Summary of decision

The Cabinet Member for City Management and Air Quality has approved the adoption of the Sustainable Drainage System (SuDS) Design Manual which is to be used by the Council and our contractors when developing, designing and constructing SuDS across Westminster’s public realm.  

Reasons for decision

 

Sustainable drainage systems (SuDS) are drainage solutions that provide an alternative to the direct channelling of surface water through networks of pipes and sewers to nearby watercourses. They reduce the risk of flooding and pollution from urban water runoff. They can improve water quality, increase biodiversity, and enhance the amenity of an area. The SuDS Design Manual is an important step to rolling out SuDS at pace across the city. Standardised design guidance ensures any SuDS going in the ground are high quality and are built to last. Shared design commonalities across SuDS increases cost efficiencies in construction and maintenance of schemes.
