Sustainable Drainage Approval Body (SAB)

Page updated on: 28/01/2021

The Flood and Water Management Act 2010 (Schedule 3) establishes SABs in County Councils and requires new developments to include Sustainable Drainage Systems (SuDS) features that comply with national standards.In our capacity as a SAB we will:

  • evaluate and approve drainage applications for new developments where construction work has drainage implications, and
  • adopt and maintain surface water drainage systems according to Section 17 of Schedule 3 (FWMA). Developers will need to enter into a legal adoption agreement as a part of the consent process.
  • approve but will not adopt a drainage system in a publicly maintained road. Publicly maintained roads are those to which section 41 of the Highways Act 1980 applies.

All new developments of more than 1 dwelling house or where construction area is 100m2 or more will need to submit a SuDS application demonstrating compliance with the statutory SuDs standards for the design, construction, operation and maintenance of surface water drainage systems serving new developments.

You can submit your application as a separate application or alongside your planning application.

Construction work must not commence unless the drainage system for the work has been approved.
