A complex marine construction project that was successfully completed ahead of schedule and under budget helped a Brightwater consultant earn an Award of Excellence from the Consulting Engineers of British Columbia (CEBC).
Dayton & Knight Ltd., which served as the principal design consultant for the Brightwater marine outfall, was honored at a ceremony in Vancouver last month.
King County awarded the design-build contract in 2007 to Triton Marine Construction Corporation. They completed construction a year ahead of schedule in late 2008 at a cost of $29 million, 23 percent less than the original estimate of $38 million.
King County and Vanir Construction Management managed the project.
“The award is well-deserved,” said Wastewater Treatment Division Director Christie True. “Dayton & Knight Ltd’s contribution to the Brightwater project reflects our commitment to protect public health and the environment while maximizing the investment of ratepayer money in critical infrastructure.”
“The Brightwater project outfall presented many unique engineering challenges, and we are delighted at the overall design and construction success,” said Dayton & Knight vice president John Boyle, M.I.C.E., P.Eng. He stressed that the award reflected the professional thoroughness of the whole team lead by Triton Marine Construction Corp.
The outfall design had to meet critical engineering specifications, including stringent seismic standards and hydraulic requirements to enable the treated effluent to mix effectively with waters of Puget Sound.
The firm also had to design using high quality materials to guarantee a minimum 75 year operating life, and to ensure the design would reduce impacts to the sensitive marine environment during both construction and operation.
The 650-foot-deep outfall will serve as the primary discharge point for highly treated wastewater effluent when the Brightwater treatment plant north of Woodinville begins operating in 2011.
Now resting on the floor of Puget Sound a mile off Point Wells, it is one of the world’s deepest outfalls.

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 districts 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.
