Optimization of the structure and parameters of the developing group water supply systems

Summary

Group water supply systems many of which are high-power and capital-intensive facilities have been widely practiced on the arid territories of Russia. In designing and developing these facilities substantiation of their structure and parameters has been the most important task. Based on flow-oriented models and optimization methods a method is proposed that provides for the solution of the following problems both as a whole and separately: optimization of the location and capacity of underground and surface water intake facilities; optimization of the location, capacity and composition of water treatment facilities; selection of the route of group pipelines and their optimal diameters; optimal distribution of the construction of new and upgrade of the existing network sections under the conditions of limited investments. The methodology of the optimal design is based on the comparison of cost, technical, reliability, ecological characteristics of the analyzed construction and operation options of group water supply systems. The main process parameters of the designed water supply systems are determined by their cost in the optimization criterion on the basis of which the best option for the future construction and operation of group water supply systems is chosen. Reliability, controllability, and aseismic strength are taken into account in terms of definite limitations of both technical parameters and investments into the construction and operation of group water supply systems. Based on the proposed method and designed program the substantiation of the structure and parameters of group water supply systems in the Irkutsk Region was developed.
