A U.S. Air Force Reserve Station in Pittsburgh, Pennsylvania was concerned that heavy metals, including lead and copper, from spent ammunition rounds was being washed by stormwater runoff into a nearby waterway. To address the risk, the U.S. Air Force hired Hillman Environmental Group, a nationwide, full-service environmental consulting firm, to recommend a passive stormwater treatment Best Management Practice (BMP) capable of removing these toxic pollutants and protecting the environment.
Staff from Hillman Environmental Group considered a multitude of options before specifying a StormwateRx Clara® 25C basic separator. The Clara was selected for its unique ability to settle particulates, including heavy metals, while preventing pollutant wash-out during large storm events. The Clara basic separator was easily retrofit to the existing firing range drainage system, reducing the capital cost of the project.
Maintenance for the Clara is another benefit for the rifle range because it is owner maintainable. The rifle range is able to use its preferred vactor service provider to perform the maintenance. All four chambers of the Clara are easily accessible by manholes.
