BakerCorp Completes Innovative Water Treatment Project at Superfund Site

Successful treatment of more than 63 million gallons of water despite challenging circumstances

After 100 years of industrial and urban use, a specific section of the Duwamish River in Washington State had experienced nearly a dozen incidents involving sewer or storm water overflows. As a result, this environmental remediation project required a site-specific solution. Acting as the project’s onsite single-source vendor, BakerCorp developed, engineered and managed a complete solution, utilizing filtration systems, tanks, pumps and all necessary equipment.


Working in conjunction with the City of Seattle, Port of Seattle, King County, and a large aerospace manufacturer in the Northwest, the project was overseen by the Washington State Department of Ecology and the U.S. Environmental Protection Agency. Strict limitations on returning treated water to the river forbade the use of any chemical solutions.


Despite several previous unsuccessful water treatment attempts by others, BakerCorp designed a process that could adapt to changing water conditions. Conducted in the midst of a still active water source, the Duwamish River project included contaminants and water volumes that varied significantly during the project. Yet, the team of onsite personnel adjusted the process according to the circumstances and maintained a steady pace for processing water flow. Under such conditions, the system maintained a continuous treatment process with a flow rate up to 900 gallons per minute (GPM).


The Duwamish River project was ultimately one of BakerCorp’s largest and most complex projects. But by leveraging all of the tools and expertise available in BakerCorp, the team was able to find an efficient and cost-effective solution that will make the Duwamish River a safe and beneficial resource for future generations.
