Dynamic model of the water distribution system as an analysis tool in the management of the Łapy water supply network

The subject of this paper is the analysis of a very common problem of water distribution systems of cities in Poland, which is the concentration of chlorine in water supply networks and the economic aspects of electricity consumption for the supply of pumps. As an example of the analysis, the water distribution system model of Łapy and the available data from the years 2015-2017 was used. As part of the work, an assessment of the existing state of the city water distribution system of Łapy was presented (lying in the Bialystok poviat), conducted with the help of the EPANET computer program, and aimed at improving the efficiency of the examined network. This allowed us to avoid errors during the investment and to assess the condition of the water supply network. This program was chosen because it is publicly available, as well as used by many companies to solve problems with water supply systems in a friendly and clear way.
