1. A method for determining the amount of demand in a water distribution system having an input, a storage reservoir and an output, the method comprising the steps of:

  • measuring the volume of water flowing into the water distribution system through the input during a predetermined interval of time;

    measuring the change in the volume of water stored in the storage reservoir during the same time interval;

    measuring the volume of water flow exiting the water distribution system through the output during the same time interval;

    calculating an adjusted input measurement by subtracting the measured flow of water exiting the water distribution system from the measured volume of water flow into the water distribution system;

    adding a measured increase in the volume of the water in the storage reservoir to the adjusted input measurement, or subtracting a measured decrease in the volume of water in the storage reservoir from the adjusted input measurement, to determine the amount of demand upon the water distribution system; and

    providing the determined demand to at least one of a memory, a data storage location, and a data output.
