In response to growth in the region, King County built a new wastewater treatment system, the Brightwater Conveyance System, to serve north King and south Snohomish counties. Brightwater construction occurred at five sites: the treatment plant site in Snohomish County near Woodinville; and four portal sites in Bothell, Shoreline, Kenmore, and unincorporated Snohomish County.

The work under this contract involved construction of the North Creek Connector, a 72-inch sewer and the associated diversion, drop, and flow monitoring structures; reuse water facilities connecting the Brightwater North Creek Portal and North Creek Pump Station with 2,350 feet of 30-inch restrained joint ductile iron reuse water main; North Creek Pump Station modifications; and construction of odor control facilities including a packaged bio-filter, foul air piping, screen wall structure and the associated mechanical and control installations.
