The Hackensack Water Company developed water supply and storage in northeastern New Jersey during the latter part of 19th and in the 20th century, initially to provide service to the towns of North Hudson, and the cities of Hoboken and Hackensack using the watershed of the river from which it took its name, the Hackensack.[1] Originally its headquarters and major facilities were located in Weehawken, New Jersey . Remnants of its early infrastructure can be see at the Hackensack Water Company Complex and the New Milford Plant of the Hackensack Water Company.
