Concealed water leaks

How do I know if I have a water leak?

Water leaks can happen inside your property’s plumbing or underground pipework and may not always be obvious.

Signs you might have a leak include:

• A sudden increase in your water bill without a change in your household’s usage.
• Damp, wet, or unusually green patches in your garden or lawn.
• The sound of running water when all taps and appliances are turned off.
• Water stains on walls, ceilings, or floors.

You can also do a simple meter test:

1. Turn off all taps and water-using appliances in your home.
2. Check your water meter (usually near the front boundary).
3. If the dial continues to move, water is flowing somewhere on your property, which may indicate a leak.

If you have a smart water meter installed, please refer to the Smart Water Meter Read Instructions

If you suspect a leak:

• Within your property boundary (private plumbing): Contact a licensed plumber to investigate and repair.
• At or before the meter (Council’s infrastructure): Contact Cairns Regional Council to report the issue.

It’s important to act quickly, as leaks can waste large amounts of water, increase your bills, and cause property damage.

But I can't see a leak? (concealed water leaks)

Not all leaks are visible. A concealed leak happens when water escapes from underground or hidden pipework on your property, in places you can’t easily see.

Common signs include unusually high water bills, damp or soggy ground, or the sound of running water when taps are off. If you suspect a concealed leak, contact a licensed plumber to investigate.

Who covers the cost of finding and fixing a leak on my property?

Property owners are responsible for maintaining the plumbing on their side of the water meter, which includes arranging and paying for leak detection and any plumbing repairs. Under the Plumbing and Drainage Act 2018, owners must take all reasonable steps to keep their plumbing in good working order.

Council does monitor water usage and will attempt to notify customers if we detect unusual consumption that may indicate a leak.

However, it’s ultimately the owner’s responsibility to investigate and repair leaks as soon as possible to avoid higher bills and unnecessary water loss.

Residential property owners and eligible Not-for-Profit organisations can apply for financial assistance to help with the increased costs associated with a concealed water link.

You can submit an application using the Application for Financial Assistance - Concealed Water Leak form.
