  The District of Columbia Water and Sewer Authority, also known as WASA or D.C. Water, is an independent authority of the Washington, D.C., government that provides drinking water and wastewater collection in the city. WASA purchases water from the historic Washington Aqueduct, which is operated by the Army Corps of Engineers. The water, sourced from the Potomac River, is treated and stored in the city's Dalecarlia, Georgetown, and McMillan reservoirs. The aqueduct provides drinking water for a total of 1.1 million people in the district and Virginia, including Arlington, Falls Church, and a portion of Fairfax County.
  
  Pepco is the city's electric utility and services 793,000 customers in the district and suburban Maryland. An 1889 law prohibits overhead wires within much of the historic City of Washington. As a result, all power lines and telecommunication cables are located underground in downtown Washington, and traffic signals are placed at the edge of the street. The D.C. Public Service Commission approved a seven-year, $500 million plan in 2017 to bury more lines underground; construction started in 2019.
  
  Washington Gas is the city's natural gas utility and serves more than a million customers in the district and its suburbs.
