TrenchFormer First Flush

BMP Solution 

Pollution Problem Solver

ABT Inc’s First Flush® products are 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.

Space restricted sites: First Flush technology is perfect for sites that lack the necessary area for retention ponds and larger structures.


Stormwater Filtration

FirstFlush is the perfect solution when seeking a BMP that must handle sheet flow, control vectors, collect debris, treat bacteria, and capture hydrocarbons – all on the same site.  ABT First Flush systems utilize a variety of filtration media and fabrics. 

  • Standard Filtration “Blankets”
  • Antimicrobial Filtration Media
  • Hydrocarbon Media
