ABSTRACT
ABSTRACT: Los Angeles and San Diego have always been challenged by water resource scarcity. They have dealt with this problem by adding imported water to their local resources. They purchase imported water from the Metropolitan Water District of Southern California, which owns and operates the Colorado River Aquaduct and is entitled to control half the water the State of California routes from the north to the south through the California aquaduct. Since the worst drought that ever occured in California (1987-1992), Los Angeles and San Diego Water Departments have worked on reducing water demand. Demand side management has become a strategic dimension of their water supplies.
