Stormwater Drain Filter System

  • PolyDrain FirstFlush®

    Stormwater Filtration for Urban Runoff

    The "first flush effect" refers to the initial surface runoff during a rainstorm and the resulting surge of concentrated water pollution. Corresponding high sheet flows wash the pollutants through storm sewers to local surface waters. Our engineers created a Best Management Practice (BMP) to counter the negative effects of urban runoff.

    Any storm runoff filtration system will collect debris, capture hydrocarbons, and should reduce pollutants. Our PolyDrain stormwater filtration solution also manages the significant overland flow during initial runoff events. We prioritize the stormwater first flush treatment event by allowing prolonged rainfall to bypass the treatment media. This bypass minimizes pulsing and prevents concentrated pollutants from the "first flush effect" from continuing on to downstream waterways.

    FirstFlush® is the perfect sustainable drainage solution to meet this critical stormwater filtration challenge.

  • TrenchFormer FirstFlush®

    Stormwater Filtration for Urban Runoff

    The "first flush effect" refers to the initial surface runoff during a rainstorm and the resulting surge of concentrated water pollution. Corresponding high sheet flows wash the pollutants through storm sewers to local surface waters. Our engineers created a Best Management Practice (BMP) to counter the negative effects of urban runoff.

    Any cast-in-place stormwater filtration system will collect debris, capture hydrocarbons, and should reduce pollutants. Our cast-in-place stormwater sustainable drainage and filtration products and solutions also manage the significant overland flow during initial runoff events. We prioritize the treatment of a first flush event by allowing prolonged rainfall to bypass the treatment media. This bypass minimizes pulsing and prevents concentrated pollutants from the "first flush effect" from continuing on to downstream waterways.

    FirstFlush® is the perfect solution to meet this critical stormwater filtration challenge.

  • Oil-Water Separator

    Gravimetric Pre-Treatment Tank

    TrenchFormer is uniquely positioned to collect non-point source (NPS) pollution from urban runoff. Our cast-in-place trench drain Oil-Water Separator is a cost-effective addition that separates these urban pollutants into their discrete components. Using a baffle plate, stand-pipe assembly, and gravity, our system separates oil, water, and solid particles from the site’s wastewater.

    Uniquely, the TrenchFormer concrete Oil-Water Separator tank is constructed using a lightweight cast-in-place forming system that installs without the necessity of heavy equipment. The basic system contains no moving parts. Periodic removal of captured oil and solids is the only maintenance required.
