Sustainable urban drainage systems (SUDS) are drainable systems that are environmentally beneficial, causing minimal or no long-term detrimental damage.

They are designed to manage storm water locally (as close to the source as possible), to mimic natural drainage and encourage its infiltration, attenuation, and passive treatment.

Contribution to sustainable development

Drainage systems can contribute to sustainable development and improve the places and spaces where we live, work and play by balancing the different opportunities and challenges that influence urban design and the development of communities.

Surface water is managed by taking account of water quantity (flooding), water quality (pollution) and biodiversity (wildlife and plants), which are collectively referred to as Sustainable Drainage Systems.

Designed to convey surface water

SUDS can manage rainfall where it falls and is also designed to transport surface water, slow runoff before entering watercourses and provide areas to store water in natural contours where it can infiltrate the ground or evaporate.

It is considered as environmentally beneficial because it causes minimal or no long-term detrimental damage as it effectively and sustainably drains surface water, minimises pollution and manages the impact on water quality of local water bodies. SUDS may also allow new development in areas where existing sewerage systems are close to full capacity and enable development within existing urban areas.
