How it Works
A BioSTORM® Stormwater Treatment System is a best management practice (BMP) for stormwater management. Stormwater enters into the system from a curb opening, drainage network and then large trash and debris is filtered through the StormTEE® to the second cell of the BioSTORM for filtering fine sediment and hydrocarbons before exiting the system into the receiving environment; i.e. detention ponds, open source waterways, lakes, and/or water reuse holding tanks. These systems are designed to have a high (90+%) pollutant removal rate.
The pre-engineered BioSTORM®’s unique off-line design consists of a patented StormTEE® self-cleaning deflector screen and a modular separation/coalescing unit, all housed in readily-available precast concrete tanks. The versatility of the system allows components to be used separately for different applications, or together to form a complete BioSTORM® system. Various sizes are available depending on local site and environmental considerations.
How it Installs
This pre-engineered stormwater treatment system removes trash, sediment, oil and other suspended solids efficiently & effectively – more than 90% removal rate! Maintains the treatment performance regardless of hydraulic surge flows in a unique modular design to provide efficient liquid to solids and oil to water separation. The easy to install and maintain system is ideal for pre-cast concrete tanks and only requires periodic removal of debris in the trash tank(s).
Finding the Right Size
It is recommended to check what local regulations are required in case additional information is needed.
