Washington Aqueduct

United States historic place

About

The Washington Aqueduct is an aqueduct that brings water from the Potomac River to Washington, D.C., and parts of its suburbs.

One of the first major aqueduct projects in the United States, it was commissioned by the U.S. Congress in 1852, and construction began the following year under the supervision of Montgomery C. Meigs and the U.S. Army Corps of Engineers. Portions of the aqueduct began operation on January 3, 1859, and the full pipeline began operating in 1864. It has been in continuous use ever since.
