A700 Frame and Filter
DOT filters are designed as a 2-stage filter with a sediment retention filtration material on lower half and storm water release in the upper half. This design addresses flooding issues while offering sediment retention efficiency in or near travel lanes. The rectangle frame is designed to cover inlet openings 36” x 55” or smaller.

High Flow filters use a combination of rock and high flow mesh to keep inlet free of debris and floatables.
