 Water efficiency

Water conservation is essential to ensure continued water supply and reduce demand on infrastructure. Installing water efficiency fixtures and fittings around the home not only saves water, but can also save money on water bills.

Requirements

In new houses, townhouses and units all toilets must be a minimum 4-star dual flush, as rated under the Water Efficiency and Labelling Standards scheme (WELS). All showerheads and tapware must meet a minimum 3-star WELS rating.

New and replacement garden irrigation systems in areas serviced by a water service provider must comply with the Efficient irrigation for water conservation guideline (as published by the former Queensland Water Commission) (PDF, 379KB).

There is no longer a requirement when renovating an existing house, townhouse or residential unit to install water efficient toilets, tapware and/or showerheads to the existing fixtures and fittings of the dwelling.

Rental properties

Since 1 April 2008, landlords of rental properties have been able to pass on full water consumption costs to tenants where the building has been individually metered and 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.
