【 摘 要 】

The issue of water supply is one of the fundamental issues of the society, it is one of the pillars without which society would not work. The performance of the Targoviste water supply network has fallen over time, so solutions are being sought to optimize this network. A short description of the current situation has been made in the paper and solutions have been proposed for a certain area of capture and pumping of water to consumers. For the choice of pumps, water supply systems, calculations were made for the selection of system pipes, pumping height, pump motor power, and loss coefficients. With the help of the MODELICA calculation program, simulation of the pumping station was carried out using two separate calculation models by means of boundary conditions established with the help of water sources. The simulation of the water supply system was performed to verify that the pump power is sufficient to ensure the flow of water required by the consumer and to determine the operating mode of the drive system (continuous or intermittent).
