 El Dorado Hills Water Treatment Plant

El Dorado Hills water treatment plant processed 6 million gallons of water per day when EID took over its operation in early 1973. At that time, the facility
was in the middle of undeveloped land. Today, residences, a school, and a community park surround the plant. Its treatment capacity has been increased to 26 million gallons per day.
