Sustainable Urban Drainage Systems (SUDs)

Sustainable drainage systems aim to reduce the amount of runoff from a site. Key to this is to slow the flow of water, to allow it to infiltrate into the ground. Living roofs, soakaways, rills and permeable surfaces are all important for this and so are cornerstones of SuDS drainage.

Planning Authorities and the national environmental agencies are increasingly asking developers to show how they’ll manage surface water for their development in the form of a surface water drainage system or a sustainable drainage strategy (SuDS).
