Stormwater management involves control of stormwater quantity and quality. Stormwater quantity management focuses on managing the volume or amount of stormwater as well as the speed of runoff resulting from various storms. Stormwater quality management focuses on the prevention of water pollution by requiring best management practices for various activities, including construction.
Municipalities and utility districts utilize best management practices, including development policies, capital projects to construct stormwater sewers, ditches, and basins, and operational practices to ensure stormwater management. The goals of these efforts are improved drainage, prevention of flood damage, and improved water quality.
