If you're building a new house, you are most likely going to need a new water connection to our water main and a connection to the public sewer to take sewage away.

All you need to know about getting connected to our water and waste networks.

When you need a new water or sewer connection

You will need to apply for a new connection if you, or your developers, are working on a project that involves:

  • converting a building into many homes, such as a house into flats
  • converting a barn into a home
