Design of a Pumping Main Considering Pipeline Failure

Cost and reliability are two diametrically opposite objectives in a pumping main design as the objective of an uninterrupted supply of water will increase the system cost. In this investigation, a methodology for pumping main design is presented by considering the costs of pumping main and pipeline breakage. Although it has been found that there is no clear-cut optimum point in such a design objective, there is however, a set of non-dominated points called Pareto-optimal front which can be used to optimize pipe diameter. It is hoped that this methodology will be useful to design engineers engaged in the design of pumping mains and will also result in the cost savings to water service providers.
