Abstract

A stormwater filter assembly includes a hood and an outlet tube within the hood for draining filtered stormwater. The outlet tube has a solid wall along at least a portion of its height, and an inlet above the solid wall. A second tube is disposed about the outlet tube defining a flow space therebetween for receiving filtered stormwater. The second tube includes a wall that is perforated along at least a portion of its height that overlaps with the solid wall of the outlet tube such that filtered stormwater that enters the flow space must move upward to enter the outlet tube. A filter media is disposed between the hood and the second tube through which stormwater travels during a filtering operation.
