See how much water and money you could save each year
The Water Saving Potential Calculator helps you understand how much water—and money—you could save by improving everyday water-use habits and upgrading to water-efficient fixtures. By analysing household size, usage patterns, and efficiency measures, this tool provides a clear estimate of your potential water savings.
Whether you’re looking to reduce bills, protect the environment, or meet sustainability goals, this calculator shows where meaningful water savings can be achieved.
Water is a valuable and limited resource. Reducing unnecessary water consumption helps:
Lower household or business water bills
Reduce energy use associated with heating water

You simply enter information such as:
Number of occupants
Current water usage habits
Type of fixtures and appliances
Outdoor water use (if applicable)
The tool then calculates:
Estimated water savings (litres or gallons)
Potential reduction in water bills
Long-term environmental impact
Low-flow showerheads
Efficient toilets and taps
