Washington Iron Works, a leader in the Southern California architectural steel fabrication business, installed a state-of-the-art industrial stormwater treatment system by StormwateRx. The water quality protection system removes sediment, oil, and heavy metals that could impair waterways of the Los Angeles drainage basin.
Washington Iron Works undertook the project voluntarily and upon their own initiative to demonstrate the company’s commitment to the community and protection of the environment. The project also assists the facility in demonstrating progress toward the stormwater benchmarks established in their industrial stormwater general permit by the California State Water Resources Control Board.
The StormwateRx stormwater treatment system includes a passive Clara 90C plug flow separator installed in-line with the existing stormwater drainage lines for the reduction of particulates. The Clara then feeds into an above-ground Aquip 160SXI stormwater filtration system, which contains inert media for the reduction of finer particulates (TSS) and associated total heavy metals. Engineers designed the stormwater management system to collect stormwater runoff from around the facility, routing it to a main outfall where the StormwateRx stormwater treatment and reclamation systems are installed.
As a result of this installation, Washington Iron was able to reduce all parameters to below benchmark standards except zinc. If a higher level of zinc removal is desired, the Aquip system can be upgraded during a maintenance cycle to the model SBE, which has a buffering pretreatment media and a combination of inert/sorptive filtration media for enhanced metals removal.
These third-party results are from samples taken during a December 2008 rainfall event, nearly a year after the system was installed.
