Sustainable Drainage Systems (SuDS)

As urban development expands, the risk of surface water flooding increases. Sustainable drainage systems (SuDS) are designed to control surface water close to where it falls and mimic natural drainage as closely as possible. There are several types of SuDS which work to manage the risk of flooding, whilst providing additional benefits for people and the environment.


Sustainable drainage systems, or ‘SuDS’, aim to manage surface water locally and are a natural alternative to traditional drainage networks like pipes and sewers. SuDS provide opportunities to:

  • Reduce the causes and impacts of surface water flooding.
  • Remove pollutants from urban runoff at source.
  • Combine surface water management with benefits for green space, recreation, wildlife and amenity.
