Concrete Sewer Lining Project

Project Update: October 1, 2018 (FINAL PROJECT UPDATE)

This project involves rehabilitating concrete sanitary sewers using a trenchless lining process along a section of Pebble Valley Rd, a section of Silvernail Rd, and in various off-road easements. Sanitary manholes will also be repaired as needed.

This week, the contractor completed all work except for a couple of manholes that need to be abandoned in the easement area. These will be abandoned once the area has dried out and colder weather has set in.

Next week the contractor will rehabilitate the last remaining sanitary manholes and grout two laterals along Silvernail Rd.

Streets with restricted access for the next week:

  • Silvernail Rd will have short term work in the terrace area west of Marshview St to accommodate the lateral grouting operations. Sections of the westbound outside lane may be closed. At least one lane in each direction will be maintained.

Streets that will have No Access:
• None. All streets will have access.

This project will involve reconstructing or repairing manholes as needed, cleaning the sewers, installing a structural liner in the sewer, sealing the joint between private service laterals and the public sewer, and any restorations that may be necessary as a result of the work.

The actual installation of the structural liner normally requires less than 24 hours to complete for each pipe section. During this time, service lateral connections will be sealed off at the sewer main in the street. Once the liner is installed, the service lateral will be reopened and sewer use can return to normal. If a user’s lateral connection will be impacted by the work, they will be asked to make limited use of their toilet facilities and refrain from doing laundry during the time period that the service lateral is sealed off. A few days prior to installing the liner, the contractor will place a notice on the user’s door as to the actual date and time of the limited water use period.

The project has been contracted to Visu-Sewer, W230 N4855 Betker Drive, Pewaukee, WI. Work is to begin in the spring with the project complete by September 28.
