Renovating or extending a house

If you are planning to renovate or add an extension to an existing property then we are here to help.

Before you start, check if your development is in our area.

There could be existing sewers or water mains running near the property that may be impacted by your project. If that's the case, then we'll need to discuss this with you.

You can get a copy of our network maps via our free online service.

Please take care to read the disclaimer on the map.

We recommend that a comprehensive survey is undertaken in addition to reviewing this map to determine the existence and precise location of any of our apparatus.

If you are new to building and developing then don't worry, we are here to help. You can contact us and we will be happy to review your specific circumstances and explain what you need to do.
