Your Gold Coast water bill issued by the City of Gold Coast as a Water and Sewerage Rate Notice arrives every three months. Currently, every water meter is manually read every three months, with your Gold Coast water bill coming soon after. The cost of Gold Coast water is set every year as part of the budget process with the detailed current water pricing for 2021-22 available from Gold Coast Water.

What are the costs of your Gold Coast water bill?

For most homeowners who use around the average daily water usage of 451 litres, the highest costs in the quarterly Gold Coast water bill are their sewerage and water access service charges. If you look closely at your water bill, you can see that you have the following access charges:

Residential Charges Cost
Sewerage access charge per quarter

$181.03

Water access charge per quarter

$53.02

Total Access Charges per Quarter

$234.05

The usage charges per kilolitre as measured by your water meter are made up of council charges and Queensland Government charges as below:

Residential Charges Cost

City of Gold Coast water per kilolitre

$1.117

Queensland Government water per kilolitre

$3.231

Total Cost of Water per Kilolitre

$4.348

In reality, even if you did not use one drop of water, you would still pay for water and sewerage access service charges of $234.05 every quarter or $936.20 every year.

Our experience is that the average water use of 451 litres or 0.451kL per property shown on Gold Coast water bills is not an accurate guide to your water use.

Most homes with more than one occupant will use 1-2 kL every day. However, remember your water usage will vary every day based on the number of occupants at home each day and their water use behaviours. That is why we recommend you read your water meter weekly, as that will give you a better guide about your average consumption and alert you to a potential water leak.

The actual cost of water dripping from a tap

What will cause your water usage charges to blow out is having leaking water that you are unaware of. Leaking taps and toilets are frequently overlooked and put off to another day. A dripping tap that drips one drop every second will use 40 litres of water a day. The reality is that it becomes 280 litres a week and then 1214 litres a month, and then 14560 litres a year. This is all water charged for on your Gold Coast water bill that you never utilised for any practical purpose.

If we translate the litres wasted to the cost of water, then the numbers become real very quickly.

The actual cost of a leaking underground water main

You can visually see a dripping tap or running toilet, but the real killer to your Gold Coast water bill is your underground water main pipe leaking. For residential users, these are usually leaking polypipe water mains that were never installed correctly when the house was built. Only occasionally is a water leak apparent and bubbling to the ground. Most of the time, they are a silent Gold Coast water bill killer leaking 24/7 undetected.

There is no accurate average for any leaking water main supply pipe because it depends on the type of break in the pipe, what the pipe size is and what the incoming water pressure is.

Recently we had a client with a small leak where we have 24/7 electronic water monitoring installed that is leaking on average of 45 litres per hour, so we use that as a basis for what leaking water main will cost on a Gold Coast water bill.

A water leak at 45 litres per minute is only a relatively small leak in larger pipes. It is unlikely to show up as bubbling at the ground unless it is directly under the grass in a shallow trench. Even looking at your water meter, it will not be evident unless you are testing your water use at the meter by checking for a water leak.

How much does a leak cost per litre?

We have always recommended that you test your water usage through your water meter every month. By having comparable figures, you will soon ascertain whether you have a leaking pipe.

We have always recommended that you install an AquaTrip water leak detection system after your water meter. An AquaTrip Water Leak detection system with an integrated automatic shutoff valve supplied and installed by Whywait Plumbing is a permanently installed leak detection protection system that quietly protects against leaks 24/7. It is a one time only insurance payment.

With our modern leak detection methods, it’s an easier task to locate a leak. However, unless you have an AquaTrip installed or use our 24/7 water monitoring service, you will still pay for a large amount of lost water before you become aware of the water leak.

If you think you have a water leak contact us because every litre that you lose is costing you $0.004348 for residential properties or $0.008909 for businesses on your Gold Coast water bill. If you naively feel that is inconsequential, we have just rectified a leak for a commercial business client in a 50mm underground polypipe water main that was leaking 106 kL every day, which is 106000 litres every 24 hours. This leak cost $944.354 every day.
