Spilltration® Emergency Spill Kit in 20 Gallon Overpack
Stop slurry, sediment, and heavy metals before they leave your site.

Smarter stormwater solutions — built for sites that can’t afford a violation.

Sediment, oil, fuel sheen, and heavy metals leave your site every time it rains. Standard filter socks handle sediment — but few handle everything heading for your drains, outfalls, and waterways.

Stormtration® is a line of field-tested, high-performance ES&P control products designed to capture sediment, oils, heavy metals, and other pollutants before they reach storm drains and discharge points—supporting compliance with NPDES, MS4, and state stormwater permit requirements across construction, industrial, utility, and municipal sites.

If your stormwater controls haven’t changed in a decade, it’s time for an upgrade.

Common Applications:

  • Perimeter Protection: Stop pollutants before they leave your site
  • Inlet & Drain Filtration: Capture sediment, oil and debris at the drain
  • Drains, Ditches & Outfalls: Control flow and filter runoff
  • Concrete Slurry Management: Capture concrete slurry before it reaches storm drains and waterways

Most filter socks stop sediment. Char21™ goes further—capturing petroleum sheen, sediment, and heavy metals including cadmium, zinc, nickel, chromium, and copper.
