Transcript Tour of the Brightwater Education Center

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.

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.

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.

species found in the Snohomish River
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, fivemile wastewater pipeline to Everett’s
sewage plant. The city is in talks with
Everett officials to make that happen.
