Week of June 24, 2019:
Potholing work has been completed, and contractors have begun work preparing the pipelines for the cured-in-place lining part of the project. The lining work is expected to begin July 12 and will require night and weekend construction due to the number of traffic lane closures required and the curing time needed to install the pipe liner. Weekend/night work hours will be from 9 p.m. Friday through 5 p.m. Sunday on the weekends of July 12, 19 and 26. This work will occur in Phase 2 of the project.
Week of June 10, 2019:
Work is continuing on the potholing phase of Phase 2 of the project.
Week of June 3, 2019:
Phase 2 construction will start June 5 at construction area 7, located to the far right in the project map.
Week of April 29, 2019:
Phase 1 construction has been completed and put into service.
Week of April 8, 2019:
The completed section of pipeline for Phase 1 of the project has passed its pressure test, and the District is conducting a seven-day operating test to run sewage flow through the pipeline. A video inspection of the pipeline will follow that test to determine whether that phase of the project can be put into service.
Week of March 25, 2019:
Vault work has been completed for Phase 1, and a high-pressure testing of that segment of pipeline is scheduled to take place next week.
Week of March 11, 2019:
Vault work is progressing well, and final paving of the area in Phase 1 is expected to be completed by early next week at the latest. A CCTV inspection of the sewer main identified wrinkles in the cured-in-place liner at two bends in the pipeline that will require the District to go in and replace those sections of pipe. This work will be less intrusive than the other work done so far. Plans for that work are being finalized.
Week of Feb. 25, 2019:
Hydraulic pressure-testing of the installed segment was successfully completed. Installation of the access vaults, pipe fittings within the vaults, pressure-testing of the aggregate OCSD portion of the pipe and pavement rehabilitation for Phase 1 will occur in the coming weeks.
Week of Feb. 4, 2019:
Rain has delayed the installation of CIPP liner at the third and final segment of Phase 1, located east of the other two construction areas. Weather permitting, the work will take place from 9 p.m. Friday, Feb. 8 through 5 p.m. Sunday, Feb. 10.
Week of Jan. 14, 2019:
Crews will be working consistently from 9 p.m. Fridays to noon on Sundays the weekends of Jan. 18, 25 and Feb. 1 to install a cured-in-place-pipe liner in the force main at the three construction areas located within Phase 1 of the project.
Week of Jan. 7, 2019:
Excavation work has been completed at vaults 1, 2 and 3. Pipe-cutting will take place this week at each location, followed by a dewatering process and pipe-cleaning on Friday. The pipe-cleaning is scheduled to take place on Friday night after 9 p.m.
Week of Dec. 17, 2018:
Roadway construction for Phase 1 began this week to excavate access pits near the intersection of Michelson Avenue and Jamboree Road. Traffic controls include the closure of left-turn lanes from westbound Michelson onto southbound Jamboree. Excavation work will move eastward on Michelson as the project progresses.
Week of Oct. 15, 2018:
Revised plans have been submitted to the city for review and the new design should be finalized next week.
Week of Oct. 1, 2018:
Conflicts with a utility line discovered during the potholing process resulted in a delay as plans were redesigned. Work is expected to resume in mid-October.
Week of Sept. 17, 2018:
Work began this week identifying access pit areas. Road construction will begin next week for Phase 1 of the project, beginning at the intersection of Michelson and Jamboree.
Week of Sept. 10, 2018:
Excavation of access pits 1 to 3 (Phase 1) is expected to commence next week.
Week of Aug. 6, 2018:
Phase 1 construction is scheduled to begin Aug. 20 at the construction area farthest west, close to the intersection with Jamboree Road. A left turn lane from westbound Michelson to southbound Jamboree will be closed during construction hours, and traffic will be severely impacted.
