Building near or over a water main
If you are planning a new development, an extension to an existing property, building a garage or conservatory, you will need to consider whether there is a water main in the way.
We can provide a copy of our plans showing the location of water mains near to your house or development site.
If you are unable to alter your plans, we may agree to divert the water main. First we will assess what options are viable and advise what you should do next.
The minimum stand-off distance from a water main is three metres - for larger, deeper or critical mains this easement may increase.
