Extended Hours Needed

Construction crews have been diligently working to reline the pipeline. To complete the project on time and resume water deliveries to member agencies in late June, the contractor will need to work extended hours the last several months of the project. The new construction hours will be 7 a.m. - 10 p.m., Monday through Saturday, and 8 a.m. - 10 p.m. on Sundays. 

If you live near the project areas, or portals, you should have received a doorhanger alerting you that you may see lights and hear construction vehicles and some workers above-ground as they enter and exit the pipeline portals. The contractor will limit above-ground activities, as much as possible, during nighttime extended hours to limit impacts to project neighbors.

Thank you for your patience and we apologize for any inconvenience. 



Generally, relining construction rehabilitates segments of pipelines based on their age and the need for improvements. The Sweetwater to Lower Otay Relining Project involves rehabilitating approximately 5.4 miles of large diameter pipeline that traverse the communities of Bonita and eastern Chula Vista (Eastlake, Otay Ranch, as well as the Otay Ranch Preserve and Lower Otay County Park).

The construction crews will conduct most of the work underground, inside the pipe. They get to the pipe by excavating, establishing, and entering the pipeline through 17 access sites, or portals. Large wooden sound walls will be temporarily placed at portals, as needed, to comply with environmental regulations and ease noise impacts to residents.

Once this project is complete, the Water Authority will have rehabilitated approximately 38.9 miles of the existing 82.5 miles of Pre-Stressed Concrete Cylinder Pipe (PCCP). For information on PCCP and the Water Authority’s relining program, please visit www.sdcwa.org/pipeline-relining.

Project Portal Location Map

Location of Construction Portals (Access Points)

Pipeline relining is conducted in several phases; using portals developed by removing 40-feet of existing pipe to gain access to the interior of the pipeline and install relining materials. These 17 construction portals remain exposed but are gated and secured during construction. Not all portals are active at the same time, however. Work shifts from one portal to another depending on which phase is under way. The contractor usually works in a north to south pattern.
