Sustainable drainage systems, often referred to as SuDS, is a drainage solution designed to control surface run off close to where it falls and mimic natural drainage as closely as possible. Sustainable drainage systems provide opportunities to reduce the causes and impacts of flooding; remove pollutants from urban run-off at source; and, combine water management with green space with benefits for amenity, recreation and wildlife.
