This project is anticipated to be implemented using the General Contractor/Construction Manager (GC/CM) collaborative delivery approach, pending CPARB-PRC approval. Estimated cost is approximately $22.8M. 

West Duwamish Wet Weather Storage (ITB): The West Duwamish CSO Storage Tank is a 1.25 million gallon buried cast-in-place concrete combined sewage storage tank that includes drain pumps, tipping buckets, and associated mechanical piping. Deep soil mixing is located underneath the tank and adjacent conveyance structures.

A brief description of the projects WTD will be discussing at this Open House are:

South Interceptor Rehabilitation (PDB): This project will rehabilitate 1,623 linear feet of the South Interceptor and associated structures, located in the City of Renton. Rehabilitation of 445 linear feet (LF) of 72-inch and 1,185 LF of 90-inch diameter reinforced concrete pipe, rehabilitation of up to (7) maintenance holes, modifications to the junction structure at the South Interceptor and Eastside Interceptor (located at South Treatment Plant), which may be necessary to isolate flows during rehabilitation, and the design, installation and operation of sewer diversion pumping system (including all traffic control and restoration activities). Estimated contract cost is $36M.

Black Diamond Trunk Capacity Upgrade (GC/CM): This project will add conveyance capacity to accommodate population growth over time in a manner that meets King County’s commitments to provide conveyance services to the City of Black Diamond. The scope includes upsizing approximately 6 miles of 10-inch to 16-inch sewer pipe and associated appurtenances. This project is anticipated to be implemented using the General Contractor/Construction Manager (GC/CM) collaborative delivery approach. Total estimated contract cost is $75M.

Sammamish Plateau Diversion (GC/CM): This project will address regional conveyance system capacity needs by diverting flows out of the South Lake Sammamish Planning Area north. Diverting flows northward will alleviate capacity needs at several King County conveyance facilities. Estimated contract cost is $52.4M.

Mouth of Duwamish Combined Sewer Overflow (MDCSO) Wet Weather Facilities: The County's Wastewater Treatment Division (WTD) will programmatically deliver essential infrastructure to control wet weather sewer overflows in the Duwamish River. Driven by a consent decree with a 2034 deadline, the program scope involves building sewer diversion structures, influent and effluent conveyance, a new outfall, storage tank, system integration and SCADA, and treatment facilities that include an equalization basin, screens/compactor, pump station, solids removal, disinfection, solids storage, and odor control. With an emphasis on minimizing risks and avoiding delays, the project requires high engagement with interested parties and a coordinated management of multiple projects to deliver required benefits. The program is presently conducting an Alternatives Evaluation to identify the Best Apparent System Alternative (BASA). At this online open house, the County will provide an overview of work occurring to prepare for contracting delivery of MDCSO facilities including determining type of delivery and packaging of program elements.
