SEATTLE, Aug. 22, 2006 -- In October, King County will advertise a request for qualifications and proposals to design and build a deep-water marine outfall for the Brightwater treatment system project north of Seattle, WA.

The selected design-build team will complete the outfall design, which is now at 30% completion. As now planned, the outfall will consist of a 60-inch diameter pipe extending 4,700 feet from Point Wells into Puget Sound. The 500-foot diffuser at the end of the pipe will be about 600 feet deep.

Firms and teams will be evaluated through the county's RFQ procurement process. Those determined to be qualified will then be invited to submit proposals and participate in the remainder of the selection process. King County expects to award the design-build contract by July 2007.

King County has already selected Sacramento-based Vanir Construction Management, Inc. to provide construction management services for the outfall project.

The total construction cost for the entire Brightwater system, which includes a treatment plant and a 13-mile conveyance pipeline besides the deep-water marine outfall, is an estimated $1.62 billion.

When procurement packages are advertised, they will be available on the King County Procurement and Contract Services Web site at http://www.metrokc.gov/procurement/rfp_rfq_itb/default.aspx or by calling Christy Trautman at 206-684-1862.

Information about the Brightwater project is available on the Web at http://dnr.metrokc.gov/wtd/brightwater/

People enjoy clean water and a healthy environment because of King County's wastewater treatment program. The county's Wastewater Treatment Division protects public health and water quality by serving 17 cities, 17 local sewer utilities and more than 1.4 million residents in King, Snohomish and Pierce counties. Formerly called Metro, the regional clean-water agency now operated by King County has been preventing water pollution for more than 40 years.
