If the natural water supply doesn’t meet the water needs of an increased population, Marin is going to have to revisit the idea of building a desalination plant. Currently, the largest U.S. desalination plant in San Diego produces 50 million gallons daily at a cost of one cent per gallon. That cost is kept low given the San Diego’s plant is adjacent to a power station. If Marin had to draw its power from MCE or Pacific Gas and Electric Co., the cost would rise to 1.33 cents per gallon or $10 per billing unit over and above normal water charges.
