Inverness System Planning Project

Sewer and Stormwater
In Planning
The Inverness pump station and force main system (The Inverness System) is nearing the end of its service life, and is in need of repair or replacement. This project will choose a preferred solution for repair and/or replacement that protects public health and the environment.
This project is in the planning phase. Planning and analysis will continue through the summer of 2024.

Project location

The Inverness Pump Station is in Northeast Portland north of I-84 and east of I-205, slightly north of the Columbia Slough and south of the Columbia River. It is in the Parkrose Neighborhood, due east of the Multnomah County Inverness Jail.  Two force mains connect the pump station to the Columbia Boulevard Wastewater Treatment Plant (CBWTP), running under Columbia Boulevard and Lombard Street in North and Northeast Portland.

The Inverness Pump Station serves a large area of Northeast Portland, and is located next to the Columbia Slough west of NE 122nd Ave.

What's Happening Now?

Environmental Services Staff is currently evaluating the Inverness System, collecting information on the condition of pipes and equipment, and identifying system needs.

In 2023 and 2024, the project team will develop a long term master plan. This master planning process will also look for opportunities to:

  • Protect and restore the Columbia Slough
  • Protect human and environmental health
  • Build economic prosperity
  • Address equity issues and enhance community relations
  • Improve resilience and service delivery reliability

Project Background

Environmental Services has identified improving the Inverness Pump Station and the force mains that connect it to the Columbia Boulevard Wastewater Treatment Plant as one of the the bureau's highest priorities after extensive evaluations of the pipeline and pump station system across the area.

Why is the Inverness System a High Priority?

Inverness System assets were built between 1985 and 1996 and are reaching the end of their remaining useful life. The Inverness pump station is also in an area with high seismic risk, and is in close proximity to the Columbia Slough - an environmentally sensitive wetland area subject to State and Federal regulations.

The Inverness System Area 

The Inverness System provides critical service to approximately 60,000 residents and businesses. The service area represents about 12% of the City of Portland population. It is about 50% commercial/industrial and 43% residential. Major landmarks within this area include Portland International Airport (PDX), Portland Air National Guard, Gateway/Mall 205 District, Portland Adventist Medical Center, the Marine Drive and Airport Way Commercial/Industrial District, and 13 Tier One Critical Facilities. There are approximately 58,000 jobs in the area, with a 12% predicted growth rate by 2035. The percentage of non-white population in the service area is higher than the Portland average, and the median income is lower.

Opportunities for Public Involvement

Environmental Services is committed to working with our community to ensure the best possible outcomes for our projects.  Staff are currently working on an outreach plan to engage members of the community in a conversation about what should be considered in the master planning effort.  Please check this website or sign up for email updates below to get up-to-date information on future opportunities to make your voice heard.
