City West Water

West wyndham recycled water project

We are leading the way in the use of recycled water in Melbourne’s western suburbs.

The West Wyndham Recycled Water Project will deliver high quality, Class A recycled water to housing estates in the Wyndham area, as well as a number of open spaces managed by Wyndham City Council.

Recycled water is currently being supplied to around 3,750 homes in Werribee, Wyndham Vale and Manor Lakes.

The current supply is a mix of drinking water and recycled water. Work is ongoing at our Werribee Recycled Water Plant to bring more equipment online for the supply of a 100 per cent recycled water product in 2017.

The recycled water will come from Melbourne Water’s Western Treatment Plant, where it will be further processed and sent to homes and open spaces in the Wyndham West area through a dedicated ‘purple pipe’ recycled water system.

If you are connected to recycled water, it is important to make sure your recycled water comes out of the right tap. Test your connection in five easy to follow steps by visiting how to check your recycled water connection.

West Wyndham FAQs

Recycled water has a number of environmental, social and economic benefits. These include lowest block water rates, reduced reliance on drinking water and a secure source of water for a range of purposes.

Customers can use Class A recycled water for:

  • toilet flushing,
  • car washing on grassed areas,
  • garden watering (including vegetable and herb gardens),
  • filling water features (such as ponds and fountains),
  • providing drinking water for your pets (ensure you change it regularly),
  • washing machines (for houses built after 1 January 2015).

Customers should not use Class A recycled water for:

  • drinking,
  • cooking or food preparation,
  • bathing or showering,
  • swimming,
  • bidets and sanitary sprays,
  • filling water toys.
If you accidentally drink recycled water, there is no cause for alarm. It is treated to a high standard, meaning the likelihood of falling ill is low. However, if you feel unwell you should consult your doctor.
Similar to drinking water, water quality testing of recycled water will be conducted on a regular basis. We also regularly audit local plumbers to ensure recycled water connections are fitted according to Victorian Building Authority regulations and carry out inspections during the construction of your home.

Recycled water is produced at Melbourne Water's Western Treatment Plant where it undergoes a very high level of treatment to become Class A recycled water. The recycled water then undergoes further treatment to reduce the salt level at our West Werribee facility so that it will suit most types of plants and the soil conditions in the area.

Following treatment, recycled water is supplied through a separate purple pipe to toilets, external taps and in some cases, your laundry.

Households in the Manor Lakes, Riverwalk, Jubilee, Bluestone Green and Harpley estates will receive water in the first phase of supply. Further estates will be brought online over the coming years as the pipelines are extended from the West Werribee facility to newly developed housing estates. This will mean, as residents move into their newly constructed property, recycled water will be available (see following map).

Stage 1 (Late 2016) - Manor Lakes, Jubilee, Bluestone, Harpley and Riverwalk estates.

Water will be available in the Savana, Wynbrook, Alwood, Wollahra Rise estates upon occupancy.

Stage 2 (2018) - Cornerstone estate (subject to further development).

Stage 3 (2019) - Vineyard and King's Leigh estates (subject to further development).

Public amenities such as parks and open spaces, fountains and ornamental ponds will also benefit from the use of recycled water.

City West Water will initially supply customers with a sign for their purple tap advising it is recycled water and unsafe for drinking purposes. It is the customer’s responsibility to maintain the signage and ensure it is legible. These signs can be purchased at your local hardware store.

Although recycled water is not subject to Permanent Water Saving Rules, it is still a valuable resource and should be used wisely.

To reduce the risk of a cross connection between your recycled and drinking water pipes, you should always obtain approval from City West Water prior to carrying out any plumbing works and always use a licensed plumber.

Recycled water usage will be charged at Block 1 levels – the same as the cheapest level of drinking water. These prices are approved by the Essential Services Commission, the independent regulatory authority for water. Residents will also see a recycled water service charge on your quarterly statement which will cover the cost of the additional infrastructure required to supply the recycled water.

The supply of recycled water relies on purple pipes being constructed all the way to the property.  As more homes are constructed between the West Werribee treatment facility and these estates, the purple pipe will be extended carrying recycled water to the purple meter.

This should happen in:

  • The next 12-18 months for Cornerstone residents (early 2018).
  • Approximately 3 years for Kingsleigh and Vineyard residents (mid 2019).
 We acknowledge the delay in providing recycled water to our customers in the West Wyndham area. The necessary infrastructure is now in place and recycled water will soon be supplied through the purple pipes to homes throughout West Wyndham. 

City West Water is responsible for maintaining the water meter (including the recycled water meter) and what is known as the property service pipe for services

You are responsible for the pipe beyond the water and recycled water meters leading into your property. If there is no water meter, or the water meter is not situated at the front of your property, you are responsible for the pipe beyond the stop tap, which is located at the property boundary. A stop tap is the valve that controls the flow of water that enters your property (see image below).

Owners are responsible for, and also pay all costs for:

  • Private fire services from and including the first valve immediately after the water supply main.
    Private extensions or trunk services up to and including the ferrule or ball valve at the connection to our water main.
  • Property services from private extensions.
  • Backflow prevention including any devices and required testing (if applicable).
  • Maintenance of any approved meter pit or cage, installed to protect our water meter.


Yes, as long as you change it regularly. All animals can use recycled water for both drinking and bathing, except pigs. Speak to your local vet for more information.
These are available for purchase at your local hardware store.
