Approaches to the implementation of hydraulic electronic models of centralized water supply systems

. The analysis of the Russian normative and methodological documents, as well as research articles, has identified gaps in the development and practical implementation of hydraulic electronic models of existing water supply systems. The user guide of the software products, used to design these models, merely demonstrates the capabilities of software modules and misses the outcome of their application in certain cases. Decree No. 782 issued by the RF Government on September 5, 2013, being the document that regulates the development of electronic models of water supply systems, lists the requirements applied to software. The document, titled Construction regulations SP 31.13330.2012, has the requirements applicable to the hydraulic analysis of water supply system designs. This suggests that the Russian regulatory environment has no document that contains the basic requirements governing the development and detailing of hydraulic electronic models of water supply systems. This is an essential problem of urban utility networks, since the hydraulic electronic model is the basis for any further actions in strict accordance with which a development plan of a centralized urban water supply system is designed. Materials and methods. The article has a scientific review of the problem of design of electronic hydraulic models of centralized water supply systems and basic principles and approaches to electronic model generation. Results. The co-authors provide a detailed description of a methodology used to develop a model of urban water supply systems as well as the requirements set by foreign standards. Conclusions. Model development and calibration is structured in the article. This information is needed to adjust the characteristics of the designed model to a water supply system in operation.
