THE CALLEGUAS WATERSHED BRACKISH GROUNDWATER PROGRAM (PROGRAM) INCLUDES A SUITE OF THREE CAPITAL PROJECTS AIMED AT DESALTING BRACKISH GROUNDWATER TO FACILITATE THE DEVELOPMENT OF LOCAL, DROUGHT RESISTANT WATER SUPPLY. THE PROGRAM IS PROPOSED BY THE CALLEGUAS MUNICIPAL WATER DISTRICT (CALLEGUAS), IN CONJUNCTION WITH PARTNER AGENCIES CAMROSA WATER DISTRICT (CAMROSA), THE CITY OF CAMARILLO (CAMARILLO), AND VENTURA COUNTY WATERWORKS DISTRICT NO. 1 (VCWWD1). THE LOCATION OF THE PROGRAM IS IN THE CALLEGUAS CREEK WATERSHED (WATERSHED) IN VENTURA COUNTY, CALIFORNIA, WHICH SERVES AS A VITAL ECOLOGICAL RESOURCE, CULTURALLY SIGNIFICANT LOCATION, AND CRUCIAL WATER SOURCE FOR BOTH AGRICULTURAL AND URBAN COMMUNITIES IN THE AREA. THE WATERSHED ALSO FACES MANY CHALLENGES, INCLUDING WATER QUALITY ISSUES DUE TO SALT AND NITRATE LEVELS AND CLIMATE CHANGE RELATED IMPACTS TO WATER SUPPLY. CALLEGUAS AND REGIONAL PARTNERS HAVE LED EFFORTS TO ALLEVIATE WATER QUALITY ISSUES AND BUILD LOCAL SUPPLIES IN THE WATERSHED, INCLUDING DEVELOPMENT OF THE CALLEGUAS REGIONAL SALINITY MANAGEMENT PIPELINE (CRSMP), WHICH DISPOSES OF BRINE PRODUCED BY ENHANCED WATER TREATMENT AND MANAGES EXCESS RECYCLED WATER WHEN THERE IS INSUFFICIENT DEMAND OR STORAGE AVAILABLE. THESE PROJECTS WILL PRODUCE 4,684 ACRE-FEET PER YEAR (AFY) AT A COST OF $4,713 PER ACRE FOOT (AF), LESS THAN BOTH ALTERNATIVES EXPLORED, INCLUDING THE NO PROJECT AND MOORPARK DESALTER ALTERNATIVES.
