Performance Enhancing Devices for Stormwater Best Management Practices

Dave Hirschman in a well put together white paper describes the role that a variety of PED technologies can have on BMP performance. Opti has been included in the document under Section 7. BMP Configuration: Internal Water Storage (IWS), Storage and Sizing:

"A more recent innovation is the use of adaptive controls to optimize storage and hydrologic functions (Opti 2015). This relatively simple technology makes use of sensors and internet weather predictions to open or restrict outlet controls, such as pond outlet structures, bioretention underdrains, and rainwater harvesting system drains. This system does not change anything about design standards, but uses the technology to substantially increase runoff capture and residence time.  

Despite any other configuration and media amendment, runoff reduction remains perhaps the most important BMP process and can account for a large fraction of overall removal for both particulate and dissolved constituents. It may be that enhanced sizing (as per Olszewski and Davis) or the Opti adaptive control system can further capitalize on this function."
