The Hanford Site’s Effluent Treatment Facility (ETF) has been expanded and will be able to handle almost 7 million more gallons of wastewater per year once the site’s Waste Treatment and Immobilization Plant (WTP) begins treating waste from large underground tanks.

Basin added to support Hanford’s tank waste treatment

Work is nearing completion on a fourth basin needed to ensure adequate storage for wastewater during tank waste treatment on the Department of Energy’s Hanford Site, in Washington state.

According to the DOE, its operations contractor Washington River Protection Solutions (WRPS) has made significant progress on Basin 41 at the Liquid Effluent Retention Facility (LERF) since concrete was first poured for the perimeter one year ago.

Work crews at the Department of Energy's Hanford Site recently completed the first transfer of test water from the Waste Treatment and Immobilization Plant's Effluent Management Facility to the nearby Liquid Effluent Retention Facility (LERF). The transfer of 6,000 gallons was the first simulation of the process that will be used to treat secondary liquid waste from the plant’s Low-Activity Waste Facility during operations to treat tank waste.

“This is a tremendous accomplishment that culminates years of work by our team and alumni toward being ready for hot commissioning,” said Valerie McCain, project director and senior vice president for Bechtel National, Inc. “It’s an important step for the entire Hanford team and our collective mission of protecting the Columbia River and its shoreline communities.”

Bechtel National is a contractor of the DOE's Office of Environmental Management's Office of River Protection.
