Oldcastle Infrastructure biofilter bests water pollution control metrics

Atlanta-based Oldcastle Infrastructure has secured Virginia Department of Environmental Quality approval for the BioPod Biofilter System with StormMix Media, recognized for 50 percent total phosphorus removal efficiency—the highest available rating. The agency nod turned on Oldcastle Infrastructure field data plus General Use Level Designation from the state of Washington.

Oldcastle Infrastructure has evolved its stormwater management solutions portfolio with BioPod and companion technologies as state and local government agencies take a harder look at best pollution control practices.

“Now that the BioPod has received approval, designers in Virginia will have a state-of-the-art, engineered, high-flow rate bioretention option for stormwater treatment and green infrastructure solutions,” says Oldcastle Infrastructure Regulatory Engineer Joanna Ogintz.

BioPod systems utilize an advanced design for filtration, sorption and biological uptake to remove total suspended solids, dissolved metals, nutrients, gross solids, trash and debris as well as petroleum hydrocarbons from stormwater runoff. StormMix media, an engineered high-flow rate material, removes stormwater pollutants. Oldcastle Infrastructure offers an optional, integrated high-flow bypass that eliminates the need for a separate bypass structure, reducing costs and simplifying the design.

BioPod affords municipal or private drainage infrastructure officials design and construction flexibility, and is packaged as an all-in-one, single-piece unit composed of durable precast concrete for ease of installation and long service life. It is set for listing on the Virginia Best Management Practices Clearinghouse site, www.swbmp.vwrrc.vt.edu.
