BioSTORM® Stormwater Treatment Systems

How it Works

A BioSTORM® Stormwater Treatment System is a best management practice (BMP) for stormwater management by capturing and separating litter, sediment, and hydrocarbons on the go, enabling clean water to flow.

Stormwater runoff enters into the system from a curb opening, drainage network, or any other gravity-flow method through the StormTEE® (in primary trash tank) to the second tank of the BioSTORM for further treatment and filtering of 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.

How it Installs

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.

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 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.

The BioSTORM systems are designed to have a high (90+%) pollutant removal rate. 

Finding the Right Size

It’s far more efficient and cost effective to prevent pollution than it is to try to correct problems later. By installing and maintaining simple BMPs, like the BioSTORM®, and other on site pollution prevention techniques, you can greatly reduce the potential for stormwater pollution and non-compliance fines. It is recommended to check what local regulations require.
