The Evolution of Hydrodynamic Separators (HDSs)
Course Information
Hydrodynamic separators (HDSs) are one of the most commonly utilized treatment solutions in stormwater management, but not all HDS units function the same. This webinar will discuss the basic operating principles of HDS and how the design of these devices has evolved over time.
Participants will learn why technology design changes are occurring as well as how to properly assess the sediment removal and treatment performance of HDS units. Specific focus will be placed on the new Stormwater Testing and Evaluation of Products and Practices (STEPP) verification program and how it can be used by stormwater managers and designers to evaluate these types of treatment systems.
The STEPP program is a Center of Excellence within the National Municipal Stormwater Association (NMSA) and is launching its verification service this year.
