SNAPSHOT

The Nicholson Irrigation System (NIS), developed by Nicholson River Winery in East Gippsland, uses conventional drippers to deliver water directly to the plant roots via PVC pipe.

This method saves water by reducing watering time, evaporation, and weed growth.

It is easy to repair and maintain and lowers power and herbicide use.

A network of tensiometers to measure soil moisture complements the NIS.

NIS costs more than line irrigation at about $3.50 to $4 per plant, mainly due to labour; retrofitting is more expensive.

Half an hour to one hour is ample watering time with the NIS, and Ken, the vineyard manager, says it has reduced water use from 3 ML/ha to less than 1 ML/ha per year.

At Nicholson River Winery in East Gippsland, Victoria, irrigation has always been a balancing act –keeping vines healthy while making the most of limited water resources. After decades of using conventional drip irrigation, vineyard owner Ken Eckersley and his team set out to find a better way. They developed a new system that delivers water more efficiently, reduces evaporation, and promotes deeper root growth.

The Nicholson Irrigation Method: Delivering water straight to the rootzone

The irrigation system is easy to install, using plumbing components that are readily available. This article describes how they did it.

From rainfall to irrigation

The property has been producing wine for almost 30 years and relies on irrigation to supplement the variable 663 mm rainfall at Nicholson, in East Gippsland, Victoria.

The first vines planted relied solely on rainfall. Without irrigation, they established deep root systems, which helped them access water from deeper soil layers. According to Ken, these older vines are still producing the best fruit on the property.

Over time, as rainfall became less reliable, the vineyard installed drip irrigation to ensure a consistent water supply. In 2010, Jeff Paterson, Peter O'Keeffe and Ken Eckersley of Nicholson River Winery won first prize in the Southern Rural Water Waterwise award for groundwater users. The judges commended the system as being highly adaptable to other forms of agriculture.

However, they found that newly planted vines performed poorly. Extended drought, coupled with competition from summer grasses and inadequate water, resulted in plants with limited root development. These plants were also often diseased.

The Nicholson Irrigation System (NIS)

As a solution, the vineyard managers came up with the idea of combining conventional drippers with sections of PVC pipe to deliver water directly to the plant roots. This idea developed into what they call the Nicholson Irrigation System (NIS), which delivers water directly to the plant roots, is longlasting and ensures leaks and blockages are easy to fix.

The NIS combines the benefits of surface drip irrigation and subsurface irrigation. It uses 13 mm or 19 mm irrigation lines with pressure-compensation drippers located at each vine. Each emitter drips into a 40 mm PVC pipe that is inserted into the ground at the base of the plant.

Installation involves using a post-hole drill to dig to a depth of about one metre.

This loosens the soil to a depth of about half a metre below the PVC pipe to allow water to freely flow into the soil.

Gypsum can be added to clay soils to help improve soil structure during installation and to help with water penetration. The 60 cm length of PVC pipe is then inserted into the ground with 10 cm exposed above ground. The base of the PVC pipe is cut on an angle to reduce blockages during installation.

“In times of long-term rainfall decline, and rising costs, it can be the difference between viability and a slowly declining vineyard.”

Water where it is needed

The NIS delivers water directly to the plant's root zone rather than to the ground surface. This means less water is lost to evaporation and to competing grasses. Plant roots are also able to extend deeper into the soil rather than staying near the surface.

The NIS allows plants to quickly respond to added fertilisers or fertigation, although nutrients must be carefully applied to avoid burning the sensitive roots.

The introduction of the NIS has also been complemented with an extensive network of tensiometers to measure soil moisture.

NIS and soil types

The NIS also allows for a variation in dripper rates according to soil types. An unexpected benefit of installing the system is that the PVC pipe has provided a habitat for snails to collect in, which are then killed by baits.

Water-logging may be a problem with this system in some soil types. Installing the PVC pipe with an angled end, drilling the watering holes deeper than the PVC pipe and adding gypsum into the hole, can help to increase infiltration rates. The potential impact of water-logging can also be managed by varying the volume of water delivered to each plant by changing the rate at each dripper, based on soil type.

Benefits of installing NIS system

Installing the new system costs more than in-line irrigation at about $3.50 to $4 per vine. More than half of this is the labour

cost. It costs more to retrofit an existing line irrigation system as more labour is needed.

But according to Ken, it is a worthwhile investment. “In times of long-term rainfall decline, and rising costs, it can be the difference between viability and a slowly declining vineyard,” Ken said.

So far, the eight-hectare vineyard has had half of its 16,000 vines upgraded to receive water through the NIS. In future, Ken plans to automate the irrigation system with electronic valves and a timing unit, as half an hour to an hour is ample watering time with the NIS system. The original drip irrigation system took six to eight hours per watering.

Ken says there are huge savings to be made with the new system. “Our vineyard is a work in progress; however, there are indications that water use has reduced from three megalitres per hectare per year to one megalitre per hectare per year,” Ken said.

An introduction to passive irrigation

Instead of draining stormwater away, passive irrigation puts it to good use –sending it to green spaces where it helps keep cities cooler and greener.

Stormwater from rain and urban runoff is a free water source that can be redirected using gravity, making passive irrigation a low-cost, energyefficient solution.

These systems let water soak into the ground or move underground, reducing runoff, preventing erosion, and helping plants thrive.

Street trees struggle to get enough water in cities, but passive irrigation can help – though challenges like space constraints and maintenance need to be considered.

Wicking lawns store water underground, cutting evaporation, keeping grass greener for longer, and making better use of stormwater.

• Costs: Can be pricier than conventional landscaping. SNAPSHOT

As cities heat up in our changing climate, councils are looking for ways to keep urban areas cooler and greener. One approach is passive irrigation. Instead of treating stormwater as a problem to be drained away, this approach redirects it into vegetated areas using gravity – helping plants and trees thrive while reducing stormwater pollution.

Water sources for passive irrigation

Stormwater, including runoff from rain and roofs, is a key water source for passive irrigation. Instead of letting it rush down drains, we can put it to good use.

Here are some benefits:

• It is cost-effective and energy efficient. There’s no need for pumps or extra energy – gravity does the work.

• It helps keep cities cool and green. More water for plants means lusher, more liveable spaces.

• It reduces stormwater impacts. Slowing runoff improves water quality and reduces erosion in waterways.

There are many ways to incorporate passive irrigation into urban landscapes. Here’s a closer look at two key approaches:

Passively irrigated street trees. Urban street trees often struggle to get enough water, thanks to compacted soils and surrounding hard surfaces. Rainwater simply runs off roads and footpaths instead of soaking into the soil. That’s where passive irrigation comes in – diverting stormwater into tree pits with enough soil volume to support deep root growth.

But fitting street trees into existing infrastructure isn’t always easy. Common challenges include:

This article, based on Designing for a Cool City – Guidelines by the CRC for Water Sensitive Cities, outlines how passive irrigation can be designed, built, and maintained to keep urban landscapes greener, cooler, and more liveable. The article focuses on two approaches: passive irrigation of street trees and wicking lawns. Approaches to passive irrigation

• Space constraints: Underground pipes, powerlines, and street furniture can limit available space.

• Infrastructure conflicts: Roots and excess water might interfere with nearby footings or drainage systems.

• Road safety: Trees must be positioned to maintain clear sightlines.

• Maintenance needs: Vegetated landscapes require upkeep.

HOW DOES PASSIVE IRRIGATION WORK?

Passive irrigation systems channel stormwater from nearby surfaces into green spaces. The water can either soak in at the surface or be delivered underground, where it slowly rehydrates the soil and plant roots over time. The goal is to store and distribute water naturally, reducing the impact of hard, impermeable surfaces while supporting long-term plant health.

The best locations avoid clashes with existing infrastructure, but when that’s not possible, it might be necessary to reconfigure existing infrastructure.

Once the location of the street trees has been determined, the catchment area will then also be influenced by the crossfall of the street, the location of side entry pits and the roof drainage of adjacent buildings. The catchment area will have a large influence on the soil moisture of the system.

Wicking lawns. Unlike traditional lawns that rely on surface watering, wicking lawns have a built-in subsurface reservoir. Water moves upward through the soil via capillary action, meaning less evaporation and more efficient use of water. This setup provides a reliable source of moisture, keeping turf healthy and resilient while reducing the need for frequent irrigation.

Wicking lawns work best on flat surfaces (or terraced areas) but aren’t suitable for sloped landscapes. Their design is flexible, scaling from small home gardens to large sports fields. Unlike tree irrigation systems that prioritise soil volume, wicking lawns are shaped by landscape design needs and available space.

So, why choose a wicking lawn over a surface-irrigated one?

• The grass stays green all day: Since water is stored underground, there’s no need to schedule watering around public use.

• It’s a safe way to use stormwater: The separation between people and water reduces contamination risks.

• It’s highly efficient: No evaporation losses from sprinklers, and the turf only takes up the water it needs.

• It encourages deep root growth: Stronger roots lead to more resilient grass.

• It maintains even colour and density: Better visual appeal, with less patchy growth.

• It uses stormwater nutrients. Reducing the need for additional fertilisers.

Building passive irrigation into urban landscapes

Getting passive irrigation right takes careful planning. Civil engineers, landscape architects, and urban designers all need to work together to make it happen. Key considerations include:

• Construction timing: Passive irrigation features must be installed at the right stage in the process.

• Sediment and erosion control: Bypassing stormwater in the early phase can prevent clogging.

• Temporary irrigation: New plantings may need extra watering for the first couple of growing seasons.

Ongoing maintenance for long-term success

While passive irrigation is designed to be low-maintenance, regular care is still essential. Here’s what’s involved:

• Clearing debris and sediment: Preventing blockages that could reduce soaking into the soil.

• Managing plant densities: Infill planting where necessary to maintain system integrity.

• Weeding and pruning: Keeps plants healthy and visually appealing.

• Surface adjustments: Fixing minor soil displacement or erosion issues.

If larger problems arise – such as excessive sediment buildup, poor drainage, or plant failure – more significant maintenance might be needed. Keeping track of maintenance activities helps refine management strategies and ensures long-term performance.

Final thoughts

Passive irrigation is a smart, sustainable, and low-energy way to keep urban landscapes

green and cool. By making the most of stormwater, cities can improve plant health, reduce heat, and protect waterways – all while cutting down on unnecessary water use. As urban areas continue to grow, integrating passive irrigation into landscape planning will be crucial for building greener, more resilient communities.

Boosting citrus sweetness with less water

Finding the sweet spot

A recent study looked at how regulated deficit irrigation (RDI) can boost sugar levels in citrus for better flavour without hurting yields.

It found that March and April are the best months to apply RDI to balance sweetness with minimal fruit size loss.

Cutting irrigation by 50 per cent for eight weeks saved 0.77 ML/ha without harming tree health.

Troyer citrange rootstock saw greater size reductions than Poncirus trifoliata under RDI.

Afourer mandarins handled RDI well, but more research is needed for a bigger sugar boost.

Future trials will refine timing, explore clay soils, and test advanced imaging tech for monitoring.

Australian citrus growers need to produce fruit that meets consumer preferences while managing water efficiently. With Asian markets accounting for most of Australia’s citrus exports and favouring sweeter fruit, improving sugar content without reducing yield is a key challenge.

A recent Hort Innovation–funded research project, conducted by AgEcon, explored whether regulated deficit irrigation (RDI) could be used to enhance citrus sweetness while maintaining fruit size and tree health. RDI is not a new concept – it has been studied since the 1970s in crops like grapes and stone fruit – but advances in irrigation technology, soil moisture sensors, and stress monitoring tools have made it easier to apply with precision. By deliberately reducing water supply at key growth stages, growers can influence sugar accumulation in fruit while maintaining overall productivity.

The four-year study, carried out at the Dareton Primary Industries Institute near the Sunraysia district, tested this approach

on three navel orange varieties – M7, Washington Navel, and Lane Late – grafted onto two rootstocks, Poncirus trifoliata and Troyer citrange. The goal was to refine RDI timing and intensity to improve fruit quality while minimising negative impacts on fruit size.

How RDI affects fruit sugar and size

The study found that applying RDI in March or April increased sugar levels by 1–1.5 °Brix, a measure of sugar concentration in fruit juice that directly influences perceived sweetness. Earlier applications, in February, resulted in even higher sugar levels but also led to greater reductions in fruit size. On average, for every 1 °Brix increase, the proportion of large fruit (81–87 mm) decreased by 10 per cent. The effect was more pronounced in trees grafted onto Troyer citrange compared with those on Poncirus trifoliata, which were less sensitive to early water reductions.

To strike the right balance between sweetness and fruit size, the researchers

found that applying RDI in the first week of April worked best for Washington and Lane Late navels. This timing enhanced sugar content while limiting size loss, making it a practical option for commercial growers.

Water savings without sacrificing tree health

The RDI strategy involved an initial twoweek drying period until tree water stress reached 8–10 bar stem water potential, as measured by pressure chambers, and tensiometer readings exceeded -60 kPa at 30 cm soil depth. Irrigation was then reduced to 50 per cent for eight weeks before being restored to full capacity. This method saved 0.77 ML/ha over the RDI period without compromising tree health, making it a viable option for growers looking to improve water efficiency.

Looking ahead: Future research and applications

Additional trials on Afourer mandarins showed that RDI could increase sugar levels by 1 °Brix without noticeable effects on fruit size, suggesting it could be a promising

strategy for other citrus varieties. However, further research is needed to determine whether a 2 °Brix increase is achievable without affecting fruit quality.

The study also highlighted the influence of seasonal conditions. In wetter years, particularly in the Riverina, rainfall reduced tree stress, limiting RDI’s effectiveness. Future trials will explore RDI applications in clay soils, such as those at Curlwaa, NSW, to assess whether different soil types affect outcomes.

The research team also tested dronemounted thermal and multispectral cameras to detect canopy temperature differences between RDI treatments. However, temperature variations were minimal – less than 1°C – suggesting that more advanced thermal imaging technology may be needed to monitor tree stress effectively.

Recommendations

The final report for this project outlines a series of recommendations for citrus

growers that are intended as general guidelines developed from the four seasons of regulated deficit irrigation trial results on navel oranges.

It is suggested that growers test regulated deficit irrigation on a small scale of approximately 2–5 rows, including a control row, before it is extended to a full block of trees. The responses might vary due to different soil types, rootstocks, tree health, crop management practices and climatic conditions.

Aglantis’ AgTech Officer Barry Cross providing Ayr sugarcane farmer Andrew Castelanelli guidance on how to use Aglantis’ Smart Irrigation system

FROM GUESSWORK TO PRECISION: How AI and IoT are transforming water management

SNAPSHOT

Farmers have long relied on fixed irrigation schedules, leading to water waste, higher costs, and fertiliser runoff.

Smart-farming company Aglantis, and La Trobe University have been working together to develop a smart irrigation system that adapts to real-time conditions, cutting costs and improving sustainability.

Installed on an 80 ha sugarcane farm, it has saved veteran farmer Mark Castelanelli 15,000 km of travel per year.

Unlike other smart systems, this one is purpose-built for the sugarcane industry, reducing labour costs and increasing efficiency.

IoT sensors feed data into a digital twin, which automates irrigation based on soil moisture, temperature, and sunlight.

Future upgrades will add full automation, predictive maintenance, and intelligent sequencing to optimise water use further. 

BY GEMMA NARDONE

For decades, farmers have relied on fixed irrigation schedules –watering crops based on set times rather than real-time conditions. This often leads to wasted water, higher costs, and excess fertiliser running off into waterways, harming ecosystems like the Great Barrier Reef. But now technology is allowing irrigation systems to ‘think’ for themselves, responding dynamically to soil conditions and weather, and reducing risk.

That’s the idea behind a smart irrigation system developed by Aglantis in partnership with La Trobe University’s Cisco Centre for Artificial Intelligence and Internet of Things, directed by Cisco Research Chair, Professor Wei Xiang. Originally designed to reduce fertiliser runoff into the reef, the system has evolved into a cost-effective irrigation solution that helps farmers optimise water use, cut costs and improve sustainability.

Installed on an 80 ha sugarcane farm in Townsville, the system has been a game-changer for veteran farmer Mark Castelanelli, who used to drive 15,000 km a year to manage irrigation.

Mark said that while other smart systems had been on the market for a few years, this was the first that had been purpose-built for the sugarcane industry. He has found that the system saves labour costs, increases efficiency and leaves time to focus on other

things. The current set-up allows Mark to schedule irrigation for a full calendar year, and to adjust as he goes. Aglantis Managing Director, Luke Malan, said that the aim is to achieve full automation with the technology.

“The system turns on a pump, opens a valve, and combines that with sensor data to automate the process, saving water and electricity.”

How it works

Traditional irrigation follows fixed schedules, but this one responds to actual conditions in the field, using IoT sensors to measure soil moisture, temperature, and sunlight in real time. This data is fed into a digital twin – a virtual model of the farm’s irrigation system that mirrors real-world conditions. The digital twin continuously analyses the data, deciding when and how much to water, reducing waste and ensuring crops get exactly what they need.

Malan explains, “The system turns on a pump, opens a valve, and combines that with sensor data to automate the process, saving

water and electricity.” The system is compact and integrates a solar panel, sensors, an antenna, actuators, and a battery on a retractable pole.

While the system's validation capabilities were expected to be a key selling point, Malan has been surprised by farmers' positive response to the aerial view interface and its ease of use. Another standout feature, he said, is how the system reduces the need for soil probes. With the Aglantis setup, probes measure moisture levels based on soil type, rather than placing them in every block across the farm.

What’s next?

The first version of the system, developed in La Trobe’s Cisco Centre for AI and IoT and launched in December 2024, allows farmers to remotely control irrigation. The next phase will introduce full automation, integrating more data to prioritise irrigation sequences dynamically.

According to Professor Wei Xiang, further development will add features to improve productivity and crop yields.

Ultimately, the system could include intelligent sequencing to determine the perfect order of irrigation across different farm sections, predictive maintenance and continuous learning from historical data, seasonal patterns and crop responses.

SMARTER IRRIGATION, MORE FAMILY TIME: How technology is changing farming for the Tucks

Rob and Susannah Tuck operate ten farms in the Macquarie Valley in a 40 km radius near Narromine. They have a diversified mix of 5000 ha of dryland rotational cropping and between 1200 to 2000 ha cotton under irrigation, and a livestock enterprise.

Embracing technology

The Tucks are familiar with the advantages of technology and have been early adopters. They’ve been using GPS tracking in the controlled traffic management of vehicles in cropping areas, yield mapping as part of precision agronomy applications, monitoring sensors, and internet connectivity for some time.

Managing irrigation with technology

Managing irrigation involves constantly checking pumps. The sensors installed for this monitoring have provided great advantages. Previously, someone needed to drive to check pumps during the night and first thing in the morning to ensure they were operating correctly. Now, with the new system, staff can monitor the data remotely and travel only if there’s an issue, such as a pump shutting down. This improvement boosts safety, helps staff detect problems faster, and saves fuel and wear on vehicles.

However, although the pumps are constantly monitored, they are not controlled remotely. The sensors allow staff to view readings on a device, but they still need to do a regular physical check to verify the data. The sensors are also set up to send an alert signal to a mobile phone – for example, in the case of malfunction. The alert levels are adjustable for urgency.

Irrigation

system and sensor technology

The irrigation system is fully closed with a tail-return system designed to capture the water and prevent runoff. The sensors

monitor the system’s effectiveness, transmitting data to a dashboard to show if water levels are backing up or dropping. This allows the operator to adjust the pumps to control water flow at specific locations.

Adding cameras for extra peace of mind

In addition to the sensors, Rob has installed cameras that provide an overview of pumps, drains, channel heights, and sheds. The Tucks have a mix of connectivity with both Wi-Fi and 4G. These cameras do not replace the sensor data but offer a quick overview of the situation, acting as a backup to the sensors. Rob notes that cameras can also be used at night, offering additional peace of mind while systems are running.

Transitioning to pressurised irrigation

The Tucks have converted from a large floodirrigated area (manual with siphons) to an overhead pressurised system. This transition came with two significant advantages:

1. A consistent saving in the volume of water used, along with telemetry connections to monitor the performance of irrigation machines, allowing the operator to quickly address issues.

2. Telemetry also allows for better recordkeeping of the volume of water applied during the growing season.

Centralised data for better decision-making

All data, including that from weather stations and rain gauges, is sent to a dashboard on the office computer, where the platform converges it. This allows data from different providers to appear on the same screen for easy comparison.

The Tucks’ experience with technology

The Tucks have found that this technology allows them to:

• monitor remote devices from the phone, office, or kitchen table

• spend more quality time with family measure resource use for economic advantages to the business

• make more informed business decisions based on more data.

Professor

On farm trials show that VARIwise technology can save 10 per cent of water and increase productivity by 5 per cent in cotton and pasture farming.

The University of Southern Queensland (UniSQ) has received $1.5 million from the Australian Government to develop VARIwise commercially.

Associate Professor Alison McCarthy (recipient of the 2021 International Commission on Irrigation and Drainage (ICID) Irrigation Young Professionals WatSave Award) leads the research.

Initially, overhead and surface irrigation systems are expected to benefit the most and will be the focus of the new project.

Compatible with any irrigation system, VARIwise produces a suggested irrigation volume, day, and location that is universal across all systems.

The team will address barriers to widespread adoption through a lack of knowledgeable local consultants, by actively engaging tech-savvy irrigation consultants to work closely with growers and stakeholders at trial sites in Queensland, New South Wales, and Tasmania.

The next step for VARIwise is moving from research trials to whole-field evaluations while expanding its testing across more regions.

VARIwise is expected to be commercially available mid-2028.

WINS FOR COTTON AND DAIRY FARMERS from VARIwise’s smart irrigation control

 BY GEMMA NARDONE

Australia’s cotton and dairy industries will benefit from new technology that improves water efficiency and helps them adapt to climate change.

The University of Southern Queensland (UniSQ) has received $1.5 million from the Australian Government, in a project led and co-funded by Cotton Research and Development Corporation, to translate irrigation technology research into a commercial product. The technology, called VARIwise, is a precision irrigation system designed to improve how water is used on farms.

Associate Professor Alison McCarthy (recipient of the 2021 International Commission on Irrigation and Drainage (ICID) Irrigation Young Professionals WatSave Award) leads the research, noting that cotton industry water efficiency has increased by just 0.3 per cent annually. “VARIwise represents a step change in water use efficiency gains. The system ensures water is applied only when and where it is required, with the correct depth,” Associate Professor McCarthy said. This means that VARIwise could deliver a much larger and

more immediate improvement in irrigation efficiency, helping farmers better adapt to climate variability and production challenges.

Overview of the VARIwise design

VARIwise combines multiple data sources, such as soil, plant, and weather conditions, to determine the exact irrigation needs of a farm. Tests have shown it can save 10 per cent of water and increase productivity by 5 per cent in cotton and pasture farming.

On-farm demonstrations

In previous research, the team collaborated with cotton growers in Queensland and New South Wales and dairy farmers in Tasmania to develop and validate VARIwise. They conducted plot trials on commercial farms, comparing irrigation strategies – one that fills the soil-water deficit and another using optimisation algorithms, like VARIwise, to maximise water-use efficiency based on predicted yield. “This allowed us to verify potential water-use efficiency gains, incorporate grower feedback, and integrate commercially available irrigation control hardware, such as variable-rate irrigation and infield sensors,” said Associate Professor McCarthy.

Associate

Alison McCarthy who is leading the new Climate Smart project with coinvestigator Associate Professor Joseph Foley.

Initially, overhead and surface irrigation systems are expected to benefit the most and will be the focus of the new project. However, Associate Professor McCarthy said that the optimisation process in VARIwise is compatible with any irrigation system, producing a suggested irrigation volume, day, and location that is universal across all systems.

The challenges

A key barrier to widespread adoption of advanced irrigation control technology is the availability of knowledgeable local consultants to support growers on-farm. The team will address this by actively engaging tech-savvy irrigation

consultants who will work closely with growers and stakeholders at trial sites in Queensland, New South Wales, and Tasmania. The outcomes will be shared with industry stakeholders, including growers, consultants, and irrigation technology providers – through extension activities.

Next steps

The next step for VARIwise is moving from research trials to whole-field evaluations while expanding its testing across more regions. “This will lead to full-scale commercial deployment, and we expect VARIwise to be available in a commercialready package by project completion in mid2028,” said Associate Professor McCarthy.

As projects such as the proposed Wyangala Dam expansion demonstrate, Australia can no longer afford to gamble its water future on outdated, costly and environmentally destructive solutions. It’s time to end the wasteful spending.

In Australia and worldwide, big dam cost overruns can be up to 825 per cent. The average overrun is 120 per cent. Public costs for private gains are a major concern.

The fixation on building and expanding dams means innovative alternatives are often ignored. These other options include recycling water, managing demand and carefully recharging aquifers (using aquifers as underground dams).

The National Water Grid Fund exemplifies the misguided “build more dams” mindset. Its portfolio of 61 large water projects has a total capital cost estimate of up to $10 billion. Only 23 of these projects have publicly available business cases. More than $1.7 billion in committed funding is shrouded in secrecy.

To avoid repeating costly mistakes and mismanaging taxpayers’ money, we need a smarter approach to major water projects. This includes independent assessments and greater transparency, with business cases made public and decision-making open to scrutiny.

Infrastructure planning must account for long-term climate impacts on water availability. Planning for climate change is vital

Why building more big dams is a costly gamble for our future water security and the environment

Climate change and biodiversity loss are mounting threats to Australia’s water security. So we often hear calls for more dams. But is that the answer? Our recent research reveals large dam projects are costly gambles with public money. They often fail to deliver promised economic benefits. They also have major environmental, financial and social impacts.

In New South Wales, some members of the Lower Lachlan River community were concerned about plans to expand Wyangala Dam. They first asked us in 2020 to investigate its full costs and benefits, with findings presented at a local workshop in 2022.

The first WaterNSW estimate of capital and operating costs was A$620 million in 2018. Within a few years, it had soared to as much as $2.1 billion. In 2023, the project was scrapped because it wasn’t economically viable.

Similar concerns surround other projects overseas and in Australia, including Hells Gate Dam in Queensland, and Dungowan Dam and Snowy Hydro 2.0 in NSW.

Lessons from past mistakes

Inadequate economic assessments of big dam projects are a global problem. The Grand Ethiopian Renaissance Dam and India’s Subansiri Lower Hydroelectric Project promised big, but had rising price tags and devastating impacts on ecosystems.

In Australia and worldwide, big dam cost overruns can be up to 825 per cent. The average overrun is 120 per cent. This casts serious doubt on such projects’ financial and social viability. Public costs for private gains are a major concern.

Our study reviewed the original business case for the Wyangala Dam expansion. The original study had concluded there would be net social benefits and gave the project the green light.

Our review found the business case was seriously flawed. It overestimated benefits and grossly underestimated physical capital and environmental costs. Estimated building costs blew out by 239 per cent. If the project had gone ahead, the costs would undoubtedly have increased.

On top of this, assessments of impacts on rivers and wetlands were poor and superficial. They greatly undervalued the environmental effects of expanding the dam, particularly on downstream wetlands.

On the other side of the equation, its benefits were overblown, particularly for water security and agriculture.

Local voices believed many of their concerns had been ignored. There were deep concerns that flood-dependent farmers downstream might lose some of their livelihoods. Indigenous communities were worried about their cultural sites being destroyed.

Our analysis provided a more rigorous assessment of benefits and costs of the Wyangala Dam expansion.

We found total project costs were underestimated by at least 116 per cent. The benefits were inflated by 56 per cent. This meant the true impacts on the environment, agriculture and local communities were misrepresented.

Rethinking Australia’s water future

Our analysis provides a salutary lesson on why we need to rethink water security. Instead of sinking billions into dams, we should find smart and sustainable ways to manage our water.

The National Water Grid Fund exemplifies the misguided “build more dams” mindset. Its portfolio of 61 large water projects has a total capital cost estimate of up to $10 billion. Despite this massive investment, only 23 of these projects have publicly available business cases. It leaves more than $1.7 billion in committed funding shrouded in secrecy.

This lack of transparency is alarming, given the history of cost overruns and inadequate assessment of environmental damage. It points to the urgent need to reassess our approach to water security. The public has a right to know that their governments are spending wisely.

To avoid repeating costly mistakes and mismanaging taxpayers’ money, we need a smarter approach. Independent business cases should be mandated for all major water projects.

In Australia and worldwide, big dam cost overruns can be up to 825 per cent. The average overrun is 120 per cent.

We also need a strong public sector capable of transparent evaluation. Promised new National Environmental Standards as part of reforms to environmental protection laws are likely to require rigorous scrutiny too. We must embrace transparency by opening decision-making to public scrutiny and diverse perspectives, including local voices and Indigenous stakeholders, from the start.

Finally, infrastructure planning must account for long-term climate impacts on water availability. Planning for climate change is vital.

Instead, we need to channel our efforts into truly effective, sustainable and transparent water management. Strategies must give priority to community needs, First Nations’ water rights, environmental protection and longterm climate resilience.

In 2021, Think Water Darwin was engaged to install an irrigation system as part of The Water & Carbon Group’s leachate treatment project at Shoal Bay Waste Management Facility.

This project was unusual because the purpose of irrigation was to manage wastewater rather than support plant growth, with vetiver grass absorbing treated leachate.

Key challenges included steep terrain, leachate contamination, and wind erosion, requiring a customised irrigation solution.

A 176 m centre pivot system with low-mounted sprinklers was installed to ensure even water distribution and minimise losses.

A Valley control system and telemetry automated irrigation, enabled remote operation, and allowed the system to shut down if faults occurred.

All pipes were lined with PVC to resist corrosion, and a Southern Cross Star Pro pump handled high-pressure operation.

The system operates daily in the dry season, working in sync with the treatment plant in a closed-loop wastewater management process.

CASE STUDY: designing an irrigation system for landfill leachate

When we think of irrigation, we usually picture systems designed to deliver water efficiently to support plant growth. But at Darwin’s Shoal Bay Waste Management Facility, irrigation serves a different purpose. Here, the end goal isn’t to grow plants – it’s to manage wastewater, with plants as part of the solution. Vetiver grass, planted atop a capped landfill, acts as a living filter, absorbing treated leachate that would otherwise pose a toxic risk to the environment.

In Darwin’s northern suburb of Karama, the Shoal Bay Waste Management Facility is the central hub for waste and recycling operations, processing over 180,000 t of waste every year in a unique tropical climate.

The facility faced the challenge of managing leachate – wastewater generated within landfill. Leachate contains contaminants, including PFAS (Perfluoroalkyl and Polyfluoroalkyl Substances), toxic ‘forever chemicals’ found in everyday products such as cleaning and personal care products. Darwin’s high rainfall and limited

evaporation exacerbate the problem by allowing leachate to accumulate.

Irrigation to manage toxic wastewater

In 2021, Shoal Bay engaged environmental engineering firm The Water & Carbon Group (Water & Carbon) to construct a leachate treatment plant to treat more than 50 ML per year of leachate.

The first stage of the treatment process is the extraction of PFAS using Water & Carbon’s patented LEEF System®. This is followed by a biological treatment process, which is an important part of the treatment train dealing with ammonia, nutrients and heavy metals. The final stage involves a surface flow (polishing) wetland before using the treated leachate to irrigate a 6.5 ha site on top of the capped landfill cells, planted with vetiver grass.

Irrigation for a different purpose

Unlike conventional irrigation systems designed primarily to support plant growth, this system was built to manage and dispose of treated wastewater through plant uptake. The vetiver grass acts as a natural filtration and absorption system, removing contaminants while creating a zero-liquid-discharge, closed-loop treatment solution.

“Irrigation is a critical step in the treatment process,” said Jim Hunter, CEO of Water & Carbon. “Without it, there would be no viable way to manage the treated wastewater, as there are no available discharge pathways to the environment.”

Water & Carbon engaged the Think Water Darwin team to design and install the irrigation system for the site.

“This was a fascinating job,” said Adam Stockwell, managing director of Think Water Darwin. “While the irrigation system design itself was fairly standard, the project was anything but. We weren’t just irrigating crops or turf – we were dealing with toxic wastewater on a capped landfill site on steep terrain, which subsides over time. That meant we had to carefully consider how the system would perform over time.”

This specialised purpose required a custom irrigation system capable of delivering water precisely while adapting to the site’s environmental constraints. The system

operates automatically, working in sync with the treatment plant. Irrigation rates are adjusted based on weather conditions, such as rainfall, high winds, or extended dry periods, to optimise water use and prevent over-application.

In the early years of operation, the facility did not harvest the vetiver grass, allowing it to establish and provide ground cover for erosion control. “Now that the grass is well established, we expect to harvest it annually,” Jim said. “We’ll also test the plant tissue to determine whether the harvested material can be used as general mulch.”

“While the irrigation system design itself was fairly standard, the project was anything but. We weren’t just irrigating crops or turf – we were dealing with toxic wastewater on a capped landfill site on steep terrain, which subsides over time. That meant we had to carefully consider how the system would perform over time.”

The irrigation system

Design challenges. The Think Water Darwin team designed and installed an irrigation system to deliver 8 mm a day of treated leachate to the vetiver grass site.

The main design challenges that the team faced were:

• the steep terrain of the site to be irrigated, and its elevation – the water had to be pumped up 40 m from the wetland below

• water quality issues due to leachate contamination

• the effects of wind and erosion on the mounds over time.

Centre pivot. The Think Water Darwin team designed and built a customised irrigation system to pump the leachate to the top of the disposal site and irrigate the vetiver grass with a centre pivot.

WHAT IS VETIVER GRASS?

Vetiver grass (Chrysopogon zizanioides) is a hardy, deep-rooted, perennial grass native to India but now cultivated worldwide for various uses. It is commonly used for erosion control, soil stabilisation, water conservation, and phytoremediation due to its extensive root system, which can reach depths of up to 3–4 m.

To ensure even water distribution in windy conditions, the team selected a 176 m Pierce CP600 centre pivot fitted with Nelson R3030 sprinklers. These sprinklers, mounted on drop tubes positioned close to the ground, minimise wind drift and evaporative losses. The system also produces larger water droplets, which are less prone to drifting in strong winds, ensuring water reaches the intended area.

A Valley control system was installed, allowing operators to customise irrigation rates for different sections of the site. The system also controls the end gun, enabling targeted irrigation where needed. Telemetry provides additional automation, allowing the system to switch to a potable water source for flushing, detect malfunctions, and shut down when necessary.

To accommodate grass harvesting and extreme weather events, the pivot includes a manual mode, making it easy to move out of the way during maintenance or secure it before a storm.

The system operates every weekday during the dry season, ensuring consistent irrigation of the treatment plant’s output. Operators control the entire system remotely via a mobile app, streamlining management and reducing the need for onsite adjustments.

Pipes and pump. Leachate is highly toxic and corrosive, requiring specialised materials for durability and safety. To prevent corrosion and extend the system’s lifespan, all pipes, including those in the centre pivot, were lined with PVC, while the pump was fitted with silicon seal faces for added protection.

A Southern Cross Star Pro pump (model 80x50-160), powered by a 15 kW WEG motor, was installed to transfer water to the site. It delivers 40 m³ per hour at a head height of 54 metres, with water transported through 160-mm pipes rated for 10-bar (PN10) pressure.

Telemetry was added as a necessary safety measure, allowing the system to shut off the feed pump automatically if a fault occurred. Although not part of the original design, it was essential for handling leachate safely and was integrated with the Valley control system.

A sustainable, closed-loop solution

This project highlights how irrigation can play a role beyond agriculture and turf – helping to safely dispose of treated

The centre pivot irrigation system was designed by the Think Water Darwin team to distribute treated leachate efficiently while minimising wind drift and evaporation.

HOW GOULBURNMURRAY WATER met its 2025 emissions target ahead of schedule

 BY EVE WHITE, IRRIGATION AUSTRALIA

Victoria’s 18 water corporations have committed to 100 per cent renewable electricity from 2025 and net-zero emissions by 2035.

Since 2019–20, sector-wide emissions have fallen by 19 per cent, equivalent to taking 78,000 cars off the road.

This article describes how GoulburnMurray Water (GMW) reduced emissions to below its 2025 target ahead of schedule.

GMW’s transition includes large-scale solar and battery storage and fleet electrification.

Each water corporation needs to take a different approach to reducing emissions, and extreme weather and rising energy demand pose challenges to maintaining long-term emissions reductions.

Solar panels on one of Goulburn-Murray Water’s flume gates.

Victoria’s 18 water corporations are working towards ambitious emissions reduction targets, having committed to 100 per cent renewable electricity by this year and net-zero emissions by 2035. In 2019–2020, the sector produced nearly one million tonnes of carbon emissions – equivalent to the emissions from 410,000 passenger vehicles over a year. Since then, emissions have fallen by 19 per cent, a reduction comparable to taking 78,000 cars off the road.

While the sector still has progress to make, seven water corporations have already surpassed their 2025 emissions targets, including Goulburn-Murray Water (GMW). This article examines how GMW achieved this.

Goulburn-Murray Water is Australia’s largest rural water corporation, covering an area the size of Tasmania. It delivers water to about 25,000 customers and manages 11 million ML of water storage. Keeping water flowing across such a vast area takes large amounts of energy, particularly for pumping.

To meet Victoria’s 2025 renewable electricity target, GMW committed to sourcing 100 per cent renewable electricity, cutting its total emissions by 75 per cent. This reduction accounts for electricity-related emissions, while some remaining emissions sources, such as fuel use and infrastructure operations, will require further action to reach net zero by 2035.

Goulburn-Murray Water’s Business and Finance General Manager Michael Gomez emphasises that emissions reduction efforts must also be financially responsible. “At GMW, we make sure that any initiatives to reduce emissions are commercially viable. Installing solar at our offices comes with an initial expense, but these expenses are offset within a few years due to reduced power fees,” he explains. “Similarly, purchasing electric vehicles and installing charging stations at our offices reduces long-term expenditure on fuel.”

Solar and battery storage powering irrigation

A key initiative in GMW’s transition is the Mitiamo Pump Station and Stock and Domestic Pipeline, a 300 km pipeline

“Installing solar at our offices comes with an initial expense, but these expenses are offset within a few years due to reduced power fees.”

servicing 58,000 ha of farmland. A 99.7 kW solar array and a 404 kWh battery system now power the pumps, ensuring operations even in low-sunlight conditions. Over 25 years, the system will generate 3.9 gigawatt-hours of clean energy, significantly cutting emissions.

As well as the Mitiamo transition, GMW is also:

installing solar panels at its Tatura headquarters, home to 200+ staff

• planning to roll out solar at four more offices during 2025 using hydropower to harness energy from water movement at multiple water storages

• investigating how pump scheduling can be optimised to act as a ‘solar sponge’, using surplus solar power from the grid.

Decarbonising the vehicle fleet

GMW’s vehicle fleet has also been a major emissions source. To address this, it is shifting to low-emission and electric vehicles:

The SUV fleet is primarily made up of hybrid vehicles.

• The first electric vehicle (EV) was added in 2023, with a charging station installed at Tatura.

• More EVs and charging stations are planned for 2025 at four additional locations.

Target: A fully zero-emission fleet by 2030, pending the availability of electric utilities.

Goulburn-Murray Water is also closely monitoring developments in electric utilities and other low-emission transport options to ensure it can meet its long-term sustainability goals.

Climate change and long-term challenges

While GMW and other Victorian water corporations have made progress, many still have considerable reductions to make to reach their 2025 targets, according to a recent report. Even once targets are met, with rising electricity demand and climate-related disruptions, maintaining emissions reductions long-term will remain an evolving challenge.

• Extreme weather events, such as flooding, can disrupt infrastructure, increase energy demand, and reduce the effectiveness of on-site renewable generation.

• Some corporations are experiencing rising electricity consumption, which could outpace their investment in renewables.

• Meeting the 2025 and 2035 targets will require continued investment in renewable energy, efficiency measures, and climate resilience strategies.

While the 2025 and 2035 targets are clear milestones, GMW continues to monitor market trends and emerging technologies to ensure long-term sustainability. Gomez says the organisation remains committed to seeking out new solutions: “We constantly monitor the market for any trends and innovations that could support us in further reducing emissions.”

Each water corporation faces different challenges and opportunities, meaning their approaches and timeline to net zero will vary.

Meeting the 2025 and 2035 targets will require continued investment in renewable energy, efficiency measures, and climate resilience strategies.

UNDERSTANDING SCOPE 1, 2, AND 3 EMISSIONS

Scope 1 emissions – Direct emissions from sources a company owns or controls. For water corporations, this includes:

emissions from fuel use in company vehicles and machinery

• methane and nitrous oxide released during wastewater treatment processes.

• on-site gas combustion (e.g., in backup generators or heating systems).

Scope 2 emissions – Indirect emissions from purchased electricity used by the company.

• Most emissions in Victoria’s water sector come from electricity used for water pumping and treatment.

• The push for 100 per cent renewable electricity by 2025 is primarily focused on eliminating Scope 2 emissions.

Scope 3 emissions – Indirect emissions from a company’s supply chain, including:

emissions from suppliers and contractors (e.g., emissions generated in producing materials for infrastructure projects).

• waste disposal and landfill emissions

• business travel and other indirect operational impacts.

WHAT IS VICTORIA’S WATER SECTOR FOCUSING ON?

Victoria’s water corporations are prioritising reductions in Scope 1 and 2 emissions, particularly:

Scope 1 emissions – These are harder to reduce, but efforts include:

• replacing fossil fuel-powered vehicles with electric vehicles (EVs)

• using biogas from wastewater treatment to generate electricity

• optimising pumping schedules to reduce energy consumption.

Scope 2 emissions – By switching to 100 per cent renewable electricity by 2025, these emissions will be effectively eliminated.

Scope 3 emissions are not currently required under the Statement of Obligations (Emission Reduction), but some corporations are beginning to track and report them. Initiatives such as Yarra Valley Water’s carbon in construction tool suggest a potential future shift towards addressing Scope 3 emissions.

Industry programs are currently leading the way in recycling plastic irrigation products. Photo from this video about circularity in resources by Rivulis.

Plastic plays a crucial role in modern farming, from mulch films to irrigation tubing, but its end-of-life management presents a challenge.

This article explores two strategies for tackling agricultural plastic waste: finding alternatives where possible and improving recycling systems for plastics that can’t be replaced.

Biodegradable mulch films and organic alternatives are emerging as replacements for plastic mulch, helping to reduce waste while maintaining soil health.

Drip irrigation recycling programs help growers recycle used drip lines and drip tape instead of sending them to landfill.

PVC irrigation pipes can last over 100 years and are highly recyclable. Initiatives led by PIPA and major manufacturers are working to increase recovery rates and reuse in new products.

Despite progress, challenges remain, including high collection costs, inconsistent recycling availability, and limited national coordination.

Industry leaders stress that while recycling is vital, it should be the last resort – the focus should be on reuse, longevity, and sustainable product design.

AGRICULTURAL PLASTICS: Can we replace, reuse or recycle?



BY EVE WHITE, IRRIGATION AUSTRALIA

Plastic is woven into almost every aspect of modern farming. From mulch films that suppress weeds to drip irrigation tubing that conserves water, plastic has enabled agriculture to become more efficient and productive. But while plastic plays a critical role in food production, its end-of-life management poses a significant challenge. What happens to plastic once it’s no longer useful? And what are the alternatives?

The problem with on-farm plastic waste

Plastic removal isn’t just an environmental concern; it’s also an economic one. The cost of removing, transporting and disposing of plastic can significantly eat into a grower’s bottom line. Removing plastic mulch can also result in valuable topsoil loss, undermining soil health and productivity.

This article explores two key approaches to managing agricultural plastic waste: finding viable alternatives to plastic where possible and improving recycling systems for plastics that cannot yet be replaced. The sections below examine solutions for plastic mulch, irrigation tubing, and PVC piping, along with industry-led recycling initiatives.

Alternatives to plastic mulch

Plastic mulch is widely used in agriculture. It helps retain moisture, suppress weeds, and improve crop yields. However, its disposal presents ongoing challenges, from high removal and landfill costs to the risk of plastic contamination in soil and waterways. There is also a risk of plastics breaking down into microplastics and entering the food chain. As concerns about plastic waste grow, many farmers are exploring alternative solutions that offer similar benefits without the long-term environmental impact.

To address the issue, growers are exploring alternatives that are both cost-effective and environmentally friendly. Two primary options stand out: organic mulches and certified soil biodegradable mulch.

Organic mulches. Organic materials, such as straw, wood chips, and cover crops, provide natural weed suppression and soil protection.

• Straw mulch helps retain soil moisture and prevent erosion but does not provide the same warming effect as plastic mulch.

• Wood chips contribute to long-term soil health by enhancing organic matter but must be sourced carefully to avoid contamination.

Living mulch (cover crops) can provide additional benefits, such as nitrogen fixation and pest deterrence, though they require careful management.

Certified soil biodegradable mulch.

A growing alternative is certified soil biodegradable mulch, which is designed to break down naturally in the soil. Unlike conventional plastic mulch, which must be collected and disposed of, this mulch decomposes into carbon dioxide, water, and biomass through microbial activity. However, it’s important to verify that products meet the ISO 23517 certification, as some so-called biodegradable plastics simply fragment into microplastics instead of fully degrading.

Plastic mulch is useful for retaining moisture, suppressing weeds and improving yields in many crops but farmers are increasingly exploring alternative solutions.

Cost is an important factor to consider. While certified soil biodegradable mulch has a higher upfront cost than conventional plastic mulch, it eliminates removal and disposal expenses. Studies indicate that when factoring in labour and transport costs for plastic mulch disposal, biodegradable alternatives can become more cost-effective over time. Growers should assess the full lifecycle costs before making a decision.

Beyond mulch: Managing other agricultural plastics

While viable alternatives exist for plastic mulch, other agricultural plastics, including irrigation tubing and pipes, are not as easily replaced. In these cases, recycling is the best available solution, with industry-led programs helping to manage plastic waste in essential applications.

Recycling solutions for agricultural plastics

Drip line and drip tape recycling. Netafim’s ReCoil Program, running since 2006, provides a recycling pathway for growers to return used drip line, preventing waste from accumulating on farms. Growers collect used drip line and use Netafim’s ReCoil retrieval machine to prepare it for transport. The recoiled material is then sent to recycling partners for processing, and growers receive a Certificate of Recycling once it has been recycled. To further close the loop, Netafim’s ReGen program incorporates recycled plastics, including old dripline, into new irrigation products – reducing reliance on virgin plastics.

Rivulis also runs a recycling service, supporting growers in the Lockyer Valley, southern NSW, Victoria, South Australia, and more recently, Bundaberg. Growers can stockpile used drip tape on-farm, where a recycling operator arranges collection. To improve processing efficiency, tape should be separated from plastic mulch. In February this year, 40 t of trickle tape were collected from the Bundaberg Waste Management Facility for recycling into new irrigation products.

PVC pipe recycling. Executive general manager of the Plastics Industry Pipe Association of Australia (PIPA), Cindy Bray, emphasises that not all plastics are the same. “Unfortunately, ‘plastics’ is a term that is generalised, when in fact there are many different types and not all of them have the characteristics or physical properties of single-use plastics.”

PVC pipes are designed for service lives of more than 100 years and at the end of their useful life, they can be reused and recycled, with studies showing that PVC pipes can be recycled up to 10 times.

“Although recycling is important, in a circular economy recycling is the last resort. We want products to stay in use for as long as possible, then be repaired and reused, and then recycled.”

The Plastics Industry Pipe Association of Australia plays a crucial role in promoting best practices for PVC recycling within the irrigation and construction industries. By collaborating with manufacturers of PVC pipes and fittings who have established recycling programs, PIPA supports sustainable waste management solutions for agricultural plastics.

Plastic pipe manufacturers such as Vinidex, Pipemakers, Australian Plastic Profiles, David Moss Group and Iplex (Pipeback) with their recycling initiatives, have established

collection points for PVC irrigation pipes and fittings. These programs provide a pathway for materials to be processed, rather than being sent to landfill.

"However, due to their long lifespan, there is often a low and inconsistent volume of material available. “Our industry is always looking at ways to work collaboratively with waste management companies, major distributors, and suppliers to collect viable volumes of plastic pipes for designated recycling,” Bray explains.

The industry is already advanced in incorporating recycled material into pipes, with technology enabling manufacturers to use up to 95 per cent recycled content in the inner core of PVC non-pressure pipes. “We want to ensure plastic pipes manufactured with recycled content perform just like a pipe made from virgin material – durability and performance are critical,” Bray notes. “Although recycling is important, in a circular economy recycling is the last resort. We want products to stay in use for as long as possible, then be repaired and reused, and then recycled.”

The future of agricultural plastics

Australia's 2024 goals for circular economy and waste management are shaping how plastic waste is handled across many industries, including agriculture. But progress on recycling agricultural plastics has been patchy, with efforts advancing in some areas while stalling in others.

Grieg Graham, managing director of Rivulis Irrigation, notes that while industry programs provide recycling options for materials like drip irrigation equipment, a coordinated national approach remains difficult.

According to Dr Anne-Maree Boland, principal at RMCG, extended producer responsibility – where producers are held accountable for the environmental impact of their products across their entire life cycle – could be a long-term solution for managing agricultural plastics more sustainably. In the meantime, regional and industryled initiatives are stepping in to help. Dr Boland pointed to local governments such as Southern Downs and Bundaberg Regional Councils in Queensland and Swan Hill Regional Council in Victoria, which are working with local growers to support plastic recycling on the ground.

A cucumber farmer in Western Australia set out to improve its irrigation system, overcoming challenges with climate, single-phase power, and investment capacity.

Great Northern Rural Services (GNRS), a Geraldton-based rural water specialist, collaborated with Davey Water Products to recommend a solution.

Instead of installing an electric pump, a petrol-powered pump was used, achieving the required flow and pressure.

No adaptations were necessary, apart from sufficiently sized pipework in/ out of the pump, which is started and stopped manually.

The pump has the ability to be mobile, and run various applications, making it versatile for use.

Maintenance requirements align with existing service schedules for other small engines on the property.

The pump currently uses a mix of mains and dam water from tanks, with plans to capture rainwater as the primary source in the future.

This case highlights the importance of practical irrigation solutions for growers facing budget and infrastructure challenges; and the value of collaborating with local specialists who understand regional conditions and the technical aspects of water management.

study: Cucumber

grower

finds irrigation solution without costly upgrades

When a cucumber grower in Geraldton, Western Australia, set out to improve their irrigation system, they faced a major hurdle: their farm’s existing infrastructure only supported single-phase power. Supplying enough water to multiple hot houses required a high-capacity pump capable of delivering 800L/min at 300 kPa, but standard electric pumps with that level of performance typically require three-phase power. Upgrading the farm’s electrical system would have been an expensive and time-consuming undertaking.

At the same time, the farm’s irrigation equipment needed to withstand the harsh conditions of the Mid-West WA climate, where heat, wind, and dust can put extra strain on outdoor machinery.

Finding a practical pumping solution

To meet the grower’s needs without major infrastructure costs, Great Northern Rural Services (GNRS), a Geraldton-based rural water specialist, collaborated with Davey Water Products to explore alternative solutions. Instead of installing an electric

pump, they recommended the petrolpowered Davey 5113HE FireFighter pump, a 13HP single impeller model capable of achieving the required flow and pressure.

By using a petrol-driven system, Aidan Gregan, Territory Manager for Davey Water Products, explained that the grower could achieve reliable irrigation without modifying their electrical infrastructure. He said that no adaptations were necessary, apart from sufficiently sized pipework in/out of the pump, which is started and stopped manually.

The pump’s design also provided the durability needed for the demanding local climate. “With the installation being new, the lack of existing infrastructure meant that the output of this pump vs investment required to set up, was favourable,” Gregan said.

Installation and system performance

Since installation, the new pump has consistently met the grower’s irrigation

requirements, ensuring a steady water supply to the hot houses without performance issues. The ability to bypass the need for three-phase power has not only saved the grower a significant upfront investment; it also provided flexibility for future expansion.

The pump has the ability to be mobile, and run various applications, making it versatile for use on this property. The impact on water efficiency and crop health, Gregan said, is the ability to run a large amount of irrigation with one asset, and vary the output based on requirement at any given time. Currently, the pump is fed by water tanks, drawing a mix of mains and dam water. Future plans aim to capture rainwater, and for this to become the dominant water source.

Regarding maintenance, Gregan said that the pump will align with existing schedules for checking other small engines on the property.

Lessons for other projects

This case highlights the importance of practical irrigation solutions for growers facing budget and infrastructure challenges. It also highlights the value of collaborating with local specialists who have a deep understanding of both regional conditions and the technical aspects of water management.

Power infrastructure limits many operations, especially those lacking provisions for three-phase power, said Gregan. “Single-phase even has limitations for pump sizing, as factors like amp draw need to be considered. Larger operations

may have three-phase power, but growing operations may not be in a position to invest in such infrastructure, while expanding. These types of solutions can be crucial for developing operations.”

When comparing electric vs. petrolpowered irrigation pumps, Gregan noted that both petrol and diesel-powered pumps offered versatility, mobility, and strong performance. “Even if temporary, they can be crucial backups during power outages or for fire mitigation in the event of a fire,” he explained. “The Davey Remote Start FireFighter, for example, can accommodate run signals and timer programs,

increasing versatility and reducing manual interaction.”

Electric pumps, Gregan added, can be adapted to run automatically and integrated into many control systems, making them a ‘set and forget’ option.

Gregan emphasised that offering more power options provides the flexibility to select the best pump for each job, with sizes tailored to the application. He also pointed out that pump monitoring and control systems can be integrated into electric pumps for enhanced functionality.

NEW DIGS FOR IRRIGATION AUSTRALIA

We’ve moved our head office to 1/35 Paringa Road, Murrarie 4172 – pop in and say hi some time! If you’re using Google maps, just go past the point it takes you to on the map and take the first turn right to get to the entrance.

The change was prompted by a big rent hike – it’s given us the opportunity to look at accommodation with a warehouse, which should save us a lot of time with freight and logistics in the long run. We will also have a nice space for our hands-on training. Keep an eye out for announcements very soon, as we re-launch our training delivery on the back of new facilities and some fantastic new learner and student management software.

Our profuse thanks again to Davey for helping us out with warehousing for the last couple of years.

HOW NEW IRRIGATION AUSTRALIA MEMBER DIXON HELPED SOLVE A MAJOR IRRIGATION FAILURE

When a large melon farm in Chinchilla, QLD, faced a costly irrigation failure, they needed a reliable solution fast.

A layflat hose on their sub-main stretched and twisted under pressure, shifting underground lines out of place. The system had to be dug up and re-positioned –costing time and money. The farm turned to a Dixon distributor for help.

A Dixon territory manager assessed the issue and recommended Sunny Layflat – a reinforced layflat hose designed for stability and resistance to twisting. Unlike the previous hose, which failed as soon as the pumps were turned on, Dixon said that Sunny Layflat maintained its shape and position, preventing costly reinstallations and ensuring consistent water flow.

With six distribution centres across Australia, Dixon supports irrigation professionals with durable products that stand up to tough conditions said Adam Burdon of Dixon Australia. “Our goal is to provide reliable solutions that improve efficiency and reduce downtime for irrigation professionals. Irrigation Australia membership will allow us to engage with industry leaders, share expertise, and continuously improve our product offerings to meet evolving irrigation demands,” he said.

BESPOKE IRRIGATION AUSTRALIA COURSE SUPPORTS REMOTE WA COMMUNITY

The Waalitj Foundation recently engaged Irrigation Australia to deliver on-site training in irrigation efficiency in Leonora, Western Australia.

Designing the course for participants

To accommodate different levels of skills and knowledge within the group, Irrigation Australia worked collaboratively with Waalitj Foundation to customise an intensive workshop “An Introduction to Irrigation System Efficiency”.

Over the course of three full days, most of the training was spent in the workshop practicing techniques and pulling components apart. Each day had a different session aim, providing different but complementary outcomes.

Participants applied newfound knowledge to design a pressurised irrigation

system which they built, installed and commissioned. They learned to troubleshoot issues, operate systems, measure irrigation performance, work as a team and to perform tasks safely.

Calvin Ashwin, senior activity supervisor for Waalitj Foundation said that designing the course for those attending, and providing hands-on activities made the course the success it was. Calvin was particularly impressed with the trainer’s people skills, saying that Stuart Alexander (Irrigation Australia) made the course fun and that he communicated well with the group.

Skills and knowledge obtained from the workshop were linked to outcomes supporting better employment options and will be applied to a hydroponic system that grows tomatoes, cucumbers and bok choy for Leonora’s community.

Highlights

> Seventy-five per cent of participants elected to undertake additional training.

> One hundred per cent of those who attended on day one, attended day two and three. “Attendance can be an issue in remote communities, so this is a solid achievement,” said Irrigation Australia trainer, Stuart Alexander.

Tips from Waalitj Foundation

For others who may be interested in organising similar training, Calvin said that planning was key to getting good outcomes. He suggests allowing at least one month of preparation – to get a group of committed participants together, to allow time to understand the group’s abilities and skills, and to design a course around them.

PATHWAYS TO QUALIFICATIONS:

MICRO-CREDENTIALS AND CUSTOMISED TRAINING

BY STUART ALEXANDER, IRRIGATION AUSTRALIA

In the irrigation industry, a one-sizefits-all approach to training doesn’t always meet the diverse needs of our communities and workers. Irrigation Australia can deliver customised workshops to meet the needs of your organisation.

Our recent course for the Waalitj Foundation in Leonora, Western Australia, is a great example of how we can adapt training to meet community and individual needs.

Tailored training can offer clear benefits:

• It can include micro-credentials and pave clear pathways to further qualifications.

• Collaboration with local stakeholders, community, and industry representatives ensures content is relevant and culturally appropriate.

• It boosts learner confidence, increases participation and helps develop skilled, job-ready irrigation professionals.

WORKSHOPS

Flexible training solutions

Not everyone learns best in a traditional classroom setting with a trainer, a TV, and a workbook full of questions.

Customised workshops take a different approach. They are flexible, fitting around individual schedules, employment, and seasonal work demands – this is important in our industry. They also cater to various learning styles, making it easier for everyone to build skills, no matter their experience or education level. These workshops will focus on hands-on learning, with knowledge gained naturally through workplace discussions.

Customised workshops take a different approach. They are flexible, fitting around individual schedules, employment, and seasonal work demands – this is important in our industry.

Integrating micro-credentials

Customised training can incorporate micro-credentials – targeted, short training sessions that rapidly build specific skills.

Some examples are:

• Basic Concepts of Irrigation Pumping Systems

• Irrigation Efficiency and Practical Skills Irrigation and the Environment

• refresher sessions in Electrofusion and Butt Welding.

Micro-credentials often award digital badges, which complement traditional certifications and give participants tangible proof of their competencies. These verifiable digital credentials enhance employment opportunities, allowing jobseekers to highlight their practical skills online to potential employers.



Relevant, hands-on skills

Customised workshops and microcredential courses deliver immediate, hands-on experience that is directly relevant to industry needs. Participants can improve their employability, job satisfaction and career development.

Clear pathways to certification

A major advantage of customised workshops is their integration with recognised qualification frameworks. Participants gain practical skills and clearly defined pathways to certifications such as the Certificate III in Irrigation Technology. This structured progression motivates learners, supports career development, and encourages continuous professional advancement.

Positive community feedback

Community feedback shows just how valuable these customised workshops are. Participants appreciate having access to quality training that suits local needs, even in remote areas. They gain confidence, better employment prospects and stronger engagement in learning. Prospective employers also benefit, as they can hire candidates who have local training, are keen to learn new skills, and are working towards qualifications in the irrigation sector.

A model for sustainable workforce development

The Leonora approach, developed and delivered by Irrigation Training Australia RTO #91313, provides a model that can be used elsewhere. Training – whether accredited or not – can be designed around community and individual needs. In 2025 we aim to expand our range of microcredentials and digital badges.

Customised training workshops help build a strong, skilled workforce. Investing in training and micro-credentials isn’t just useful – it’s essential for the future of our industry. As the sector evolves, this training approach will continue to play a key role in preparing professionals for the opportunities and challenges ahead. Every career path needs to start somewhere.

The leaves don’t always drop as expected: Navigating mental health in autumn

As seasons shift and the long days of summer give way to the cooler air of autumn, many in the irrigation and agricultural industries feel the change not just in the environment but also in their mental well-being. Seasonal change can have profound effects on mood, enthusiasm and motivation. Autumn in particular, can present unique challenges as workloads adjust and daylight hours lessen.

The impact of seasonal change on mental health

Research shows that seasonal transitions can affect mental health. Seasonal Affective Disorder (SAD) is a form of depression that follows the seasons and can be made worse by reduced daylight and changing routines (Melrose, 2015). While SAD is commonly associated with winter, autumn can also bring feelings of fatigue, low energy, and anxiety about the months ahead.

For workers in the irrigation sector – many of whom operate in remote rural areas –these seasonal shifts can be compounded by the physical demands of the job, isolation, and unpredictable workloads.

The increase in seasonal demand in certain regions adds pressure, sometimes leading to burnout and fatigue (Safe Work Australia, 2023). Acknowledging these mental health challenges is the first step in addressing them.

A rural perspective: Mental health in the agricultural and irrigation sectors

Unlike urban workplaces, regional areas often lack direct access to mental health resources, making it essential to encourage conversations and support networks within the community. Organisations like TIACS (This Is A Conversation Starter) bridge the gap by providing free, professional mental health support to workers in trade and rural industries. TIACS’ model ensures that those in isolated regions can access the help they need without financial barriers, offering support via phone and text services.

Workplace Health and Safety (WHS) regulations and mental health

Australian Workplace Health and Safety (WHS) laws state that employers have a duty of care to provide a safe and

healthy workplace, including addressing psychological risks (Work Health and Safety Act, 2011). Safe Work Australia identifies work-related psychological hazards, such as excessive workload, isolation, and poor organisational culture, as key risk factors for mental health issues. Employers are encouraged to implement controls such as:

• Regular mental health training and awareness programs.

• Flexible work arrangements where possible, to support work-life balance.

• Encouraging open communication and a positive workplace culture.

• Ensuring workers have access to Employee Assistance Programs (EAPs) and mental health resources.

Autumn is a prime time to reinforce the message that mental health is just as critical as physical safety. Encourage open conversations among teams, check in on colleagues, and take proactive steps to manage stress.

Toolbox talks are a great way to start a conversation around mental health and to get on top of SAD before it really takes off.

 BY STUART ALEXANDER

PRACTICAL STRATEGIES FOR MANAGING MENTAL HEALTH IN AUTUMN

1. Prioritise daylight exposure – With shorter days, maximising natural light is crucial. Natural light helps regulate mood and sleep patterns and can help take the gloom out of the day.

2. Stay connected – Social isolation is a risk factor for declining mental health. Encourage connection through community groups, sporting clubs, industry networks, or a simple chat with a co-worker.

3. Seek professional support – Services like TIACS provide free access to mental health professionals who understand the unique pressures of working in rural settings and remote workplaces.

4. Monitor workload and fatigue – To prevent more severe mental health issues, recognise the signs of burnout and take proactive steps to rest and recover.

5. Normalise the conversation – Employers and industry leaders can encourage open discussions around mental health, reducing the stigma that is too often attached to the conversation. Promote a culture where workers feel safe to seek help.

As autumn sets in… It’s important to remember that just like in nature, change isn’t always predictable. The leaves may not drop exactly when expected, or where we may expect them to – almost certainly they won’t drop in the mulch heap. The same goes for our mental health, we need to ‘rake up and deal with those bits that fall outside the comfort zone’. By recognising the impact of seasonal shifts and taking positive steps to support mental well-being both individuals and the entire industry will benefit.

Social isolation is a risk factor for declining mental

health. Encourage connection through community groups, sporting clubs, industry networks, or a simple chat with a coworker.

A pile of leaf litter, when controlled and well maintained, provides nutrient and influences soil and crop health. Control and manage your mental leaf litter and see how it benefits you. Particularly in those autumn months when your Leaves Don’t Always Drop as Expected.

If you or someone you know is struggling, TIACS is an invaluable resource. Their free, confidential support service is available to anyone in the trade and rural sectors, including the Irrigation Industry. Some of us can recall the inspiring address at last year’s conference in Sydney by Jason Banks. Call or text 0488 846 988 to start the conversation.

Surveying water storage for future metering.

NSW has introduced a metering system for floodplain harvesting in the northern Murray–Darling Basin, with about 80 per cent of the total volume of licences issued.

Floodplain harvesting, previously unmeasured, is now tracked to improve transparency and sustainability.

Water is metered using storage-level measurement (radar sensors or pressure transducers) or point-ofintake meters, with data sent via telemetry.

Implementation challenges include a shortage of qualified professionals for meter installation and telemetry coverage gaps in remote areas.

While compliance obligations have increased, Dan Connor, Director of Metering and Licensing at the NSW Department of Climate Change, Energy, Environment and Water, says that reliable measurement is expected to build public trust and improve on-farm water management.

Ongoing system improvements and collaboration between government and industry are needed for effective implementation.

After years of debate and policy development, New South Wales has introduced a metering system for floodplain harvesting to improve accuracy and transparency of water taken in the northern Murray–Darling Basin. With around 80 per cent of intended licences now issued, floodplain harvesting – which was previously unmeasured – is now being tracked for the first time.

South Wales – how metering is changing water management

Floodplain harvesting has been a controversial issue, with concerns about fairness, transparency and sustainability. But with the new metering rules in place, irrigators in northern NSW must now measure and report the water they collect from floodplains.

According to Dan Connor, Director of Metering and Licensing at the NSW Department of Climate Change, Energy, Environment and Water (DCCEEW), this shift marks a major change in how floodplain harvesting is managed. "Floodplain harvesting metering wasn’t possible without a licensing framework in place," Connor explains. "With the licensing framework now in place, we can require metering for floodplain harvesting. This is a significant step forward in water management in NSW.”

The new system ensures that water harvested during floods or heavy rainfall –typically stored for later irrigation use – is recorded and monitored within a regulatory framework.

How is floodplain water being metered?

There are two main ways to meter floodplain harvesting, depending on how water moves through each property.

1. Storage-level measurement (about 85 per cent of users). Most irrigators are metering their floodplain water based on changes in on-farm storage levels. Two types of technology are used:

• Radar sensors – measure water levels by detecting the distance between the sensor and the water surface – from the top down. This technology is widely used in mining and petroleum industries and is used in agriculture in on-farm management systems but is new to floodplain water measurement

Pressure transducers – submersible devices that release gas pulses and measure pressure differences between the sensor and the water surface – from the bottom up. This method has been used in river gauging worldwide but is being applied to floodplain harvesting for the first time.

Both technologies send data via telemetry to the department and to the regulator, allowing for real-time monitoring and compliance.

To ensure accuracy, all water-level measurements in these on-farm storages must be converted to a volume. "One of the key requirements is that these on-farm

storages be professionally surveyed to establish an accurate relationship between water level and storage volume and to align all level measurements to the Australian Height Datum (AHD)," Connor explains

2. Point-of-intake meters. For some properties, it is easier to measure water at the point where it enters the farm. These ingress meters work like traditional nonurban water meters, are pattern approved by the National Measurement Institute and are installed in compliance with AS4747 standards at water entry points.

Challenges in implementing the new system

Transitioning to metered floodplain harvesting has come with challenges. The diversity of properties means there is no simple, one-size-fits-all approach, and irrigators have had to adjust to new compliance requirements.

One major challenge has been a shortage of certified professionals to install and verify meters and to survey storages – referred to as Duly Qualified Persons (DQPs). "There’s been a shortage of both meter installers and surveyors," Connor says. "The demand for surveyors, especially with competing infrastructure projects, has slowed progress. But we’re working with industry to address these bottlenecks, including subsidising training courses."

Another challenge has been telemetry coverage in remote areas, which is essential for automatic data reporting. While most properties transmit data in real time, a "black spot" exemption allows for manual reporting where necessary. The department is reviewing telemetry requirements to improve system reliability, usability and utility.

Industry perspectives and concerns

While the floodplain harvesting licensing is a significant step forward in water management, industry representatives have raised concerns about the implementation of the framework. The NSW Irrigators’ Council (NSWIC) supports the need for floodplain harvesting measurement but is

concerned about its complexity, arguing that it is too prescriptive. There have been several regulatory changes to address some of these problems, but the pathway to compliance remains challenging.

“Despite efforts to comply, many water users face barriers beyond their control, including issues with accuracies of works approvals, delays in meter installation and a lack of duly qualified professionals to complete the required work,” an NSWIC spokesperson said.

The Council also notes that water users need greater access to their own metering data in real time, rather than relying on daily reporting, to better manage their water use. Additionally, they have raised concerns about the financial burden of compliance and the economic impact of reduced floodplain harvesting allocations.

What this means for irrigators

Connor says that for irrigators, the shift to metering means new compliance obligations but also potential benefits. Reliable, tamper-evident measurement helps to build public trust in the industry, providing transparency and addressing concerns about water use.

Some irrigators also see opportunities to use metering data beyond compliance, integrating it into on-farm systems for better water management.

What’s next?

While the licensing and metering system is well underway, there is still work to be done. Connor says ongoing improvements will be needed to keep the system practical and effective.

"The job is never done, there is always room for improvement," he says. "We need to continually review our processes, improve technology, and work with industry to ensure effective implementation."

BECOME A CERTIFIED DQP

Irrigation Australia continues to offer training and certification programs for DQPs. We have made major improvements to course content in the last few months and are developing more flexible delivery options.

We are in regular discussions with the department to ensure changes to policy are communicated effectively and look forward to working with all stakeholders including DCCEEW to help ensure a practical approach to the rollout of new floodplain requirements.

The newly redeveloped sports oval at MacPherson Park Recreation Reserve, irrigated using a VSDcontrolled pump system for improved efficiency and reliability.

Smart pumping system cuts costs for MacPherson Park Recreation Reserve

MacPherson Park Recreation Reserve in Melton, Victoria, recently upgraded its irrigation system to improve efficiency and reduce costs.

The project included Australia’s first installation of the Hydrovar X variable speed drive.

The system uses two Lowara e-SV 10SVX06 pumps with variable speed technology, reducing energy use and equipment size.

Smart controls, including Bluetooth connectivity, allow real-time monitoring and adjustments.

A rain sensor prevents unnecessary irrigation, and a brick pump house enhances security.

The new system operates more quietly and efficiently than previous setups, with positive early feedback from users.

Managing energy and water use efficiently is critical in large irrigation projects, where operating costs and sustainability go hand in hand. Variable speed drives (VSDs) offer a cost-effective solution by adjusting motor speed to match demand, reducing energy consumption, lowering running costs, and extending equipment lifespan. MacPherson Park Recreation Reserve in Melton, Victoria, recently put this technology to work as part of a major redevelopment. With a newly developed sports oval and a growing number of users, the reserve needed an upgraded irrigation system that could balance performance, reliability, and cost efficiency.

To achieve this, the principal consultant, local council, and Brown Brothers Engineers Australia collaborated to install Australia’s first Hydrovar X

VSDs. These advanced drives allowed for a smaller pump and motor size, reducing both upfront investment and ongoing operational expenses − without compromising irrigation performance.

Smarter design for greater efficiency

David Gardiner from ULS Group led the installation of the pumps and supporting infrastructure, working with Brown Brothers Engineers’ Business Development Manager Michael Garas on system specifications.

The irrigation system was designed to deliver 6.32 L/sec at 650 kPa, ensuring the optimal balance between performance and energy efficiency.

To achieve this, two Lowara e-SV 10SVX06 pumps, each fitted with a Hydrovar X VSD, were installed in parallel. This configuration allowed the pumps to share the workload, improving efficiency while

 ARTICLE PROVIDED BY BROWN BROTHERS ENGINEERS AUSTRALIA

ensuring increased redundancy due to the wider performance envelopes of each pump.

The VSDs played a key role in reducing system size and costs. They adjust pump output to meet demand, ensuring efficient energy use while maintaining the required pressure for irrigation.

“The original design specified dual 10-stage pumps with 4.0 kW motors,” Michael explained. “By incorporating Hydrovar X, we were able to downsize to 6-stage pumps with 3.0 kW motors. This reduced both upfront supply costs and long-term energy consumption.”

Reliability and smart controls

The system includes additional features to improve reliability and simplify maintenance. An INCA surge protection panel was installed to safeguard electrical components, and the pumps draw water from a rain-fed tank equipped with a rainwater sensor. The sensor ensures that irrigation only occurs when necessary, automatically shutting off the system in periods of excessive rainfall.

The project also included practical design choices to improve durability and security. The pumps were housed in a brick shed rather than a tin enclosure to better protect them against theft. Valve banks were installed off-field, under bench seating, making them more accessible for maintenance while remaining out of sight for aesthetic reasons.

WHEN ARE VARIABLE SPEED DRIVES USEFUL?

Variable speed drives (VSDs) are particularly useful in applications where:

Caption: The pumps draw water from a rain-fed tank equipped with a sensor (left). Valve banks were installed off-field, under bench seating, making them accessible for maintenance while remaining out of sight.

• water demand fluctuates significantly, such as irrigation systems that operate under varying load conditions

Advanced control features and connectivity

The Hydrovar X offers user-friendly controls that simplify operation. Irrigation managers can make real-time adjustments using Bluetooth connectivity, ensuring efficient performance without needing to be physically at the pump shed.

Benefits of the new system

With the system now fully operational and the turf laid in late 2024, early feedback has been positive, with the client appreciating the ability to monitor and adjust the pump remotely. Key benefits of the upgraded irrigation system include:

• Energy efficiency – Variable speed drives optimise energy use, reducing operational costs.

• Lower maintenance – “With fewer moving parts and a smaller system, we introduce fewer potential failure modes,” Michael noted. “That means less downtime and lower ongoing maintenance costs.”

Two Lowara e-SV 10SVX06 pumps, each fitted with a Hydrovar X VSD, were installed in parallel. This configuration allowed the pumps to share the workload, improving efficiency while ensuring increased redundancy due to the wider performance envelopes of each pump.

• energy savings are a priority, as VSDs adjust pump output to match demand, reducing unnecessary power consumption

• equipment lifespan is a concern, as VSDs help reduce wear and tear by minimising abrupt starts and stops

• noise levels need to be controlled, as VSD-driven pumps typically operate more quietly than fixedspeed alternatives.

A built-in Setup Genie streamlined the initial configuration, while Bluetooth connectivity enabled technicians to monitor and adjust settings via a smartphone app. According to Michael, one of the biggest advantages of this system is that technicians can step away from the pump shed and fine-tune the system in real time while observing rotor performance on the oval.

However, VSDs may not be necessary or cost-effective in cases where:

• the system operates at a consistent load, with little to no variation in demand

• the additional upfront cost of a VSD does not justify the expected energy savings over time

• simpler, on/off pump control is sufficient for meeting operational needs.

Another key function, the advanced pipefill mode, gradually fills pipes at a lower speed, preventing pressure fluctuations that could trigger nuisance tripping or damage pump components. Once fully pressurised, the controller transitions smoothly to full operating speed.

• Quiet operation – “Compared with the park’s other ovals, this system is noticeably quieter,” David said. “We’ve installed many Lowara pumps, but these ramp up more quietly and operate smoother, making a real difference in day-to-day operation.”

• Improved sustainability – Smaller, lighter pumps reduce material use and energy consumption, lowering the system’s overall carbon footprint.

• Remote monitoring and control – The system allows real-time adjustments via Bluetooth, improving usability and efficiency.

With variable speed technology and smart controls, the project team created an efficient, cost-effective, and sustainable irrigation system for MacPherson Park Recreation Reserve.

The pumps draw water from a rain-fed tank equipped with a sensor (left). Valve banks were installed off-field, under bench seating, making them accessible for maintenance while remaining out of sight.

Research: Predicting future water needs in Riverland vineyards

A case study on how climate change affects vineyard irrigation in the Riverland is helping a Basin-wide project guide other growers in making informed water decisions.

Researchers from the South Australian Research and Development Institute (SARDI) used climate, soil and crop data to project future changes in rainfall, temperature and evapotranspiration (loss of water from plants, soil and other surfaces due to evaporation and transpiration) – key factors affecting irrigation demand.

Findings showed a 27 per cent decline in seasonal rainfall and an 8.2 per cent increase in evapotranspiration by 2099. As a result, irrigation needs in the

Loxton region are expected to rise by 4.2 per cent by 2039 and up to 17 per cent by the end of the century, driven mainly by reduced rainfall.

The study validates the One Basin CRCbacked project, ‘Predicting the impact of climate change on irrigation demand across the One Basin’, a Charles Sturt University and SARDI collaboration, which will model future irrigation needs for almond, wine grape, cotton, and rice growers (incorporating grower insights). Future phases aim to develop geospatial irrigation demand maps, improving water resource planning.

EMERGING LEADER: AN INTERVIEW WITH STEPHEN JENNINGS INTERVIEW

BY EVE WHITE, IRRIGATION AUSTRALIA

While many in the irrigation industry have deep technical expertise, fewer combine it with strong leadership and a commitment to mentoring others. Stephen Jennings is one of those rare individuals, and his dedication was recently recognised with an Irrigation Australia award. We caught up with the Franklin Electric national sales manager to discuss his career journey, the industry's biggest challenges, and the future of pumping technology.

Stephen Jennings has built his career on innovation, efficiency, and a commitment to mentoring others. His dedication to improving pumping operations and sharing industry knowledge earned him the Emerging Leader Award at the Irrigation Australia Conference last September. Now, as national sales manager at Franklin Electric, he is focused on driving sustainability and adopting new technologies to strengthen the industry’s future.

“I’ve always believed that passing on knowledge is the only way our industry will continue to grow,” he says. “If we don’t teach the next generation, we lose valuable skills.”

A career built on learning and leadership

Stephen began his career as a fitter machinist at Brown Brothers Engineers Australia, where he developed expertise in pump assembly, servicing, and troubleshooting. He credits early mentors Stephen Johnstone and Leo Spoor for shaping his technical foundation and leadership skills, eventually leading him to a workshop management role.

“That early experience gave me a real appreciation for problem-solving,” he says. “It taught me that every system has its inefficiencies, and it’s up to us to identify and fix them.”

His career later took him into drainage, sewer systems, and control system manufacturing, expanding his knowledge of pump controls and circuitry. This technical expertise opened the door to Franklin Electric, where he started as a technical service manager before transitioning into sales and leadership.

Encouraged by mentor Malcolm Eyre, Stephen moved back to Brown Brothers to develop his sales skills before returning to Franklin Electric – this time in a senior leadership role. Now, under the guidance of managing director Vic Tannin, he continues to refine his approach to strategic growth and problem-solving.

Stephen’s leadership is rooted in his belief that the industry’s future depends on empowering the next generation. “I’ve been lucky to learn from great leaders along the way,” he says. “Now, my goal is to pass that knowledge on and help others grow into their potential.”

Challenging the status quo in pumping efficiency

Stephen believes that real efficiency gains in pumping don’t just come from incremental improvements in pump design but from rethinking system design and embracing smarter motor technologies.

“Pumps haven’t changed dramatically in efficiency – it’s physics. But where we see major gains is in system design and energy management.”

The biggest shift in recent years has been the adoption of variable frequency drives (VFDs) and permanent magnet motors, which significantly reduce energy consumption. However, traditional installation practices and upfront costs continue to slow widespread adoption.

“It’s an education challenge. Many still rely on old techniques, but when we can demonstrate real power savings and payback periods, we start to shift mindsets.”

Another key challenge is irrigation system design, particularly mainline sizing, where undersized systems lead to higher friction losses and increased energy costs.

“Irrigation design has come a long way, but we still see systems that aren’t optimised. The good news is that awareness is growing, and we’re seeing more emphasis on education and best practices,” Stephen noted.

The future of pumping: AI and smarter energy use

Looking ahead, Stephen sees AI-driven pump control as the next major leap in efficiency and energy management.

“Right now, pump control is reactive. AI could change that – allowing systems to make smarter decisions in real time based on demand, energy availability, and cost.”



Future systems could automate efficiency improvements, dynamically optimise energy sources (solar, grid, or diesel), and adapt to real-world conditions.

“We’re already seeing interest in hybrid power sources for pumping – AI could take that a step further by selecting the most cost-effective and sustainable option in real time.”

He also believes tighter energy regulations are needed to raise the standard for pump motors.

“We have pretty loose laws around emissions for stationary engines and minimum energy performance standards (MEPS) for electric motors. Strengthening those would stop inefficient products from entering the market and driving down efficiency standards.”

A vision for growth and industry leadership

At Franklin Electric, Stephen is committed to making the company an indispensable partner to its customers by focusing on quality, availability, service, innovation, and cost.

“We’ve built a strong reputation, but we’re not done yet. There’s still so much potential for improving service, availability, and training – not just within our company, but across the whole industry.”

Investing in training, strategic goal setting, and education is key to long-term success.

“We need to invest in people. The more I can empower those around me, the more challenges I can take on.”

Advice for young professionals

For those starting in irrigation and water management, Stephen’s advice is simple:

“Stick at it, push boundaries, and never accept ‘that’s just how we do it.’ Understand every aspect of what you do, and success will follow.”

With water management and energy efficiency more critical than ever, there has never been a better time for young professionals to challenge traditional thinking and drive meaningful change in the industry.

STATE ROUNDUP

BACKING AUSSIE FARMERS WITH AN ADDITIONAL $20 MILLION FOR AG-TECH CONNECTIVITY

The Australian Government is investing an extra $20 million in the On Farm Connectivity Program (OFCP) to support Australian farmers with cost-of-living relief and improved productivity. This brings the total investment in the program to $53 million, enabling over $100 million in agtech purchases nationwide.

The program is based on the 2021 Regional Telecommunications Review, which found that poor connectivity was limiting the adoption of modern farming technologies.

Previous rounds of OFCP provided rebates of up to 50 per cent – worth up to $30,000 – for eligible equipment and technology. Thousands of farmers have benefited, using ag-tech to monitor activity in real time, improve safety, and enhance productivity.

Following the success of earlier rounds, the government expanded Round 2 funding to $18 million in 2024. Round 3 will open in 2025, with grants distributed in 2025-26. The Department of Infrastructure, Transport, Regional Development, Communications and the Arts says that it will review guidelines to ensure the program continues to meet farmers’ needs.

AUSTRALIA’S WATER CRISIS: COUNCILS STRUGGLING TO KEEP UP

Imagine running a town without a clear water management plan – no strategy for capturing rain, cooling streets or preparing for drought. That’s the reality for many councils across Australia, according to a new report highlighting major gaps in local water planning.

The Water Sensitive and Liveable Communities report, conducted by researchers from Monash University, Curtin University, and CSIRO, surveyed 102 councils to understand their biggest water challenges. The findings? Many councils lack the tools, knowledge, and policies needed to ensure long-term water security and liveability –leaving them vulnerable as climate change intensifies droughts and extreme weather.

A patchwork approach to water management

More than 90 per cent of local government areas can access safe stormwater and wastewater management services.

However, while most councils manage stormwater independently, many rely on external organisations for drinking water, recycled water, and wastewater services. In New South Wales and Queensland, more than 80 per cent of councils manage all water services themselves.

Many councils also lack in-house expertise, depending on external consultants for planning. Remote councils are particularly reliant on outside help.

A lack of long-term planning

Despite growing climate risks, more than 60 per cent of councils surveyed do not have an integrated water management plan. This means stormwater harvesting, water recycling, and conservation efforts are often overlooked.

Rainwater collection is also inconsistent. South Australia has a high uptake of rainwater tanks due to past water shortages, but many remote areas still lack access to treated tank water.

Heatwaves and urban greening –a low priority

With heatwaves becoming more frequent, urban greening and cooling strategies are vital. Yet only 20 per cent of rural councils have an urban greening policy. Many assume existing bushland provides enough cooling, rather than actively implementing strategies like tree planting or watersensitive urban design.

What needs to change?

The report identified key priorities for improving water management in regional and remote areas, including:

Councils out of the loop on new research

Most councils are unfamiliar with the latest Australian Government–funded research on water-sensitive cities and heat mitigation. More than 75 per cent of remote councils and 55 per cent of regional councils reported little to no knowledge of these resources.

60% OF COUNCILS LACK AN INTEGRATED WATER MANAGEMENT PLAN

50% OF REMOTE

COUNCILS HAVE NO WASTEWATER RECYCLING PROGRAMS

ONLY 20% OF RURAL COUNCILS HAVE AN URBAN GREENING POLICY

• developing water management tools tailored to local needs adapting existing research for regional and remote applications

• creating a national platform to share best practices investing in infrastructure upgrades and sustainable water reuse

• integrating First Nations cultural water knowledge into planning.

The way forward

Australia’s water future depends on action at all levels – local, state, and national. Many existing water management tools don’t suit regional and remote areas, so customised solutions, better funding, and stronger collaboration are needed.

Without better planning, councils risk falling further behind. The report highlights the importance of turning knowledge into action before the next drought or heatwave puts even more pressure on already struggling communities.

What business owners need to know about Australia’s gender equality strategy

The Australian Government’s Working for Women: A Strategy for Gender Equality, is a 10-year plan aimed at improving women’s economic security, leadership, and workplace participation. Key measures businesses should be aware of are:

Superannuation on Paid Parental Leave (PPL) – From 1 July 2025, the Government will pay super on PPL, which could influence workplace policies on parental leave and employee benefits.

New supplier registration for women-led businesses – A voluntary registration process in AusTender will allow the

Government to track and analyse contracts awarded to women-owned and led businesses.

Regular reporting and gender analysis –Government strategies will include gender analysis, and businesses engaging with government contracts may see increased reporting requirements.

Stronger gender representation targets –Government boards and advisory bodies will have expanded targets for women’s representation, including at the portfolio level and in Chair and Co-chair roles.
