The purpose of the study was to present the principles of creating and implementing an integrated water and wastewater management system based on hydrodynamic modeling of water distribution and sewerage disposal systems in small and medium-sized municipal enterprises. The computer modeling of water and sewerage networks is an efficient tool for finding the causes of increased costs of operation of these plants. The simulations carried out in modeling programs enable to quickly find the optimal variant to solve the problem of exploitation or economically effective direction of their modernization. Geospatial data (GIS) is being increasingly often being used to optimally manage the municipial water and sewerage infrastructure. This gives an additional analytical tool for planning, designing, obtaining operational data, etc. The integration of hydraulic models of the water supply and living and economic networks into one coherent management system is possible, owing to which, a holistic assessment of the functioning of the water and sewerage management system in the city is possible. The decision support systems based on the spatial information system (GIS) associated with various specialized software, are becoming the standard of modern management of a water and sewerage company. To date, only about 40% of enterprises in this industry in Poland have used systems of this type. In addition, most of the GIS-based management systems used in practice are limited to an inventory of existing network resources and integration of many databases in one coherent IT system. Only in a few cases, the systems of this type contain modules modeling the network operation under dynamic conditions, which results primarily from additional implementation costs related to the construction of sufficiently reliable models of the water supply and / or sewerage network. The implementation of the proposed solution includes: construction of a water supply network simulation system, construction of a domestic and economic sewerage system simulation system, devising scenarios for system operation under the conditions of city development and climate change, multi-criteria assessment of the economic effectiveness of systems operation taking into account social and environmental criteria, development of an integrated management system the system, taking into account the guidelines for increasing the effectiveness of its operation and work safety.
