A water dispensing assembly is provided that is adapted to connect to a fire hydrant water outlet, the fire hydrant being connected to a water supply, for safely dispensing clean water for filling water bottles and the like. The water dispensing assembly is a self-contained unit that is relatively compact and low maintenance. The water dispensing assembly can be housed in an enclosed box-like housing structure that is tamper proof so that it cannot be accessed or modified by the public at large.
