The “V2B1” is the flagship of environment 21. 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 environment 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. The V2B1 is ideal for unique site scenarios with other utilities.

The NYSDOT is currently reviewing, revising, and eventually issuing the new SWTD Specification, §738-01. The Environment 21 StormPro was reviewed by the NYSDOT and conditionally approved pending issuance of the new SWTD Specification. In the interim, the StormPro may be used on NYSDOT projects after standard review by the NYSDOT office nearest to the proposed project.
