Receiving an unexpectedly high water bill from the council can be frustrating, especially when your household water usage hasn’t changed. In many cases, the cause isn’t overuse at all, but a concealed water leak somewhere on your property.
Hidden leaks can waste thousands of litres of water every quarter, quietly driving up your costs and potentially causing damage if left unresolved.
What Is a Concealed Water Leak?
A concealed water leak is one that isn’t visible or easily detected. These leaks commonly occur:
- Under concrete slabs
- Behind internal walls
- In garden or underground pipework
Because they’re hidden, leaks like these can continue for months before being noticed, often flagged only after a high water bill or a warning from the council about unusual water meter activity.
Signs You May Have a Hidden Leak
You may have a concealed leak if you notice:
- A sudden or unexplained spike in your water bill
- Notification from the council about abnormal water usage
- The sound of running water when taps are turned off
- Damp patches, pooling water, or unusually green lawn areas
If any of these apply, early detection is crucial.
