The water system is comprised of approximately 480 miles of water main, 21 groundwater wells, seven pump stations, 10 reservoirs with a storage capacity of 49 million gallons, four pressure regulating stations, and seven connection points to the Metropolitan Water District. The system has an average daily demand of 30 million gallons from its roughly 45,000 service connections. Due to the age of the existing Well 32 infrastructure and equipment, constructed in 1985, the well's capacity to produce water has been significantly reduced. While the well is 38 years old, it is considered one of the City's newer wells and it still can be brought back to efficient service. The proposed rehabilitation project will ensure that the City of Santa Ana can continue to provide safe drinking water and meet the demands of the Santa Ana community.
