Hydraulic modeling of drinking water distribution network of South Dumdum municipality in West Bengal using epanet and watergems software

Abstract

The importance of water supply is acknowledged by all governments in developing countries who have and are giving priority to this provision. The presence of iron and fluoride in the ground water and the depleting level of the sub-surface water in the North 24 Parganas district has elevated a need to provide water for a community by tapping the most suitable source of water, i.e. surface water ensuring that it is safe for domestic consumption and then supplying it in adequate quantities. This paper concerns for the design of 24 X 7 urban water distribution systems at Ward No. 30 area consisting of 5.94 km of Pipeline and serving to a design population of 24871 within the South Dumdum Municipality in the North 24 Parganas district. This paper is helpful to have an insight for a comprehensive and diligent procedure for designing new distribution network in haphazard developed Municipality area. For designing of best economical hydraulic modeling of drinking water distribution system, EPANET & WaterGEMS software are used in this study. Design procedure satisfied all parameters namely residual nodal pressure, velocity of flow in pipe, pipe material, unit head-loss, reservoir level, peak factor and available commercial pipe diameters in adherence to the CPHEEO manual clauses. The results obtained show that the procedure makes it possible to ensure the norms as per the standard and minimum pressures when the peak water demand conditions is prevailing. Both the software’s EPANET & WaterGems yielded similar output. Keywords: EPANET, Water-GEMS, Urban, Water, Distribution, Hydraulic, Modeling
