The “UniStorm” is environment 21’s system which employs low head loss internal flow diffusers and flow distributors. This design reduces turbulence, improves flow distribution, and allows on-line operation to eliminate pollutant bypass during high intensity rainfall events. The UniStorm is available in manholes and vaults , and it carries the environment 21 reputation for helping meet EPA regulations of 80% TSS, but the cost savings obtained from using a single structure design. In addition the UniStorm can be designed with a flow control device when it is being utilized at the outlet of detention, creating the perfect treatment train.
