To do so, UWNJ utilizes, among other facilities, the Woodcliff Lake Reservoir, which is located in Hillsdale and the Borough of Woodcliff Lake ('Woodcliff Lake'). One of the reservoir's structures is a dam across the Pascack Brook, which UWNJ's predecessor, Hackensack Water Company, constructed in 1904. The dam is traversed by Church Road, a private road owned by UWNJ that is subject to use easements held by Hillsdale and Woodcliff Lake."</ref>
