ecoStorm is designed to separate floating pollutants, debris and contaminated settling solids from stormwater drainage. Also designed for non-point source pollutant removal upstream of holding ponds, the system greatly reduces pond pollutant levels and frequency of pond maintenance. It is a cost-effective best management practice for meeting pollutant removal regulations in a variety of industrial, commercial and residential applications.

The patented First Flush Valve for Stormwater Metering, available from Red Valve, is designed to control the “first flush” of a rainstorm. The bottom portion of the FFV has a mouth type opening which permits low flow under normal conditions, as well as functioning as a clean-out port for accumulation on the bottom of the line. The second zone is designed as a holding area for the heavy “first flush” downpour, while the stormwater line serves as a storage tank.

The Cyclone from CDS Technologies is a self-cleaning CSO screen designed to be virtually maintenance free. The stainless steel screen requires no mechanical cleaning of the screen surface and no external power source, as it operates by using the available energy of the overflow through an internal water wheel. With numerous installations throughout the UK and US, the screen has a track record for reliable combined sewer overflow screening in municipal settings.
