Project Scope

The Jenny Lind Water System Tank A-B Transmission Pipeline Project is located in Rancho Calaveras near Valley Springs in western Calaveras County, CA. The existing 8-inch diameter asbestos cement pipe installed in the 1970's is being replaced due to age, poor condition and series of failures and repairs. The project consists of furnishing and installing approximately 20,000 feet of new 12-inch and 14-inch diameter ductile iron pipeline between existing Tanks A and B. The new pipeline will operate at pressures up to 205 psi and have mechanically restrained joints. In addition, this project includes pressure reducing stations, air relief valves, gate valves, and other appurtenances. Also, the project requires modifying the Tank A pump station outlet piping and Tank B inlet and outlet piping arrangements. The alignment starts at Tank A on Heinemann Dr, continues south along Hartvickson Lane, Baldwin Street, and Usher Drive before ending at Tank B along Wind River Drive. The replacement pipeline will be placed within the existing pavement section of the County Road right-of-way. The project is subject to a Calaveras County Public Works utility encroachment permit and requires deployment of a traffic control plan and linear SWPPP. Environmental conditions detailed in a project-specific CEQA Initial Study, Mitigated Negative Declaration (ISMND) and associated Mitigation Monitoring and Reporting Program (MMRP) requirements must be adhered to during the course of work.
