Sweetwater to Lower Otay Pipeline Relining Project
Hot Off the Press
Construction-Related Activities Have Begun
In September, construction activities related to the project began. Project neighbors, especially those living near access roads and portal locations, will notice crews clearing and grading areas in and around access routes and portals and installing wooden sound walls, preparing the areas for excavation and heavy construction. The contractor will begin excavation and heavy construction activities in November.
Final Environmental Document Approved
The environmental document, a Mitigated Negative Declaration, for this project was approved by the Water Authority's Board of Directors at their March 28, 2013, meeting.
The document and its appendices are viewable by clicking the link in the "Environmental Documents" section.
A letter and postcard were mailed to residents, businesses, and stakeholders to notify them about the project and availability of the environmental document. To view the postcard, click here. It is also available in the "Community Outreach" section.
ABOUT THIS PROJECT - DETAILS
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.

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.
