Boeing Everett Stormwater Treatment System Replacement
Delivering critical stormwater improvements across Boeing’s 700-acre facility
IMCO was contracted by The Boeing Company to replace the Everett manufacturing facility’s primary stormwater treatment system in response to updated Department of Ecology discharge standards requiring a higher level of treatment prior to releasing water into the adjacent waterway.
IMCO collaborated with the design firm to provide preconstruction services and support design development from 30 to 100 percent completion. Construction scope included mass excavation of the existing facility, steep-slope stabilization, reconfiguration of storm piping serving the 700-acre Boeing site, and reconstruction of the filter system along with the underdrain and disbursement piping.
