Tour of the Brightwater Education Center, Carnation WWTP and Snohomish Pump Station

Brightwater Education CenterBrightwater Center is located near Bothell and Woodinville in Snohomish CountyA new park with three miles of walking trails, 70 acres of public open space and 40 acres of natural habitatA community center with rentable meeting rooms for the publicA clean water learning space featuring learning opportunities in both indoor and outdoor settingsIntegrated with the Wastewater Plant and a Park and Trail system

No soil was hauled away, instead large mounds were designed to block less pleasant views and added character to the natural areas; saving money and reducing green house gas

The community gathering spaces at Brightwater Center will provide meeting spaces for community groups, conferences, business meetings, weddings and other special events. The community center has a large meeting space that can accommodate up to 250 people and can be broken down into three smaller configurations. Amenities include an exhibit hall, kitchen facilities, a resource library, private dressing room and ample parking.

Carnation, Washington Wastewater Treatment Plant

Carnation WWTPOperations Building

Carnation WastewaterThis LEED Silver wastewater treatment facility was master planned and designed by MWA and Carollo Engineers to respond to its limited site area and historic context within a small bedroom community of Seattle.The plant is designed to meet the citys current and (phased) future needs. The small scale neighborhood plant, adjacent to a new housing development uses the advanced treatment technology of a membrane bioreactor to meet Class A, reclaimed water quality standards. Reclaimed water from the plant is used to create and enhance wetlands in the state Chinook Bend Natural Area while eliminating adverse impacts to public health and the environment. Carollo Engineers/King County, WA Owner/OperatorCost: $23 millionCompletion: 2008Hookup quoted by plant staff @ $7000 600 homes and approximately 100,000 g/day

Vacuum Station Owned and maintained by the City of Carnation The system consists of about 11 miles of vacuum sewer pipe, five main vacuum sewer trunk lines, a single vacuum station, and about 400 vacuum valve pits.

Snohomish CSO Pumping Station is made with contrasting bricks and decorated with steel sculptures of various fish species found in the Snohomish River

History of the Snohomish Pump StationThe pump station was built as part of a settlement between the city and Puget Soundkeeper Alliance, which sued the city under the federal Clean Water Act in 2003 because of the number of raw sewage overflows spilling into the Snohomish River each yearSnohomish Pump Station The pump station carries sewage and storm water in new separated pipes to the citys wastewater plant for treatment. This will prevent illegal amounts of raw sewage from spilling into the Snohomish River during heavy rains. Before, both flowed through the same pipes in the historic part of the city and during heavy rain events raw sewage would overflow and enter the river untreated. The Snohomish River eventually drains into Puget Sound, and the health of the Sound is declining. The quality of the Snohomish River is one small but important part of the larger health issues of the Sound.Cost The project was made possible in large part by a state grant of $5.4 million, as well as a $1 million state Department of Ecology storm water grant. This was approximately 80% of the cost.

The Future for Snohomish Wastewater The citys long-term plan is to get out of the sewage business. It is currently working on building a $40 million, five-mile wastewater pipeline to Everetts sewage plant. The city is in talks with Everett officials to make that happen.
