Adoption of new sewers or pumping stations

Banner image

We promote the use of a Section 104 agreement (Water Industry Act 1991) for the adoption of sewers and waste water pumping stations that are to be built as part of a new development.  Sewers and pumping stations must be built in accordance with the current publication of Sewers for Adoption (SFA)*.  As part of this application, you’ll also need to apply for a Sewer Connection (under Section 106 of the Water Industry Act 1991), if you wish to communicate to our existing asset - please click here for more information.

If you have already constructed your sewers and they are receiving flows, adoption can be carried out under Section 102 of the Water Industry Act: adoption of existing sewers - please click here for more information.

To enable a successful installation of the sewers, we are keen to start inspections as soon as possible after construction commences.  If we have not been in contact with to arrange a convenient site meeting to start the inspection process, please contact the Developer Services Sewer Adoption Team.

* (Currently 7th edition, although applications under 6th edition are still permissible, although 6th and 7th standards cannot be mixed).
