METAL RECYCLING STORMWATER

Client: A Metal Recycling Facility

Location: Seattle, WA

About the Project

A local metal recycling facility was concerned about potential recontamination of a cleanup area on the Duwamish River and opted to lower their risk horizon by implementing a stormwater runoff treatment system. Clear Creek worked with the facility’s consultant and engineer to develop a water treatment strategy that would reduce stormwater pollutants prior to discharge from the site. Based on the results of treatability testing, Clear Creek designed a 100 gpm industrial stormwater treatment system that was capable of meeting all required discharge criteria.

Clear Creek provided turnkey services including custom treatment system fabrication, construction of site improvements, installation of equipment and training of site personnel. By utilizing a team approach with a design/build contract, Clear Creek was able to reduce the project timeline from 6 months to 90 days. Since installation in 2011, the treatment system has consistently met all compliance goals.
