| The aim of this work is to present the possibilities of improving the flow velocity of water in pipes in selected water distribution system. The analysis was based on the hydraulic model prepared using EPANET application.The water distribution system is supplied with water from two treatment plants. Pipes’ length of the tested network is about 87 km. Pipes diameters on the network are in the range 90 –200 mm, while the connections 25 –63 mm.Numerical simulations for the real conditions of the network showed the presence of a very low water flow velocity (below 0.5 m/s) in the most pipes. The low value of flow rate at the hour of maximum water consumption also causes an increase of the retention time of water in the network which may result in secondary pollution of water. In this work, several simulation were performed for differe nt variants of the numerical model.The increase of flow velocity in the pipes were achieved by closing appropriate valves, adding new pipelines and changing existing piping diameters, as well as through the implementation of cooperation of both pumping stations. Suggested solutions can also improve water quality parameters, as well as increase the reliability of the entire water distribution network. |
