Your question
Do I need permission to connect to the public sewerage system?
Under section 106, 108 and 109 of the Water Industry Act, the owner or occupier of premises, or the owner of a private sewer, has a right to connect drains or a sewer to a public sewer. Before doing so, the owner or occupier must give a minimum of 21 days notice, and provide details of the mode and method of the proposed connection.
Please note, surface water may not be connected into the foul water sewers, neither is there a right to connect the run off from highways into the public sewerage system (although we would not unreasonably refuse). The discharge of land drainage into the public sewerage system is never permitted.
