The water supply system consists of 8 independent wells and 13 major water treatment plants which provide clean safe drinking water to 92,000 customers. The water treatment plants derive their supply from 57 production wells. The basic system is supplemented in the northern portion of the county by three connections to the City of Baltimore, from whom the County purchases water. The water system capacity of 37.5-million gallons per day (MGD) is adequate to meet the average daily demand. |
