Understanding my water use

Changes in season, automatic watering systems, extra people living in the house or an undetected water leak can all impact your usage and ultimately your bill.

 

To help you track your usage we include a graph of your usage on your bill, you can also review your full usage history by signing up to epayplus.

Warmer seasons

As you’d expect, water use tends to increase over the warmer months so remember to compare your usage with the same time last year, rather than with your previous bill to track your household trends.

Automatic watering systems

Automatic water systems are the most common explanation for unexpected water use. Check if your automatic watering systems are operating and turn them down or off if you would like to reduce your water use. Please be aware that on average an irrigation system will use around 25 litres of water per minute̶—that’s 1500 litres of water in a one hour period! Check out the Canberra Plant Selector to fill your garden with plants that require less water and are best suited for our local climate.

Extra people in your house

Did you know that if you have two extra people in your household can increase your water consumption by roughly 400 litres per day, which will add up if they stay for a week or two.

Leaks

Leaks can occur anywhere on your property ‒ inside and outside ‒ and may be hidden from view. A slowly dripping tap can lose about 5,000 litres of water over a three month period. How to check for leaks.

Read your meter

Another way of checking your water use is by reading your water meter regularly. You can detect any issues by reading your water meter frequently and calculating your own average daily usage. Not sure how to read your meter?
