The Brightwater Sewage Treatment Plant in Everett, WA is scheduled to open in 2011. Mechanical breakdowns of two tunnel boring machines have halted the 13-mile tunnel which was to carry treated waste water to Puget Sound. Until the tunnel is complete, the treated waste water will be sent through existing pipes to the Westpoint or Renton treatment plant.
