The Emergency & Carryover Storage Project (E&CSP) in San Diego is one of the most important infrastructure projects constructed in the United States in the last century. In the naturally dry and arid regions of southern California, 80 percent of the water is imported from hundreds of miles away from more abundant resources in Northern California and the Colorado River.  This leaves all of southern California, especially the San Diego region, susceptible to disruptions in the water delivery system, namely from earthquakes, statewide system failures, or extreme droughts and other water shortages.
