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. 

Providing service on a 24/7 basis, the utility is managed by 170 people, including engineers, scientists, licensed operators, mechanics, electricians, instrument specialist, business professionals and support staff, who protect public health, safeguard the environment, and support economic development.

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 to:
- 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.

The Division operates as an enterprise fund, which means we are fully funded by user fees and charges. We are not supported by any tax revenues, including property taxes. Revenue is solely generated by user charges, licensing and permitting fees, and interest on investments. 
Drinking Water

Our dedicated professionals operate three drinking water facilities, which treat an average of 17 million gallons of water a day, ensuring residents and businesses have reliable access to clean, safe drinking water.  Our assets include nearly 700 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 more than 788 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.
