North King County/South Snohomish County projects
With the Treatment Plant now operating, work is focusing on the remaining components of the Brightwater project to be constructed in 2012 and 2013. Much of this work is related to completion of the conveyance system and restoration of the portal sites impacted by the last six years of construction. Planned work includes installation of 3,000 feet of lining in the west conveyance tunnel, construction of a sampling facility at Point Wells, construction of odor control facilities at Ballinger Way and North Kenmore portal sites and final restoration of all the construction sites used to complete the project. Brightwater’s 13-mile conveyance system and outfall at Point Wells began operating in November 2012.
The North Creek Interceptor Project includes completing construction of approximately 10,000 feet of new sewer line, along with connecting this new line to previously constructed pipe. This project is needed to expand the capacity of part of the County's North Creek Interceptor sewer line, to accommodate the projected growth and flows from southwestern Snohomish County. The project is in final design and is tentatively scheduled for construction starting in 2014.
