Environmental Services is working on a project to reduce sewer odors and increase the capacity of the Southwest Parallel Interceptor sewer system. The project is designed to accommodate current needs and potential growth. Since February, the contractor has installed about 1,000 feet of 24-inch concrete pipe and six manholes along SW Taylors Ferry Road, and three manholes on SW Virginia Avenue.

Environmental Services is working on a project to reduce sewer odors and increase the capacity of the Southwest Parallel Interceptor sewer system. The project is designed to accommodate current needs and potential growth. Since February, the contractor has installed about 1,000 feet of 24-inch concrete pipe and six manholes along SW Taylors Ferry Road, and three manholes on SW Virginia Avenue. The contractor will install 800 feet of 48-inch concrete pipe along SW Virginia Avenue, and a permanent odor control facility to the east of SW Taylors Ferry Road.

DEVELOPMENTS OF NOTE
- Due to subcontractor schedule conflicts, pipe lining has been rescheduled for early December.
- In observance of the Thanksgiving holiday, the contractor will not work beginning noon Wednesday, November 25, through Sunday, November 29.
Please be aware that the schedule is subject to change due to conditions underground, weather, bypass pump operation, traffic impacts, subcontractor schedules and availability of materials.
WHAT TO EXPECT DURING CONSTRUCTION
- For a full list of what to expect, go to www.portlandoregon.gov/bes/SWVentilation.
- Construction hours are 7:00 a.m. to 6:00 p.m. Monday through Saturday.
- Once work crews finish installing the final pipes, the contractor will begin sewer repairs with cured-in-place pipe-lining.
- Pipe-lining is likely to take place in December. This work is dependent on a window of good weather, and may take place on a weekend. Confirmation for this work will be sent about a day in advance to the email update list and on the project website.
- Go to www.portlandoregon.gov/bes/PipeLining for information about what to expect during pipe-lining.
- During pipe lining, bypass pumps move sewage around the section of pipe under construction. When it rains, stormwater runoff can increase flow beyond the capacity of bypass pumps, which can postpone construction.
- The contractor maintains local access, but construction disrupts the normal use of driveways. There may be traffic delays during work hours.
- A city construction inspector is on-site during work hours, and may be able to assist you with an immediate construction need. Inspectors typically wear a City of Portland safety vest and a hard hat.
