In 1991, the residents in the District service area voted to purchase an allotment of water from the State Water Project (SWP). The facilities to deliver this water were completed in 1997 by the Central Coast Water Authority (CCWA). The CCWA is a California Joint Powers Agency formed by its nine public agency members, including the District. The CCWA was formed to construct the necessary facilities to deliver State Water Project water to its members, and now operates and maintains the facilities. All of the Cachuma Project Member Units are also members of CCWA. State Water Project water deliveries to Santa Barbara County, including the District, began in 1997. This imported water is delivered to Lake Cachuma, where it is mixed with the Lake water and delivered to the District.
