Feasible Study for Allocation of Nodal Demands Through WaterGEMS

Abstract

Demand for potable water is an increase on continual basis with a corresponding increase in population and livelihood activities. The ever increasing demand can be fulfilled by designing efficient water distribution networks based on advance computing systems include modern hydraulic modeling and designing softwares, such as WaterGEMS, EPANET, LOOP, WaterCAD, InfoWater and KY pipes. The above-said softwares can stimulate real networks under the given circumstances independent of its size. Besides, these hydraulics simulation softwares yield results precisely and accurately within a considerable time. In parallel, one should emphasize on the relevant method for assigning the base demands through various methods, even though the difference is too low but still, it is important where precision becomes first criteria for designing a pipeline network. In this paper, authors highlight a comparative study about the hydraulic analysis outputs of pipeline network between different base demand allocation methods using WaterGEMS software with the main motive to model a feasible pipeline of water distribution network based on appropriate methods using demand control center for Bodhan town. The present system of distribution for Bodhan (study area) is adopted with an intermittent supply with the distribution network of total length of 89 km. Keeping in view of increasing population and changing demands of living beings, existing network has to be investigated for its steadiness for supplying water. Therefore, analysis was carried by simulating existing water network through WaterGEMS software. The examination was carried out based on inputs assigned to objects present in the network such as nodes, pipes and tanks. Design of network using simulation for assumed design period will make the municipality be aware of the changes in rate of increase in the demands, its validity based on pressure and other parameters. From the comparative results, the feasible method of base demand allocation is adopted for the design of water distribution network.
