Jacobs senior vice-president Katus Watson said: “The South Treatment Plant Facility Program represents both a cross-generational investment in local Washington state communities and a commitment to preserve water quality throughout the region. 

“With our industry-leading programme management team, coupled with our planning, design and construction management resources, we’ll provide King County with an ideal mix of delivery experience to bring this important infrastructure programme to fruition.” 

Jacobs’ role will build upon its existing relationship with King County, where it has previously partnered to address water-quality challenges.  

This collaboration extends across an infrastructure portfolio that serves 18 cities, 15 local sewer utilities, and the Muckleshoot Indian Tribe. 

Last month, Jacobs was chosen by Singapore’s national water agency PUB to provide professional engineering services for the development of the Kranji Water Reclamation Plant. 

Jacobs’ responsibilities include engineering design, construction supervision, and commissioning of this plant.
