Abstract: The pumping stations of the main water pipelines for the settlements provide the possibility of operation as a mini hydroelectric power plant (HEPP) when water consumption is low. Thus, part of the kinetic energy m(V12-V22)/2 of the water supplied to the buffer tank is utilized, and the produced electricity is provided to the Municipality for the needs of street lighting. When large quantities of water are delivered during the day, the hydro unit works as a pumping station, with electricity supplied by the municipal PV power plant.
