How Council is saving water and improving the quality of our water in Brimbank
As part of our long-term projects we need to address the challenges of climate change, population growth and improving waterway health without impacting our reliance on drinking water. We're committed to a whole of water cycle management approach to secure local water supplies, reduce water usage and enhance local waterways. Through our Integrated Water Management Strategy (2025-2035), we've committed to reduce our potable water use, increase our use of alternative water sources, and reduce pollutants entering waterways. Part of our Water Strategy is to aim for water stewardship (using water wisely) and water quality (healthy waterways).
Alternative water sources
Council and Greater Western Water manage multiple stormwater harvesting systems that reduce our reliance on drinking water supplies. It makes Brimbank’s open space more resilient to the impacts of drought and water restrictions. These stormwater harvesting systems are at Cairnlea, Green Gully Reserve, Keilor Recreation Reserve, Keilor Golf Course, Dempster and Balmoral Park. A further system at our Keilor Operations Centre harvests water for washing vehicles and garbage trucks.
Water quality
To further reduce the amount of stormwater pollutants reaching our waterways, Council has installed a growing number of other water sensitive urban design (WSUD) assets including raingardens, swales, tree pits and wetlands. In 2025 Brimbank currently has 153 raingardens, 38 swales, 24 tree pits, 33 wetlands, 21 sediment ponds and 1 pond.
