Lower water bills

Back to Resources


The factsheets, case studies and articles in this section are all about saving water and lowering your water bills.

If you live in a metered water area, you can save on your water bills by using less water - this can be a significant saving.  By reducing your water use, you will also reduce overall demand for water and run a lower risk of water charge hikes to pay for further development.

If you live in an area where water is paid through rates, reducing your water use contributes to lower demand for water and means you are less likely to face rates rises related to capital works for further water supplies or for water treatment and reticulation.

Whether metered or not, you will save on energy costs by reducing in-house hot water use.  As an added bonus, an onsite water supply means you can be self-sufficient and resilient in times of water shortage and supply disruption.

Typically, most water is used toilets and bathrooms, with washing machines and garden watering close behind.

Typical water use

Water efficient tapware, showers, toilets and appliances are easy ways to save water.  You can also consider reusing water through greywater or rainwater systems.
