Sustainable Drainage Systems (SuDS)

With increased urban development, the risk of surface water flooding is also increasing. 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 many different types of SuDS which can not only reduce the risk of flooding, but also deliver many other benefits for people and the environment 

Introduction

Sustainable drainage systems, or ‘SuDS’, are designed to control surface water close to where it falls and mimic natural drainage as closely as possible. 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. 

Some good examples of SuDS can be seen in this United Utilities video below of the sustainable drainage garden displayed at the RHS Tatton Flower Show. Find out more about the different types of SuDS in the following sections.
