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. Construction began in early 2006 and was completed in 2012.
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.
This project was also the first project in the Brightwater Conveyance System group to be completed on time, within budget and without any claims or issues. Christie True, Wastewater Treatment Division Director for King County, commended us for our quality of work and our cooperative attitude toward the project and the owner at a public ribbon cutting ceremony celebrating the completion of this phase of the Brightwater project.
