Force Avenue Pump Station


Sign up for email updates 

The City of Portland’s Bureau of Environmental Services is continuing our work to repair and replace critical sewer and stormwater infrastructure. Environmental Services will continue to provide information and updates on construction schedules and activities during the COVID-19 emergency. 

Updated July 7, 2020

Environmental Services is designing a project to remodel the Force Avenue Pump Station, located at 11415 N Force Avenue. The pump station, constructed in 1974, is more than 40 years old and needs upgrades to increase pumping capacity and meet standards for access and safety. This upgrade project will improve reliability, accommodate growth and future demands on the public sewer system, and protect public health, water quality and the environment.


Design will continue through 2021. Construction is tentatively scheduled to begin in early 2022 and to be completed in the summer of 2023.

Project Map

The Force Avenue Pump Station pumps sewage and stormwater from north Portland to the Columbia Boulevard Wastewater Treatment Plant. The pump station service area includes Hayden Island, Tomahawk Island, and 2,130 acres of primarily industrial and commercial land, with some multi-family residential areas.

Site Surveys, Inspections, and Geotechnical Investigations

Environmental Services and its contractor have completed surveys of the pump station property to investigate existing sewer pipes and manholes, identify underground public and private utilities, locate and measure trees and fences, and take other ground measurements (elevations, slopes, etc.) that will help engineers design the upgrade project. The project has also completed an assessment of the pump station’s condition and operation.

In addition, the project has conducted geotechnical investigations and groundwater monitoring activities to collect soil, rock, and plant samples and to monitor groundwater levels in the project area.

Proposed Pump Station Improvements

Environmental Services continues to study design options for the following pump station improvements:

  • Determine feasibility of expanding or relocating the existing pump station
  • Replace existing pumps and equipment with new submersible pumps in a new wet well
  • The new structure will be earthquake resistant
  • Increase wet well capacity to accommodate future development
  • Replace existing generator shed with a new electrical control systems building
  • Replace outdated mechanical, electrical and control equipment and systems and locate the new systems in the above ground electrical control systems building
  • Improve access for operations and maintenance
  • Install security fencing
  • Provide odor treatment
  • Develop a permanent easement for the upgraded facility
  • Develop property frontage improvements if required
