Sustainable Drainage Systems (SuDS) & Flood Risk Assessments

Tuesday 04 June 2024

As professionals in the field of environmental management, we understand the importance of comprehensive Flood Risk Assessments (FRAs). But have we fully considered the role of Sustainable Drainage Systems (SuDS) in these assessments?

4 Reasons Why SuDS Should Be An Integral Part of FRAs

1) Mitigation of Flood Risk

  • SuDS are designed to manage rainfall close to where it falls, reducing water flow and volume of water entering drainage networks, thus lowering the risk of flooding.

2) Enhancement of Water Quality

  • SuDS incorporate natural filtration mechanisms, effectively removing pollutants from runoff and improving the quality of water that reaches our rivers and the sea.
  • Fact: SuDS can reduce sediment runoff.

3) Promotion of Biodiversity

  • SuDS features like rain gardens, swales, and attenuation basins provide habitats for wildlife, fostering biodiversity in urban environments.
  • Fact: SuDS can increase local biodiversity by providing habitat for various species of plants, insects, and birds.

4) Providing Amenity Value

  • SuDS can be integrated with other land uses, offering recreational spaces and amenities, promoting multi-functional use of urban areas.
  • Fact: SuDS can enhance property values and community well-being by providing green spaces for relaxation and recreation.(Susdrain)

Conclusion

Incorporating SuDS into FRAs not only helps us manage flood risk more effectively but also contributes to healthier, more sustainable urban environments through mitigation of flood risk, enhancement of water quality, promotion of biodiversity and providing amenity value.
