There’s a Leak Under the Pavement — What Can I Actually Do?

If you can see water appearing under the pavement outside your property, it’s natural to assume there’s a leak — but it’s often unclear what you’re actually allowed to do about it.

This situation creates confusion because the problem is visible, yet the location sits outside your direct control. Understanding what’s happening — and what your next step should be — is key.

Can a Leak Occur Under the Pavement?

Yes, leaks can occur beneath pavements and external ground areas. These may come from different parts of the water system, including the public network or pipework connected to your property.

Depending on the exact location, the leak could be coming from:

  • The water main (public supply)
  • The communication pipe (leading to the property boundary)
  • The supply pipe (running from the boundary into your property)

This is why the visible location of the water doesn’t always tell you who is responsible.

Why the Location Causes Confusion

Many homeowners assume that if a leak appears under the pavement, it must belong to the water company. In reality, responsibility is based on where the pipe sits in relation to the property boundary — not just where the water is visible.

This means a leak can still relate to your supply pipe even if it appears outside your home.

What You Can’t Do

If the leak is under a public pavement or road, you cannot access or repair it yourself.

This includes:

  • Digging up the pavement
  • Accessing pipework in public areas
  • Attempting to expose the source of the leak

These areas are controlled by the water supplier and local authorities, and any work must be carried out through the correct channels.

What You Should Do First

If you suspect a leak under the pavement, the first step is to contact your water supplier. They will check whether the issue sits on their side of the network.

This allows them to confirm whether the leak is coming from:

  • The public main
  • The connection up to your property boundary
  • Or somewhere beyond that point

In many cases, they will inspect the area and determine whether it falls within their responsibility.

What Happens If It’s Not on the Network Side

If the water supplier confirms the issue is not on their side, the focus shifts to the supply pipe connected to your property.

At this stage, the exact location of the leak needs to be confirmed before any repair work can be planned. Without this, unnecessary disruption can occur.

You can see how this is handled in what happens after a mains water leak is found.
