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).

Design and Construction Guidance (formerly known as SfA8) - coming soon

Water UK has published a pre-implementation version of Design and Construction Guidance (formerly known as SfA8).  This is expected to come into effect by April 2020 as part of the sector’s implementation of the Ofwat Code on Adoption Agreements.  The ultimate power of approval for the document as part of the adoption code rests with Ofwat but when the new guidance does come into effect, it will be the only guide to the standards that sewers must meet if they are to be adoptable by water and sewer companies in England.

For the first time, guidance on adoptable SuDS has been provided.

Even if the final form of the guidance may change as part of the adoption code work, water and sewerage companies, planning authorities and developer are already considering charges to policies and procedures in order to implement the new manual.  The advance publication is intended to allow sufficient time for those changes to be made.

Pre-implementation version - Design and Construction Guidance

We will be working with customers over this period of time to provide further updates.

Note:  South West Water is currently unable to accept submissions under the Design and Construction Guidance
