Brightwater Conveyance System will expand Seattle's waste water treatment

摘要

Washington's King County is constructing a new regional wastewater treatment facility, called Brightwater, in response to growth in the greater Seattle region. Planning conducted in the late 1950s identified the need for two regional treatment facilities. Constructed in the 1960s, these plants have served the region well. However, an eventual need for a third facility was also recognized. The Brightwater project implements the final phases of the long-term plan. The project includes a new treatment plant and an extensive conveyance system. When completed in 2010, the Brightwater facilities will treat sanitary sewer flows from growing populations living in northern King County and southern Snohomish County. The new system will fulfill commitments to provide wastewater services to local jurisdictions and sewer service providers in the King County Service Area. It will also provide more flexibility in the operation of the King County regional wastewater system.
