Slide 2 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 Slide 3 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 Slide 4 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. What can be done at the Center? Slide 5 Brightwater Wastewater Treatment Plant Education focused on beneficial reuse and conservation of resources Enlightening our youth the future stewards Reclaimed Lumber Reuse water and energy Natural light Construction products from within 300 miles Slide 6 The art plan for Brightwater was completed in 2003 Blown Glass Sculptures Lab bottle sculpture Slide 7 Interior Art at Brightwater Illuminated Bacteria The seven screen art piece Circulator Slide 8 Nature Trails at Brightwater Slide 9 Purple pipes, pumps and valve boxes are used for water reuse Entrance to Brightwater Slide 10 Sewage is cleaned to near drinking water quality Slide 11 You Can Help Grease in a sewer line Slide 12 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 Slide 13 Carnation, Washington Wastewater Treatment Plant Slide 14 Carnation WWTP Operations Building Slide 15 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 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/Operator Cost: $23 million Completion: 2008 Hookup quoted by plant staff @ $7000 600 homes and approximately 100,000 g/day Slide 16 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. Slide 17 Video of a vacuum collection system Slide 18 SCADA Supervisory Control and Data Acquisition SCADA allows the Operators to monitor the process, setup alarms, create graphs, enter set points and retrieve real time data Carnation WWTP control room Slide 19 Preliminary Treatment Coarse screening - rags, sticks and larger debris Grit removal Fine Screening removes anything < 2 millimeters Fine screenings Drum Screenings Wash and Press Slide 20 Screened Influent with a Supernatant return Slide 21 Ultrafiltration The filter size at Carnation is.02 microns Slide 22 Zenon Membrane Cassette. Close-up of the microscopic pores Slide 23 Natural lighting was used to save on electricity located over the fine screening drums Slide 24 The two Berson Inline 7500+ UV units provide effluent disinfection Slide 25 The Carnation, WA, Waste Treatment Facility discharges its reclaimed water to the Chinook Bend Wetlands and Snohomish river 1 mile from the plant Water Pole An art piece to measure river level Slide 26 Slide 27 Snohomish CSO Pumping Station is made with contrasting bricks and decorated with steel sculptures of various fish species found in the Snohomish River Slide 28 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 Slide 29 Snohomish 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. Slide 30 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. Slide 31 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.
