Sweetwater to Lower Otay Pipeline Relining Project

 

Construction Complete

This project completed construction in 2014. Thank you for your patience.

ABOUT THIS PROJECT - DETAILS
 

Background

Generally, relining construction rehabilitates segments of pipelines based on their age and the need for improvements. The Sweetwater to Lower Otay Relining Project involved 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 conducted most of the work underground, inside the pipe. They got to the pipe by excavating, establishing, and entering the pipeline through 17 access sites, or portals. Large wooden sound walls were temporarily placed at portals, as needed, to comply with environmental regulations and ease noise impacts to residents.

Now that this project is complete, the Water Authority has 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.
