The Brightwater project recently took a small but significant step towards completion in 2011.
On Friday, employees and contractors celebrated the completion of facilities that will one day connect Brightwater infrastructure to existing sewer lines, control odors, and deliver Class A reclaimed water to the Sammamish Valley.
Construction of the Brightwater North Creek Facilities Site Project, located near the intersection of Northeast 195th Street and North Creek Parkway in Bothell, was led by James W. Fowler Construction Company of Dallas, Ore. The final project cost was $10.49 million.
Newly completed facilities include a diversion structure and a connector pipeline that will enable untreated wastewater from two existing King County sewer lines – the North Creek and Bothell-Woodinville interceptors – to reach the tunnels that will carry flows to the new Brightwater plant when it begins operating in 2011.
These flows are currently treated at West Point Treatment Plant in Seattle or South Treatment Plant in Renton.
The contractor also completed a 2,300-foot-section of a 7-mile reclaimed water pipeline that will carry high quality reclaimed water produced at Brightwater to the Sammamish Valley for agricultural and industrial users, and installed a state-of-the-art underground odor control system to help ensure that the Brightwater conveyance system is a good neighbor to its host community.
Engineering design was led by MWH/Jacobs Associates, HDR Engineering, Tetra Tech and Carollo Engineers.
The Brightwater Treatment System Project also includes a 36-million-gallon-per-day treatment plant at the intersection of State Route 9 and SR-522, a 13-mile conveyance pipeline that runs beneath SR-522, Northeast 195th Street and the King/Snohomish County line, and a 600-foot-deep outfall a mile off of Point Wells in Puget Sound.
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.
