ABSTRACT:
Method and apparatus for optimum distribution of water supplied to consumers is disclosed.
At selected nodes of a network from which water is supplied to consumers, the actual water consumption is measured to detect a standard pattern for water demand in each selected area. Next, predicted demand patterns for each and every node are determined by comparing the characteristics or attributes of each area with those of areas having standard demand patterns. Thirdly, manipulated variables of pumps and valves installed in the pipeline network are controlled on the basis of predicted demand patterns.
