Since the days of the Kumeyaay, survival in San Diego has depended on the availability of water. While blessed to live in one of the most beautiful places in the world, the fact remains we must rely upon outside sources to meet our water needs. The level of this dependency, however, is more a matter of resolve rather than circumstance. In the late 1990s, this situation reached a critical point when San Diego County found itself importing more than 90 percent of our water, and our primary supplier, the Metropolitan Water District (MWD) in Los Angeles, was taking action that could reduce our water allocation by up to 50 percent.
