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.
