Rain Water Tanks

The installation of water tanks is encouraged by Orange City Council as an efficient measure to conserve water for household and garden use. The Council provides a rebate to assist residents with the installation of rainwater tanks as a measure to reduce the demand on the town water supply. The rebates are only available to households that are connected to town water supply and to tanks that are not required under BASIX.

For information about rainwater tanks please visit NSW Health to view their comprehensive brochure about rainwater tanks.
