Project Description
This project will require excavating one access pit over the interceptor pipeline. The project will also include recoating existing maintenance-holes in this segment of the interceptor. This rehabilitation project will address critical pipeline corrosion and reduce the risk of pipe failure.

Slip Lining: Less time, less construction, fewer traffic impacts.
Slip lining is a trenchless method used to rehabilitate existing pipelines with minimal excavation. In this process, a slightly smaller, prefabricated pipe is inserted into the damaged host pipe and then grouted into place. This technique restores the structural integrity of the pipeline, prevents leaks, and extends its service life. Slip lining significantly reduces construction time, costs, and surface disruption, making it a less invasive alternative to traditional pipe replacement methods.
Workplan and Schedule
Construction and rehabilitation of the Alameda Interceptor will begin in the Fall 2026 and continue through March 2027.
Work schedule
- Monday through Friday. 7 am to 5:00 pm.
- Some night and weekend work will be required.
- The schedule is subject to change.
- Work hours may vary depending on project needs.
- Some night and weekend work may be required.
What to expect
- Construction equipment and materials will be temporarily located within the area.
- Noise from construction equipment is expected.
- Lane closures and associated traffic control will last four to six months.
- Potential night work. Notices will be sent out when needed.
- Two access pits will be excavated to facilitate the insertion of the slip line pipeline to the interceptor pipe.
- When construction is complete, all work areas will be restored to preconstruction conditions.
