Jacobs was selected to provide program management and consultancy services to support the delivery of more than $800 million in critical infrastructure upgrades for King County Wastewater Treatment Division. Improvements will enhance water quality and system resiliency for approximately two million people in Seattle and across the central Puget Sound region. Leveraging experience from similar complex infrastructure programs, Jacobs will provide oversight from initiation through design, construction and commissioning for the South Treatment Plant Facility Program.

Located in Renton, South Treatment Plant is one of King County's three regional wastewater plants. It treats an average of 115 million gallons of wastewater per day during wet weather and 96 million gallons per day during dry weather. The facility also hosts on-site educational programming and features a 1.5-acre demonstration farm, CitySoil, that produces approximately 4,000 pounds of food annually for a local foodbank.

Jacobs' selection builds on a strong relationship and history of partnering with King County to tackle pressing water quality challenges across its infrastructure portfolio, inclusive of 18 cities, 15 local sewer utilities and the Muckleshoot Indian Tribe. In addition to providing program management and consultancy services, Jacobs is also serving as the design engineer for one of the county's first Progressive Design-Build projects which will rehabilitate key sections of the Eastside Interceptor, a major wastewater conveyance pipeline in Bellevue. In 2022, a Jacobs-led team completed the award-winning Georgetown Wet Weather Treatment Station, and a decade ago, Jacobs served as the prime consultant for the Brightwater Treatment Plant, which at the time it was built, was the largest membrane bioreactor in North America.
