Montavilla South Sewer Repair Project Update: November 16, 2018
Environmental Services will begin construction in a few weeks on the Montavilla South Sewer Repair 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. Construction will have several phases and is anticipated to take up to 10 months to complete.
The map below shows the pipe work locations and construction methods for Montavilla South.
The construction contractor for Montavilla South will be J.W. Fowler. Construction is anticipated to begin in October 2018 and take about 10 months to complete.
*Schedule changes and inactivity during construction phases can occur due to a variety of factors, including conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials.
Another project in the Montavilla Neighborhood, north of Stark Street, will also be in construction. The two projects will be constructed separately by two different contractors. For more information about the Montavilla North project, click here.
Construction work from:
November 16 – November 30
Future Scheduled Work
The typical work hours for Montavilla South will be 7 a.m. to 6 p.m. Monday through Friday. If needed, the contractor can work the same hours on Saturday.
Environmental Services applied for and was granted a noise variance by the Portland Noise Office to allow nighttime construction on SE Mill Street between SE 80th and 82nd avenues. However, that sewer repair will be completed as part of a street improvement project to be constructed by the Portland Bureau of Transportation at a future date, tentatively scheduled for 2020.
This week and the following weeks, crews may be in the neighborhood preparing for construction:
These activities typically occur over time, rather than all at once. To learn more and see photos, click here.
The city's contractor may use several different methods of construction to replace or repair sewer pipes. This project will include cured-in-place-pipe lining (CIPP) and open trench excavation. After the contractor inspects the pipes to determine existing conditions, they may decide to change construction methods or even use another method, like pipebursting, at some locations.
The project also includes replacing some manholes, storm drains, and sewer service laterals that connect homes and businesses to the public sewer from the sewer main line in the street to the curb.
