Urban drainage is moving away from the conventional thinking of designing for flooding, to balancing the impact of urban drainage on flood control, quality management and amenity. Surface water drainage methods that take account of quantity, quality and amenity issues are collectively referred to as Sustainable Drainage Systems (SUDS). These systems are more sustainable than conventional drainage methods because they:

  • Manage runoff flowrates, reducing the impact of urbanisation on flooding
  • Protect or enhance water quality
  • Are sympathetic to the environmental setting and the needs of the local community
  • Provide a habitat for wildlife in urban watercourses
  • Encourage natural groundwater recharge (where appropriate).

They do this by dealing with runoff close to where the rain falls, managing potential pollution at its source and protecting water resources from point pollution.

What are the advantages?

SUDS allow new development in areas where existing sewerage systems are close to full capacity, thereby enabling development within existing urban areas. SUDS also treat pollution at source and provide effective attenuation, thereby satisfying the Environment Agency's requirements for discharging into watercourses. Another significant advantage of SUDS is that it can be a cost effective method of providing drainage solutions in contaminated land.
