The invention provides a method of delivery of fluid to at least one customer (114) through a computer controlled fluid network (100). The fluid network (100) has a plurality of regulators to control the flow of fluid along the fluid network (100) to deliver a predetermined amount of fluid to at least one customer (114). The network (100) includes a first control system (102) for opening and closing the regulators under computer control. The first control system (102) collects data based on timed measurements of fluid levels upstream and downstream of respective regulators and the opening positions of respective regulators, using data analysis to provide respective models for prediction of respective fluid levels between regulators. A second control system (104) that is a supervisory layer interacting with the first control system (102) to provide adjustments to the controlling of the regulators by the first control system (102) based on constraint and future flow load. A third control system interacting with the first (102) and second (104) control systems. The third control system (106) processing fluid delivery requests the at least one customer (114) to provide a flow load delivery schedule (118) based on the hydraulic capacity of the fluid network.
