Otay Second Pipeline Improvements Program

Otay Second Pipeline Improvements Program

The proposed project calls for the maintenance, repair, and, for some segments, replacement of the Otay Second Pipeline which was built in 1928-29. Due to the age of this utility line and the effect of corrosive forces on steel and cast iron pipe, it is necessary to replace or protect certain segments in need of repair. A condition assessment study determined that the life of several miles of pipeline can be extended through implementation of a cathodic protection system. Six phases for this project have been identified. Phase I consists of replacing approximately 1,200 if of pipeline in Alta View Drive. Phase II includes cast iron main replacements along Wightman Street and Highland Avenue, and installation of new pipe in 54th Street. Phase III includes installing a cathodic protection system along a total of approximately 58,000 if of the existing pipeline between Otay Water Treatment Plant and 54th Street. Phase IV includes the replacement of about 4,100 if of pipeline along Balboa Vista Drive from Chaumont Place to the intersection of Balboa Drive and Seifert Street. Phase V entails negotiating with the Sweetwater Authority to transfer approximately 30 domestic water services from the Otay Second Pipeline to the Sweetwater Authority. In Phase VI it is anticipated that a private developer would replace a 17,000-If segment of pipeline on Otay Ranch between Olympic Parkway and the South San Diego Reservoir, within new streets.
