The Division of Water & Sewer is responsible for the operation, maintenance, administration, planning and engineering of the public water and sewer facilities that service over 130,000 citizens of Harford County.  Founded in 1956 as the Harford County Metropolitan Commission, the utility has been rendering exceptional service for 60 years. 

Our mission is to provide our customers with safe, reliable water and sewer services in a responsive and cost effective manner; to protect public health and the environment; and to administer well-planned improvements to support community opportunities. 

We aspire 
- provide trusted and valued water and sewer services to our customers, 
- stand as role models, recognized as the environmental stewards of our community, and
- continue to be innovators, helping to drive opportunity within the County.  

Drinking Water

Our dedicated professionals operate three drinking water facilities, which treat an average of 14 million gallons of water a day, ensuring residents and businesses have reliable access to clean, safe drinking water.  Our assets include nearly 800 miles of water mains and laterals, 12 storage tanks, 12 booster stations, and 4,000 fire hydrants.  


Wastewater Management

Water that goes down the drain from taking a shower, washing dishes, using a washing machine, or flushing a toilet is known as wastewater.  Managing the County’s wastewater includes the upkeep of nearly 800 miles of sewer mains and laterals that carry wastewater from homes and businesses to be treated at one of our three wastewater treatment plants before it is returned to the waterway.
