Application of effective technologies for the restoration of water transportation networks in the post-war period

Abstract

The hydraulic and technical and economic characteristics of water transportation networks using pipelines made of different materials were studied. Based on the results of the research, recommendations have been developed that allow utilities to determine the number and location of control units based on the results of determining nodal pressures, taking into account the material of pipelines when designing networks and reconstructing individual sections of them.

The relevance of the issue under consideration is explained by the fact that many Ukrainian utilities have faced major challenges the wartime. A sound approach to the construction, reconstruction, and modernization of water transportation networks will make a significant contribution to the restoration of urban infrastructure and reduce the dependence of utilities on external energy resources.

This paper analyzes changes in the hydraulic and technical and economic performance of the water supply network, taking into account the use of pipelines made of different materials for its construction and reconstruction. It is shown how the design pressure, capital and operating costs change when using pipelines made of cast iron, reinforced concrete, and polyethylene. The research results are presented in the form of a piezometric map, hydraulic and technical and economic indicators. The tasks to be solved by the flow distribution control system during the restoration and modernization of water transportation networks are defined.

Modeling of water supply networks schemes during their reconstruction and modernization, analysis of pressure zones in the network allows determining the required number of pressure control units and their locations, taking into account the need. A distinctive feature of this approach to flow distribution management is the timely prevention of emergency water losses and the selection of priority areas for network modernization. Recommendations on flow distribution management can be offered for implementation in the work of the dispatching service of the Zaporizhzhia utility company
