Document Description
The project includes the replacement of approximately 4,000 linear feet of the Otay Pipeline 2 segment A6 40-inch steel pipe with a 54-inch steel pipe in the same underground location except under Salt Creek, where the pipe will be replaced directly adjacent to the existing pipe. The Otay Pipeline 2 was installed in 1958. The A6 segment is currently not in use and is proposed for replacement because it is in poor condition, with several portions of the current pipe exposed and corroded/oxidized. The project would replace and upsize this pipe to provide a redundant water supply line to handle current and anticipated future water flows from the Otay Water Treatment Plant to users in the City of San Diego. Upon completion of the pipeline replacement, approximately 10-foot-wide internal access roads would be graded to connect the existing external access roads to the five air vacuum and five blow-off valves for long-term maintenance access. The internal access roads would be a permanent impact.
