Irrigation Australia Journal Winter 2025

From the Chair&CEO

Irrigation Australia has a proud history in supporting Australia’s irrigation industry – and continues to empower the industry through knowledge, innovation and sustainable best practice. We know that many members are struggling through skills shortages, weather extremes and other business challenges, and the Association has shared some of that pain this financial year.

In this edition of the Journal, we spotlight careers and training. You’ll also find stories on solar pumping, digital technology, and the potential of soil carbon farming.

Training

25/26 is looking bright, with a lot of interest in private courses, a well-structured calendar, and training rolling out through Ammonite (our new learning management platform). Concurrent and flexible delivery options are working well and the feedback we’re getting from some of the new programs (including the Queensland Governmentfunded Irrigation Efficiency and Practical Skills micro-credential) is spectacular.

Irrigation Australia is also supporting the Food, Fibre and Timber Industries Training Council (FFTITC) to establish a trade apprenticeship for irrigation technicians – addressing critical skills shortages across Western Australia. Elevating the Certificate III in Irrigation Technology from a traineeship to a trade apprenticeship could raise industry standards, improve regional career pathways, and support a more sustainable future. Whether you're in the field, employ technicians, or simply care about responsible water use, your input counts. Respond to FFTITC’s survey here, before it closes on Friday, 25 July 2025.

Marking a new era of locally driven certification, the Australian-led Certified Irrigation Designer

Program is set to launch, delivering tailored exams, enhanced resources, and a streamlined assessment process. Further, we’re building on the success of a careers presentation in Queensland schools by exploring similar partnerships with other education departments.

Following the successful launch of the self-paced Introduction to Irrigation – Part A, two new courses – Part B: Landscape and Part B: Agricultural – build on Part A’s solid foundation to explore irrigation practices in greater depth. We thank Sam O’Brien for developing the content, and our team for all the hard work in the back end to ensure a positive student experience. We also acknowledge Sam’s significant contribution to the Association and wish him well in his future career.

Additionally, we’d like to highlight a couple of fantastic member opportunities – our new self-paced online training subscription, and the upcoming Waterwise Expo in August.

The training subscription provides great value for member companies. For a one-off annual fee there is no limit to the number of staff employers can have complete the courses. These are great “taster” activities to explore further professional development in the industry, with around 15 hours of content overall. Heavily discounted for members, the subscription can be accessed here. Around 150 students have already been enrolled using the member subscription.

Lastly, it’s nearly Waterwise Expo time in Perth!

Rebecca New has done an incredible job securing exhibitors and organising the venue and program –ably supported by our excellent WA committees.

The Expo has a unique format, allowing delegates to circulate through different demonstrations

and displays. Highlights include an innovation showcase, mental health talk, the exhibition, tours of the Vines Golf Course irrigation installations, a waterwise panel with Irrigation Australia, the Department of Water and Environmental Regulation, and Water Corporation – and of course fantastic networking with fun golf-themed activities provided. We look forward to catching up with you on 13 August.

Please review all our training offerings here While there, take a look at our wonderful new Talent Hub and get involved. The industry’s future depends on attracting, training and keeping new people; and your association is the ideal resource to support that.

TRAINING: A guide for employers

Irrigation Australia’s purpose is to serve as a centre of excellence, driving the adoption of efficient irrigation practices across

Building a skilled workforce

The Certificate III in Irrigation Technology remains the industry’s core qualification, equipping workers with critical skills in system installation, maintenance, and water management. This qualification has long served as a key entry point for industry training, although we’ve recently focused on a number of shorter, entry level and intermediate courses for new starters.

We’re lucky to be able to deliver training under a nationally recognised, portable training system but the funding offered by state and territory governments to support our essential skills differs significantly. At a high level, Irrigation Australia’s national training and advocacy strategy calls for:

• More consistency across state and territories – the financial burden on our Association with compliance and separate funding systems is significant.

• Fit for purpose funding - for example criteria which ensure that new employees are able to be brought on and tested before a business makes a major investment in training.

• More financial support for shorter duration courses which contribute to the core qualification – leading to stronger completion rates and a better return on government investment.

• Flexible funding options for special requirements / new or innovative training options which do not easily fit the Australian Quality Framework – it takes a lot of time to get a new qualification registered.

Currently Irrigation Australia does not have funding arrangements for NT, ACT, or Vic. Victoria has been a target for a long time but there is no appetite to support the industry.

WA has the most generous funding arrangements, but we struggle to meet requirements to get support for existing workers. Queensland provides least financial support for the Cert III qualification, but has innovative programs in the flexible options category, including micro-credentials funding.

Investing in workforce capabilities: Steps for employers

Identify funding sources – Find the latest information on available grants and subsidies here, on the Irrigation Australia website. Consider joining Irrigation Australia to support its advocacy efforts, especially if you are in a region which is not well-supported. Consider regional committee roles – all active committees have project ideas in play to help address skilling challenges in their regions.

Plan for workforce development – Investing in skilled employees strengthens operational success and staff retention.

SOLAR IRRIGATION’S

RISE: technology, policy and industry insights

Solar irrigation is gaining traction as a cost-effective and sustainable alternative to diesel and electric pumps.

Technology choices depend on duty point, water source depth, and piping efficiency, influencing both performance and cost savings.

Hybrid systems and energy storage help ensure consistent operation, reducing dependence on diesel backup.

Advanced software and AI-driven solutions are shaping the future of solar irrigation efficiency.

Government incentives focus on power generation rather than off-grid solar irrigation, creating policy gaps.

Environmental benefits include lower emissions and improved water efficiency, but product lifecycle impacts should be considered.

Collaboration across industries is essential to overcoming regulatory and installation challenges.

Economic viability depends on ROI analysis, factoring in upfront costs versus long-term savings.

SNAPSHOT

 INTERVIEW WITH STEPHEN JENNINGS

THERE’S NO QUESTION THAT SOLAR IRRIGATION IS GAINING TRACTION AS IRRIGATORS SEEK DEPENDABLE, COST-EFFECTIVE, AND ENVIRONMENTALLY SUSTAINABLE ALTERNATIVES TO DIESEL OR ELECTRIC PUMPS. WE INTERVIEWED STEPHEN JENNINGS OF FRANKLIN ELECTRIC FOR HIS INSIGHTS AS A PUMP SUPPLIER FAMILIAR WITH SOLAR IRRIGATION PROJECTS.

Selecting the right solar irrigation components

Irrigation Australia: What factors influence the selection of solar panels, pumps, and other components for a specific irrigation project?

Stephen: The optimal duty point, or daily total water required to be pumped if transferring. After that, an assessment of the pumping scenario, depth of water and suction lift to the pump location, if it’s a surface pump.

Head calculations (the height a pump can raise liquid) and efficient pipe design are next: larger piping reducing pressure loss, can have a big impact on solar panel numbers needed, and savings on initial equipment costs.

“In Australia, a PV electrician must be engaged for systems of 90 v or more.”

Stephen: This is a big challenge. Batteries are starting to make some movement, but return on investment (ROI) is long, with a large initial investment. In many cases, people are using diesel generators to operate in low-light conditions or combining solar and diesel to make up the energy needed to reduce fuel costs.

Advancing efficiency with smart solar innovations

Irrigation Australia: What are the latest advancements and innovations in solar irrigation technology that are likely to shape the future of the industry?

Stephen: The blending of different sources of power from battery, grid, generator and solar PV. The biggest thing will be software/smart technology, possibly AI, to best determine how to bring these powers together and maximise efficiencies. Even following the energy market to buy and store grid power at cheap or wholesale prices. I’ve seen this work successfully on a project by others in Gippsland, Victoria.

Types of solar pumps: advantages and applications

Irrigation Australia: What are the different types of solar-powered irrigation systems currently being implemented in Australia (e.g., submersible pumps, surface pumps, drip irrigation, sprinkler systems)? What are their respective advantages and disadvantages?

Stephen: Solar pumps are available in three types:

• Submersible pumps: Submerged in water, these pumps push water to the surface. They are typically used for deeper water sources such as wells, dams and rivers where suction lift is too high to achieve.

• Surface pumps: Installed above the water level, these pumps draw water into the system or below the water source as a flooded suction.

For solar panels, an assessment of area required and ground formation to determine the array frame is important. For example: Rammed post, strip footings or a concrete slab. Large systems need a PV electrician involved to make further site assessment. In Australia, a PV electrician must be engaged for systems of 90 v or more.

Ensuring reliability: energy storage and hybrid solutions

Irrigation Australia: How is the energy storage component (e.g., batteries) integrated into solar irrigation systems to ensure reliable water supply, especially during periods of low solar irradiance or high demand?

Battery cost is also going to be a big one going forward. As battery costs come down, we will see more utilisation – more so in power generation, not solar pumps.

Installing

and maintaining solar irrigation systems

Irrigation Australia: What are the key considerations for the installation and maintenance of solar irrigation systems to ensure long-term efficiency and reliability?

Stephen: At Franklin Electric, our considerations would be the pump type and location, and access for serviceability. Another consideration is the PV array –being able to maintain grass and trees, so as not to overgrow and shade panels.

• Solar-powered direct pumps: Suitable for smaller irrigation projects, these pumps are directly powered by solar panels and do not require batteries.

Not all systems need batteries. There is minimal use of batteries currently in the industry.

Choosing the best pump for the job will depend on the depth of the water source, the necessary water flow rate, and the size of the area to be irrigated.

Planning a solar irrigation project

Irrigation Australia: What are the key feasibility considerations when planning a solar irrigation project, particularly concerning water source, energy needs, and agricultural or urban planning requirements?

“The largest challenge we find is that clients underestimate the number of solar panels required and suitable locations to position these, as well as the space they take up.”

planning and development phases of solar irrigation projects, and how can these be mitigated?

Stephen: Key considerations are: Is it a direct solar pump that is required during daylight hours, or will it be for power generation, where the pump and other items are powered from the system and have a backup power source to ensure irrigation can occur at required times. For example, if pumping is required overnight then a solar pump would not be suitable. In that case, it would be a power saving exercise via solar and battery, or other energy source. Pumping during the day would reap the biggest benefits.

Challenges and solutions in solar project development

Irrigation Australia: What are the common challenges encountered during the

Stephen: The largest challenge we find is that clients underestimate the number of solar panels required and suitable locations to position these, as well as the space they take up – especially on large projects where government certification standards need to be met for larger power generation. This is a hard one to approach and I suggest a solar installation PV Certified electrical company should also be engaged early in planning.

Assessing cost-effectiveness and return on investment

Irrigation Australia: How do you assess the economic viability and return on investment for solar irrigation compared to traditional irrigation methods?

Stephen: We look at Return on Investment (ROI): The cost difference of solar products versus a mains grid solution, estimated from running costs. This gives a difference on ROI vs installing mains grid. We never add our costs to get AC mains power to the site. If that is required, it can dramatically reduce the ROI.

Government incentives and policy gaps

Irrigation Australia: What roles do government policies and incentives play in promoting the adoption of solar irrigation technologies in Australia?

Stephen: My personal opinion – there isn’t enough incentive from governments. Most policy applies to solar power generation overall and connection back to the grid. Totally off-grid pumping isn’t really considered well in current policy.

Navigating sustainability concerns in solar projects

Irrigation Australia: Are there any potential negative environmental impacts associated with solar irrigation projects, and how can these be addressed?

Stephen: I guess the environmental impact of creating the products used and disposal of at end of life will be a concern but does not seem to be a big issue as yet. We will see further on this from generic solar supply companies, I’m sure, in the future.

The state of solar irrigation in Australia

Irrigation Australia: What are the current trends and outlook for the solar irrigation market in Australia?

Scan to see how Lowara and Hydrovar X reduced motor size and improved efficiency in this irrigation upgrade.

Stephen: This is gaining momentum. Delays could be initial costs –especially relating to batteries and if needing to irrigate outside of sun hours. Enquiries are increasing but large systems seem to be slow compared to small systems or water transfer to storage.

Industry expertise and workforce requirements

Irrigation Australia: What are the key skills and expertise required for professionals working in the solar irrigation sector and those entering the workforce?

Stephen: Collaboration required between different businesses and expertise is important. Electrical licenses and certifications are a limiting factor when it comes to larger scale installation.

Collaboration across sectors to accelerate adoption

How can collaboration between irrigation specialists, solar energy experts, and agricultural stakeholders be fostered to accelerate the adoption of solar irrigation?

Stephen: Much more collaboration is required as the skill sets of these industries are vastly different. This will certainly hold transition back. Bringing both industries together and ensuring successful working relationships will be key.

“If there is no mains power available and costs are high to bring power to that area – this is where solar pumping has an advantage.”

The role of research and development

Irrigation Australia: What role does research and development play in advancing the field of solar irrigation?

Stephen: It has huge potential to demonstrate operational savings and reliable energy.

Advice for farmers considering solar irrigation

Irrigation Australia: What advice would you give to farmers or agricultural businesses considering investing in solar irrigation?

Stephen: Strongly outline your philosophy of operation and requirements of the system so that the best system can be specified to your needs. In some cases, solar power connection to grid is selected due to nearby connection. This is because of the availability of grants and the possibility to use solar power generation to offset running costs, other than irrigation, when not in use. This is where rigorous assessment is required. If there is no mains power available and costs are high to bring power to that area – this is where solar pumping has an advantage.

Funding pathways for solar irrigation: grants, rebates, and government support

As solar irrigation continues to evolve, the need for clear regulation, fit-for-purpose incentives, and cross-sector collaboration will be crucial in driving adoption. Farmers and industry specialists can explore available funding programs to support their transition to sustainable irrigation solutions.

GOVERNMENT FUNDING SCHEMES

Funding programs currently available for solar irrigation:

• Climate-Smart Agriculture Grants – Supports farmers in adopting climate-smart practices, including solar irrigation. Read more here.

• Government Rebates & Loans for Solar – Provides financial assistance for solar installations, including irrigation systems. Details here.

• Agriculture Victoria Grants & Programs – Offers various funding opportunities for Victorian farmers, including sustainability initiatives. Explore them here.

"In 2024, representatives from Lorentz Global Headquarters in Germany, along with the local installer, joined us for a site visit at Gunnible, where we met with Robert to seek feedback on his system and discuss future developments. We believe this is a critical step in ensuring continuous improvement and delivering solutions that meet the evolving needs of our customers and the broader industry." Pat Lee, ReAqua

“We made the shift to solar irrigation back in 2019 as early adopters, looking for the most costeffective and sustainable solution. The initial system had reliability issues, which made things a little difficult. In 2021, we upgraded to a Lorentz solar pumping system and the improvement was immediate. Since then, any unforeseen issues have been quickly resolved thanks to the support from Lorentz Australia and Lambert & Torrens – both of whom have been excellent to deal with. Looking back, the move to solar pumping has proven to be a great decision for us –both commercially and operationally.”

Hoddle, Gunnible Pastoral Company

In the heart of New South Wales' fertile Namoi Valley, the Gunnible Pastoral Company (Gunnible) is blazing a sustainable trail for Australian agriculture. Owned and operated by the Hoddle family, the 1,800-hectare enterprise spans two properties within the Gunnedah Shire and features a thriving 50-hectare citrus orchard, home to 25,000 trees. The farm also supports Angus cattle and cereal grain production. With abundant underground water and long sunny days, the region offers ideal conditions for citrus cultivation – and now, it’s also the perfect environment for a solar-powered irrigation revolution.

Why solar?

The Hoddles faced a common challenge among rural farms – powering a highcapacity irrigation pump without access to the electricity infrastructure needed. The

scale of the citrus operation demands a large 3-phase pump to meet water supply needs. Unfortunately, 3-phase power is not available on-site, and extending the grid to the property would have required a substantial upfront investment, not to mention the burden of high ongoing electricity bills.

The alternative, a diesel-powered system, came with its own drawbacks. Although the upfront capital investment was more manageable, ongoing fuel and maintenance costs rendered this option uneconomical in the long term.

Estimates showed a potential saving of around $80,000 per year by eliminating diesel and grid power reliance.

With these considerations in mind, the decision to invest in solar power was clearly the best solution. Not only did solar offer a way to bypass the costly installation of grid power, it aligned with Gunnible’s sustainable farming goals. The system can also be integrated with a backup generator to guarantee water delivery, regardless of weather conditions.

The system installed at Gunnible is both robust and sophisticated in capability, yet simple to operate. Designed specifically to meet the irrigation demands of their citrus orchard, it includes:

• LORENTZ Solar Pump System comprising:

- PSk2-70 solar pump controller, managing the power delivery to the submersible bore pump.

- Smart Power Blending Unit, allowing seamless integration between the pump controller and a backup generator as required. Prioritising the available solar power, the SmartPSU uses all available solar power and blends in the required generator power to TOP UP the solar as required.

- SmartStart Automatic Remote Diesel Generator Switch. The pump controller is fitted with a sun sensor which provides a continuous measurement of the sun’s irradiation. If the irradiation drops below the required intensity to run the pump within the required specifications, the pump controller will then signal the SmartStart to start the backup generator.

- PS Commander Unit providing remote management and monitoring of the pump system through the LORENTZ Global online platform.

• 90 kW of solar capacity, generated through 272 high-efficiency 330 W solar panels.

• Caterpillar 110 kVA 3-phase diesel generator.

• A 45 kW 3-phase submersible motor, coupled with a 6-stage centrifugal pump.

• This setup delivers an impressive 30 litres per second to 130 psi of pressure – sufficient to meet the farm’s peak irrigation needs.

The LORENTZ solar pump system is controlled remotely via the Netafim irrigation control platform. When water is required, the Netafim controller automatically switches the pump on, ensuring precise and efficient operation. During periods of low solar output or night-time irrigation, the backup generator steps in to maintain water supply without disruption.

Big Savings

Precision irrigation with Netafim drip system

Water conservation and efficiency are paramount in modern farming, particularly in Australia where water resources are finite and climate variability is a constant challenge. Gunnible has addressed this by choosing a Netafim drip irrigation system, known for its precision and sustainability.

Each tree is serviced by eight drippers fed from laterals running down each side of the row of trees. These drippers are strategically placed beneath the canopy, in the shade, to minimise evaporation and deliver water directly to the root zone. This targeted approach not only ensures healthy tree growth but optimises water use.

The system also integrates fertigation –delivering fertiliser directly through the irrigation lines. This ensures nutrients are supplied precisely where and when they are needed, further boosting efficiency and plant health.

Real-world benefits

Since installing the solar-powered irrigation system, the Hoddle family has witnessed significant cost reductions and operational efficiencies. While the solar system required a sizable upfront investment, it was still less expensive than installing 3-phase grid power and comes with far lower ongoing costs than a diesel alternative. Maintenance is minimal, fuel expenses are significantly less, and the farm’s carbon footprint has been markedly reduced.

This forward-thinking approach supports long-term sustainability, both environmentally and economically. It also sets an example for other agricultural enterprises considering how best to adapt to rising energy costs and growing climate challenges.

A model for the future

Gunnible Pastoral Company’s solar-powered irrigation system is more than just a farm upgrade – it’s a blueprint for sustainable agriculture. By leveraging renewable energy and precision irrigation, the Hoddles have maximised productivity while reducing costs and environmental impact.

It’s a testament to what’s possible when traditional farming wisdom meets modern technology, all under the reliable power of the Australian sun.

AUSTRALIA 2025: A guide to digital irrigation decisionmaking and tools

 BY EVE WHITE AND GEMMA NARDONE

Digital technology is developing quickly and is transforming irrigation with realtime data, analytics, and automation.

Tools vary widely in function, but most fall into two broad categories: those that monitor conditions (like sensors and weather stations) and those that support or automate irrigation decisions.

Choosing the right tool depends on the operation’s size, budget, and specific irrigation challenges.

Many tools are now more affordable and user-friendly (even for small-scale farmers) but mastering them still takes time.

Reliable and affordable internet and power supply are essential for real-time sensor data, automation and equipment performance.

AI will increasingly reduce manual labour, but for now, human oversight remains important for decision-making.

One Basin CRC is undertaking targeted research towards accelerating irrigation technology integration and adoption across Australia with Project Advisory Committees that enable involvement.

IRRIGATION HAS MOVED WELL BEYOND VISUAL CHECKS AND MANUAL SCHEDULING. IN THE PAST, GROWERS RELIED ON EXPERIENCE, HISTORICAL WEATHER PATTERNS AND AN UNDERSTANDING OF SOIL AND CROP CYCLES TO GUIDE THEIR DECISIONS. TODAY, DIGITAL TECHNOLOGY IS CHANGING THE GAME, PROVIDING REAL-TIME DATA, FORECASTS AND AUTOMATION TO HELP USE WATER MORE EFFICIENTLY AND MAKE BETTER DECISIONS.

With so many options available, where should growers and irrigation professionals begin? According to Grant Gilmour, Director of Beanstalk AgTech – a company that helps farms and agribusinesses make better use of technology – the starting point is a clear goal. “Is it reducing water use, increasing yields, or managing labour?” he says. “Only once you know that, can you accurately assess which digital tools fit best with your existing infrastructure and farm practices.”

Understanding expectations is also important. “We’re not at the stage where systems are fully automated – anywhere in ag,” says Grant. “Digital tools are mostly assistants, not workers. Like any new piece of equipment, there’s a learning curve – but the benefits are real, especially if the tools come with a process and culture change to get value from them.”

How different technologies fit together

Digital irrigation solutions tend to fall into two main categories:

1. Data collection and monitoring tools –These gather information from the field but don’t directly control irrigation.

2. Irrigation control and automation systems – These use data to support or automate irrigation actions.

These tools can be used independently or in combination, depending on the needs, scale and resources of the operation. While integration often enhances accuracy and efficiency, it’s not always necessary or practical for every context.

2. Irrigation decision and control systems

• Decision-support software (using AI and cloud-based analytics) helps plan irrigation based on real-time and historical data. While many systems still rely on manual implementation, some can integrate with automated controls for more seamless operation.

• Automated irrigation control automatically adjusts irrigation timing and flow based on pre-set parameters and sensor feedback.

• Integrated irrigation networks and smart water delivery optimise large-scale irrigation infrastructure for efficiency and water conservation.

Benefits and misconceptions

Grant says the biggest benefits of adopting digital technology include water savings, yield increases, labour efficiency, and reduced erosion and energy use. “I’ve heard of cases with up to 25 per cent water savings,” he says. “And when you prevent overwatering, you often improve yields too.”

Despite the benefits, common myths remain:

• "It will be too expensive" – Digital systems are becoming more affordable and easier to use, even for small farms.

• "I can automate it all" – Full automation isn’t here yet. Human oversight is still critical.

• "It’s plug-and-play" – Like any equipment, digital tools require learning and time to use well.

AUSTRALIA’S ONE BASIN CRC – DRIVING SMART IRRIGATION INNOVATION

The One Basin CRC is playing a central role in accelerating irrigation technology integration across Australia. This national consortium of over 85 partners is focused on developing smarter, more efficient water management systems that support both agricultural productivity and long-term sustainability.

Its work focuses on:

• Diversifying economic opportunities – Strengthening resilience in the face of increasing water scarcity.

• Transitioning irrigated agriculture for a drier future – Supporting adaptation strategies that align with evolving digital solutions.

• Designing smart connected water infrastructure –Developing systems that maximise efficiency while meeting multiple demands.

Visit the One Basin CRC (1BCRC) website.

Industry input, including from Irrigation Australia, helps guide the 1BCRC's research and ensures new technologies are scalable and practical.

“AI will play a bigger role, using real-time data and historical patterns to make better decisions about when, where, and how much to irrigate.”

Getting started with digital irrigation

When deciding whether to invest in digital irrigation, it’s important to weigh both practical considerations and strategic planning. Here are key points to guide decision-making:

• Cost vs return – Upfront costs may be offset by long-term gains in water, labour, and productivity. Conduct a quick cost-benefit analysis using: (expected benefits – costs) / costs.

• Learning curve – Digital tools require training and time to use effectively. Like any new equipment, there’s an adjustment period.

• Connectivity and power – Real-time systems depend on reliable networks and energy. Failures can limit effectiveness, so backup options may be needed.

• Ongoing costs – Subscription models vary. Review pricing terms, caps, and support provisions to ensure financial sustainability.

• Software updates and compatibility – Ensure updates are included in contracts and remain compatible with your existing systems.

• Support availability – Check if technical support is available in your region, especially for tools with a hardware component.

• Start small – Trialling new tools at a small scale reduces risk and allows time to evaluate compatibility and results.

• Collaborate and learn from others – Work with other growers, networks and industry groups to share insights and accelerate adoption.

• Build strong foundations – Effective use of AgTech depends on having the right processes, training, and digital literacy to interpret data and act on it.

What’s next for digital irrigation?

According to Grant, we’ll see smarter, more precise tools in the next five years. “AI will play a bigger role, using real-time data and historical patterns to make better decisions about when, where, and how much to irrigate,” he says.

As an example, Grant points to plant-based sensors, which can reduce water use by 40 to 60 per cent without affecting yield or quality. Unlike soil sensors, these measure water stress directly from the plant. “That makes them especially valuable for perennial crops,” he says.

Looking further ahead, Grant expects we’ll start to trust AI to make more decisions on its own. “When that happens it will be the big unlock of value. It’s not just about better tools; it’s about building trust in the tools to make the right call in the paddock.”

CASE STUDY

Data-driven insights pour 400% more value into Torbreck wine

Background

Torbreck Vintners, a renowned producer of premium wines in South Australia’s Barossa Valley, is home to some of the world’s oldest Shiraz, Grenache, and Mourvèdre vineyards. With wines ranging from $30 to $850 per bottle, quality is paramount. However, managing vineyards in an environment with just 520 mm (21 inches) of annual rainfall presents unique challenges, particularly as climate variability intensifies.

“The SWAN system allowed us to monitor how the vines were performing and predicted when we were going to need to irrigate. So this allowed us to use the data that we were collecting and make really good management decisions around irrigation.”

Nigel Blieschke, Chief Viticulturist, Torbreck Vintners

Nigel Blieschke, Chief Viticulturist at Torbreck, has spent nearly a decade refining irrigation strategies to combat water stress, improve vine health, and elevate wine quality.

Not just growing grapes

When Blieschke joined Torbreck in 2015, several vineyards were struggling with premature defoliation due to inconsistent irrigation management.

“If we lose canopy to water stress, that is definitely a failure,” he explains. “We had a number of vineyards that were defoliating prematurely before harvest.”

Traditional irrigation methods often relied on intuition and reactive decision-making, which could either result in overwatering – compromising grape quality – or under-watering, leading to vine stress. The challenge was to develop an irrigation approach that balanced vine health with the high standards required for Torbreck’s premium wines.

Data-driven decision making

To refine irrigation practices, Torbreck partnered with SWAN Systems to take a

more analytical approach. By integrating soil moisture data, crop coefficients, and predictive modelling, Blieschke and his team were able to track vine performance with greater precision.

“The block that we were struggling with was making a $30 bottle and often wasn't quite good enough for that. Our aim was not to potentially use more water but was to try and improve the wine quality,” Blieschke says.

With improved irrigation scheduling, Torbreck was able to maintain better canopy cover, mitigate heat stress, and create the conditions necessary for higher-quality fruit.

From $30 to $150 per bottle

Success in viticulture takes time. While early improvements in canopy health were encouraging, the true test was in the wines themselves.

“It's a slow process. You grow the grapes and make the wine, but we don't generally release it until 12 months after. So it's a bit of a waiting game,” says Blieschke.

The impact became clear: one of the vineyards that had struggled to meet the $30 price point is now producing fruit for a $150 bottle of wine.

“We've achieved our goals, which was to again make our vineyards healthier and produce the quality grapes that we wanted.”

Looking ahead

With climate change driving more unpredictable weather patterns – including mini droughts and heat waves – having a responsive, data-driven irrigation strategy is more critical than ever.

“One of the difficulties of being a vineyard manager is actually being able to react quickly to these events and understanding how to manage them,” Blieschke explains.

For Torbreck, this approach is not just about improving individual vintages – it’s about ensuring long-term sustainability.

“SWAN allowed us to still maintain quality and also vineyard health… Because of its predictive ability, it worked very well for us in getting the quality outcome we required while maintaining vine health and yield.”

Virtual energy trading study now open to energy buyers

Deakin University is leading a research project investigating how virtual energy networks (VENs) could support more affordable and flexible access to renewable electricity for households and small businesses/farms that do not have solar panels.

The study is open to energy buyers located in the eastern states, including Victoria, Tasmania and South Australia, as part of the National Energy Market (NEM).

Using peer-to-peer digital trading, the study will explore how community energy exchange can improve value for customers and support grid efficiency. Participants will be connected through a platform that enables them to access renewable energy generated by others – such as neighbours or local businesses – at rates that may be cheaper than traditional retail plans.

Researchers are particularly seeking to recruit energy buyers (off-takers), as energy generators are already well subscribed. Eligible participants must:

• have a smart meter

• be on a plan with a participating energy provider.

Trials will run for approximately six months. Findings will be published in the first half of 2026. Registrations are open and will close once participation targets are met, expected by late July.

To register or find out more, visit deakin.edu.au or contact the project team at venproject@deakin.edu.au.

Irrigation’s role in soil carbon farming: Unlocking revenue and environmental gains

Soil carbon farming is a recognised method for improving soil health while earning Australian Carbon Credit Units (ACCUs).

The value of ACCUs could rise to AU$75 by 2035.

Efficient irrigation design enhances microbial activity, improving soil’s ability to store carbon and retain water.

Precision irrigation in low-rainfall climates can boost soil carbon levels, farm resilience, and access to ACCUs.

The Soil Carbon Method recognises new irrigation as an eligible practice, but regulatory restrictions limit excessive water use.

In 2023 a soil carbon project in Qld earned 94,666 credits.

Introduction

Soil carbon farming is gaining attention as a way to improve soil health while generating revenue through Australian Carbon Credit Units (ACCUs).

The Soil Carbon Method recognises irrigation as an eligible practice, with potential to enhance soil carbon storage and farm productivity. This article outlines the role of irrigation in soil carbon projects, key considerations for implementation, and regulatory needs under the ACCU Scheme.

In a recent report¹ by the Carbon Market Institute, RepuTex (a leading provider of price information and analysis), noted that the value of the ACCU traded market achieved a new high of $1.1 billion in 2024 – up 31 per cent on 2023. At the time of writing this article, Coremarkets.co reported the ACCU spot price as AU$35. Analysis by EY Net Zero Centre suggests that the value of ACCUs could rise to AU$75 by 2035.²

Interestingly, the Carbon Market Institute website says that in 2023, the largest award of ACCUs made to a carbon farming project – of any type – was a soil carbon project in Queensland. The project, on a grazier’s property, successfully sequestered 126,222 tonnes of greenhouse gas across 5,275 hectares of land, earning 94,666 ACCUs³.

Understanding the role of Irrigation in soil carbon projects

Irrigation design and management can directly influence both a farm’s crop yield and the soil’s carbon storage capacity. Irrigation methods vary depending on land, soil, ecological factors, crop selection, and what stock you have. When low natural rainfall limits crop productivity, irrigation becomes an essential tool in soil carbon improvement.

Basically, when irrigation is designed and managed efficiently, soil becomes more conducive to microbial life, increasing microbial activity – resulting in greater carbon storage and water holding capacity.

 MAIN ARTICLE BY CARBON FARMING FOUNDATION, INTRODUCTION/CONCLUSION BY GEMMA NARDONE

SNAPSHOT

In low-rainfall climates particularly, adding precision irrigation can be the key to increasing soil carbon – resulting in carbon credits in the bank, better crop performance and overall farm resilience.

Soil carbon storage and irrigation –what the research says

Importantly, research has shown that soil organic carbon stocks tend to increase in shallow soil layers, while the effects of irrigation on deep soil carbon storage are still being researched.

What does the ACCU Scheme say about the Soil Carbon Method?

According to the ACCU Scheme’s Soil Carbon Method, undertaking new irrigation is considered an eligible practice for your farm (you can see the full list of eligible practices here). It involves applying new or additional irrigation to a property by improving the efficiency of on-farm infrastructure or management practices within the project area.

It is important to note that there are some restrictions around the application of irrigation. For example, the amount of annual or five-year irrigation over a carbon estimation area (CEA) – or the project area – cannot increase by more than 20% of the

amount used during the five-year baseline period. So, you cannot simply purchase an additional water licence and start ramping up your water use to increase carbon.

Steps to take and irrigation techniques to consider for soil carbon projects

Connecting with the Carbon Farming Foundation (CFF) could be a valuable first step in assessing whether a soil carbon project is suitable for your land. You can book a free introductory call with CFF to receive guidance on feasibility, project setup, and access to relevant experts and resources.

Adopting precision irrigation technologies

If you have made an informed decision to proceed with a soil carbon project, your next step might be to implement precision irrigation technologies to ensure that only the necessary amount of water is used, minimising waste and improving efficiency.

By engaging Certified Irrigation Designers, farms can optimise irrigation systems to align with management plans and comply with Soil Carbon Method eligibility requirements.

Other activities to enhance the hydrology of the landscape

Landscape activities

Techniques such as leaky weirs or chain-ofpond streams, contour banks, and erosion control techniques can improve landscape hydrology by slowing water movement and increasing infiltration rates.

Vegetation activities

Strategic planting of deep-rooted trees and shrubs can slow water movement underground, improve water access during dry periods and assist in salinity control.

Conclusion

With increasing pressure to reduce carbon emissions – driven by extreme climate events and economic imperatives – soil carbon projects are becoming a relevant consideration for landowners and irrigators. Understanding their potential benefits, including revenue opportunities through carbon credits, can support decision making.

Towards a sustainable water future: The nine characteristics of future-facing organisations

 ARTICLE PROVIDED BY ARUP

Water at a crossroads

Water is essential to life, underpinning human well-being, ecosystems, and economies. It influences climate patterns and sustains biodiversity. Yet human activities − land use changes, pollution, and unsustainable consumption − are placing unprecedented pressure on global water systems. Climate change and biodiversity loss are manifesting through water crises, from extreme droughts to catastrophic floods, making water central to both the challenges we face and the solutions we must implement.

Recognising this urgency, international conversations on climate and biodiversity increasingly place water at the forefront. The UN’s first Water Conference in nearly

five decades highlighted the need for water to be at the centre of global policymaking. Yet, progress on Sustainable Development Goal 6 − clean water and sanitation − is falling short. The Global Commission on the Economics of Water warns that decades of mismanagement have pushed global water cycles out of balance, calling for a radical shift in how water is governed, managed, and valued.

Organisations worldwide are already rethinking their relationship with water, exploring solutions that emphasise sustainability, resilience, and collaboration. This article identifies nine essential characteristics that future-facing organisations must adopt to help secure a better water future.

The way we manage water is under pressure, with climate change, pollution, and unsustainable use threatening ecosystems and communities.

Global initiatives are recognising the urgent need for better water governance and long-term resilience.

This article by Arup explores how organisations can rethink their approach to water management, focusing on sustainability, collaboration, and adaptability.

1.

Outcomes-focused approach

Historically, water management has prioritised organisational outputs − specific projects or infrastructure developments − rather than broader societal and environmental outcomes. Future-facing organisations must instead align their goals with shared outcomes, such as restoring river health or improving water equity, and work collaboratively to achieve them.

Why it matters. A narrow focus on isolated outputs leads to inefficiencies, duplication of efforts, and missed opportunities for systemic improvements. By shifting towards an outcomes-based approach, organisations can drive meaningful, long-term change and ensure resources are allocated effectively. For example, an organisation aiming for "healthy rivers" must not only improve its own operations but also engage with stakeholders − farmers, industries, and regulators − whose actions impact water quality.

2. Adopting a systems mindset

Water issues are interconnected with broader environmental, social, and economic systems. Future-facing organisations must embrace systems thinking, recognising interdependencies and working across sectors to drive holistic solutions.

Why It matters. Water governance remains highly fragmented, often treating individual issues – like water supply, pollution, or flood control – in isolation. A systems perspective ensures solutions consider upstream and downstream impacts, enabling better

water resource management. For example, integrating urban drainage planning with natural floodplain restoration can prevent downstream flooding while enhancing biodiversity.

3. Building resilience and adaptability

In a world of increasing climate volatility, organisations must embrace adaptive planning to ensure resilience against unpredictable water-related challenges.

Why It matters. Traditional water infrastructure was designed for stability, assuming past conditions would persist. However, extreme weather events, changing precipitation patterns, and rising sea levels demand flexible strategies. Organisations should implement scenario planning, continuously monitoring and adjusting their approaches to remain effective in an uncertain future.

4. A distributed mix of solutions

Relying solely on large-scale, engineered solutions is no longer viable. Future-facing organisations must integrate traditional ‘grey’ infrastructure with catchment-based and nature-based solutions, alongside behavioural changes in water use.

Why It matters. Expanding the range of water management solutions ensures resilience, cost-effectiveness, and environmental benefits. For instance, wetlands can naturally treat wastewater while providing biodiversity benefits, and green infrastructure in cities can mitigate flooding while improving air quality and urban cooling.

5. A total value perspective

Decision-making must account for the full range of social, environmental, and economic impacts rather than relying solely on conventional cost-benefit analyses.

Why It matters. Water-related investments often prioritise financial returns, neglecting wider societal and ecological benefits. Future-facing organisations should adopt multi-capital frameworks that incorporate natural, social, and human capital into decision-making. This ensures resources are allocated to solutions that deliver longterm value, such as restoring wetlands for water purification instead of investing in costly treatment plants.

6. Progressive partnerships

Water challenges require collaboration between governments, businesses, communities, and individuals. Futurefacing organisations must actively build partnerships to co-design, deliver, and fund innovative solutions.

Why It matters. Water management has traditionally been siloed, with public utilities, private industries, and communities operating independently. However, achieving sustainable outcomes demands cooperation. Effective partnerships can unlock new funding models, such as public-private initiatives or market-based mechanisms for pollution reduction, while leveraging community knowledge and participation.

7. A place and community outlook

Solutions must be tailored to the unique characteristics and priorities of local communities, integrating Indigenous and community-driven water management perspectives.

Why It matters. Water challenges vary greatly by location, requiring localised approaches. Engaging communities ensures solutions are socially equitable, culturally appropriate, and more likely to succeed. For example, Indigenous water governance practices – rooted in deep ecological knowledge – can offer valuable insights into sustainable water stewardship.

8. Collaborative citizens and customers

Water users must transition from passive

recipients of services to active participants in water management, contributing to conservation efforts and responsible water use.

Why It matters. Individual actions – such as reducing water waste, preventing pollution, and supporting community-driven conservation – aggregate into significant impacts. Organisations should implement behavioural change initiatives, leveraging technology, incentives, and education to encourage responsible water use. Citizen science initiatives, where individuals contribute data collection, also play a growing role in monitoring and protecting water resources.

9. A robust social contract

For people to support and engage with water management initiatives, there must be trust and accountability between water institutions and the communities they serve.

Why It matters. Public distrust in government agencies, utilities, and private water providers undermines cooperation. Strengthening transparency, accountability, and stakeholder engagement is essential to securing public buy-in for necessary behavioural and policy changes. Social contracts help create shared responsibility,

ensuring all stakeholders play their part in water stewardship.

The path forward

These nine characteristics offer a roadmap for organisations seeking to transition towards sustainable, resilient water management. However, transforming the water sector requires more than just strategic intent – it demands action.

Organisations must assess their current maturity against these characteristics, identifying strengths, gaps, and opportunities for improvement. This might involve shifts in governance, investment strategies, or technology adoption. Crucially, it requires a cultural shift towards collaboration, long-term thinking, and an unwavering commitment to valuing water as a shared resource.

The question is no longer whether change is necessary, but how quickly organisations can adapt to ensure a future where water systems are resilient, sustainable, and equitable for all.

Big changes to supercharge metering and transform NSW water

management

 BY DAN CONNOR, DIRECTOR OF METERING AND LICENSING, NSW DEPARTMENT OF CLIMATE CHANGE, ENERGY, THE ENVIRONMENT AND WATER (NSW DCCEEW).

As it stands, only 63% of licensed water extraction across the state is accurately metered – the NSW Government is working to get this to 95% by the end of 2026.

NSW has launched into a new era of better water resource management thanks to landmark changes to fast-track non-urban metering and deliver big wins for water users, regional communities, and the environment.

In March this year, we streamlined the state’s water regulations, creating clearer and more practical ways for water users to be compliant with metering rules, and ensure licensed water extraction is fairly measured and managed.

The changes also mean it’s never been quicker, easier or cheaper for water users to comply with the rules – and now is the time to act.

So, what are we doing? It all boils down to the Big 4, a quartet of key initiatives we’re implementing now to significantly boost metering rates over the next 12 months.

We are:

• Working to ensure the 400 largest water licenses in the state are brought into compliance as a priority. This group represents only one per cent of licenses, but together accounts for more than 65 per cent of all licensed water extraction in NSW.

• Rolling out the Telemetry Uplift Program, which offers free telemetry equipment and installation for larger water users in inland NSW. To opt in, visit our website now.

Working directly with all water users to ensure metering obligations are placed only on works being used to take water and accurately reflecting this in licensing records.

• Engaging with water users to ensure they understand what metering equipment they need to have installed and by when, and its benefits.

The streamlined regulations come after we held a comprehensive review of the state’s metering rollout in 2023 and 2024 and consulted extensively with hundreds of stakeholders including farmers and irrigators, residents, local governments, agencies, and community, Aboriginal and environmental groups.

They shared their valuable insights, feedback, experience, and expertise, which helped us pinpoint the roadblocks to metering installations and determine how we could make the most effective improvements going forward.

It was clear we needed to sharpen our focus on larger water users, while making it faster and cheaper for smaller users to comply. Because a relatively small number of larger water users make up most of NSW’s licensed extraction, it made the most sense to concentrate our efforts on this group.

But why is accurate metering so important? It's simple: responsible and effective water resource management absolutely hinges on it.

In NSW, water entitlements have been independently valued at $41 billion dollars. Water is an enormous economic driver for our state.

Accurate metering ensures water taken from our rivers, waterways and aquifers doesn’t exceed sustainable and legal limits and that the accuracy of water allocations can be improved.

Moreover, metering means that water users are able to maximise the benefits from their licenses and easily adhere to the rules and it boosts the ability of the regulator to take strong enforcement action when water users do the wrong thing.

As it stands now, only about 63 per cent of licensed water extraction across the state is accurately metered. We know we can’t afford to waste time, especially as we face a drying and more variable climate where every drop of water counts.

By accurately measuring extraction, we support the integrity and effective operation of water markets, including social and economic values throughout regional communities.

Metering also protects environmental water and ensures it can be used to improve the health of our catchments. It adds to our knowledge of how river and groundwater systems operate, improving our ability to manage them.

As we implement these critical changes, the whole water sector is working together with water users to accelerate the metering rollout and improve the standard, scope, and transparency of NSW's metering network.

WaterNSW has launched its DQP Concierge Program, a service available to meter installers who may need support or guidance while in the field. Customers can book an online appointment with a WaterNSW metering expert or by calling 1300 662 077.

Meanwhile, the Natural Resources Access Regulator (NRAR) has engaged with most of the top 400 licence holders and will progress actions to ensure their compliance.

These collective efforts will help us meet our goal of 95 per cent of all licensed water extraction metered by the end of 2026 –about a decade sooner than previously thought possible.

That’s a huge step forward. As it stands now, only about 63 per cent of licensed water extraction across the state is accurately metered. We know we can’t

afford to waste time, especially as we face a drying and more variable climate where every drop of water counts.

As these changes take hold we’re committed to transparently reporting on our progress, with quarterly updates available on our website

Make no mistake; we’re charging full steam ahead to implement a faster, more efficient metering rollout for the benefit of the entire state. It's part of our firm commitment to fair and sustainable water resource management, ensuring NSW leads sustainable water use –now and into the future.

I urge all water users to understand their metering obligations and act now to get compliant – and thanks to these changes, it’s never been easier to get on board.

NSW AND COMMONWEALTH DOUBLE INCENTIVES FOR BATTERIES

The Minns and Albanese Labor Governments are doubling incentives for NSW small businesses and households to install solar batteries and connect them to Virtual Power Plants (VPPs), offering up to $5,000 in upfront benefits for a typical system.

Under the $2.3 billion Cheaper Home Batteries Program, the Australian Government will reduce the cost of a typical installed battery by around 30 per cent, effectively doubling existing incentives for NSW consumers.

On 1 July 2025, the Minns Government increased its VPP connection incentive to up to $1,500, stacking with the Commonwealth's battery incentive to provide extra financial support. For example, a 27 kWh battery (costing just over $30,000) will receive around $10,000 in Commonwealth support, plus $1,500 from NSW if connected to a VPP.

VPPs allow solar battery owners to sell excess energy when demand is high, contributing to grid stability and preventing price fluctuations.

With more than 11,400 battery installations in six months, the NSW scheme has seen widespread uptake. Consumers with eligible batteries installed since November can access the doubled VPP incentive from 1 July 2025.

The Clean Energy Regulator oversees battery installation under the Commonwealth scheme, continuing Australia’s solar expansion with over four million rooftop installations.

The NSW Government will engage with stakeholders to explore future opportunities under the Peak Demand Reduction Scheme.

Irrigation Australia has made a submission to the Building Commission NSW to attempt to address some significant challenges raised by members due to the introduction of new processes and training requirements to become a Water Plumbing – Urban Irrigation licence holder in the state. The current changes see an additional 7 plumbing units of competency introduced over and above the existing Certificate III in Irrigation Technology, as well as some concerns around supervisory and signoff requirements. The department has been responsive to these concerns to date and invited the submission.

HELP FOR COMMUNITIES IMPACTED BY DROUGHT

The Albanese Labor Government is providing an extra $2 million to the Rural Financial Counselling Service (RFCS) to expand access to free financial counselling for farmers and small businesses facing hardship. This funding will allow RFCS to hire more counsellors and reduce wait times in highdemand regions.

This investment follows a $36 million commitment to help farmers and producers prepare for and respond to drought, along with an $800,000 allocation in May for RFCS providers in South Australia and Victoria. Growing demand for financial counselling due to extreme weather underscores the need for expanded services.

Additionally, the Government will convene the 2025 National Drought Forum in Gawler, South Australia, in partnership with the National Farmers’ Federation. These measures build on the Government’s $1 billion in rural support and drought resilience funding to help farmers adapt to ongoing challenges.

QUEENSLAND

The $120 million Wamuran Irrigation Scheme is now supplying Class A recycled water to horticultural farms near Brisbane. The project diverts treated effluent from the Caboolture River, reducing nutrient discharge into waterways while supporting drought resilience. Farmers growing pineapples, berries and turf are among the first to benefit from the scheme, which will provide over 2.6 gigalitres of recycled water annually.

The initiative is led by Unitywater, a statutory authority managing water supply and sewage treatment in the region. A 22-kilometre pipeline transports treated wastewater from the South Caboolture sewage treatment plant to a storage facility at Moodlu Quarry, before distribution to farms. The Scheme is expected to improve water security while reducing environmental impacts on Pumicestone Passage and Moreton Bay.

Recent research from the University of Melbourne indicates that artificial grass can lead to skin burns.

In summer 2024, the research compared artificial grass to both irrigated and unirrigated natural grass, measuring all surfaces against the 48 °C skin burn threshold established by the International Organization for Standardization (ISO 13732-1, 2006).

Tests were conducted in Melbourne in a controlled setting and four private gardens.

Artificial grass exceeded 48 °C several times, whereas both irrigated and unirrigated natural grass stayed below temperatures that could burn skin.

The highest measurement of 72 °C was an artificial grass surface, a temperature that can burn skin within 10 seconds of direct contact (ISO 13732-1, 2006).

Mulch, wooden decking, and artificial grass can cause skin burns by exceeding 48 °C.

Introduction

Artificial grass is being used in more and more parks and gardens in Australia. This is because people think plastic surfaces are easier to maintain, last longer, and may be better for the environment, since they do not need water or fertilisers. However, artificial grass becomes hotter than irrigated natural grass on very warm days. As the use of artificial grass increases, and the climate heats, concerns are growing around the risk artificial grass holds for skin burn and heat stress. The risks are greatest in private backyards where children, the elderly, and pets are exposed to high-risk surfaces.

The research

To understand the ground surface temperatures and skin burn risk of artificial grass as compared to irrigated and

Surface temperatures and burn risks: artificial vs. natural grass

unirrigated natural grass, researchers at the University of Melbourne established a controlled field experiment at Burnley Campus and at four private backyards in northern Melbourne.

Nine plots in the controlled experiment (Figure 1) were fenced to mimic a 36 m2 backyard, with three plots for each surface type (artificial grass, irrigated and unirrigated grass). A climate station was installed at the centre of each plot to measure air temperature and other data. The plots were continuously measured using infra-red temperature sensors (SI111-SS, Apogee, accuracy: ±0.3 °C). Natural grass areas were mowed every two weeks and irrigated plots were watered daily at 1:00 pm, receiving 4mm of water from Hunter MP1000-90 Rotators positioned in each corner and a Hunter MP1000-360 Rotator at the centre.

The controlled field experiment ran for 51 days from January 28 to March 18, 2024. To assess the risk of skin burn, surface temperature was compared against the skin burn temperature threshold (48 °C), as defined by the International Organization for Standardization [1]. This standard states that at 48 °C, solid material can cause permanent skin burn to human adult skin, after ten minutes of contact.

Ground surface temperatures and skin burn risk

The artificial grass was hottest from 10:00 am to 4:59 pm, with an average temperature of 49.9 °C, compared to irrigated natural grass which averaged 29.9 °C and natural grass without irrigation, which averaged 31.7 °C (see Table 1).

WERE CONDUCTED

NATURAL AND ARTIFICIAL GRASS AT BURNLEY CAMPUS, UNIVERSITY OF MELBOURNE.

The average and highest temperatures (from 10 am to 5 pm), measured in a single hour for artificial grass, unirrigated natural grass, and irrigated natural grass, across 51 days.

The highest temperature recorded for any surface type in a single hour was artificial grass. It peaked at 71.6 °C one hot sunny day when the air temperature reached 39.5 °C. The researchers say that just 10 seconds of skin contact at temperatures over 70 °C can cause permanent burns – a dangerous situation for humans and pets. By contrast, irrigated grass (maximum 38.8 °C) never reached 48 °C.

In the study, it was observed that the average surface temperature of artificial grass exceeded 48 °C for about four hours in the afternoon (Figure 2). The highest average temperature recorded for one hour was 56.4 °C at 3:15 pm local time, while irrigated natural grass was approximately 20 °C cooler at that time.

Figure 2 shows the average and range (shaded area) of surface temperatures for artificial grass and irrigated natural grass over 24 hours. The temperature of artificial grass in Melbourne was above 48 °C, the point where it can cause skin burns, for about four hours each day during the experiment. The surface temperature of irrigated natural grass never rose above the level that can cause adult skin burns.

Do we see the same results in real private backyards?

The researchers measured the ground temperatures in four private backyards of a new housing development off Donnybrook Road in northern Melbourne on two hot sunny days –February 4 (37.4°C) and February 11 (32.7°C), between 2:00 pm and 4:00 pm. They used the same equipment as for the controlled experiment.

Four types of ground surfaces were measured: 1) irrigated natural grass, 2) artifical grass, 3) mulch, and 4) wood (Figure 3).

Artificial grass, mulch, and wood all reached temperatures above the skin burn threshold of 48 °C. The highest temperature recorded for artificial grass in these experiments was 53.5 °C (a high skin burn risk), while the irrigated natural grass reached 41.6 °C.

Conclusion

This research shows that artificial grass in backyards can cause skin burns due to high temperatures that can persist for several hours on summer afternoons. Children are more vulnerable because their skin is at least 25 per cent thinner than adults', and they often play unsupervised in backyards deemed ‘safe.’ Pets are also at risk.

Artificial grass gets hotter than irrigated natural grass because it absorbs about 20 per cent of the sun’s energy, whereas natural grass absorbs only 10 per cent. This raises the temperature of artificial grass far more than natural grass under the same weather conditions. The trials also showed that irrigated grass was noticeably cooler than unirrigated grass, yet both surfaces remained within safe limits for adult skin burn.

The study did not investigate if irrigating artificial grass could reduce the risk of heat and skin burn, presenting opportunities for further research.

In summary, the research shows that artificial grass poses a real risk of skin burn to vulnerable adults, children and pets throughout summer. As Australia gets hotter, these risks will rise.

CASE STUDY

School sports field irrigation upgrade –smart, quiet and efficient

 ARTICLE PROVIDED BY BROWN BROTHERS ENGINEERS AUSTRALIA.

A private school in Melbourne faced an outdated and inefficient irrigation system.

The system, linked directly to the school’s potable cold-water supply, did not have enough flow and pressure for effective irrigation, resulting in uneven coverage and long watering times. It was wasting water and not servicing the natural grass on their sports field properly. A modern pump system was necessary to improve performance and sustainability.

The project team created a smart, compact irrigation system that can be accessed remotely, operates quietly, and delivers enough water in a shorter watering time.

Project at a glance

System design: Cadsult

Installation: Redline Irrigation

Water supply: Potable drinking water

• Challenge: The previous system lacked sufficient flow and pressure, leading to uneven irrigation and water wastage.

• Upgraded pump system: The new system delivers 7.5 litres per second at 650 kPa, using a Lowara 22SVX05HPS Hydro-Pac unit with Hydrovar X variable speed drive (VSD) for improved energy efficiency.

• Water management: Water is redirected to refill two above-ground tanks with backflow prevention, and a flooded suction system ensures consistent pump operation.

• Noise reduction and compact design: Sound-absorbing materials in the pump cabinet minimise disturbances, while the side-mounted Hydrovar X reduces overall system size by 24 per cent.

• Sprinkler system: 93 Hunter I-25 sports field rotors provide uniform coverage, allowing up to eight sprinklers to operate simultaneously without overloading supply.

• Smart remote access: The system integrates Hunter's Centralus Central Control software, enabling grounds staff to monitor and adjust irrigation settings remotely.

“We’ve seen a 100% improvement. There are no more dry patches or ‘donuts’ like we had with the previous irrigation system, and the turf is looking great. ”

A compact, intelligent solution

The new system provides 7.5 litres per second at a pressure of 650 kPa, which satisfies the needs of the area. Three-phase power was already available on-site for field lighting, so there were no supply issues. Water supply was redirected to automatically refill two above-ground tanks, with proper backflow prevention to keep the zones contained. The new pump station received water from a flooded suction system.

A Lowara 22SVX05-HPS Hydro-Pac unit was supplied by Brown Brothers Engineers Australia (BBEA). These units combine Lowara pumps with Hydrovar X variable speed drive (VSD) technology, delivering a compact, energy-efficient solution that comes pre-wired and ready to install.

‘The Hydro-Pac pump station makes it very easy for contractors to supply and install, with all parts mounted to a solid base plate ready for pipe connections’ said Damian Cullen, Principal Consultant from Cadsult.

‘BBEA also provide CAD drawings of every Hydro-Pac build, simplifying the design and installation process.’

To protect the system’s electrical components, an INCA Control Surge Protection Panel was also installed.

Smooth and quiet operation

Noise control was important in this project because the pump cabinet was close to residential homes. Fitted with soundabsorbing material, there have been no noise complaints since.

Additionally, the Hydrovar X’s pipe fill mode gradually fills pipes to minimise noise and prevent sudden pressure changes that could cause disruptions or damage. The device changes the pump's output to meet demand, saving energy while keeping the necessary pressure.

Another challenge was the cabinet’s internal space. The Hydrovar X’s new side-mounted design and user-facing screen reduced the overall size by 24 per cent compared to previous models. ‘This was a huge positive,’ said Damian. ‘Without the Hydrovar X, the pump would have needed an 11 kW motor instead of 7.5 kW, and 8-stages instead of 5-stages.’

Smart design for better efficiency

The new irrigation system, includes 93 Hunter I-25 sports field rotors, positioned to cover the entire field evenly and efficiently.

It can run two areas simultaneously, controlling up to eight sprinklers at once. This means that watering can be completed more quickly, without overloading the water supply or pump.

The sprinklers are connected to underground pipes for watering, so the ground above remains undisturbed. A Hunter ACC2 decoder, with decoder units set up in the field controls each valve. A main valve and flow metre monitors how well the system is working. Benefitting from fewer cables, the decoder is easier to install and fix.

Integrating with Hunter's Centralus Central Control software, staff can access the system from their smartphones or computers. Grounds staff have full control thanks to real-time performance monitoring, alerts, and the ability to make remote adjustments.

Results: Chalk and cheese

The new system is now fully operational, with positive early feedback.

‘The difference is like chalk & cheese,’ said Damian. ‘Grounds staff can apply 8mm of water across the entire ground in just over six hours. Distribution uniformity is excellent, with consistent coverage across the field.’

• The garden blends rainfall and potable water, featuring four ephemeral ponds that capture and temporarily hold water. Installing rainwater tanks or greywater and wastewater systems was unfeasible due to weight loading limits.

• The eastern garden bed has remotely managed plots with irrigation tailored to plant needs. The western bed is watered uniformly for larger tube stock and proven species.

• Flow sensors enable irrigation monitoring via the building management system, with manual checks ensuring proper function.

• Two roof-top weather stations send live data to Melbourne's open data platform.

• During heavy rainfall, the irrigation system can be disabled, as has occurred.

Design and planting

The rooftop garden features two distinct sections:

• The eastern garden bed showcases research plots that test diverse planting mixes, installation techniques, and green roof systems, including both layered and modular approaches.

The western garden bed highlights effective landscaping techniques, showcasing how research transforms into functional, attractive green infrastructure.

To guarantee resilience in tough rooftop conditions, the project team chose noninvasive, climate-compatible plants that deliver year-round beauty and ecosystem benefits. Off-limits to the public, the garden is overlooked by towering high-rises.

Monitoring and evaluation

The University of Melbourne’s Green Infrastructure Research Group is assessing green roof build and maintenance costs, while evaluating long-term performance.

Research garden plots will be monitored for at least 21 months after planting to assess how the rooftop will perform over two summers. Findings will close industry knowledge gaps and promote the wider adoption of green roofs in urban areas.

Traditional owner engagement

Three First Nations groups teamed up on the Green Our Rooftop initiative, focussing on green roof maintenance, culturally significant plants, and knowledge sharing to deepen connections to Urban Country.

Twice the life: The enduring bore pump of Echunga

 ARTICLE PROVIDED BY BROWN BROTHERS ENGINEERING

In the rolling green hills of Echunga, a small town in South Australia’s Adelaide Hills, time seems to move a little slower. For nearly 50 years, a single pump hummed quietly beneath the earth, pulling bore water to the surface to sustain a hobby farm. Installed in 1977, this Grundfos SP10 wasn’t just equipment: it powered the place through decades of hard work, running strong even as the farm split from one property into three.

Echunga has no mains water, a fact that makes reliable groundwater a lifeline for anyone living off the land here. Back when the SP10 was first dropped into the bore,

the farm sprawled across a single plot, its pastures dotted with grazing cattle and fields thirsty for irrigation. Over the decades, the land was carved into three smaller properties, but the pump kept going, faithfully serving each new owner without complaint. Most pumps call it quits after 20 or 25 years - half a lifetime compared to this one. The SP10? It ran for 47, a testament to engineering that defies the odds.

Craig Ritchie knows a thing or two about pumps. He’s been servicing them at Mt Barker Pumps since 1981, just a few years after this SP10 started its marathon.

The original nameplate on the 1977 Grundfos SP10

“Around here, if it’s not broke, you don’t mess with it,” he says with a grin. “That pump was a beast – tough as nails and efficient as anything I’ve seen. It barely needed a nudge to keep going.” When it did need a tweak, Ritchie serviced it to keep it going rather than pulling it out. “Why replace something that works? Saves the customer a few bucks and keeps a good thing running.”

And run it did, with its original motor still spinning after nearly five decades. It wasn’t until 47 years later, that the farm swapped it out for a new Grundfos SP11, a choice driven less by the old pump giving up and more by the promise of better energy efficiency – a critical edge for farmers keeping an eye on rising power costs.

The SP10’s story isn’t just about a pump that wouldn’t die. It’s about what it meant to the people who depended on it. For almost half a century, it delivered water without fanfare, keeping the grass green, the herd fed, and the farm alive through dry spells and wet winters alike.

In a world where equipment often feels disposable, this pump was a throwback – a reminder that quality can endure.

As Ritchie hauled the old SP10 out of the ground, he couldn’t help but tip his hat to it. “You don’t see that every day,” he says. “A pump that runs for 50 years? That’s not just luck – that’s Grundfos.”

Product Overview

Why BERMAD developed the BERMAD Irrigation Management Solution (IMS)

In agriculture, water is everything. So is ensuring that farm infrastructure is working to its full potential. Anything that can prevent in-field issues –especially those that could lead to under-watering – before they happen, is a game changer. That’s the reason for the BERMAD Irrigation Management Solution (IMS): better irrigation control, clearer insights, and peace of mind.

Purpose: BERMAD developed the IMS to help irrigators monitor water distribution, prevent issues early, and optimise farm infrastructure.

Key challenge: Farmers struggled to track water flow to individual blocks, leading to inefficiencies and potential crop damage.

Core innovation: A durable but lightweight flow meter that enables precise, real-time water flow measurement with easy installation and integration.

System advantages: Modular design allows tailored setups, helping irrigators detect and resolve issues before they escalate.

Field-tested reliability: Trials over nearly two full irrigation seasons confirmed accuracy, durability, and effective pressure control.

Pressure management: A pressure reducing valve ensures stable and reliable operation, reducing maintenance risks.

Scalability: The IMS integrates with a remote irrigation management controller.

The idea behind the BERMAD IMS came from a pressing need: irrigators struggled to monitor exactly how much water was reaching each block. Without this data, it was difficult to know whether their micro-irrigation systems were working as designed. And when a problem arose –whether a blockage, a leak, or a pressure issue – it often wasn’t discovered until too late: infrastructure was compromised, crops were affected, and yields were reduced.

A new tool for a new challenge

A key driver behind the BERMAD IMS was the release of the BERMAD M10 MagFlow water meter. Made from glass fibrereinforced plastic, it’s lightweight and easy to handle. What sets it apart is its design: it can be installed with zero pipe length required before or after the meter. That means it fits into tight spaces – like in-field pressure reducing valve stations – where traditional meters simply can’t go.

 ARTICLE SUPPLIED BY BERMAD

The M10 also has no moving parts, meaning less maintenance and a longer lifespan. Its grooved connection makes it compatible with a wide range of systems, and it integrates easily with digital farm control systems. This allows for real-time monitoring of water flow, giving irrigators accurate, up-to-the-minute data – with the required outputs to feed back into a farm irrigation control system to capture and store that data.

What makes the IMS different?

The BERMAD IMS is a complete solution. At its core is the ability to measure the exact volume of water going to each block being irrigated. With this data, irrigators can see whether their systems are performing as intended. If something’s off – say, one block is getting less water than expected – they can catch it early and fix it before it becomes a problem.

This kind of insight helps prevent irreversible damage. It protects crops, saves water, and avoids costly repairs. And because the system is modular, it can be tailored to different setups. You can install an M10 meter on each submain riser, or just one on the main manifold inlet.

Proven in the field

In-field trial results across almost two full irrigation seasons were positive. The IMS worked as designed, delivering accurate flow data and helped irrigators identify issues early.

Pressure tests up to 10 bar – above what you’d typically see in a micro-irrigation setup, were also conducted. The system held up without issue, proving its durability and reliability.

The role of pressure control

Another key part of the system is the BERMAD 100 Series pressure reducing valve, especially the 12T-3” Top Pilot model. This is a seated valve, which means it seals tightly and reliably under pressure. There’s no risk of diaphragm deformation causing leaks.

The Top Pilot valve offers stable pressure control with a simplified pilot. It uses a straightforward dial with pressure mark indicators – so all that’s required is to set the dial to the system’s design pressure. When paired with BERMAD’S air valves – like the C-10 combination air valve and the K-10 kinetic air valve – you get a complete package that manages flow, pressure, and air release.

Simple, smart, and scalable

The BERMAD IMS is easy to order, install, and use. Everything is designed to work together, which saves time and reduces the chance of installation errors. It can also be integrated with BERMAD’S Omega controller – a cloud-based, battery-operated unit for remote irrigation management. With Omega and the IMS working together, you get full visibility and control over your irrigation system, from anywhere.

Final thoughts

The BERMAD IMS was developed to solve real problems faced by real irrigators. It’s about helping farmers protect their crops, use water more efficiently, and make better decisions. With accurate flow data, reliable pressure control, and a modular design, the IMS is a practical solution for today’s irrigation challenges.

Growing strong - cultivating mental resilience in your irrigation career

 BY STUART ALEXANDER

Mental resilience drives success –your ability to manage stress and adapt influences career growth and personal wellbeing.

Balance learning with wellbeing –training is crucial, but maintaining energy and setting boundaries ensures long-term sustainability.

Emotional intelligence. Embrace it! –understanding and managing emotions strengthens teamwork and workplace adaptability.

Burnout prevention starts with awareness – structured breaks, clear boundaries, and healthy habits protect mental resilience.

Networking without exhaustion – focus on meaningful connections to avoid social fatigue while advancing your career. SNAPSHOT

Working in irrigation is rewarding but challenging – whether you're managing complex agricultural systems, implementing urban irrigation projects, or leading install teams and businesses. Regardless of your specific role, your mental resilience significantly influences your professional effectiveness, career trajectory, and overall satisfaction.

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

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

Balancing the professional and personal

Training and professional development are foundational in any industry, including

our own irrigation industry. There’s a constant need to upgrade technical skills, obtain certifications, and specialise in niche areas like sustainable irrigation practices or the integration of advanced technology systems in communities. The commitment to ongoing learning, however, can result in significant stress when combined with daily professional responsibilities and personal life demands.

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

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

Also, it's important to communicate your workload and stresses with colleagues, mentors, family, and friends. Being in a place where we can share openly about our professional demands helps reduce anxiety and creates a supportive environment that fosters greater understanding and assistance.

Adaptability and emotional intelligence – embrace it!

As irrigation professionals we face continual shifts in technology, regulatory frameworks, and those ever-changing environmental conditions – making our adaptability essential.

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

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

Developing emotional intelligence involves finding our emotional triggers, empathising with others, and proactively managing stressors. Consider reflecting regularly on how effectively you engage with colleagues during challenging situations. Are you empathetic, supportive, and clear in your communication?

Cultivating EI not only enhances our adaptability but also significantly strengthens workplace relationships and teamwork.

Recognising and preventing burnout

Burnout is increasingly common in high-demand fields such as the irrigation industry, characterised by seasonal fluctuations in workload intensity, and high expectations when critical infrastructure has broken down.

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

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

As well as taking breaks, creating firm professional boundaries is important in preventing burnout. Clearly delineate your work and personal lives, to ensure adequate rest and downtime. Incorporating healthy lifestyle practices – including regular physical exercise, balanced nutrition, and consistent sleep patterns –will substantially bolster your mental and physical resilience.

Mindful networking and avoiding social fatigue

Networking events and industry gatherings play a significant role in career advancement. They provide opportunities to build connections, gain new insights, and for some, new career opportunities. However, frequent social engagements can lead to significant mental fatigue and physical exhaustion.

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

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

Leadership with emotional intelligence

Effective leadership within the irrigation industry demands more than technical ability. It requires a deep understanding of emotional dynamics within teams. Leaders who regularly ask themselves, "How am I impacting my team's wellbeing and performance?" significantly enhance workplace culture and productivity.

Industry commitment to mental health

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

SPOT THE SIGNS: SELF-REFLECTION FOR MENTAL WELLBEING

Self-reflection allows for faster recognition of issues and prompt corrective action.

Consider these reflection points:

• Am I consistently managing my professional and personal boundaries effectively?

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

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

• Have I recently experienced signs of burnout or prolonged stress? Do my industry interactions and relationships generally energise or exhaust me?

• Am I struggling to maintain professional development?

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

Self-reflection and personal resilience plan

Cultivating mental resilience requires ongoing conscious effort and reflection. Establishing a structured approach for regular self-check-ins will greatly enhance your chances for long-term resilience. Find a schedule that works for you. Monthly is a good place to start, but some of us may need to check in weekly, or daily. It varies on where we’re at in our EI journey.

Mental resilience is essential – not only for individual professionals but for the long-term health and sustainability of our industry. By prioritising mental wellbeing, engaging with support systems, and committing to ongoing reflective practice, you ensure a career that is both rewarding and fulfilling.
