 Our Water Use

The City as a Waterwise Council

Perth and the South West face a drying climate and uncertain water future which means everyone needs to play their part in water conservation and ensuring we are as Waterwise as possible.

Rainfall in the south west of Western Australia has already reduced by approximately 15% since the mid-1970s, which has resulted in a drastic reduction in how much water flows into the dams which supply Perth and the South West with drinking water.

Between 2001 and 2010 water flowing into Perth’s dams was about 42% of what it was between 1975 and 2000 with climate modelling suggesting a further 7% reduction in mean annual rainfall and a 14% reduction in surface water supply (, 2016). 

This puts our surface water (dams) and groundwater supplies at risk which means less water to supply our communities, lifestyles and more importantly our health.

As such the City recognises its commitment as a Waterwise leader through implementing a Water Efficiency Action Plan to ensure we are Waterwise in our community centres, public open spaces and operations.
This has enabled the City to maintain water consumption at a fairly steady level; a significant achievement in a drying climate with a growing population.
Our Waterwise actions and objectives even help us identify where we use water in our operations and where we can target more water efficiencies.

For example, the graph below shows that we have 31 water accounts which supply water to buildings which are used for aged care or residences and consumed 33% of the City’s total potable water use. This means Waterwise actions can be tailored specifically for the facility use.
Our communities are also known as being Waterwise, with water use per person during 2014/15 being approximately 88 kL per person. This already achieves the City’s and the Water Corporation's goal of maintaining water use to below 125 kL per person.
The City has endorsed its Water Efficiency Action Plan 2016 - 2021 which details the actions the City intends on completing to ensure it remains Waterwise.
Our residents can also remain Waterwise in their homes by following some simple Waterwise tips. This will save you water and money.
  • Stick to your watering days and program your sprinklers to deliver water efficiently (including bores).
  • 22% of total household water use is in the shower – make sure your showerhead is water efficient and taps, toilets and other water fixtures are Waterwise (WELS rated). Also try and reduce your showering time which will save you on water heating too.
  • Check for leaks and fix these as soon as possible (wasted water is also wasted money).
  • Ensure your garden is as Waterwise as possible by grouping like plants together, with a preference of low water required native plants.
  • Check the Water Corporation’s website for more water saving tips or contact the City of Belmont.
