Abstract

Most conurbations are served by complex, multi-source water supply systems. Operating strategies for these systems often use control curves which advocate sudden changes in releases when storage falls. The paper describes the development of a new constraint based method of operating water supply systems which employs a hierarchy whereby the cheapest supply sources are considered first and then consideration passes to the more expensive sources until demand is satisfied. If the method produces an unsatisfactory solution at the first attempt, a relaxation technique is used and this is applied successively until all demands are met and no constraints are violated. To ensure relevance, the technique has been applied to the South East Wales Conjunctive Resource System. A comparison between the current control curve based techniques and the new technique is presented which shows the advantages of the new method.
