Olivenhain Tries Desalinating Groundwater

Construction starts this month on a $1.5 million test well to show whether desalinated groundwater could supplement the drinking water supply for 86,000 customers of the Olivenhain Municipal Water District. The district serves parts of Encinitas, Carlsbad, San Diego, San Marcos, Solana Beach and neighboring communities, and relies almost entirely on water imported from the Colorado River and Northern California. Like agencies throughout Southern California, it’s looking for ways to diversify its water supply.
