Chairpersons Report

I

recently heard a live band cover the iconic song ‘Rain’ by Dragon. It was a fitting tribute and a surreal experience standing amongst a crowd singing in unison, ‘it’s been raining for so long, don’t you go out in the rain, don’t go out in the pouring rain’. We have just had record-breaking rainfall for the past few months, and I think how different it was back in spring 2024, when we had to turn the reticulation on as of 1 September. The unseasonal growth results in season creepout and affects scheduled maintenance. Reticulation scheduling and maintenance are likely the last things on the mind when weather conditions have been so wet. I had a squiz through the BOM website and found some interesting stats, even 125 years of plotted rainfall. (https://www.bom.gov.au/climate/history/ rainfall/). These conditions this Djilba season mean a season stretch of late spring and possibly a long, hot summer. With all this rain, there is a real concern about fire mitigation, and DFES is issuing an early warning to the public to start early to prepare for this fire season.

Thank you to all of those who came to the Waterwise Irrigation Expo, group leaders who volunteered, trade show participants and delegates. It was a fantastic day with lots of great displays, learnings from The Vines Golf Course irrigation upgrade and pump house case study and who could forget the competitiveness on the mini golf competition. I managed to see 4 hole-in-ones in a row. It was amazing to see the thirst in the industry for technology and learning. I think we should rename it to ‘sucesspo’ as it was such an epic event.

Congratulations to the Waterwise winners for some great examples of businesses and technology out there who are kicking some key goals and are great leaders in the industry, showcasing best practice.

I’d like to acknowledge the tireless work of Bec New and the committees in order to make the day a great success. A mountain of work was conducted to make it all happen, and it really paid off on the day.

The agreement between Irrigation Australia and Water Corporation has been signed and endorsed, which outlines the KPIs and targets for both parties to achieve working together over the next 12 months.

FROM TRAINEESHIP TO APPRENTICESHIP: BUILDING SKILLS FOR THE FUTURE Irrigation technicians are the backbone of sustainable farming, thriving urban green spaces, and water-efficient landscapes across WA. Yet with only 283 technicians statewide—and demand continuing to grow across agriculture and urban development—we face a critical workforce shortage.

To address this, the Food, Fibre and Timber Industries Training Council, together with industry, has submitted a proposal to transition the Certificate III in Irrigation Technology from a traineeship to a recognised trade apprenticeship. This change would strengthen the profession’s standing, provide deeper practical skills training, improve career pathways, and support workforce development in regional areas. The submission is currently with the State Training Board, and the approval process is expected to take several months. We will continue to keep you updated as developments occur, and we thank everyone who has contributed to this important project so far.

Brookton Project: Harnessing Solar Power to Deliver Smart, Sustainable Water Solutions

to support irrigation and livestock. The goal? A system that would run itself, deliver consistent flow, and reduce reliance on external power.

BD Water kicked off the project with a desktop hydrogeological assessment, reviewing nearby bore data, aquifer maps, and regional geology. The site itself was low-yielding, typical of the Brookton region.

BACKGROUND In Brookton’s dry landscape, where the sun is abundant, but water is scarce, one local farm faced a challenge that many in WA’s agricultural regions know all too well: an insufficient water supply.

This was followed by an on-site inspection, where our team evaluated soil types, elevation gradients, and access points.

We identified 3 potential bore locations, each with distinct characteristics.

This wasn’t just a case of needing “more water.” The issue was deeper: a low-producing site, unpredictable bore yields, and a farm that needed water not just now but reliably and efficiently for years to come.

The final location was selected in consultation with the client, balancing:

BD Water was called in to design, manage, and deliver a holistic water system that tackled the bore yield issue and futureproofed the operation using solar technology. When water is precious, every drop matters.

PLANNING WITH PRECISION: FROM DESKTOP TO DRILL SITE Every successful water solution starts with a solid plan — and BD Water’s Brookton project was no exception. The client, a private farm operator, needed a reliable, off-grid water source

Distance to existing infrastructure Optimal soil and rock types Elevation and topography Property lithology and aquifer potential

The chosen site sat above a fractured rock zone — a geological sweet spot in the Brookton region. These zones often contain productive aquifers above the bedrock shelf, with water-bearing fractures in intrusive rock types like basalt, dolerite, and gabbro.

Our team noted that the base bedrock typically sits around 50–60 metres, making it ideal for a bore targeting deeper, more reliable water sources.

SPRING 2025

Key takeaways > BD Water delivered a fully off-grid solarpowered groundwater system for a farm. > Bore drilled to 80m in fractured rock.

A 0.8kW solar pump system, pumping water along 300m to an existing 20,000L tank. > Automated pressure-based start/stop system. > Integrating hydrogeology, bore drilling, solar and rural irrigation infrastructure. > Long-term benefits include sustainability, reliability, and reduced operational costs.

SOLAR-POWERED SIMPLICITY: PUMPING WITH PRECISION Two weeks after drilling, our team returned to install the solar pump system — a compact yet powerful setup tailored to the site’s needs. The system was designed based on actual bore performance, ensuring optimal pressure and flow.

SYSTEM COMPONENTS A fully solar-powered pumping system designed to deliver a consistent, steady flow throughout daylight hours: Pump: • 0.8kW Nastec NERA 01/02H • Operating specs: 10L/min at 900kPa to 73m

DRILLING THE BORE: FAST, FOCUSED, AND FIT FOR PURPOSE With the location locked in, BD Water mobilised its drilling team.

The bore was drilled to 80 metres in a single day, showcasing our efficiency and experience in rural WA conditions.

The bore was drilled through hard granite – no easy feat – but with our custom-designed rigs and experienced crew, the job was completed efficiently and safely. Dual screens were installed at the best-yielding depths, allowing us to optimise the flow from this low-producing aquifer.

Solar Array: • 2x 415W Trina panels • Pole-mounted frame for optimal sun exposure Infrastructure: • New headworks, rising main, cabling, and control valves • Automated pressure-based start/stop system • Commissioning and performance testing

Here’s the bore construction breakdown: • • • • •

The fractured rock zone proved productive, confirming our pre-drill assessments. With flow rates and bore construction data in hand, we moved into the next phase: designing the solar pumping system.

The result was approximately 10 to 15 litres per minute, with a salinity of 800ppm – a strong result for the region and well within the usable range for agricultural purposes.

The pump delivers water along a 300 metre pipeline to an existing 20,000L tank, with a gentle elevation gradient across the property. The system is designed for low maintenance and high reliability — ideal for remote farming operations.

This system pumps water gradually into an existing 20,000L tank, making the most of every minute of sunlight. It’s simple, sustainable, and built to last.

DELIVERING SOLID, RELIABLE RESULTS The client is getting a consistent 10 LPM with smooth performance with the system now live. It’s not a high-yield bore, but thanks to our integrated approach, the water is captured steadily throughout the day and stored efficiently for ondemand use.

There is no need to worry about power outages, costly diesel pumps, or constant system monitoring. It’s the kind of quiet, reliable solution that just works – day in and day out.

And for regional farms like Brookton, that peace of mind is worth its weight in gold.

AUTOMATION THAT WORKS WHILE YOU DON’T One of the client’s key goals was automation — and BD Water delivered. The pressure-based control system ensures the pump starts and stops automatically based on tank levels and demand.

No manual switching, no guesswork. Just reliable, consistent water delivery.

This “set and forget” approach means the farmer can focus on managing crops and livestock while the system quietly does its job in the background. It’s a perfect example of how smart water infrastructure can simplify rural operations.

INSTALLATION TIMELINE: QUICK TURNAROUND, MINIMAL DISRUPTION BD Water prides itself on delivering fast, efficient installations — and Brookton was no exception.

Day 1: On-Site Assessment and Preparation Day 14: Bore drilled to 80m, casing and screens installed Day 28: Solar pump system installed over 2 days Day 30: System commissioned and operational This rapid turnaround minimised disruption to farm operations and ensured the client had access to water as quickly as possible.

Benefits That Flow: Short-Term Wins and Long-Term Value Short-Term Benefits > Immediate access to groundwater for irrigation and livestock > Off-grid water delivery with $0 electricity costs > Minimal disruption during installation Long-Term Benefits > Sustainable water supply with reduced carbon footprint > Low-maintenance infrastructure designed for longevity > Increased farm resilience during dry seasons > Scalable system — additional tanks or irrigation lines can be added later > Reduced operational costs and improved water security

CHALLENGES AND CLEVER SOLUTIONS No project is without its quirks — and Brookton had a few.

We navigated the site’s geology with care. The presence of intrusive and volcanic rock types — basalt, dolerite, gabbro — was a positive indicator for water-bearing fractures. Our team’s understanding of local lithology helped guide both the bore location and construction method.

The fractured rock zone required careful drilling to avoid collapse, which we mitigated with pre-collaring and casing. The site’s elevation and distance to the tank also required precise pump sizing to ensure adequate pressure and flow.

By waiting until the bore was drilled to finalise the solar system design, we ensured the pump matched the actual bore yield and depth — not just theoretical specs. That’s BD Water’s way: design informed by data, not guesswork.

WHY BD WATER?

Smart Scheduling Helps Bayswater Save Water OPTIMISING SPORTS TURF IRRIGATION IS EASIER THAN YOU THINK!

WHY COUNCILS NEED TO ACT NOW

These data provided some important insights (Figure 1A):

Councils play a key role in maintaining green spaces in cities.

Irrigation is essential for keeping these areas healthy. But Perth’s water supply has been under pressure for years. Declining rainfall, urban growth, and heavy use of groundwater have all added stress. The Gnangara aquifer has been hit the hardest.

• Irrigation usually started at the right time in September • Watering ramped up correctly through spring and early summer • But irrigation stayed too high late in summer and into autumn

As part of efforts to protect groundwater, councils north of the Swan River will see a 10% cut to water allocations by 20281. This means they must keep parks and sports fields attractive and fitfor-purpose while using less water.

This article looks at how the City of Bayswater is tackling this challenge. They used SWAN Systems software with their Aquamonix Rainman controllers to optimise irrigation schedules and save significant amounts of water.

WATER ALLOCATIONS: A TIGHTENING BUDGET Water licences for public green spaces in Perth usually allow 7,500 kL/ha. These areas include sports fields, parks, gardens, and street verges. Councils have some flexibility with how water is used within a licenced area. For example: • A premium oval might need 10,000 kL/ha • A shaded park could do well with less than 5,000 kL/ha

THE SHOULDER SEASON PROBLEM The data show that autumn offers the biggest chance to save water. But this can be tricky. The weather changes a lot, and turf managers are busy. Even if they check soil data, adjusting irrigation schedules may not be straightforward. They must decide how much to cut back or increase watering, all the while watching for rapidly changing weather conditions. Because of this, managers may keep irrigation high in autumn as a “safety net” against sudden heat. This is where SWAN Sync comes in.

SMART SCHEDULING WITH SWAN SYNC SWAN Sync lets SWAN send optimised irrigation schedules straight to controllers. SWAN predicts how much water the turf will need each day over the next week using weather, irrigation and soil moisture data, along with rainfall and evapotranspiration forecasts.

This approach makes it possible to water each type of space properly without going over the allocation.

The process is simple:

But the coming cut to an average allocation of 6,750 kL/ha in 2028 will make things tough. Councils will need better infrastructure, smarter water management, or both.

1. In SWAN, click “optimise” 2. Review, approve and save the schedule 3. The system sends it to the controllers automatically

FINDING POTENTIAL WATER SAVINGS

This takes about 15 minutes, once or twice a week. It means irrigation aligns with current conditions, saving water without extra effort.

The first step to knowing if water savings are possible is knowing when and where water is used.

The City of Bayswater irrigates many sports fields using Aquamonix Rainman controllers. Since 2018, they’ve used SWAN Systems to collect controller data on 15 ovals. SWAN automatically collects and analyses irrigation and weather data, tracks changes in soil moisture and compares irrigation applied to actual turf water demand over time.

14

So, February to April became the clear target for savings. Soil moisture readings confirmed this: The sports fields stayed wet longer than needed.

THE OVERFLOW |

DOES IT SAVE WATER? Yes. Starting with the 2022-23 season, Bayswater added SWAN’s schedule optimisation with SWAN Sync to two ovals – Emberson and RA Cook. Comparing the years before and after implementing SWAN Sync:

SPRING 2025

• In 2019, 2020, 2021 and 2022, water use was between 3040% above turf demand from February - April • In 2023, 2024 and 2025 the excess for the same period dropped to under 10% (an acceptable buffer against underirrigating) A comparison of irrigation patterns before and after implementation of SWAN Sync at Emberson Reserve is shown in Figure 1. This shows irrigation matched turf needs much better after using SWAN Sync (Figure 1A).

HOW MUCH WATER CAN BE SAVED? Every season is different. For example, 2023-24 was one of Perth’s hottest and driest years, with almost no rain from September to May2. Turf needed about 15% more water in 202324 than average. This illustrates the challenge of comparing between years to determine whether savings have been made.

However, if a consistent excess of irrigation applied relative to actual crop demand is mitigated by a change in practice, then it’s clear that water savings have been achieved. SWAN Sync has improved annual water application efficiency at the two ovals: • Emberson Reserve: at least 20% more efficient • RA Cook Reserve: about 15% more efficient This equates to an average of 1,500 kL/ha saved for these high-use ovals. Published scientific research shows smarter scheduling can often cut water use by 20% or more. Importantly, there was no loss of turf quality due to the water saving.

This was monitored by satellite imagery (NDVI) that showed greenness was maintained through the periods of optimised scheduling and SWAN Sync.

Figure 1. Monthly turf water demand (green bars) vs. irrigation applied (dark blue bars) at Emberson Reserve. A. Sep 2021 – May 2022 (before SWAN Sync): Irrigation was scheduled using accepted standard practice, with monthly budgets based on historical average evapotranspiration3. The highlighted months (Feb–Apr 2022, orange box) show periods of excess irrigation compared to actual turf demand. The arrows indicate potential water savings.

B. Sep 2022 – May 2023 (after implementing optimised irrigation scheduling

with SWAN Sync): The highlighted months (Feb–Apr 2023, orange box) show a marked reduction in excess irrigation, with application much closer to turf water demand.

Because of this success, Bayswater will roll out SWAN Sync at three more ovals in 2025.

Testimonial

THE DATA IS ALREADY AVAILABLE - LET’S USE IT TO SAVE WATER!

The introduction of SWAN Systems into the City’s irrigation monitoring tools has significantly enhanced our approach to predictive scheduling.

Councils do their best with limited time and, often, aging infrastructure. Continuous data analysis is the only way to provide actionable decision support that drives immediate improvements in water efficiency. Fortunately, most councils already collect this data. They just need to use it! By combining SWAN’s data analysis with SWAN Sync-enabled controllers, irrigation managers get an easy, push-button solution to improve irrigation efficiency and cut water use.

The SWAN Sync Trial has highlighted the potential for more efficient water use, and we intend to expand this trial by incorporating three additional grounds with differing characteristics to the current sites. We look forward to analysing the results of this expansion.

The moisture sensor data collected from the current sites often aligns closely with the calculations from SWAN Systems, creating a synergistic relationship that boosts our confidence in our irrigation strategies.

Our field staff, already well-versed in the specific needs of the various grounds, are responsible for programming the irrigation systems. The insights provided by SWAN Systems serve as a valuable reference tool, further assisting them to make informed decisions on irrigation management. Together, these tools will enhance our ability to optimise water usage while maintaining healthy landscapes.

As the State Government leads a transition away from coal, effective water planning is more critical than ever to support Collie’s future.

ITS100B

The area covered by the allocation plan features a unique and contrasting landscape. It includes areas of natural beauty, such as the Collie River Valley, and an emerging tourism sector – all set against a backdrop of farming, coal mining, and power generation.

In July 2025, the department published the second plan evaluation showing how the allocation plan has performed against its water resource objectives between 2018 and 2024.

The evaluation shows continued progress towards some of the plan’s objectives. However, abstraction above allocation limits to support coal mining under State Agreements and the ongoing warming and drying climate have also raised challenges for managing water in the region.

This evaluation highlights the importance of adapting to ongoing climate change and managing overallocation to progress the allocation plan’s objectives. The Collie area is currently undergoing a significant industrial transition through the Collie Just Transition plan. This will provide new priorities for water management in the Upper Collie and further opportunities to adapt to changing rainfall, streamflow, and groundwater recharge as the climate changes.

The department is proactively conducting technical studies and collaborating with multiple agencies, including the Department of Energy and Economic Diversification, the Department of the Premier and Cabinet, and the Department of Primary Industries and Regional Development to support future economic and environmental outcomes in the Collie Coal Basin. The department will also consider updating the current water allocation plan in line with State Government priorities and findings from monitoring and scientific investigations, such as the State Groundwater Investigation Program - Collie project.

Collie’s transformation presents both challenges and opportunities for water resource management. As the region shifts toward new industries and adapts to a changing climate, the State Government is laying the groundwork for a resilient future, where water continues to support Collie’s evolving landscape, economy, and community values.

Iron and manganese fouling in Australian groundwater bores UNDERSTANDING THE PROBLEM Iron and manganese are present in many Australian aquifers, especially in regions with low-oxygen conditions underground.

When pumped to the surface, these dissolved metals oxidise and precipitate out, forming crusts, slimes, and nodules that interfere with bore efficiency.

ARTICLE BY DAVID BENNETT

Snapshot > Groundwater bores across Australia often face performance issues caused by the accumulation of iron and manganese deposits. > Iron deposits are widespread across Australia, while manganese is prevalent in the east. > When pumped to the surface, these dissolved metals oxidise and precipitate out, forming crusts, slimes, and nodules that interfere with bore efficiency and pump operation. > Iron forms reddish slime and crusts that are moderately difficult to remove, while manganese creates stubborn black biofilms that require specialised cleaners and careful treatment to prevent rapid regrowth. > Best practices for bore treatment and performance include regular monitoring, mechanical and chemical cleaning, disinfection and flushing.

Over time, this buildup can drastically reduce flow rates, increase maintenance costs, and even lead to premature pump failure. Manganese is particularly troublesome due to its tenacity and complex chemistry, especially in areas like Eastern Australia, where it’s known to be prevalent.

roundwater bores across Australia often face performance issues caused by the accumulation of iron and manganese deposits. These naturally occurring minerals can foul pumps, clog screens, and reduce water yield – particularly in agricultural and industrial wells. Understanding the differences between iron and manganese fouling is key to managing and treating these problems effectively.

keep the new pipes clean.

Iron and manganese fouling is a persistent issue for many well owners and operators across Australia. Understanding the difference between the two and tailoring your treatment methods accordingly, can help restore and maintain well performance for the long term. Proactive maintenance and the right combination of tools and chemicals are your best defence against recurring problems.

BEST PRACTICES FOR TREATMENT AND PREVENTION 1. Regular monitoring Keep logs of bore yield, drawdown, and water quality to catch early signs of fouling.

2. Mechanical cleaning Wire brushing, surge blocks, or airlift pumping can remove much of the biofilm and mineral buildup before chemical treatment.

3. Chemical cleaning Use targeted cleaning agents such as BoreSaver Ultra C for iron, or MultiKleen/EZECO for manganese issues.

Wet winter belies true impact of declining streamflow to Perth dams

W

“Prior to 2000, we needed around 100mm of rain to generate 10 billion litres of streamflow. Now we need closer to 500mm for the same yield.

“Historically, we had much more consistent rainfall throughout the year, especially in the shoulder seasons of autumn and spring. Increasingly, however, the only material rain comes in winter.

Since the mid1970s, a

ith recent rainfall across Perth and southern WA, it’s easy to assume our dams are full to brim. But the connection between rainfall and dam levels isn’t so simple.

15–20%

rainfall reduction has led to an

In fact, just 35 billion litres of runoff – or streamflow – has flown into dams along the Darling Scarp this year, despite it being Perth’s wettest winter in 30 years.

80% decrease in streamflow.

That’s a far cry from the pre-1970s average of 420 billion litres of streamflow, and around half the 76 billion litres averaged annually since 2010.

Water Corporation General Manager of Assets Planning, Evan Hambleton, said the decline was due to repeated years of below average rainfall in autumn and spring leaving dam catchments increasingly thirsty.

“Dam catchments are like massive sponges, and it’s only once the ground is saturated down to the groundwater or bedrock we start to see meaningful streamflow,” Mr Hambleton said.

22

THE OVERFLOW |

SPRING 2025

“Because our catchments are drier for longer, streamflow begins later and ends earlier - reducing the amount of drinking water we receive from natural runoff.”

“It’s crucial we don’t view desalination as a licence to waste water. While it’s a vital part of our water supply strategy, it will never replace the need to be waterwise.”

Since the mid-1970s, a 15–20 per cent rainfall reduction has led to an 80 per cent decrease in streamflow. Today, rainfall makes up just 10-15 per cent of drinking water supplies, while most water in our dams actually comes from groundwater and desalinated seawater.

Climate-independent desalination is a particularly important part of our supply mix, but it will never replace the need to be waterwise, according to Mr Hambleton.

“Desalination is such a vital source because it doesn’t rely on rainfall, however, that doesn’t mean we can get complacent in how we use water,” he said.

IN THE GARDEN WITH

NETAFIM

“Overwhelmingly, Western Australians heed the waterwise message. Since the early 2000s, average annual household water use across WA fell by 22 per cent. But lately, consumption w has risen.

“It’s crucial we don’t view desalination as a licence to waste water. While it’s a vital part of our water supply strategy, it will never replace the need to be waterwise.”

To reinforce this message, Water Corporation has launched a new campaign urging people to “break up” with their water-wasting habits ahead of summer. It is underpinned by research revealing one in five people are unaware of sprinkler rosters, while 64 per cent don’t know showers should be under four minutes.

“A longer shower or watering the garden outside of rostered days might seem insignificant at a household level, but it has a big impact to collective water supply,” said Mr Hambleton.

“Western Australians know the waterwise message better than most. But it’s time to be honest and ask ourselves if we’re still living that message every day.”

MINISCAPE

UWA Sports field Effluent and Bore Water Irrigation System

PROJECT OVERVIEW AND INTRODUCTION We were brought in on the project early by Western Irrigation as we do really well at more challenging systems as well as centralised irrigation systems, the flexibility of the Rainman system and our ability to customise when needed means there’s not too many situations where we cannot deliver a solution.

This project focuses on the sustainable irrigation of The University of Western Australia (UWA) sports fields using a combination of treated effluent and bore water. The initiative supports water conservation, environmental stewardship, and long-term cost savings while maintaining high-quality turf conditions for sporting activities.

• Wireless communication network for bore integration.

• Design and installation of an integrated irrigation system using effluent and bore water. Recycled water supplied by the treatment plant down the road and the 3 bores that are spread around the site.

• Infrastructure upgrades including cabinets, control systems, and bore control. One improvement requested was more integration with the bores, the previous system only had a pump start signal to the bore cabinets. The challenge with this is that the bores start was run over existing cabling and running new cables for the extra signals would have been very expensive. So we added a wireless IO network across the site that connects all the bores cabinets to the controller. This is a standard Rainman feature and allowed us to bring back fault signals, read the existing bore flow meters and send a reset signal if needed.

• Integration with Water Corporation Wastewater system.

• Weather station for automatic irrigation scaling in response to ET and Rainfall measurements • Soil Moisture – multi depth probe that shows water penetration through the soil profile

SCOPE, PLANNING, OBJECTIVES, AND BENEFITS Scope • Full control system design and integration.

• Installation of new infrastructure for Rainman Control System

24

THE OVERFLOW |

• Central control system – full management is available from the PC in the office, view alarms/events recorded by the system.

SPRING 2025

Objectives Improve system reliability and ensure uninterrupted irrigation: Reduce reliance on potable water. The previous system would run either the recycled water OR the bores for the program; the problem was that sometimes the recycled water would start or say that it was ready but then wouldn’t deliver and the whole cycle would be missed. At a high-profile site like this with events happening all the time, it’s difficult to catch up if the watering is missed.

Scope of Works Infield System: Installation of new cabinets and wiring the existing stations and pump signals.

Cabinet: New control cabinets with modular Rainman controllers.

Bores: Integration of existing bore infrastructure with fault monitoring and flow feedback.

Seamlessly manage multiple water sources: Improve irrigation efficiency and field performance. Automatically switch to the bores if the recycled water failed to deliver. This is trickier than it seems as there is a capacity mismatch between the water sources – the Recycled water system has almost twice the flow capacity of the bores. This was a major challenge of the design.

It needed to be a custom program feature in the controller.

Controllers: Smart irrigation controllers with remote access and scheduling. Central control system – full management is available from the PC in the office, view alarms/events recorded by the system.

First off, we couldn’t rely on the Water corp telling us that the recycled water was available. So to know for sure, we installed a new pressure sensor on the recycled water line, if the pressure is too low for too long that triggers the switch to the bores, this way it works is that when it needs to switch from the recycled water to the bores, it automatically runs the program for longer with less stations per group with the bores and ensures each station will runs for its full runtime.

Sensors: Pressure sensors, soil moisture probes, and weather station.

App: App for testing and checking faults.

Pumps: Efficient water delivery and pressure control based on the number of stations required to run.

This works because the controller has a feature that will automatically runs the required number of bores based on the flow requirement of the current group. So, it can switch and run seamlessly.

• Ensure compliance with environmental and health standards.

• Enhance monitoring and control capabilities.

• Minimise disruption during installation and commissioning.

Benefits Short-term: Reliable irrigation scheduling reduced manual intervention, improved turf quality.

Long-term: Cost savings, sustainability, and enhanced resilience to drought conditions. Automation and remote management from Computer or Phone

DESIGN PARAMETERS AND CONSIDERATIONS • Dual water source management: recycled effluent and three bores.

• Automatic switching logic based on real-time pressure/flow sensing.

• Flow capacity mismatch mitigation between recycled water and bores.

• Wireless I/O network to avoid costly cabling upgrades.

• Integration with Water Corporation’s strict operational requirements. Flow rate and pressure requirements.

• Zoning and coverage for sports field irrigation.

• Integration with existing infrastructure and future expansion capability.

• Compliance with Department of Health and environmental regulations.

• Remote Bore monitor and control like bore fault alarms and remote reset.

Project Timeline 2017–2021: Design development and proposal iterations.

2021–2022: Approval and mobilisation.

2022–2023: Infrastructure upgrades, cabinet fit-outs, and system commissioning.

2023–2024: Final integration, testing, and handover.

Ongoing: Integration Completed. Pending testing with Water Corp wastewater system due to safety and non-watering season. Need to complete the testing to finalise the automatic switching of bores and waster water system. Pending UWA approval for testing.

INSTALLATION METHODS • Western Irrigation carried out the infield installation, weather station, moisture sensors.

• Electrical Installation and integration • Commissioning of communications and remote mobile apps

KEY OUTCOMES AND LESSONS LEARNED

INSTALLATION SCHEDULE AND TIMELINES For us the project started late 2017, we were asked to propose a design for the control system. It was 4 years and 5 proposals later that the project got the go ahead.

We developed the control system for the project, supplied, installed, integrated all the new equipment, fit out the new cabinets, and developed the custom control features. The control system for this project is extensive.

• Successful integration of dual water sources with automated control.

• Importance of early stakeholder engagement and regulatory consultation.

• Need for flexible design to accommodate future upgrades and seasonal variations.

• Integration with external systems (e.g., hockey field irrigation) achieved via signal-based coordination.

• Water Corporation compliance achieved through multilayered safeguards and electrical lockouts.

• Wireless bore integration enabled fault monitoring and remote resets without new cabling.

ONGOING MAINTENANCE, TROUBLESHOOTING, AND CHALLENGES

Controller split in 2 – half the stations are connected to each cabinet – sensors connected to both cabinets. Easy to do with the modular nature of the Rainman system, split the controller in half using the comms link between the cabinets.

• Support with the SCADA and App maintenance.

• Controller faults and remote diagnostics.

• Regular monitoring of recycled water pressure and bore flow rates.

• One of the bores is shared with a separate system that runs irrigation over at the hockey fields nearby. The hockey system sends a signal to the Rainman controller to start which runs that bore and opens the master valve for that part of the line.

The system then logs when this is activated, and they can be sure that it is operating within its assigned window.

Challenges • • • •

Pavilion construction and site access constraints.

Bore cabinet upgrades and wiring identification.

Valve location and mapping.

COVID-related delays and stakeholder coordination.

FUTURE PLANS AND NEXT STEPS • Water Corp integration requirements were very extensive and a major challenge – they need 3hr preparation warning, 20 inhibits on their system to protect against misuse, and on our side we have an electrical lockout as a failsafe for the recycled water.

• Other challenges faced by the project include construction of the new pavilion, upgrades of bores cabinets, wiring identification, locating valves, minimising disruption, high profile project with many stakeholders, COVID lockdowns.

26

THE OVERFLOW |

• Expansion to additional fields and facilities.

• Enhanced analytics and reporting via central control system.

• Integration of predictive irrigation scheduling based on weather and soil data.

• Data logging and analytics for performance optimization.

• Continued collaboration with UWA sustainability and grounds teams.

Growing Strong Cultivating Mental Resilience in Your Irrigation Career

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!

W

orking in irrigation is rewarding but challenging, whether you’re managing complex agricultural systems, implementing urban irrigation projects, or leading install teams and businesses.

Regardless of your specific role, your mental resilience significantly influences your professional effectiveness, career trajectory, and overall satisfaction.

Mental resilience doesn’t mean avoiding stress or challenges; rather, it’s about developing the strength to navigate them effectively.

How do you currently balance professional advancement with your mental health?

MANAGING THE PROFESSIONAL AND PERSONAL BALANCE Training and professional development are foundational in any industry, including our own Irrigation Industry. There is a constant need for upgrading our technical skills, obtaining certifications, and specialising in niche areas like sustainable irrigation practices or introducing advanced technology

systems to communities. The commitment to ongoing learning, however, can result in significant stress when combined with daily professional responsibilities and personal life demands.

To manage we need to reflect regularly on our balance: Are our goals clear, or do we find tasks accumulating without a structured approach on how we will deal with them?

Effective time management involves setting realistic milestones and keeping focus on all those high-priority tasks. By scheduling structured breaks throughout the day, we can revitalise our energy levels. Brief, intentional breaks will refresh our mental energy and enhance our concentration resulting in a boost to overall productivity.

Additionally, it’s essential to communicate your workload and stresses clearly to your support network partners – colleagues, mentors, family, and friends. Being in a place where we can share openly about our professional demands helps reduce anxiety and creates a supportive environment that fosters greater understanding and assistance.

ADAPTABILITY AND EMOTIONAL INTELLIGENCE – EMBRACE IT! As Irrigation Professionals we often face continual shifts in technology, regulatory frameworks, and those ever-changing environmental conditions, making our adaptability essential.

We need to stop and ask ourselves: How comfortable am I with change?

Emotional intelligence (EI) is the ability to understand, use, and manage emotions positively. EI plays a critical role in helping us to navigate our way through workplace challenges and personal transitions.

We need to stop and ask ourselves: How comfortable am I with change?

Developing emotional intelligence involves finding our emotional triggers, empathising with others, and proactively managing stressors. Consider reflecting regularly on how effectively you engage with colleagues during challenging situations.

Are you empathetic, supportive, and clear in your communication? Cultivating EI not only enhances our adaptability but also significantly strengthens workplace relationships and teamwork.

RECOGNISING AND PREVENTING BURNOUT Burnout is increasingly common in high-demand fields such as our Irrigation Industry, characterised by seasonal fluctuations in workload intensity, and high expectations when critical farm infrastructure has broken down.

Let’s grab a moment to reflect: Are you experiencing persistent fatigue, lacking enthusiasm, or increased irritability towards tasks and interactions?

Early detection of burnout is crucial in preventing severe consequences. Taking structured, planned breaks helps – giving us time to check in with ourselves.

Creating firm professional boundaries is one of the most effective preventive measures in preventing burnout. Clearly delineate your work and personal lives, ensuring adequate rest and downtime. Incorporating healthy lifestyle practices – including regular physical exercise, balanced nutrition, and consistent sleep patterns – will substantially bolster your mental and physical resilience.

MINDFUL NETWORKING AND AVOIDING SOCIAL FATIGUE Networking events and industry gatherings play a significant role in career advancement. They provide opportunities to build connections, gain new insights, and for some of us, find new opportunities to further our career. However, frequent social engagements can lead to significant mental fatigue, and physical exhaustion.

Evaluate your social and networking habits: Do you typically leave events feeling exhausted rather than energised?

To avoid social fatigue, approach networking deliberately and strategically. Set clear goals before attending events and focus on building fewer, deeper connections rather than numerous superficial interactions.

Self-reflection for mental wellbeing Self-reflection will allow for faster recognition of issues and prompt corrective action.

Consider the following reflection points: • Am I consistently managing my professional and personal boundaries effectively?

• How satisfied am I with my workload and overall responsibilities?

• Am I keeping lifestyle habits that actively support my physical and mental wellbeing?

• Have I recently experienced signs of burnout or prolonged stress?

• Do my industry interactions and relationships generally energise or exhaust me?

• Am I struggling to maintain professional development?

Using a journal or digital app can make this process more effective and systematic, allowing you to track patterns and check progress over time. Regular self-reflection ensures you stay aware of your mental health status and can help you quickly respond to any issues.

SELF-REFLECTION AND PERSONAL RESILIENCE PLAN LEADERSHIP WITH EMOTIONAL INTELLIGENCE Effective leadership within the Irrigation Industry demands more than technical ability. It requires a deep understanding of emotional dynamics within teams. Leaders who regularly self-reflect by asking, “How am I impacting my team’s wellbeing and performance?” significantly enhance workplace culture and productivity.

INDUSTRY COMMITMENT TO MENTAL HEALTH Irrigation Australia has actively promoted mental health through initiatives like the “Let’s Talk About Mental Health” series and regular articles in the e-news. These initiatives underscore a sustainable commitment to enhancing awareness and fostering supportive workplace practices across our industry.

CHECK OUT AN INSTALL

Cultivating mental resilience requires ongoing conscious effort and reflection. Establishing a structured approach for regular self-check-ins will greatly enhance your chances for long-term resilience. Find a timeframe for self-reflection that works for you – Monthly is a good place to start and is particularly beneficial, some of us need to check in more frequently like weekly, others, well it varies on where they are at with their personal EI journey.

Mental resilience is integral not only for individual professionals but also for the health and sustainability of the broader Irrigation Industry. By prioritising personal mental wellbeing, engaging with industry support systems, and committing to ongoing reflective practice, you ensure a career that is rewarding, sustainable, and fulfilling.

Case Study

Yarra Yarra Golf Club Drives Down Energy Costs with HES Motor Package Project Overview Client: Bore Down Drilling / Yarra Yarra Golf Club Industry: Drilling and Pump Installation / Golf Course Management

BACKGROUND Bore Down Drilling is a trusted driller and pump installer in Victoria, working closely with clients to provide tailored water management solutions. One such client is Yarra Yarra Golf Club, one of Melbourne’s prestigious sandbelt courses, known for its commitment to maintaining premium turf conditions yearround.

THE CHALLENGE Faced with rising energy costs, Yarra Yarra Golf Club needed a solution that would allow them to maintain existing water flow levels without further straining their operational budget. The key challenge was gaining board approval for a more advanced pump system, which came with upfront costs – despite the promise of long-term savings.

THE SOLUTION Having already experienced strong performance and longevity from Franklin Electric’s bore pumps, Yarra Yarra Golf Club was open to exploring further improvements. Franklin Electric, in collaboration with Bore Down Drilling, proposed an upgrade to the High Efficiency System (HES) motor.

This recommendation was driven by the system’s proven energy-saving capabilities. To further enhance value, the club added remote access functionality and bore level monitoring – providing greater visibility and control over water management.

IMPLEMENTATION The solution was rolled out in a structured and collaborative process: • A site inspection was conducted to assess the existing bore pump system • A detailed proposal and quotation were prepared and presented to the board • Once approved, the system was installed within six weeks of order placement The partnership between Bore Down Drilling, Franklin Electric and the club’s board was instrumental in ensuring a smooth transition and successful deployment.

OBJECTIVES The primary goal was simple: retain the same water flow output while reducing annual energy costs. With a baseline power expenditure of $35,239 per year, the team set out to significantly lower this figure without compromising performance or reliability.

RESULTS The benefits were immediate and measurable. The club’s annual running cost dropped from $35,239 to $27,586 – delivering a saving of $7,652 per year. With these savings, the cost of the upgraded system was recouped in under 12 months.

Since then, the club has expanded the program, upgrading two additional bores with the HES Package. Combined, these upgrades are delivering approximately $17,000 in annual energy savings.

CONCLUSION & FUTURE PLANS Through smart investment in high-efficiency technology, Yarra Yarra Golf Club has achieved impressive energy savings while continuing to maintain their high turf standards. With three bores now upgraded and future-focused water management tools in place, the club is well positioned to manage costs and performance well into the future.

The club’s annual running cost dropped from $35,239 to $27,586 – delivering a saving of $7,652 per year. With these savings, the cost of the upgraded system was recouped in under 12 months.
