The Brightwater Center is one of the largest public works projects ever undertaken in Snohomish County. It took 14 years to build and cost $1.8 billion. The plant treats millions of gallons of water that runs through toilets, bathtubs and sinks from tens of thousands of homes and businesses in south Snohomish and north King counties.

A major part of the facility is a 13-mile tunnel that runs from the Maltby plant along Highway 9 to Point Wells at the Snohomish-King county line.

For more information or to request accommodations for people with disabilities at the open house, contact Kristin Covey at 206-263-9412, 711 TTY Relay, or
