Tour of the Brightwater Education Center, Carnation WWTP and Snohomish Pump Station
Brightwater Education Center Brightwater Center is located near Bothell and Woodinville in Snohomish County • A new park with three miles of walking trails, 70 acres of public open space and 40 acres of natural habitat • A community center with rentable meeting rooms for the public • A clean water learning space featuring learning opportunities in both indoor and outdoor settings • Integrated 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
What can be done at the Center? 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.

Understanding Wastewater Treatment Water cycle and nutrient cycle Human impacts to water quality Pollution prevention and water conservation How wastewater treatment protects human health How wastewater treatment protects ecosystems How physical science, biology and chemistry are used to clean water and recycle water and nutrient resources Stormwater and groundwater impacts on water management Understanding of infrastructure – aging systems, related jobs, impacts of population growth
Carnation Wastewater • This 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 city’s 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: 2008 • Hookup 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.

History of the Snohomish Pump Station The 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 year
Snohomish Pump Station The pump station carries sewage and storm water in new separated pipes to the city’s 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 city’s 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 Everett’s sewage plant. The city is in talks with Everett officials to make that happen.
