The V2B1 Stormwater Treatment System provides primary treatment of stormwater using a two stage treatment process. In stage one, a tangential inlet pipe produces a vortex within the manhole to utilize centrifugal forces to "spin" the suspended solids out of suspension.

The surface water then travels through the center pipe to the second chamber where the floatable debris and hydrocarbons are trapped. The seperation is accomplished using a precast baffle wall which is engineered for each specific application to maximize effieiency.

The V2B1 Stormwater Treatment System is sized to help achieve the EPA goal of 80% TSS and 40% Phosphorus removal efficiency. In addition to a standard online system, the V2B1 can also be configured with an internal high flow bypass.

The system can be configured to bypass the swirl chamber or both the swirl and floatables chambers. This flexibility allows the design engineer to decrease the size of the required V2B1 system, thereby decreasing construction costs.

All V2B1 Stormwater Treatment Systems are manufactured by Con Cast Pipe.

We are an approved manu- facturer of the V2B1 system with a proven record of quality in the precast concrete market. Our high level quality standard includes the OCPA administered Plant Prequalification Program and CSA A257 Certification.

V2B1 Service Features and Maintenance

Every Environment 21 system is designed site specific providing optimal performance for your project. With every system design you will receive a Site Layout, Design Storm Hydrology, Water Quality Hydrology, Back Water Analysis and a System Specific drawing.

In addition, we will provide you with an estimated clean out and inspection interval specific to your site and system. The shallow sump of the V2B1 allows the use of standard vacuum truck for maintenance. The unique vertical insert design of the V2B1 with two access openings per chamber allows for clear access to all areas of the chamber for inspection and maintenance.

By combining continuous field and laboratory testing with ongoing realistic case studies, we are able to provide you the confidence that you are meeting your local , provincial, and national stormwater management requirements. Environment 21 engineers work directly with you to reduce system costs while optimizing treatment efficiency.
