Environmental Services continues construction of the Montavilla North Sewer Repair Project in the Montavilla Neighborhood (north of Stark Street). The project includes replacing or repairing more than three miles of deteriorating 100-year-old public sewer pipes, 87 manholes, and public sewer connections for 221 properties. These improvements will help protect the public and our environment by reducing the possibility of sewage releases to homes, businesses, and streets.

Location

The map below indicates pipe work locations and provides a construction update for the project.

Construction Schedule

Environmental Services and its contractor have completed most of the work to repair mainline public sewer pipes and service laterals in the project. A few locations, however, require design changes or specialized equipment and materials to complete repairs. When engineers finalize those plans and the contractor obtains the necessary equipment and materials, the contractor will schedule the work and complete the repairs.

Below is a summary of the remaining scheduled and unscheduled work.

Scheduled Work

Through the rest of November and into early December, crews will be at various locations in the project area. Crews will not work over the Thanksgiving holiday.

Crews will be at several locations to conduct post-construction inspections with closed-circuit-television cameras. The inspections are to verify that the pipe repairs were successful and the new pipe conditions and sewer connections are strong and secure.

Concrete will continue concrete work to repair manholes at various conditions. Dry weather is needed for the process to place and form the concrete followed by the process to strengthen, harden, and dry the restored concrete properly.

Work To Be Scheduled

A few locations are currently not scheduled. Environmental Services and its contractor will notify adjacent properties when the work is scheduled at the following locations:

• Public sewer easement between SE Gilham Avenue and SE Thorburn Street – Repairing a mainline public sewer pipe requires a newly engineered design plan due to the challenging steep grade. The timeline for this repair is uncertain.

• SE 70th Avenue north of SE Thorburn Street – Repairing one service lateral requires a newly engineered design plan and construction method for a pipe that could not be lined. This repair is expected to be completed by December 31, 2019.

• NE 75th Avenue south of NE Glisan Street – Repairing one service lateral requires a specially manufactured transition liner to complete the repair. This repair is expected to be completed by December 31, 2019.

• NE Pacific Street east of NE 82nd Avenue – Repairing a mainline public sewer pipe requires a specially manufactured pipebursting head and dry weather to complete the repairs. This repair will occur during the spring or summer of 2020.

• NE Pacific Street west of NE 87th Avenue – Repairing a mainline public sewer pipe requires a specially manufactured pipebursting head and dry weather to complete the repairs. This repair will occur during the spring or summer of 2020.
