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.

SuDS provide a natural approach to managing drainage, mimicking nature by managing rainfall close to where it falls. They are designed to drain surface water efficiently and sustainably, while minimising pollution and managing the impact on water quality provided by local water bodies.

 

Furthermore, SuDS protect and enhance the local environment, helping to improve the biodiversity and environmental aesthetic of surrounding areas.

 

How do SuDS work?

 

SuDS work by slowing down and holding back water that is running through an urban area. As surface water flows through the systems, pollutants are removed and the flow of surface water is controlled.

 

What are the benefits of SuDS?

 

SuDS have a range of key benefits:

 

  • To reduce water pollution
  • To slow down surface water run-off and reduce the risk of flooding
  • To create green space for communities and habitats for wildlife in urban areas.

 

Moreover, SuDS techniques are not considered to be any more expensive than traditional drainage options when included in the design of a new development.
