The Croton Aqueduct

Before it, New York drank from foul wells and watched fires burn for want of water. The Croton Aqueduct brought clean water 41 miles by gravity, and the city threw a party.

For two centuries New York drank bad water. The wells were foul, the Collect Pond was a sink of filth, cholera came back again and again, and when the Great Fire of 1835 destroyed much of lower Manhattan, the water was frozen and scarce and the city could only watch it burn. So New Yorkers voted, in 1835, to build something enormous: a 41-mile masonry aqueduct to carry clean water by gravity from a dammed river in Westchester, across the Harlem on the High Bridge, into reservoirs in Manhattan. The chief engineer, John B. Jervis, set the slope at thirteen inches to the mile so the water would flow the whole way on its own. When Croton water arrived in 1842, the city threw one of the largest celebrations in its history: a seven-mile parade, fountains shooting fifty feet into the air, and a song written for the day. Clean water did more to save New York lives than any doctor of the age.

  1. Song

    The official song of the day named the two enemies clean water had beaten: disease and fire.

    Water leaps as if delighted,

    While her conquered foes retire!

    Pale Contagion flies affrighted

    With the baffled demon Fire!

    George Pope Morris, "The Croton Ode," sung at the celebration, October 14, 1842

  2. Diary

    The city’s most quoted diarist, capturing the giddy public obsession in the days before the parade.

    Nothing is talked of or thought of in New York but Croton water; fountains, aqueducts, hydrants, and hose attract our attention and impede our progress through the streets.

  3. Diary

    The Great Fire destroyed hundreds of buildings in lower Manhattan while the hydrants and rivers were frozen. It is what finally pushed the city to build the aqueduct.

    How shall I record the events of last night, or how attempt to describe the most awful calamity which has ever visited these United States? ... my fancy filled with images of horror which my pen is inadequate to describe.

  4. Document

    It was treated as a civic triumph on the order of a national holiday. The temperance societies marched proudly: the engineer had banned liquor from the works.

    The Croton Water Celebration of October 14, 1842 ran some seven miles, with thousands of firefighters, militia, temperance societies, and trade unions marching from the Battery up Broadway and back to City Hall Park, where the new fountain shot Croton water about fifty feet into the air.

  5. Document

    Jervis was a self-taught Erie Canal veteran. His grade and his bridge made gravity do all the work.

    The chief engineer, John B. Jervis, set the aqueduct’s grade at thirteen inches per mile so the water would flow the entire 41 miles by gravity alone, and modeled the High Bridge across the Harlem River on the aqueducts of Rome.

  6. Document

    Clean, abundant water remade public health, firefighting, and the city’s capacity to grow.

    With reliable water came sewers, indoor plumbing, and street hydrants, and the death rate fell as cholera lost its breeding grounds. The city’s population passed a million, eventually outgrowing the aqueduct itself.
