Storm Water Filtration

  • 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 filtration system will collect debris, capture hydrocarbons, and should reduce pollutants. Our solution also manages 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 Oil-Water Separator is a cost-effective addition to separate these urban pollutants into their discrete components. Employing the natural force of gravity, baffle plate, and stand-pipe assembly the system separates the oil, water, and solid particles in the waste stream.

    Uniquely, the TrenchFormer Oil-Water Separator is constructed using a light-weight 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 in the only maintenance required.
