Building and Developing

There are several reasons you may want to replace an existing water supply, including:

• splitting from a shared supply
• replacing lead pipes
• increased demand.

You can only replace your existing water supply pipes if the property:

• is occupied
  
• has an existing, active water account
• is not undergoing a change of use
• is not undergoing renovation by a developer who is selling it.

If you want to replace your water pipes, you are responsible for installing the private pipework.

You will need to lay a new 25mm pipe, leading from the home to the property boundary.

We will connect that private pipework to the same water main as the existing supply, using a 25mm pipe.

You can apply to the lead replacement scheme to arrange a replacement of existing lead pipes.

You can apply to the shared supply separation scheme if you want to leave a shared supply.  

You must apply for a replacement sewer connection if you are:

• making changes to our existing sewer connection
• changing sewer flows
• using an existing connection.

You can't connect to a public sewer without our approval.
