Developers Satterley Property Group and Lester Group are introducing fresh initiatives to help end the reliance on mains water in their residential estates.
Satterley’s latest land release at The Green, Brighton, will be the first estate in Australia to tap a shallow aquifer on the coastal plane to provide non-potable water to its gardens and parks.
Each home will be provided with a waterwise front and rear garden, which will be watered from a series of community bores containing non-drinking water for gardens, streetscapes and public open spaces.
Satterley’s director of property operations, Mike Hollett, said household total water usage was expected to be 30 per cent less that that of a typical metropolitan home, while the City of Wanneroo’s consumption would be about 40 per cent less.
“Under this trial at Brighton, not a drop of drinking water will need to be used for anything other than human consumption,” he said.
From February 2008, home buyers within the new estate will pay an annual flat fee of between $60 and $120 for their water consumption, depending on the size of their land.
Meanwhile, Lester Group is planning to offer homebuyers of its Rapids Landing subdivision in Margaret River a $2,000 rebate as an incentive to increase the capacity of their household water tanks, from a mandatory 2,500 litres to 4,500L.
Project manager Simon Munkton said interested homebuyers would receive the rebate, on top of the state government’s $600 waterwise rebate.
“A typical household can reduce its mains water requirements by around 70 per cent if the tank is connected to the toilet and washing machine alone, and up to 80 per cent if connected to the hot water system too,” he said.
Lester Group is also working with the Shire of Augusta Margaret River to have its parks, schools, and sporting facilities irrigated with treated wastewater.
