Stormwater Management
Controlling rainfall runoff in built environments to prevent flooding, pollution and aquifer depletion.
Definition
Stormwater management is the planning and engineering of rainfall runoff in urban areas: collecting, conveying, treating and infiltrating water that falls on roofs, roads and pavements. Conventional design pipes water away rapidly, causing flash floods, combined sewer overflows and polluted discharges; modern practice — sustainable drainage systems (SuDS), low-impact development, green infrastructure — slows, stores, cleans and infiltrates runoff close to where it falls.
