The Australian Bureau of Statistics estimated that the Perth metropolitan area had a growth of 3.2 per cent in 2008-09. This population growth rate is the fastest of any metropolis in Australia.
There has been a lack of rainfall runoff in Perth and availability of groundwater is declining, particularly in the north west corridor due to the supply of drinking water from the Gnangarra mound.
‘The Green’ at Brighton is the fourth village of Satterley’s Brighton development in the City of Wanneroo. Approximately 1,100 lots and 10 public open spaces are located within the development area.
The development has installed a reticulated non-drinking water or dual reticulation system which delivers non-drinking water supply for the irrigation of public open spaces and private spaces using groundwater from the superficial aquifer. An onsite weather station with moisture sensors is connected to five bores and has a central controller which determines the watering schedule. The system is pressurised only between 10pm and 6am to reduce water loss through evaporation.
