Riverview Force Main Replacement Project

Environmental Services is planning a project on Highway 43 to replace an aging sewer main that carries wastewater from the Riverview Pump Station. The project will replace roughly 3,000 feet of failing sewer pipe along Highway 43 from the Riverview Pump Station south to SW Riverwood Road (see map). The pipe has experienced several failures in recent years, and this project will install a new pipe and reduce the potential for future leaks or breaks.

Night Work and Noise Variance Application

Portland noise code allows construction from 7:00 a.m. to 6:00 p.m. Monday through Saturday. Work outside of those hours requires a noise variance from the Portland Noise Office. Environmental Services will apply for a noise variance to allow night work during this project to minimize impacts on neighbors and traffic, and avoid conflicts with other construction projects in the area. The noise office can approve or deny a variance requested for extended work hours.

The noise variance application stipulates that crews will be on site working during the night, and will open up the road to through traffic during the day. Through traffic will also be allowed during overnight construction, but there will be some delays.

Questions or Concerns?

Your comments on the noise variance application are valuable and you can submit comments by letter, telephone or email.

Write to: Portland Noise Office, 1900 SW 4th Ave, Room 5000, Portland, OR 97204


Telephone: 503-823-7350

Or, you can contact Becky Tillson at 503-823-2827 or Any noise-related comments will also be forwarded to the Noise Office.


Work is expected to start in 2015 and construction should take about six months. The project team will coordinate the construction schedule with other sewer and road projects in the area to minimize impacts on residents and commuters.

We will continue to be in contact as the project progresses.
