Its unique standard pre-cast concrete two manhole design allows it to help you meet the EPA goal of 80% TSS removal efficiency. The inlet manhole has a tangential mounted inlet pipe that creates a swirl flow pattern, which improves flow distribution and reduces turbulence, thus enhancing sedimentation settling. Proper sizing essentially offers a complete removal of sandy sediment. The ENV 21 “Center Withdrawal Elbow Pipe” conveys flow to the outlet manhole where floatable debris is retained by using an underflow baffle. And, as with all Environment 21 products, maintenance is a cinch with access openings to all stages and a clear view to the sump. Our Storm Water Systems ideal for unique site scenarios with other utilities.
