DC Water Infrastructure
Where Your Water Comes From -- and Goes
The water you drink here starts in the Potomac River at Great Falls, where the Washington Aqueduct -- a federal agency -- collects 180 million gallons a day. DC Water buys treated water from the Aqueduct, then sends it to you through five pumping stations, 11 storage facilities, 1,300 miles of water mains and 42,000 valves.
The water you flush travels even farther, as DC Water handles sewer and wastewater treatment for about two million local residents, sending it through 1,800 miles of sewers and several pumping stations -- including the one in front of you now -- before arriving at the Blue Plains Advanced Wastewater Treatment Plant.
