Justification of the parameters of developing water supply and sanitation systems based on their electronic models

Abstract

Most of the water supply and sanitation systems of modern cities and populated areas of the Russian Federation are characterized by significant physical depreciation, which is estimated at 60%., Significant moral depreciation, since some structures and pipelines are almost a hundred years old or more. At the same time, the replacement of old equipment is carried out annually at a rate of 2%. Such unsatisfactory rates of renovation are due to the lack of adequate funding and their irrational allocation to the construction of new ones, reconstruction and development of existing pipelines and structures. Obviously, to solve this problem, new and integrated approaches, new technologies for the design, construction and operation of water supply and sanitation systems are needed. One of such approaches is proposed in the work, based on digital technologies using electronic models of water supply and sanitation systems, on the basis of which methods for modeling operating modes and optimization methods for design solutions for the development of networks and structures have been developed. The results of applying the proposed technology on the example of water supply and sanitation in the city of Nizhneudinsk, Irkutsk region.
