Montavilla South Sewer Repair

Updated September 5, 2017Button. Click to sign up for email updates

Environmental Services has completed design on a project to repair or replace about 5,765 feet (over one mile) of 90-year-old public sewer pipes in the Montavilla Neighborhood, south of Stark Street, that are deteriorating due to age. The project will also install 11 new manholes, repair 38 manholes, and replace 78 public sewer connections to private properties. This investment in your neighborhood will ensure continued dependable sewer service and protect the public and our environment by reducing the possibility of sewage releases to homes, businesses, and streets.


We are in the process of selecting a construction contractor. Construction is anticipated to begin in the early spring of 2018, as soon as February, and take about a year and a half to complete. 

Another project in the Montavilla Neighborhood, north of Stark Street, will also be in construction. The two projects are separate, and contractors will be selected by early 2018. Although the projects will be managed separately, we understand that construction activities affect neighborhood travel routes and the broader community.

Night Work Approved

Environmental Services applied for and was granted a noise variance by the Portland Noise Office to allow open trench work and cured-in-place-pipe lining (CIPP) at the following location:

  • up to two weeks on SE 82nd Avenue and 234 feet west along Mill Street.

A variance is required when work occurs outside normal construction hours of 7 a.m. to 6 p.m., Monday through Saturday. This includes all work after 6 p.m. and before 7 a.m., Monday through Saturday, and all hours on Sunday.

Construction Methods

The city's contractor will use several different methods of construction to replace or repair sewer pipes. This project will include pipe bursting, cured in place pipe (CIPP) lining, and open trench excavation. 

The project includes replacing some manholes, storm drains, and sewer service branches that connect homes and businesses to the public sewer from the sewer main line in the street to the curb.
