Shingleback is one of the great success stories of the McLaren Vale region, a story that is being exported to most corners of the world. Award winning winemakers John Davey and Dan Hills know that the success of their award winning wines starts in the vineyard. And a successful vineyard needs a successful irrigation system.
HydroPlan has provided irrigation design and advisory services to Kym and John Davey and their team since they developed their first vineyards in the 1990s. The challenges included the rationalisation and integration of groundwater, recycled water and surface water on their vineyard as it developed in stages, as well as integration with neighbouring vineyards. A great team and a state of the art pumping, filtration, fertigation and control system ensures the great wines keep coming!
There are many reasons why Bunyip Water and the Gawler Water Reuse Scheme has attracted a lot of positive attention. This $22m project harvests stormwater from the Gawler River north of Adelaide and delivers it to urban users in Hewett near Gawler, and rural water users in the western Barossa Valley. HydroPlan were engaged by Bunyip Water as the design engineers and construction managers in March 2015 to help meet stringent Federal Government funding milestones and complete the project by the end of August 2016. HydroPlan will also provide contract Superintendency for 12 months defects liability periods.
In an innovative public-private partnership, a $10.7m grant from the Australian Government, and an $11.3m loan from the Light Regional Council for the capital investment for the infrastructure, with the foundation customer Seppeltsfield Wines providing the bulk of revenue security by entering into long term water supply agreements. They also have options of control over the infrastructure assets after 6 or 10 years by repaying the invested capital. So when the scheme delivers the water it promises everyone wins.
The Barossa is the fifth most renowned wine region in the world but is restricted by limited stormwater, groundwater, recycled wastewater and water imported from the River Murray. This project substitutes 800 ML of Murray water by harvesting up to 1600 ML/a from the Gawler River.
HydroPlan has been fortunate to witness extraordinary leadership by the people involved in creating and steering this project, and copious competence and dedication from the people these leaders choose to work with.
Managed Aquifer Recharge
As part of water security, HydroPlan arranged equipping one MAR well (constructed prior to HydroPlan's involvement) with a pump and a groundwater license. HydroPlan changed the MAR design to target an aquifer further north where conditions for MAR have since been described by regulators as ideal.
MAR is an enhancement that is essential for water security of the GWRS. Trial injection has been completed successfully - watch this space...
The project has led to three awards -
IPWEA - Institute of Public Works Engineers Australasia - Excellence Award, Design and/or Construction of Public Infrastructure - Water
