The project will include the installation of an air release valve. This will regulate air pressure inside the sewer pipes, help the pump station run more efficiently, and prolong the working life of the sewer system.
The pump station is located on NE 6th Drive at NE Vancouver Way. The air release valve will be installed in NE Vancouver Way at NE Martin Luther King Boulevard.
What’s Happening Now?
Throughout the project design process, project team members will visit the pump station and the location of the future air- release valve and collect information that will help them develop a successful project. You may see crews conducting survey, locating underground utilities, taking soil samples, and doing other field activities at the air- release valve location.
We Want to Hear from You
Environmental Services will inform businesses and residents about project activities and respond to questions and concerns in a timely manner. Please let us know if you have concerns such as business operations, local access, delivery routes and schedules, or other concerns.
What to Expect
Most of the work to improve the pump station will be conducted on-site on the pump station property and have minimal impacts on the nearby communities.
This project also includes construction of the new Air Release Valve in NE Vancouver Way at NE Martin Luther King Boulevard. You can expect the following impacts during construction at this location:
Lane restrictions: one lane may be closed near the work area
Traffic delays: expect traffic delays in and near the work area
Bike lane closure: bike lane will be temporarily closed, and bike traffic rerouted
The NE 6th Drive Pump Station has not had mechanical, electrical, or control system upgrades since its original construction in 1977. The upgrade will include designing and constructing modern equipment and controls that meet current and future demand on the public sewer system.
Key upgrades at the pump station location include:
Expansion of the current pump station footprint
Upgrade of the sewage pumps to support higher sewage and stormwater input
Upgrade of the wet well, which receives sewage from the neighborhood
Upgrade of the odor control system
Addition of a concrete enclosure for the electrical equipment and an ADA-compliant restroom
In addition, an Air Release Valve will be installed in NE Vancouver Way at NE Martin Luther King Jr Boulevard.
What are air release valves?
Air release valves are installed at points in a pipeline where air naturally collects. The trapped air can cause pump failures, corrosion, flow issues, and surges of water and pressure. Unnecessary air in the pipeline also makes the pump station work harder, consuming more energy. An air release valve continually releases excess air out of the system and into the atmosphere, resulting in smooth and efficient operation. Once installed, it operates automatically. Odor treatment will be provided through carbon cannisters, which are reliable and easy to maintain.
