Manningham is widely recognised as an innovator and leader in local water management. The challenges posed by climate change require a collaborative and integrated approach by Council and the community to develop long-term sustainable solutions to managing water supply and protecting our waterways.

In partnership with lead water agencies, Council is committed to the:

  • Sewer Backlog Program rollout
  • Doncaster Hill Smarter Water Planning
  • Living Rivers Stormwater Program

Grey Water

Greywater (all non-toilet household wastewater) can be a good water resource during times of drought and water restrictions, but its reuse can have health and environmental risks.

Greywater is domestic wastewater from the laundry, kitchen and bathroom. Toilet wastewater is known as blackwater and is not suitable for domestic treatment. Greywater with low levels of contamination can be used on your garden. Rinse water from your washing machine is the most suitable greywater to divert to your garden provided you use low phosphorus detergents.

Permits and safe use of greywater

You will need a septic tank permit from council to install a permanent system to collect, treat and reuse greywater. The system must be EPA approved.

No permit is needed for a simple, temporary diversion system. A permanent diversion system (that doesn’t store water for more than 24 hours) needs to be installed by a licensed plumber.

An Icon for application/pdf Application to Install or Alter Septic System (604.6 KB) will be required with detailed plans and the appropriate fee to our Approvals and Compliance Unit, Manningham Council,
PO Box 1, Doncaster, Victoria 3108.

For more information, please refer to the EPA's septic tanks code of practice or our Icon for application/pdf design options for the installation of septic systems (604.6 KB). A permit must be granted prior to any works commencing by a registered contractor or plumber.

Rainwater tanks

Installing a tank to capture rainwater from your roof is a great way to supply water for uses including flushing toilets and watering your garden. Rainwater tanks can also help you save money on your water bill.

For more information view  or find out about the Building Permit requirements.


All new homes are now required to achieve a house energy rating of five stars for building fabric and have either a solar hot water system or a rainwater tank. For this purpose, rainwater tanks must have minimum capacity of 2000 litres.

Water saving showerheads

On average, 30% of all household water usage is in the shower. Installing a water efficient showerhead can save around 11,000 litres of water per household each year and reduce the energy required to heat the water - reducing greenhouse gas emissions.

Bring in your latest Yarra Valley Water bill and old showerhead to our customer service and pick up a free water efficient showerhead.

Waterwatch program

Waterwatch is a citizen science program for monitoring waterway health.

Waterwatch volunteers get involved in exploring and protecting their local waterways by collecting water quality data that contributes to scientific research, management planning and on ground actions that improve the health of our waterways. 

Manningham volunteers have been collecting and undertaking surveys and observations for over 10 years. The information collected has been helping improve local waterway health.
