Your Water Supply
Most of Montgomery County gets its water from the Washington Suburban Sanitary Commission (WSSC). Parts of northern Montgomery County bordering Frederick and Howard Counties, MD and Loudoun County, VA rely on individual wells.
WSSC takes water out of the Potomac River at an intake upstream of Great Falls. They also have two reservoirs on the Patuxent River, the Tridelphia and T. Howard Duckett reservoirs, which have a combined storage capacity of 10.2 billion gallons.
WSSC has two water treatment plants, the Potomac Water Filtration Plant and the Patuxent Water Filtration Plant, which can treat up to 285 and 70 mgd, respectively.
Address: Washington Suburban Sanitary Commission, 14501 Sweitzer Lane, Laurel, MD 20707
