It was originally envisaged that under Schedule 3 of the Flood and Water Management Act 2010, Lead Local Flood Authorities (LLFA), such as Wiltshire Council, would be required to establish SuDS Approval Bodies. This would have required us to approve, adopt and maintain SuDS features in new developments. However, in December 2014, the Government issued a ministerial statement on SuDS announcing that Schedule 3 would not be enacted, and instead SuDS would be dealt with by strengthening existing planning policy. Therefore, as LLFA, we have no obligation to adopt SuDS.

Currently, we may adopt SuDS for road drainage as part of road adoptions under Section 38 of the Highways Act 1980. We do this in our capacity as Highway Authority. However at this stage, we do not adopt SuDS for property drainage as an LLFA.

To find out more about the processes required to secure road adoption, contact us at HighwaysDevelopment@wiltshire.gov.uk.


Besides the Land Drainage Act requirement we have its own byelaws which mirror those used by the Environment Agency.

You can find copy of the land drainage byelaws in the download section.

If you have any questions or concerns regarding works adjacent or within a watercourse, contact drainage@wiltshire.gov.uk

You can find the forms in the download section for developers.
