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.

Environmental Services – your sewer and stormwater utility – is designing a project to repair an odor control facility and replace odor control equipment near the Ankeny Pump Station in Tom McCall Waterfront Park. The Ankeny Pump Station has been operating since the 1920s. In 2015, the vault containing equipment that helps to control odor flooded. This project will repair the vault and replace damaged equipment. It will help reduce odors from sewage gasses and ensure the proper functioning of the pump station.

ScheduleAnkeny Pump Station Project Map

Design work has begun and will continue through the end of 2020. Construction is anticipated to begin in the Spring of 2021. Construction work will take about four months to complete.

Sampling and Site Investigation

Over the next several months, crews will be in the project area locating utilities, surveying, inspecting pipes and manholes with closed circuit TV, and drilling to take soil and pavement samples. These activities occur over time, rather than all at once. For more information about these activities, see

Pump Stations and Odor Control

Pump stations are an important part of the City of Portland’s sanitary sewer system. They help move waste water from low points in the system in to pressurized pipes that carry waste to the treatment plant. Odor control equipment filters out foul odors from the air before they can be released to the surrounding neighborhood.
