The Waterwise Rebate Program was introduced to help West Australians to be more water efficient by offering rebates of up to 50% on a variety of waterwise products, from swimming pool covers and irrigation systems to showerheads and washing machines. Already over 260,000 rebates have been processed with an annual saving of 4.6 billion litres of water, which will result in a saving of 52 billion litres of water over the life of the products rebated.
