The King County Wastewater Treatment Division is planning more than $800 million in infrastructure improvements at its South Treatment Plant in Renton, Washington. The county recently selected Jacobs to provide consulting and program management services that support the work, the company announced July 2.
The South Treatment Plant is one of five wastewater plants in King County, which includes the city of Seattle. The plant began operating in 1965 and treats an average of 90 million gallons of wastewater per day, according to WTD.
WTD has a list of about 30 capital improvement projects planned for the South Treatment Plant, including seismic upgrades to the influent pumping station, rehabilitation of dissolved air flotation thickener tanks, upgrades to dewatering carbon cleaning, replacement of raw sewage pumps and electrical upgrades. The $13 million contract with Jacobs would cover up to 12 years.
The plant’s infrastructure program “represents both an intergenerational investment in local Washington state communities and a commitment to preserving water quality throughout the region,” said Katus Watson, Jacobs senior vice president , in a statement.
This has been the county’s regional treatment system’s most productive five years for improvements since it was built in the 1960s, with dozens of capital projects, according to WTD. The division plans to invest more than $10 billion over the next decade in maintaining and repairing aging assets and building new infrastructure in preparation for climate change.
In March, the U.S. Environmental Protection Agency announced that it had committed to providing WTD with a $498.3 million Infrastructure Innovation and Financing Act low-interest loan package water to help fund 14 infrastructure projects focused on improving water quality, including the South Treatment Plant Influent. pumping station seismic improvements. The project aims to protect the plant from major seismic events.
Jacobs has previously provided water quality-related infrastructure services for King County on projects such as the Georgetown Wet Weather Treatment Plant and the Brightwater Water Treatment Plant. The company is also currently the design engineer for a progressive design-build project rehabilitating sections of the Eastside Interceptor wastewater pipeline in Bellevue, Wash.
