OUR use of mains water has been close to zero litres since 2001, when we installed water tanks. Despite record low dam levels our tanks are still half full.
If more homes were provided with rainwater storage of about 5000 litres per bedroom, the rivers of water that go down the drain every time it rains would instead be captured.
Tanks are a cheaper and better option than energy intensive engineering projects such as the desalination plant and the north-south pipeline. Using tanks, a daily target of mains water usage of less than 20 litres per person is achievable now.
