The present invention discloses a method of demand management and control of a pipe network that is a computer-controlled fluid network and has a limited pressure head or gravity feed; the pipe network includes a plurality of outlet valves through which fluid may be delivered; the valve is automated to maintain a desired flow at the valve; the method comprises: maintaining a real-time database within the computer-controlled fluid network; and receiving, via the user interface, a request to deliver fluid from at least one of the valves, wherein the request comprises a flow rate, and time of delivery; the method further comprising: using predetermined parameters from the real-time database to determine if the network has a hydraulic capacity for delivering the delivery; and if the hydrauliccapacity is available, monitoring and controlling at least one of the plurality of valves and at least one another valve to communicate the delivery and maintain a desired flow between a predeterminedlimit and manage a pressure head within the fluid conduit network in an adjustable manner.
