Brightwater construction contracts
The King County (Washington, USA) Wastewater Treatment Division is making major improvements to its regional sewage treatment system, which are needed to handle rapid population growth in the greater Seattle/Puget Sound region. The center piece of these improvements is the Brightwater Project which will consist of a 36MGD ADF Wastewater Treatment Plant utilizing MBR technology and the associated conveyance system and marine outfall.
This page provides information about the major construction contracts for the Brightwater Project. Please note that most of the contracts have already been awarded. Also, many smaller contracts for construction, consultant services, and goods and services are not listed here. King County's procurement process is administered by the Procurement and Contract Services Section: http://www.metrokc.gov/procurement/default.aspx.
