What can you do?

Reduce your demand

Using less water means you reduce your water footprint and the demand on the water supply system. This can result in cost savings for you and for those maintaining water supply infrastructure.

Things you can do:

  • fix leaking taps or running toilets. A slowly dripping tap can cost over $70 per year
  • don’t let the tap run while cleaning your teeth and save about $15 per year
  • keep your showers short and save between 7-20 litres per minute
  • install water efficient products with high WELS star ratings
  • create a water efficient garden by using native plants, using a hose with a trigger nozzle and mulching

Many of these suggestions will also reduce your energy use and save you money.

Use rainwater and grey water

On average, more water falls on the roofs, roads and paths across Melbourne than we use in a year. By catching and using the water that falls on your roof you’ll reduce the amount of drinking water you use. You’ll also have an alternative source of water ready to use when there are water restrictions.

Things you can do:

  • install a water tank for flushing toilets, washing cloths and watering gardens
  • install a grey water system for flushing toilets and watering gardens

Treat and reuse wastewater within your business

Businesses can recycle and reuse their own wastewater although regulations apply.  For further information visit City West Water at http://www.citywestwater.com.au/business.aspx

Water saving products

How do you know if a product is efficient?

To find out how water efficient a product is, check its Water Efficiency Labelling and Standards (WELS) rating. WELS is a national standard that allows consumers to compare the water efficiency of different products. All showers, taps, toilets, washing machines and dishwashers are required to have a WELS rating.

There are slight variations in the look of WELS labels on different products but they all share two key features:

  • a star rating
  • water consumption or flow figures

Find a product

For an extensive list of WELS rated products see the following website:

http://www.waterrating.gov.au/ or check the labelling on appliances in your local retail outlet.

Water efficient gardens

My Smart Garden

Hobsons Bay City Council’s My Smart Garden program helps residents to use water wisely in the garden and create productive gardens that provide food, shelter and habitat for wildlife. For free workshops and other events, gardening advice, prizes and discounts from local nurseries join My Smart Garden.


A raingarden resembles a regular garden but with a major difference - it receives rainwater from hard surfaces such as a downpipe from a roof, paved areas or roads. The soil, gravel and plants in a raingarden reduce the flow of water that washes pollutants such as dog droppings and fertilisers into our creeks and bays. Importantly, it means valuable rainwater is directed into your garden.

Raingardens are self-watering gardens and don’t need to be watered like a regular garden. When planted with native species, raingardens are low maintenance.

For more information on raingardens and how to build one, visit Melbourne Water's website at www.melbournewater.com.au/raingardens. Remember to register your raingarden so that you can help meet Melbourne’s target of building 10,000 raingardens.
