NE 33rd Drive Pump Station Upgrades Project

Sewer and Stormwater
Environmental Services – the City’s sewer and stormwater bureau – is designing a project to upgrade a pump station in Northeast Portland. This project will replace the existing pump station with a new larger pump station.
Design has just begun and construction is anticipated to begin in 2024.

This project will increase pumping capacity, enhance accessibility for maintenance, and improve drainage. The upgrades to the pump station will help protect public health and the environment by reducing sewage backups to homes, businesses, streets and natural areas.

Project Area

This project is located at 7548 NE 33rd Drive, adjacent to the Columbia Slough. 

What's Happening Now

This past summer, City surveyors conducted a survey on and near the project site and adjacent property. The purpose of this survey was to collect information on existing features such as curbs, sidewalks, fences, trees, structures, utilities and to locate existing survey markers to record the right of way lines for the project. The information has helped City engineers and engineering consultants hired by the City to design the project.

What is a Pump Station?

Sewage, which is 99 percent water, flows downhill, and gravity is the main force that moves sewage through pipes. However, in low-elevation areas or where sewage needs to go uphill, pump stations push the sewage up so that gravity can take over again. Portland has nearly 100 pump stations with large underground tanks (also known as wet wells) in low-elevation areas. Pump stations are equipped with specialized pipes that are built to handle the force of sewage being pushed through them.  Pump stations also have equipment that helps control odor and protects the pumps.

How do we take care of Pump Stations?

Pump stations require periodic maintenance and upgrades to help accommodate growth and future demands on the sewer system. Modernization of mechanical, electrical, and other control systems improves pump station reliability, operation, and safety, which in turn protects public health and the environment.  In Portland, operators at the Columbia Boulevard Wastewater Treatment Plant monitor the City’s pump stations remotely to ensure proper functionality. They can quickly respond to emergencies like power outages or pump blockages.
