Voters in Fallbrook and Rainbow approved of detaching from the San Diego County Water Authority for cheaper water in Riverside County in early voting results Tuesday night. After nearly three years of battling the Water Authority over what they say is increasingly high water rates, voters have had enough. … In July, the San Diego County Local Agency Formation Commission (LAFCO) approved the request for Rainbow Municipal Water District and Fallbrook Public Utility District to leave the Water Authority for Riverside’s Eastern Municipal Water District. Detachment is a two-step process. After LAFCO’s decision, voters in both Rainbow and Fallbrook would also need to approve the detachment.
