Water efficient fixtures in dwellings
Installing water efficient fixtures and fittings around the home can save water, and money on water bills.
All toilets must be a minimum 4-star dual flush (as rated under the Water Efficiency and Labelling Standards (WELS) scheme) in:
- new houses and townhouses (class 1 buildings)
- sole-occupancy units in multi-unit residential buildings (class 2 buildings).
All showerheads and tapware must meet a minimum 3-star WELS rating.
These requirements don't apply to renovations.
New and replacement garden irrigation systems in areas serviced by a water service provider must comply with the Efficient irrigation for water conservation guideline (PDF, 7MB).
Landlords of rental properties can pass on full water consumption costs to tenants if:
- the building has individual meters
- water efficient fixtures (showerheads, toilets and tapware to kitchen sinks, basins and laundry tubs) are installed.
Charging arrangements must be stated in the tenancy agreement.
