Abstract: The Board of Supervisors of the San Luis Obispo County Flood Control and Water Conservation District (District) adopted the Final Environmental Impact Report for the Nacimiento Water Project (Project) in January 2004, thus directing staff to design the raw water conveyance that will supply up to 15,750 acre-feet per year from Lake Nacimiento located in San Luis Obispo County, California. The Project, illustrated in Figure 1, consists of a sloping multi-port intake and pump station facility, two intermediate pump stations, three storage tanks, control center, and approximately 45 miles of transmission pipelines ranging in diameter from 36-inches to 12-inches. The Project's Participants (customers) currently include Paso Robles, Templeton, Atascadero, and San Luis Obispo (Initial Participants) and later were joined by San Luis Obispo County Service Area 10-Zone A. The District began the design in 2005, and set specific design objectives for a sustainable and reliable water supply and for the efficiency of the water conveyance system to minimize electrical operating costs. This paper describes the sustainability aspects of the Project's design that include water supply sustainability, reduced energy use through energy efficiency initiatives, and balancing of resources.
