Connecting to a sewer

If you're planning to connect or reconnect to one of our sewers, you’ll need our consent before you go ahead. We need to check the connection will work as planned and that it won’t potentially cause problems like sewer flooding or pollution. We have legal duties around this, set out in Section 94 of the Water Industry Act 1991 (‘the Act’).

Sewer connections can be made directly to a public sewer or indirectly to a private drain that in turn discharges to a public sewer. Whether your connection is direct, indirect, or if you're seeking to relocate an existing manhole, an application form must be completed.

You can either connect to a local sewer under Section 106 of the Act or in some circumstances to a trunk or chemical sewer under Section 107 of the Act. Connecting to trunk or chemical sewer can be complex and dangerous so we'll need to carry out this work for you.

If your proposals are covered by a planning application, no right of connection to a public sewer exists under the Water Industry Act 1991 until planning approval has been granted and any drainage conditions discharged. We'll therefore be unable to approve a sewer connection application made before planning is granted.
