Abstract: A device prevents water from leaking into a manhole. The device includes a body having first and second portions that are integrally formed. The first portion extends along and above a periphery of the opening of the manhole and the second portion extends upwardly from the first portion and provides access to the opening of the manhole. Preferably, the first portion includes a downwardly extending lip disposed along an outer vertical surface of the manhole. In addition, a cap is positionable on the second portion to prevent water entering the manhole from the manhole's opening.
