Rainwater tanks are a great way to reduce the demand of the town water supply, reduce stormwater runoff and achieve more sustainable development.
Council supports and encourages the installation of rainwater tanks for new freestanding houses built on properties larger than 250m2 and for new commercial buildings. However, they must meet certain building, plumbing and drainage requirements.
Some of these requirements are:
- Tanks must be set at one third full and topped up with town water
- Tanks must be filled via a float at the top of the tank
- Rain banks cannot be used unless there is a reduced pressure zone valve installed
- Tank must be connected to one external tap, all water closets and the cold water tap of the washing machine
For more information on installing a rainwater tank, please contact us and ask to speak with our plumbing team.
The Queensland Development Code (QDC) Part 4.0 Building sustainably, specifies requirements for installing rainwater tanks.
