A method for raising liquid from a reservoir to a tank positioned above the reservoir, the liquid being withdrawn from the tank at the same rate that it enters for further utilization. The method involves providing a pressure differential, in part by creating a sub-atmospheric pressure within the tank combined with pressure derived from a head of water above the water supply conduit pipe inlet, to cause the liquid to flow up a conduit connecting the tank and reservoir. The invention also relates to a system for carrying out the method.
