Hydrodynamic separators (HDS) are stormwater management devices used to control water pollution. They are designed as flow-through structures with a settling or separation unit to remove sediment and other pollutants. HDS are considered structural best management practices (BMPs), and are used to treat and pre-treat stormwater runoff.
