Video: Brightwater treatment plant introduces tunneling equipment
Narrator says
With that christening, King County’s Brightwater treatment plant welcomed “Luminita” a two thousand ton tunnel boring machine to the worksite.
Luminita is one of four boring machines that will dig a 13 mile tunnel from the Brightwater plant location north of Woodinville to a deepwater outfall off Point Wells in Puget Sound.
The tunnel will carry clean, treated wastewater from about 250-thousand homes and businesses in North King County and South Snohomish County to the sound, plus hold pipelines that will distribute reclaimed water for irrigation and industrial uses.
Lots of construction workers and interested community members on hand for the christening, and King County Councilman Larry Gossett helped launch the tunnel boring machine.
Larry Gossett/King County Councilman says
This is the largest wastewater infrastructure project we’ve ever undertaken here in King County, since we built two regional, but much small treatment plants back in the 1960’s.
So 250-thousand people will be served by this facility that we are going to be building over the next few years, for years and years to come.
Narrator says
The tunnel boring machines will carve out a hole 16 feet in diameter hundreds of feet below the ground, and are expected to take about 14 months to complete the task. Construction of the Brightwater treatment plant is expected to be completed and online in 2010.
