Dams and Reservoirs

Three dams in the WSSC Water service area provide drinking water to our 1.9 million customers in Prince George’s County and Montgomery County. These include the Brighton Dam and T. Howard Duckett dams , which span the Patuxent River and create the Triadelphia and T. Howard Duckett reservoirs. WSSC Water also owns and operates the Little Seneca Dam.

Water Storage Tanks

Above-ground water storage tanks are an important part of WSSC Water's distribution system. The stored water supplements the water distribution system during times of peak water demand, such as in the morning when many of us are preparing for work and school. Storage tanks also provide reserve capacity to meet water needs during emergencies such as fires, power outages, pipeline breaks and other incidents.
