The water supply system includes a pressurized water supply, an underground water supply conduit fluidly connected to the water supply, and at least one outlet valve fluidly connected to the conduit and projecting upwardly to the surface of the ground. The portable drinking fountain comprises coupling means for fluidly interconnecting with the outlet valve, a drinking fountain head comprising an elongate, closed-end tubular member having a plurality of spaced-apart apertures in the upper, axial walls thereof for providing a plurality of upwardly directed streams of water for drinking, and an upright tubular leg member fluidly interconnecting the drinking fountain head and the coupling means for supplying water to the fountain head and supporting the fountain head in a vertically spaced relation above the ground.
