Solar Pumping System Benefits Stock
Location: Alpha, Central Queensland Water
Water Source: Dam
Farming Operations: Organic Beef Cattle
Total Eden Rockhampton were commissioned to design and install this 6480 watt Lorentz solar pumping system in Alpha, located 439Km west of Rockhampton in Central Queensland. The 15,417 Ha property is home to 2000 head of organic beef cattle, who require a consistent supply of drinking water to ensure optimal health and growth of the herd.
Drawing water directly from an existing dam, the system consists of 24 x 270watt solar modules supported in a clenergy 24 module fixed array frame. The system is operated via a Lorentz Ps4000 Solar controller, including Aquatron 240V back up box with redundancy, ensuring a consistent water supply to the property. The SJ8-15 submersible Lorentz Centrifugal pump is floated via a Lorentz dam float to keep the pump from pumping mud at the bottom of the dam. By floating the pump in the cleaner water, there is a reduced risk of sediment and debris entering the system.
The system pumps approximately 100,000 litres of water each day with a total dynamic head of 24 metres. The two-kilometre mainline, comprised of 90mm poly, pumps water from the dam to a turkey’s nest on a high point of the property. From here the water is gravity fed throughout the property through a network of 75mm poly pipe.
In addition to supplying stock water the solar pumping system is utilised by the homestead to maintain the gardens and outdoor areas around the home.
Automating Irrigation on Cotton
Location: Dubbo, NSW
Water Source: Macquarie River
Farming Operations: Cotton
Flood irrigation has long been the standard for the cotton industry and this property in Dubbo was no exception. Following years of drought and rising water costs, the owners made the decision to install a pressurised overhead irrigation system to grow their crop. Nutrien Water were selected to design, install and commission the overhead irrigation system comprising a mix of centre pivot and lateral move irrigators. The switch would not only increase water use efficiency but would also provide greater control over irrigation scheduling.
Due to the presence of power lines in part of the property the design included a single Valley centre pivot and two linear move irrigators, in addition to a new pump station to supply water to the irrigators. The 470 mm galvanised centre pivot is equipped with Nelson A3000 sprinklers across 10 spans and irrigates and area of 70 hectares.
For the remainder of the property the shape of the blocks, previously irrigated by flood, lent themselves to the use of lateral move irrigators. The two galvanized linear move irrigators were also fitted with the Nelson A3000 sprinkler package. Linear one consists of 10 spans, is 500 m in length and irrigates 63 hectares at a flow rate of 113 litres per second. The ditch feed end-cart with buried wire guidance system is powered by a Cummins 200 HP diesel engine and is controlled remotely via the Valley Autopilot control panel.
The second linear move irrigator delivers water over 65 hectares at a flow rate of 120 litres per second. This 14 span, end fed machine is also fitted with the Nelson A3000 sprinkler package for controlled water delivery.
Agsense 3G based telemetry was installed on both the pivot and linear move machines to allow for remote operation from a laptop or smart device, also known as ‘mobile farm management’. The grower has the ability to control and monitor the machines remotely and receives updates on irrigation events in real time.
To support the pivots, a new Southern Cross 110 kw pump station was installed. The pump station delivers 112 litres of water per second to the pivot, that’s an equivalent capacity of nine and a half megalitres per day. A slipway was designed and manufactured on site at the Dubbo facility, to accommodate the new pump and allow it to be extracted during high river levels.
City of Perth Takes Control
Location: Perth, WA
Operations: Municipal Parks, Gardens and Open Space
Nutrien Water was selected by the City of Perth to deliver a new Centralised Irrigation
Management System. The goal of the project was to bring the city’s network of parks, gardens and open spaces into a single platform, allowing the parks team to remotely program, control and monitor irrigation events.
With the city of Perth hosting numerous events across these public spaces throughout the year, it was vital they have direct access to re-schedule, delay and shut off irrigation in certain spaces from a central location.
The Rainman SCADA based Central Control Platform from Aquamonix was chosen to deliver the desired outcomes in optimising and improving the City of Perth’s irrigation system. In total 107 existing individual controllers were swapped out and replaced with an integrated network of control stations, all connected back to a central location.
The system incorporates waterwise irrigation features, including flow meters, soil moisture sensor, pump and weather stations. Each of these inputs provides real time feedback on the performance of the system and irrigation events. This data is collected and analysed providing value insight into water use efficiencies, which can be utilised to update watering schedules.
New Life for The Pines Golf Course
Location: Hope Island, QLD
Operations: Golf and Country Club
Sanctuary Cove Golf and Country Club’s premier golf course has been rejuvenated thanks to new irrigation works completed by Nutrien Water.
Nutrien Water Nerang was commissioned to renew the 30-year-old The Pines golf course irrigation system at Sanctuary Cove Golf and Country Club on the Gold Coast.
The irrigation system was originally installed in 1988 and had reached the end of its lifespan, so it was decided to replace the whole system.
Working closely with the club’s Golf Course Superintendent Paul McLean, Nutrien Water’s Project Manager Steve Moncrieff headed up the works, which began in October last year and were completed mid-August.
The project was done sequentially, with the team completing one hole of the 21-hole golf course at a time, which allowed the club to continuously offer its members an 18-hole course.
“Whilst we replaced the system, we had to make sure the construction didn’t impact the entirety of the old irrigation system; it was a requirement to keep the existing system as operational as possible so that it could keep the rest of the golf course in playing condition,” said Steve.
The project involved a complete upgrade of the irrigation system including new main line, lateral lines, isolation valves and Infinity™ sprinklers incorporating a Toro Lynx™ Central Control system, allowing the club to have full control of the irrigation system.
“The new system enables the club to apply the right amount of water every time it irrigates, based on an optimal water window and time frame the central control system establishes,” Steve said.
“With the new materials we have used, this new irrigation system will water the golf course for the next 30 years or more.”
Steve explained how the irrigation system was like a human body and required continued upkeep and care.
“It's like a body – there is a pumping heart, which is the pump station. Then there are the pipes, which are like veins, ensuring water is being delivered around the golf course. And you’ve got the brain, which is the computer system,” Steve said.
“It's not a set and forget system, there's always continual, preventative maintenance needed.”
