Hydrodynamic separators (HDS) are stormwater management devices that use cyclonic separation to control water pollution. They are designed as flow-through structures with a settling or separation unit to remove sediment and other pollutants.[1] HDS are considered structural best management practices (BMPs), and are used to treat and pre-treat stormwater runoff.

Protecting Lake Lewisville Rural Texas contains a number of what are termed “farm to market” roads, or “FM” for short. FM 720 is one of those roads, located in Denton County, just northeast of Ft. Worth. The Texas Department of Transportation (TxDOT) is in the process of upgrading the roadway

Separation Devices for Stormwater Runoff

Separation Devices for Stormwater Runoff

National Pollutant Discharge Elimination System (NPDES) Phase II requires control of runoff from sites both during construction and after construction. Post-construction runoff control usually involves more permanent (and more expensive) devices than the temporary berms, silt fence, and other materials used during active construction. These permanent devices fall into two

BMP Testing Protocols

After Wisconsin passed new administrative rules for the prevention and management of polluted stormwater runoff in 2002, a chain reaction ensued. The implications: a requirement for 80% total suspended solids (TSS) removal in new development and 40% TSS removal in redevelopment areas; in existing urban areas, 20% by 2008 and
