The use of water tanks in Perth to collect rainwater may help cut your water bills, serve as an alternative source of clean water in times of drought, and help save the environment.

This, in turn, can help reduce water infrastructure operation costs, protect remaining environmental flows in rivers, and make existing dams and desalination plants more efficient.
