Directly drinkable water supplied to the inhabitants of any rural zone is met for the most part from the groundwater sources. A large number ofthe tubewells end up dry amid summer causing genuine water emergency. The Public Health Engineering Directorate (PHED) under Government of West Bengal decided to execute a scheme for withdrawing and delivering surface water from River Rupnarayan to supply drinkable water to the residents of Panskura- II block of East Medinipur district in West Bengal. In this study a command area zone of close piped network from the above mentioned scheme has been chosen. During the analysis, WaterGEMS software was used. The entire network system consists about 341 numbers of pipes and 289 numbers of junctions. The study is concentrated to develop a model of pipe network of Zone I of Panskura Block II under PHED water supply scheme based on WaterGEMS software, to determine the velocity and headlosses in pipes alongwith pressure at nodes in modeled system and to optimize the number and locations of airvalves in order to exhaust away the entrapped air in the pipelines due to geographical undulations. About twelve optimized air valves were suggested for the whole network.

Abstract


Directly drinkable water supplied to the inhabitants of any rural zone is met for the most part from the groundwater sources. A large number ofthe tubewells end up dry amid summer causing genuine water emergency. The Public Health Engineering Directorate (PHED) under Government of West Bengal decided to execute a scheme for withdrawing and delivering surface water from River Rupnarayan to supply drinkable water to the residents of Panskura- II block of East Medinipur district in West Bengal. In this study a command area zone of close piped network from the above mentioned scheme has been chosen. During the analysis, WaterGEMS software was used. The entire network system consists about 341 numbers of pipes and 289 numbers of junctions. The study is concentrated to develop a model of pipe network of Zone I of Panskura Block II under PHED water supply scheme based on WaterGEMS software, to determine the velocity and headlosses in pipes alongwith pressure at nodes in modeled system and to optimize the number and locations of airvalves in order to exhaust away the entrapped air in the pipelines due to geographical undulations.
