Environmental Services is preparing to complete two remaining public sewer pipe repairs in your neighborhood that were originally part of the Citywide 2017 Sewer Repair Project. See map below. Although that project concluded in December 2018, Environmental Services was unable to repair the pipes due to changes in pipe condition. Repairing these pipes is still a priority. Therefore, the two pipes have been added to the SW Caruthers-Mill Sewer Repair Project. These sewer repairs will protect public health and the Willamette River Watershed by reducing the possibility of sewage releases to buildings and streets.


The two public sewer pipes are located in public right-of-way areas near SW 16th Avenue between SW Upper Hall and SW College streets and near SW 14th Avenue between SW College Street and SW Cardinell Drive.

Project Map

General Schedule 

Work hours are from 7 a.m. to 6 p.m. Monday through Friday, with Saturdays as needed.

Look-Ahead Construction Schedule

Construction activities may fluctuate in schedule due to weather, conditions underground, traffic impacts, subcontractor schedules, materials availability, and other factors.

December 12

Crews plan to TV the sewer mainline by running a camper down the manhole and into the sewer pipe at the following locations. This work will last approximately half a day at each location.

  • SW College Street
  • SW Cardinell Drive

Traffic Impacts

The upper part of SW College Street between SW 16th Avenue and the manhole halfway down the street will be closed for the morning, but one lane of SW Cardinell Drive should remain open during the afternoon work there. A flagged will be in place to direct traffic.

What to Expect during Construction

You can expect the following activities and impacts during construction:

  • Equipment that generates noise includes sewer cleaning trucks, compressors, light trucks, generators, pumps, and ventilation fans.
  • Vactor trucks will be in the area to operate vacuum pumps necessary to clean the pipes prior to the lining and maintain sewer service during the lining. Vactor trucks generate noise and can be in place for up to several hours at a time. 
  • In the event of a sewer backup, storm drainage problem, or clogged catch basin, call 503-823-1700 to report the problem and the location.


This schedule may change due to weather, conditions underground, traffic impacts, subcontractor schedules, materials availability, and other factors.
