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, who reside outside of the three incorporated towns of Bel Air, Aberdeen, and Havre de Grace.

Our mission is to protect public health and the natural environment while sustaining economic growth within the County by providing a safe and reliable supply of water and public sewerage services through cost effective management and maintenance of our infrastructure while meeting the challenges of continual growth within County.

Our goals are to provide clean and affordable water to our customers while being responsive, timely, and economical in management and service.

The Division operates as an enterprise fund, which means we are fully funded by user fees and charges. We are not supported by tax revues, 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 pipes, 12 storage tanks, and 12 booster stations.  

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 waste from homes and  businesses to be treated at one of our three wastewater treatment plants before it is returned to the waterway.
