Storm water drainage filter assembly

Abstract

A filter assembly is mounted on the discharge end of an outlet pipe of a storm water drainage system for filtering and collecting silt, dirt and other debris from runoff water flows. The filter assembly includes a collar member mounted within the discharge end of the outlet pipe and a filter bag that is removably attached to a downstream end of the collar member. The water flow being discharged from the outlet pipe of the storm water drainage system is channeled through the filter bag, which filters and collects the sediment and debris therefrom while enabling the substantially cleaned runoff water to pass through the filter bag for drainage into a stream, pond, or other water source.
