The Department of Water and Environmental Regulation鈥檚 (DWER) Waterwise Cities Program Manager Winsome MacLaurin said it is also an opportunity for homeowners to reflect on how they can be more sustainable in their own water use.
鈥淎 sustainable house is a waterwise house,鈥 Ms MacLaurin said.
鈥淎nd with climate change meaning less rainfall and increased temperatures it also means our water supply is impacted.
鈥淭hat is where a sustainable house can help householders to reduce their water use.鈥
Australians are the greatest per capita consumers of water, using an average of 100,000L of freshwater per person each year.
This figure increases tenfold if the water involved in the food and products we consume is included.
Reducing water consumption in the home is a simple and easy way to decrease water bills and something anyone can do to reduce the impacts of climate change.
鈥淭he shower is typically the biggest water user, followed by the toilet and laundry,鈥 Ms MacLaurin said.
鈥淓ffective strategies include choosing water efficient showerheads, toilets, appliances and taps.
鈥淥utside the home, strategies include choosing local indigenous plants that are adapted for local growing conditions, mulching, and using water efficient irrigation systems.
鈥淣ew homes can be designed to be water efficient and in existing homes water demand can be reduced with renovations and minor upgrades.鈥
The national Water Efficiency Labelling and Standards (WELS) scheme requires certain products sold in Australia to be registered, rated, and labelled for their water efficiency.
鈥淟ook for the WELS label as a guide for choosing showerheads, toilets, washing machines, dishwashers and taps. The higher the star rating the more water efficient the product.鈥
