An Environmentally Friendly Option


Filterra is similar to Bioretention in its function and application but has been optimized for high volume/flow treatment and high pollutant removal. Its small footprint allows it to be used on highly developed sites such as landscaped areas, parking lots, and streetscapes. Filterra is exceedingly adaptable and can be used alone or in combination with other BMPs.

How The Filterra® Works

Stormwater runoff enters the Filterra® system through a curb-inlet opening or pipe and flows through a specially designed filter media mixture contained in a landscaped concrete container. The filter media captures and immobilizes pollutants; those pollutants are then decomposed, volatilized, and incorporated into the biomass of the Filterra® system’s micro/macrofauna and flora. Stormwater runoff flows through the media and into an underdrain system at the bottom of the container, where the treated water is discharged.
