The communities of Fallbrook and Rainbow are requesting to join a water district based in Riverside, saying water in San Diego is too expensive. However, those who oppose the move say it will leave others paying $200 million more for water over the next decade. A vote is expected at the County Administration Center on Monday that would address the request from Fallbrook and Rainbow to get their water from an agency in Riverside County. "San Diego County's economy runs on water," Jerry Sanders said, from the Chamber of Commerce. Rainbow Municipal and Fallbrook Public Utility are the two out of 24 San Diego County Water Authority Districts looking to detach from the mainstream water supply and instead get water from a wholesaler in Riverside County. The two North County communities say it would save residents there close to $8 million a year and help the agriculture industry, which has dried up due to rising water costs. But other local leaders want them to stick with San Diego's supply, saying otherwise, it will cost everyone else $200 million more over the next decade if they stop paying their share.
