Water supply and distribution networks consist of large numbers of interconnecting pipes with occasional control valves, all of which have non-linear relationships between flow and head loss. Reservoirs are connected at strategic points throughout the network to provide storage capability and maintain required pressure levels for the consumer demands. In many regions boreholes are a typical source of water supply with pumping to the network via pumping stations using parallel combinations of fixed and/or variable speed pumps. Booster pumps together with control valves are normally used for transfer of water between reservoirs of differing pressure zones. In both cases the pumping flows are dependent upon the reservoir levels and the costs upon electricity unit and demand charges. Since water networks contain storage the optimisation problem reduces to minimisation of electricity chagres and associated costs for the complete network over the entire control period. This can be achieved by control of pumping and storage whilst catering for consumer demands and maintaining desired reservoir levels. Consequently the successful application of optimisation methods depends significantly upon the formulation of a dynamic network model for rapid and repeated evaluation of the effects of control strategies upon the network operation. In addition a prediction scheme is required which will estimate consumer demands throughout the control period.
