Approval and Adoption Procedure

Developments meeting the criteria will be required to make an application and obtain approval from the Sustainable Drainage System (SuDS) Approving Body (SAB), alongside planning permission.

The SAB is a statutory function delivered by local authorities to ensure that drainage proposals for all new developments meeting the criteria are designed and built in accordance with the national standards for sustainable drainage published by Welsh Ministers.

These Regulations set out procedures for the determination of applications by the SAB. The SAB will have 7 weeks to determine applications other than those requiring an Environmental Impact Assessment, in which case it has 12 weeks.
