Manningham Council 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

Water Management

Manningham Sustainable Water Management Plan 2005 - 2015

Water 15 targets a 15 percent reduction in corporate water consumption by 2015.

Manningham has been working to reduce water consumption through a range of water conservation and alternate water source initiatives including:

  • Installation of automated irrigation systems. Computer controlled irrigation systems give better control over ground watering and allow irrigation to be altered dependent on weather conditions.
  • Many of Manningham's sports grounds are being converted to drought tolerant, warm season grasses (such as couch and kikuyu). Once converted it is estimated that these ovals will use up to 60 per cent less water.
  • Use of seepage water and runoff collected in Doncaster Quarry for road construction activities (such as dust suppressions).
  • Installation of rainwater harvesting system at the Council Depot. Almost 500,000 litres of rainwater can be stored in tanks at the Depot and this is used for watering street trees.
  • Water tanks are now being included in new Council building developments (such as Manningham Doncaster Indoor Sporting Centre, Aquarena extensions, and Templestowe Reserve Pavilion).

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.

To confirm whether or not you will need a permit, fill in an online service request form or contact the Health and Local Laws Team on 9840 933.

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 Icon for application/pdf Rainwater tank policy (154.6 KB) or find out about the Building Permit requirements here.


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.


The Victorian Government has rebates for customers who purchase water saving devices. To qualify for a $150 Water Smart Gardens and homes rebate your rainwater tank must be at least 600 litres and installed by a licensed plumber who will provide a copy of the Plumbing Industry Commission (PIC) certificate (where the cost of the tank and associated plumbing is in excess of $500).
