Water Wise City

Rainfall in Western Australia has decreased so dramatically that dams are no longer able to supply water, and millions of dollars have been invested in desalination plants to 'manufacture' water to prevent water shortages. In 2015, almost half of all drinking water was made by desalination plants, and the other half was provided by extracting  and purifying groundwater.

The City works hard to reduce unnecessary water use, however the maintenance and operation of the City's facilities, aquatic centres, parks and reserves require large amounts of water.

City Scheme Water Consumption

Each year the City uses around 155 million litres of scheme (drinking) water to operate its buildings and provide services for residents. Scheme water represents just three percent of the City's total water consumption, and the main users of scheme water were aquatic centres (16 percent), community centres (14 percent) and reserves (11 percent). The City has an ongoing program of upgrades to improve the water efficiency of its buildings such as installing dual flush toilets in public faciltiies, and swapping taps and showerheads to low-flow options.

City Groundwater Consumption

Groundwater accounts for 97% of the City's total water consumption. Each year the City uses 5.3 billion litres of groundwater to irrigate its parks and reserves.  The volume of groundwater that the City is permitted to use is determined by the Department of Water. By taking a number of water-savings actions such as watering turf only exactly as much as needed, automatically turning irrigation off after rain, and continually upgrading the City's irrigation systems to make them as efficient as possible, the volume of groundwater used each year is generally between 85% and 95% of the volume permitted.

Water Smart Parks

The City's award winning Water Smart Parks program is reducing water use by replacing surplus grass with water-wise natives, retrofitting wasteful irrigation systems, and using moisture probes so that we only water when the soil is dry.

Community Scheme Water Consumption

Stirling residents use over 20 billion litres of scheme (drinking) water between them each year. Nearly half of all this water is used in the garden to irrigate water-hungry plants and lawn. Replacing unused irrigated grass in front gardens and on verges is an easy way for residents to help conserve our previous water supplies and save themselves some money from reduced water bills too.

Community Groundwater Consumption

A further 9 billion litres of groundwater are used each year by those Stirling residents with bores, to water their lawns and gardens.  On average, a household with a bore will use 4 times as much water on their garden as they will use in their home: an average household without a bore uses an equal amount of water on their garden as in their home.  

Free offers to help residents save water

The City of Stirling has a range of free offers for residents to help them save water at home and in their garden. These include:

  • A waterwise verge makeover;
  • Waterwise native plants to atract wildlife  to your garden;
  • A healthcheck for your irrigation system; and
  • A water audit of your home to identify leaks and opportuntities for water savings.
