Water UK has published a pre-implementation version of Sewers for Adoption 8 (SfA8). This is expected to come into effect by mid-2019 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 sewerage companies in England.
For the first time, guidance on adoptable SuDS has been provided.
The work to develop the manual was led by a steering group chaired by Professor David Balmforth. This included representatives from a broad range of parties with an interest in or likely to be affected by SuDS adoption by the water and sewerage companies.
In addition to water and sewerage companies, members of the group included Defra, EA, CIRIA, LPAs, LLFAs, specialist drainage engineers and SuDS consultants as well as developers.
Even if the final form of the guidance may change as part of the adoption code work, water and sewerage companies, planning authorities and developers are already considering changes to policies and procedures in order to implement the new manual. This advance publication is intended to allow sufficient time for those changes to be made.
We have also prepared a non-technical guide to the new approach which explains how it applies in practice. The guide contains illustrations of potentially adoptable SuDS assets and is available here”
