LITTLETON, Colo. — Oldcastle Stormwater Solutions’ Perk Filter™, a stormwater media filtration device used to reduce pollutant loading in runoff from urban developments, received approval for use to meet the new water quality design requirements of the Virginia Stormwater Management Program by the Virginia Department of Environmental Quality (DEQ), according to a press release.
After comprehensive review the filtration device received a total phosphorous removal efficiency of 50 percent, required by the DEQ, and has been added to Virginia Stormwater BMP Clearinghouse website as an approved filter device, stated the release.
The release reported that in addition to the DEQ approval, the Perk Filter has a general use level designation (GULD) from the Washington Department of Ecology for both basic treatment and phosphorous treatment, requiring as a minimum 80 percent total suspended solids removal.
"The approval of Perk Filter by the [Virginia] DEQ sets a milestone in the ongoing battle to improve water quality in the Chesapeake Bay Region and gives the civil engineering community a solid third party, independently verified option for stormwater management issues,” said Oldcastle Stormwater Solutions Director of Business Development Laddie Fromelius. “We are looking forward to the opportunity of providing this solution to our clients from our local manufacturing plant in Fredericksburg, Virginia."
