ASTM Eyes Catch Basin Filters Standard

A proposed ASTM International standard will offer a means to reduce the impact of contaminated stormwater entering local drains. WK45326, Specification for Stormwater Catch Basin Filter, will aid community developments, sports facilities, fairgrounds, stadiums and factories in complying with U.S. Environmental Protection Agency clean water initiatives.

“Inlet protection has become part of every stormwater pollution prevention plan,” says Advanced Drainage Systems National Engineering and Applications Manager Jonathan Sickels. “When these measures are not implemented properly, this can lead to job site flooding, erosion and hazardous road conditions. Additionally, when various inlet protection devices become clogged, disturbed soils and construction site pollutants can run toward neighboring storm drains, ponds, lakes and rivers.”

ASTM WK45326 describes a fully sustainable framing system for high efficiency geotextile sediment bags used as a structural best management practice for stormwater inlet protection. The replaceable geotextile bag provides a flow rating of 200 gallons per minute per square foot of material and retains a minimum of 80 percent of construction site runoff, including clay, silt, sand and gravel.

ASTM WK45326 is being developed by Subcommittee D35.03 on Permeability and Filtration, part of ASTM Committee D35 on Geosynthetics, whose next meeting is January 28-30 in New Orleans.
