Recent figures supplied by Water Corp show Hills properties are using more water than most suburbs, including the affluent Dalkeith, Nedlands, Claremont and Mosman Park.
In Gooseberry Hill, the average water consumption is 384,000 litres per household, yet in Dalkeith, the average is just 363,000 litres.
Kalamunda used 278,000 litres per property while Mosman Park consumed 287,000 litres.
Bickley’s water consumption came in at 371,000 litres per annum, compared to Claremont’s 239,000 litres.
A Water Corp spokesperson said major factors influencing water use were block sizes, whether new gardens were being established or not, pools, and the number of people in a home.
He said block sizes in the Hills were generally bigger than the rest of Perth, which could account for some of the excess water consumption.
But many of Perth’s more affluent western suburbs also had bigger blocks, which resulted in their water usage being higher than the overall Perth average of 250,000 litres a year.
Yet their consumption was still significantly below the average consumption of many Hills homes.
West Australians use more water than their eastern states counterparts because of the fact that they live in a drier climate.
