DEVELOPMENT AND HYDRAULIC ANALYSIS OF A PROPOSED DRINKING WATER DISTRIBUTION NETWORK USING WATERGEMS AND GIS

摘要

Safe and potable drinking water is a prerequisite for sustainable living. After achieving much success in distributing drinking water in cities and towns in India, rural areas have become a major concern by the state governments. In the present paper a sustainable, innovative, environmental friendly and cost effective water supply system for arsenic-affected water-stressed regions in Murshidabad District, West Bengal in India as proposed is analyzed using WaterGEMS software to study its dynamic behaviour in an Extended Period Simulation tool. The water supply network model was established using a GIS map obtained from the QuantumGIS software. The objective of this paper is to design safe drinking water networks through gravity cum pumping and hydraulic analysis of pipe networks using the WaterGEMS software for virtual-time realization of pressure head and average daily flows through the house connections and stand-posts. Hydraulic simulation has been carried out for a continuous supply of 24 hours daily to achieve the desired results with suggestive conclusions for practical implementations.
