Comprehensive optimization of water supply and sanitation systems

Abstract

Annotation. Because of the uneven distribution of water resources across the territory of our country, many localities and even cities do not have their own sources of water supply and reservoirs where it would be possible to discharge treated wastewater. To solve this problem, group and district water supply and sanitation systems are being designed, built and developed. The length of such systems is hundreds or even thousands of kilometers, and they include many pumping stations, regulating tanks, storage ponds, local and centralized treatment facilities. Significant financial investments are required annually for the construction and operation of such structures [1-6]. Therefore, the choice of routes, structure of structures, ways of transporting water and waste water, justification of the location of water intakes, treatment facilities are relevant and require special attention and technical and economic analysis of design options. The paper proposes a comprehensive approach to optimizing the structure of structures and methods for supplying water to consumers and transporting waste water to treatment facilities on the basis of the redundant design methods.
