BC has a rich history with King County’s Wastewater Treatment Division that began in 1958 with the development of the County’s original sewer and drainage survey. In the 1980s, BC designed what was the first-ever renewable natural gas (RNG) from wastewater treatment system in North America and, at the time, the largest wastewater heat recovery project in the world. Well ahead of its time, the project supported the County’s energy management plan and allowed them to capture renewable energy in two innovative forms. Decades later, BC continues to work closely with King County to develop forward-thinking and multi-benefit solutions, including the County’s Clean Water Plan. This plan will guide the direction and prioritization of billions of dollars in future investments to achieve the best water quality benefits, provide equitable and affordable service, and address climate change and sustainability goals.
