We (STS) do not take on SUDS as part of Aquatrine, Sewers for Adoption is a technical standard, designed for developers looking to Statutory Undertakers (SUs) to adopt said assets. STSD is not an SU and whilst we may be comfortable with MOD and MOD developers building to SFA, this does not include SUDS. We do not adopt geo-cellular type of attenuation or soakaways, we can provide the type of structures we would accept but you would need to submit your proposals in the first instance to comment on.
