That’s why we chose Plasson. Their mechanical saddles and electrofusion fittings gave us the flexibility to work efficiently without compromising quality. The bolt-free Plassaddle connections saved Gosford Irrigation weeks on the ground, and the PN16-rated system gave us confidence that what we were putting in the ground was going to last. Just as important, their team backed us every step of the way with advice, training, and on-the-ground support that helped us stay on track.

We only work with products we believe in, and with Plasson, we had total confidence we were getting a solution that matched the calibre of this course.” Adam Marchant, Royal Sydney Golf Club Superintendent

Plassaddle Sprinkler Connections Bolt-free mechanical saddles were quickly installed, connecting laterals to the sprinkler swing arms. With over 1,800 units fitted, the innovative system saved up to 6 weeks on the schedule.

Service PE Lateral Isolation Ball Valves Plasson Full-bore, quarter-turn PE ball valves reduced head loss and pumping costs for the project.

The valves actuated from a simple riser allowed smaller pits and lids reducing solid surfaces on the course.

W

estern Australia’s diverse climates – from Perth’s traditional four seasons to the distinct wet and dry cycles of the Kimberley and Pilbara, and the subtle shifts in central desert areas like the Goldfields – significantly impact mental health. Seasonal transitions can be especially challenging for rural communities and agricultural sectors reliant on irrigation.

SEASONAL IMPACTS ON MENTAL HEALTH IN WA Seasonal Affective Disorder (SAD), typically linked to reduced daylight and disrupted routines, can heighten feelings of anxiety, fatigue, and low mood during autumn (Melrose, 2015). Across WA: Perth and South West: Shorter days and cooler weather reduce outdoor activities, potentially impacting mood, and social interactions.

Kimberley and Pilbara: Rapid changes from wet to dry seasons increase workload pressures, potentially exacerbating fatigue, and stress.

Central Desert Regions (Goldfields): Less predictable seasonal shifts can create uncertainty and increased stress due to inconsistent workloads.

CHALLENGES IN RURAL AND IRRIGATION REGIONS In WA’s rural areas, isolation and demanding physical tasks compound mental health risks, particularly during seasonal changes. Key irrigated regions such as the Ord River, Gascoyne, Harvey Water, and Pilbara face unique pressures due to seasonal workload fluctuations and water availability concerns.

Organisations like TIACS (This Is A Conversation Starter) provide valuable, free mental health support tailored specifically for WA’s trade and rural communities, addressing the needs of isolated and remote workers.

EMPLOYER RESPONSIBILITIES UNDER WA’S WHS REGULATIONS The WA Workplace Health and Safety (WHS) Act (2020) requires employers to manage psychological risks, including excessive workloads, isolation, and seasonal environmental stresses.

Recommended strategies include: • Providing region-specific mental health awareness and training.

• Offering flexible work arrangements to balance workloads during busy seasons.

• Fostering open communication and supportive workplace environments.

• Ensuring easy access to Employee Assistance Programs (EAPs) and local mental health resources.

Organisations like TIACS provide free mental health support tailored specifically for WA’s trade and rural communities.

Practical Strategies to Support Mental Health 1. Optimise Natural Light: Prioritise daylight exposure to manage mood and energy levels.

2. Community Connection: Engage with local groups, industry networks, or sporting clubs to reduce social isolation.

3. Access Regional Support Services: Utilise WA-based mental health resources, such as TIACS and the Regional Men’s Health Initiative.

4. Monitor Fatigue and Workload: Recognise early signs of burnout, adjusting workloads proactively.

5. Normalise Conversations: Encourage open dialogue about mental health, reducing stigma and creating supportive workplaces.

EFFECTIVELY MANAGING CHANGE Like leaf litter enriching soil health, proactive mental health management enhances resilience across WA’s agricultural and rural communities. Adapting mental health strategies to specific regional challenges ensures better preparedness for seasonal transitions.

Water Corporation lends a helping hand to Kimberley community projects

W

ater Corporation’s long-running Kimberley Community Grants Scheme has awarded over $746,000 to 132 not-for-profit organisations since 2016 for projects that uplift, empower and connect communities across the Kimberley.

Funds come from the sale of Rhodes grass hay for fodder, grown using recycled water from the Broome North Water Resource Recovery Facility (wastewater treatment plant) - an environmentally sustainable way to reuse large volumes of treated wastewater.

The scheme is run in partnership with the Lions Club of Broome and provides grants of up to $10,000 to not-forprofit organisations and schools for projects that support and empower local communities in the Kimberley.

This year, the scheme provided nearly $80,000 to 14 projects, including Wangki Radio, based in the Fitzroy Valley. Wangki Radio plan to use their $10,000 grant to complete a broadcast studio upgrade, to better deliver its communication services in a digital age.

Tomato Trial

Efficacy and effectiveness of Structured Water Vortex Generators on yield, quality, and water use efficiency in organic tomato production

ABSTRACT A 19-week grow trial (30 September 2024 to 10 February 2025) at South Regional TAFE, Bunbury Campus, Western Australia, evaluated the efficacy of the Structured Water Vortex Generator (PW50, President Water) on organic Solanum lycopersicum (San Marzano) tomato production. Three garden beds were compared: Bed 1 (control, municipal water), Bed 2 (PW50 Vortex Generator), and Bed 3 (PW50 Vortex Generator + GARD/RV carbon/KDF filter).

WATERWISE IRRIGATION PROGRAMS FOLLOW US ON SOCIAL MEDIA We post endorsed member spotlights, tips and tricks and any upcoming events weekly on Facebook and LinkedIn. We encourage you to like, follow and share our posts throughout your network!

The alternative hypothesis (H₁) posited that the Vortex Generator would significantly increase yield and quality. Results confirmed H₁, with Bed 2 yielding 30.91% more than the control and Bed 3 achieving a 225.76% increase over the control, with a 25% reduction in water use across treated beds (Bed 2+3). Bed 3 produced larger, darker red tomatoes, although a small amount of Blossom End Rot (BER) occurred, likely due to a calcium deficiency resulting from rapid growth. These findings suggest that Vortex Generators enhance yield, quality, and water usage efficiency (WUE), with implications for sustainable horticulture.

INTRODUCTION Water structuring through vortex motion, a natural process, enhances the physical, chemical, and biological properties of water, potentially benefiting plant growth. Structured Water Vortex Generators mimic this process, reportedly increasing oxygen levels, nutrient bioavailability, and microbial activity, leading to higher yields, improved Brix values, and reduced water and fertiliser needs. In regions like Western Australia, where water quality can challenge horticulture, such technologies offer a sustainable solution.

Bed 1

Bed 2

This study tested the PW50 Vortex Generator (President Water, Western Australia) on organic San Marzano tomato production, hypothesizing that it would improve total yield, fruit quality, and WUE compared to a control. A secondary treatment combined the PW50 with a carbon/KDF filter to assess synergistic effects and total elimination of chlorine.

EXPERIMENTAL DESIGN The trial was conducted from 30 September 2024 to 10 February 2025 at SR TAFE, Bunbury Campus (33.35°S, 115.64°E). Three identical raised garden beds (2750 mm × 750 mm, steel) were prepared with soil from prior mustard cover crops, topped with 20 mm organic compost and 75 mm hardwood mulch. Each bed was planted with four San Marzano tomato seedlings, six marigolds, six cosmos, and two cornflowers (companion plants selected for pest management and beneficial insect attraction). Beds were trellised with reo-concrete mesh and irrigated via 19 mm poly-pipe with three emitters connected to mains water. Irrigation was set at 20 minutes daily, with watering volumes confirmed by bucket test.

Each bed was planted with four San Marzano tomato seedlings, six marigolds, six cosmos, and two cornflowers.

Bed 3

Bed 3 produced a 225.76% increase over the control. Water use was reduced by 25% in Beds 2 and 3 via flow restriction. Tomato size and color varied, with Bed 3 fruits being larger and darker red (Table 2, Fig. 1). Plants in Beds 2 and 3 exhibited darker green foliage and greater turgidity than the control.

BER occurred in Bed 3, presenting as brown spots on fruit bases (Fig. 5), likely due to calcium depletion from rapid growth. The application of powdered milk mitigated this issue. Yield and quality data strongly supported H₁, with the combined treatment (Bed 3) outperforming others.

IN THE GARDEN WITH

• Bed 1 (Control): Mains water, unrestricted flow.

• Bed 2 (Vortex Generator): Mains water + PW50 Vortex Generator, flow restricted to 75% capacity via 19 mm ball valve.

• Bed 3 (Combined): Mains water + PW50 Vortex Generator + GARD/RV carbon/KDF filter, flow restricted to 75% via 19mm ball valve. w Seedlings in each bed were treated with Neutrog GoGo Juice (40ml in 10litres of water) at planting and twice during the trial. No synthetic soil amendments were used. On one occasion, Coles Brand Milk Powder (1kg in 10 litres of water) was foliar applied in an endeavour to address Blossom End Rot to Bed 3 only.

DATA COLLECTION Tomatoes were harvested periodically, weighed using kitchen scales, and measured with a tape measure. Visual observations of plant health and fruit quality were recorded weeklyand photographed. Data were analyzed descriptively, with percentage changes calculated relative to the control.

RESULTS Total yields (Table 1) showed significant differences across treatments. Bed 2 yielded 30.91% more than Bed 1 (control), while

THE OVERFLOW |

WINTER 2025

DISCUSSION The PW50 Vortex Generator significantly enhanced tomato yield and quality, aligning with prior research on structured water’s benefits. The 225.76% yield increase in Bed 3 suggests a synergistic effect of vortexing and carbon filtration, likely improving water quality and nutrient delivery. The 25% water reduction in treated beds highlights improved WUE, a critical factor in sustainable horticulture.

Larger, darker red tomatoes in Bed 3 indicate enhanced nutrient uptake, though BER’s occurrence suggests rapid growth outpaced calcium availability. This was managed effectively, but future trials should include soil nutrient testing to optimise conditions. The darker foliage and turgidity in treated beds further indicate improved plant vigor, consistent with claims of increased microbial activity and oxygen levels.

Limitations include the lack of pre-trial soil analysis and holiday observation gaps (December 2024–January 2025). Future studies should quantify brix values, soil moisture, and nutrient uptake rates to elucidate mechanisms behind these outcomes.

CONCLUSION The PW50 Vortex Generator, particularly when paired with a carbon/KDF filter to neutralise, markedly improved organic tomato yield (up to 225.76%), quality, and WUE (25% reduction) in this trial. These findings support its potential to transform horticulture by reducing resource inputs while boosting productivity. In further research/trials are recommended to validate nutritional benefits (e.g., brix values), optimise and test soil focusing on calcium management, and assess scalability across diverse crops and soils.
