An irrigation project designed and project managed by Think Water Dunsborough has played a key role in ensuring a client can continue to host an annual international show jumping competition.

Commercial Sales Manager Ian Rogers said the project required the planning for a whole of property irrigation system to ultimately cover 46 hectares of land.

“Stage one comprised irrigation for two international show jumping arenas and a sand arena,” Ian said.

“As the client hosts a show jumping competition every year with competitors travelling from all over the world, arena presentation is obviously an important part of the event’s overall success and an important outcome for the project brief.”

Ian said the project called for a reliable and simple system that would provide recreational level quality turf.

Stage one involved the installation of a 56kw Yanmar diesel driven Davey ISO pump, approximately 3000 metres of pipe work from 80mm to 200mm, a Hunter ACC controller, wire control cabling, 100mm Bermad solenoid valves and a mix of Hunter ST1600 pop ups and ST1600-BR guns on risers.

The second stage, which is also complete, involved extending the 150mm Cl12 PVC mainline and 2 wire cabling by 500 metres to encompass 5 additional agistment paddocks.

Work on the third and final stage has commenced and will start bringing further paddocks under irrigation on an ongoing basis.

Ian said stages one and two were completed within an eight-week timeframe.

“But the entire life of the project is about three-years,” he said.

While the system that has been installed is large in area and component size, Ian said it was less complicated than a domestic irrigation system.

“The main maintenance item will be scheduled maintenance on the diesel motor,” he said.

“Importantly, the project has reduced man hours, about 40 hours a week, as there is no longer a need to move irrigators. It has also provided additional feed grass and agistment capability, increased irrigation uniformity, reduced water use per hectare and reduced peak power use.”

Ian completed the design, specification and project management work, while the installation was undertaken by South West Agricultural Ground Services, a local contracting firm. “This was the largest project undertaken by Think Water Dunsborough,” Ian said.

“The successful outcome will allow us to compete with larger companies for this type of work going forward. Both the client and Think Water Dunsborough are very pleased with the outcomes achieved. We have delivered a system that provides excellent coverage at lower than design pressure with resultant fuel savings.”
