What are SuDS?
SuDS mimic natural processes and reduce flooding by managing rainfall close to its source and wherever possible at, or near the surface, as opposed to sending it down a drainpipe as quickly as possible.
By building in permeable paving, channels, green roofs, swales, soakaways or ponds, SuDS slow, store and treat water that could cause damage. Well-designed SuDS should wherever possible incorporate the four elements of water quantity, water quality, amenity and biodiversity.
SuDS can be delivered in a variety of urban and rural contexts including housing, schools, community buildings, parks, public open spaces and highways. Incorporating natural processes help make communities greener, more attractive places to live.
If constructed incorporating natural planting including trees, SuDS can deliver extensive wider benefits. These can include enhanced nature incorporation into built environments, for biodiversity, placemaking, human health and wellbeing, air quality, and urban heat island mitigation. They can also filter and provide a level of treatment to the water running into them.
