As Canberra grows bigger with new housing developments and roads, it is inevitable that the volume and frequency of stormwater runoff will increase, due to the introduction of more impervious surface areas (roofs and tarmac).
This is why rainwater tanks are so important. By collecting and redirecting rainwater from the roof to use in your home and garden, you can reduce demand on the ACT's drinking water supply. You can also reduce the amount of stormwater runoff that reaches our creeks and rivers, where it can cause downstream flooding and erosion.
For more information on the benefits of installing a rainwater tank, how to size a tank to suit your needs, how much rainwater different size tanks can harvest, installation and approval requirements and tank maintenance, see the ACT Government's Rainwater tank guidelines for residential properties in the ACT ( 3.6 MB) .
