With a little bit of help from the Water Corporation, about 3,800 Kalgoorlie-Boulder households used 100 million litres less water compared with the same eight month period last year.
Water Minister Mia Davies today congratulated the households that took part in the water efficiency program and said the savings were the equivalent of more than 44 Olympic-sized swimming pools.
"The savings were achieved through the Liberal National Government's Waterwise Towns Program, delivered through the corporation. It offered personalised water use advice to households through a series of letters or emails based on information gathered through smart water meters," Ms Davies said.
"Smart water meters allow households to access detailed information about their water use through My Water, enabling them to identify spikes in use or continuous flows which could indicate a leak."
Reducing water use forms part of the State Government's Water Forever plans to secure water supplies in the drying climate.
The Minister said the overall reduction in water use was due to the dedication of participants to save water in the drying climate.
"The program has been a huge success with households getting involved through analysing patterns in their water use, making small changes and seeing a decrease in their water use as a result," she said.
"A number of customers were able to identify leaks at their properties and others simply enjoyed being part of the community effort to reduce water use."
Kalgoorlie-Boulder forms part of the Integrated Water Supply Scheme which supplies water to Perth, the Goldfields and Agricultural Region and parts of the South West
About 20,000 households in Eaton, Australind and Mandurah also participated in Waterwise Towns programs, saving 320 million litres of water
