Sustainable Drainage

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. These SuDS systems and components can help prevent flooding and reduce pollution entering rivers and streams during storms.

All new housing applications (for more than one dwelling) in Wales need to incorporate Sustainable Drainage within their design that must be be approved by a SuDS Approval Board.
