Reasons to use rainwater

Rainwater is a valuable natural resource that can be collected for use around the home.

With water restrictions in place in many areas of Queensland, more homeowners are using rainwater to keep their gardens green, wash the car and for other uses around the house.

Did you know?

A rainwater tank can save up to 100,000 litres of water each year, in an average home.

Can I install a rainwater tank?

Yes, anyone can install a rainwater tank if it is for outdoor use such as gardening. However, if you want to use rainwater inside the home (flushing the toilet, cold water for the washing machine etc) you may need approval from your council. Building approval may also be required for large rainwater tanks.

Information for councils

As part of new energy and water-saving laws introduced from 1 March 2006, councils have the option to amend their planning instruments to mandate rainwater tanks for new houses in their region. Councils will have the discretion to allow for local factors, such as rainfall and the demand for water in their area.

Before a council can designate a rainwater tank area, it must justify the need for the tanks, taking into account the costs and benefits to the community.

To assist councils in determining the need for rainwater tanks in their region, a Rainwater Community Benefits Test ( 127 kB) is available
