Have you received a bill that is higher than normal?

There are many factors that can influence the size of your water bill. If your bill seems higher than normal – or you'd like it to be lower – below are some things to consider.

Check your meter against the meter reading on your bill

Every 2 months, a meter reader will visit your property to read the numbers on your water meter. Sometimes they can make a mistake.

To make sure your meter read is correct check the reading on the back of your bill. You will find the digits for your meter reading, and the date the reading was taken under the ‘meter reading details’ section.

You will see the date the reading was taken under ‘this reading’  the digit numbers next to it is the number that appeared on the meter on that date.

Compare these numbers to the black and white numbers that are on your meter today.

If they are significantly different, please contact us or call us on 13 13 85. If not, check for leaks, find out how to do this by reading the tip below.

Check for leaks

A high bill can sometimes be caused by an increase in water use. This sometimes happens if you have a leak.

Use our leak detection tool  to find potential leaks in your home or garden.

If you have a leak at your property it means that you are wasting precious water.

Leaks are the responsibility of the property owner to repair. In some instances we will refund some of your bill with a leak allowance.

Check your water pricing tier

If your bill is higher than normal then you may have moved into the next water use pricing tier.

The price of water per kilolitre (kL) increases as you use more water across the billing year.

Your bill can get more expensive towards the last part of the billing year – even if you haven’t used more than previous billing periods. This is because the cost per litre is increasing as you move into a higher water use bracket.

To check if the price you are paying per kL has changed , compare your previous bill with this bill.

You will find your cost per kL on the back of your bill under ‘How your water use charges have been calculated’.

If the cost per litre on your current bill is higher than the previous bill then this could explain why your bill has increased. If they are the same continue to the next check point.

Check your water use

Using your bill, check your water use compared to this time last year.

You can see how much water you used in the same period last year on the front of your bill under ‘daily water use comparison’.

If ‘this period’ and ‘this period last year’ are different it means that something has changed in your home.

Below are some of the most common reasons for increased water use.

Seasonal changes

Using more water on our gardens and lawns, running evaporative air conditioning, filling our pools and showering more often in warmer weather also has an impact on our water use.

Our rainfall also affects how much we need to water our gardens.


Reticulation can use up to 130 litres of water per minute!

If you have pop-up sprinklers at 4 stations and run them twice a week for 10 minutes on each station you end up using around 5,200 litres of water.

New lawn or gardens

You may be using more water through extra reticulation or watering if you have new garden or lawn.

New appliances or fittings

Your water use may have increased if you have installed new appliances or fittings including a new dishwasher or washing machine, a new evaporative air-conditioner, a new shower head or a new tap or if you have installed new irrigation in your garden.

Extra people in your house

Your water use may have gone up due to guests having stayed with you or if the number of people living in your house has increased.

Unexplained increases in water use

If you have tried all of the above and still can’t figure out why your water use has increased please contact us so we can help you to investigate further.
