BMP SOLUTION

POLLUTION PROBLEM SOLVER

ABT Inc’s TrenchFormer FirstFlush® system is a cast-in-place stormwater channel that is designed specifically for sites under 100 acres where specific pollutants – oils, greases, and other hydrocarbons – must be captured without impeding bypass flow particularly during the first fifteen minutes of a rainfall or “first flush” effect.

Cast-in-place forming systems allow for greater flexibility for all your heavy-duty and high-volume applications including highways, airports, and anywhere you need quick and efficient drainage. FirstFlush® technology is perfect for sites that lack the necessary area for retention ponds and larger structures.

STORMWATER FILTRATION

FILTRATION MEDIA

FirstFlush® is the perfect solution when seeking a best management practice (BMP) that must handle sheet flow, control vectors, collect debris, treat bacteria, and capture hydrocarbons – all on the same site.  The ABT FirstFlush® cast-in-place stormwater channels utilize a variety of filtration media and fabrics.

  • Standard Filtration “Blankets”
  • Antimicrobial Filtration Media
  • Hydrocarbon Media
  • HMR – Heavy Metals Removal Media
