Goals related to recycled water
- Ensure stringent regulatory obligations are met
- Develop alternative water resources, including recycled water, that meet our customers’ current and future needs.
- Contributed 20.9% of the total amount of recycled water supplied in metropolitan Melbourne, exceeding the Victorian Government target of 20% recycled by 2010
- Provided greater supply flexibility for the recycled water supply to Southern Rural Water for the Werribee Irrigation District with 10,946 million litres supplied during the year
- Completed construction works to enable recycled water supply to commence at MacKillop College, Werribee and to the Werribee Technology Precinct recycled water scheme
- Began construction at Melbourne Water’s Hoppers Crossing pumping station to replace with recycled water a 100 million litres of drinking water a year, which is used for pump lubrication and motor cooling
- Supplied 88 million litres of recycled water to City West Water customers for drought relief via a standpipe at the Western Treatment Plant.
- Our ability to supply the Werribee Agricultural Group with sufficient recycled water was constrained due to drought-related algal outbreaks, reduced inflows and related water quality infrastructure limitations
- The Werribee Irrigation District lettuce crop incident highlighted a need for greater understanding of soil and water management
- Cancellation of a public tender for the use of 35 million litres of recycled water in the west due to lower plant inflows.
- Developing recycled water allocation and treatment options for the Western Treatment Plant to meet competing demands and impacts to quality from natural elements
- Improving the broader community’s understanding and acceptance of recycled water
- Reducing and managing salinity levels in recycled water from the Western Treatment Plant
- Reduced treatment plant inflows due to below average rainfall, water conservation strategies and restrictions creating issues with water quality and recycled water customer quotas
- Where possible, replacing the use of drinking water in operating Melbourne Water’s assets with alternative water sources, including recycled water.
