Water in Melbourne's west

Melbourne's west has had relatively lower annual rainfall than other parts of Melbourne. As an area of rapid urban growth at long distance from traditional water supplies, there is clear rationale for saving potable (i.e. drinking) water in the region.

How far can we reduce demand for drinking water in Melbourne's west?

Under the Werribee Plains Regional Environmental Sustainability Framework LeadWest commissioned a report: Werribee Plains Urban Water: Reducing Potable Water Use

Households use the bulk of potable water supplied to Melbourne's west. 

In our communities every person, every day, can make a huge difference by adopting simple water saving solutions.

Some 44 per cent of potable water can be saved by installing rainwater tanks at homes in existing suburbs across the region.

In new suburbs, the expected water savings are as high as 57 per cent, and
72 per cent if water recycling is deployed in addition to rainwater tanks.

As the home of Melbourne’s largest wastewater treatment plant, Melbourne's west can be increasingly supplied with recycled water.

The Werribee Irrigation District Recycled Water Scheme supplies millions of litres of Class A recycled water to farmers for irrigating crops such as lettuce, broccoli and cauliflower.  The scheme began in January 2005 and is one of Victoria's largest commercial water recycling schemes.

As well as supplying recycled water produced from its own plants, LeadWest Corporate Member City West Water is one of the suppliers of recycled water sourced from the Western Treatment Plant.

City West Water manages the following recycled water schemes:

  • Werribee Employment Precinct
  • MacKillop College Recycled Water Scheme
  • Western Treatment Plant Standpipe Facility
  • West Werribee Dual Water Supply Project
