ABT’s First Flush® drainage products are designed to collect and treat pollutants from sites under 100 acres. Sites where oil, greases, hydrocarbons, and metals must be captured in the first 30 minutes of rainfall, or otherwise be transported and mixed across the work area creating a more difficult treatment requirement for the next rain event.

FirstFlush is designed to collect sheet flow, transfer debris and sediment to catch basins, treat bacteria, hydrocarbons, heavy metals, and more with a combination of medias.

It is the ideal environmental system for sites that drain water across work areas, and are limited in space for retention ponds and larger structures. It is an on-site, in-place treatment system that controls run-off across the work area, isolating pollutants before they can move or be tracked across the site.
