City West Water

Water supply management

We are providing sustainable water services to enable a healthy, liveable and prosperous Melbourne.

Why water supply management is important

Melbourne’s water supplies have traditionally been sourced from protected catchments surrounding the city. A growing population and a projected drying trend in our climate mean that in addition to focusing on using water efficiently, we will also need a broader range of water supply sources.

We have a number of established programs to prevent water losses in our system and help our customers use water efficiently. We are adopting Integrated Water Cycle Management to introduce a broader range of fit for purpose supply solutions that can contribute to cleaner waterways and lower energy use.

What we are doing about it

We are working hard to ensure there is enough water for today, tomorrow, and for our environment. A number of our programs are shown in the following table. Successes to date include:

  • Recycling wastewater from our Altona Treatment Plant to supply industry, golf courses and local council.
  • Mining of a sewer to water Sunshine Golf Course.
  • Harvesting stormwater to protect waterways and water local sports grounds.
  • Working with local councils to ensure availability of water for the urban environment.
  • Helping our business and residential customers improve their water efficiency.
  • Commencement of West Wyndham Recycled Water Project to provide recycled water for home toilet flushing and garden watering in addition to traditional potable supplies.
