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 you money on your future water bills.

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.

These requirements also apply for existing houses, townhouses or units undergoing an alteration or extension where both building and plumbing approvals are required. All toilets, showerheads and tapware, regardless of whether or not the fixture is part of the renovation, must be upgraded.

Toilets and tapware need to be installed by a licensed plumber. Showerheads may be installed by the homeowner.

New and replacement garden irrigation systems must comply with the Queensland Water Commission’s Efficient irrigation for water conservation guideline.

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.
