Water Group 790 is part of a program established by the City of San Diego and the California Department of Public Health mandating the replacement of all cast iron water mains currently in service. After over 50 years of service, the 1950’s era cast iron pipelines have reached the end of their service life. Replacement is the most cost effective solution to providing long term water service to the hundreds of customers served by these critical pipelines. This is also a key opportunity to upgrade the water system to current standards and to take advantage of the opportunity to repair failing pavement and upgrade pedestrian walkways with ADA-compliant access ramps.

Water Group 790 is a design-build project that was awarded to Orion Construction and Harris & Associates. This job is located within two separate planned communities. The first is located within the Paradise Hills/Skyline Community Plan area which consists of the replacement of 14,137 lineal-feet of water mains ranging from 2” to 12” diameter. The majority of water mains to be replaced will be constructed within the existing paved City rights-of-way. Acquisition of water easements for portions of proposed water facilities (approximately 300 lineal-feet) will be required provided that an alternative method of providing service cannot be designed. Design will include abandonment of several water facilities which will need to adhere to all applicable City standards. The second site is located within the La Jolla Community Plan and consists of the replacement and addition of a total of 9,184 lineal-feet of water mains ranging from 6” to 12” in diameter. All new water main facilities will be constructed within the existing paved City rights-of-way. This area of the project will also require the abandonment of several water facilities which will need to adhere to all applicable City standards.
