Sustainable drinking water management strategy using GIS Case study of Allahabad City (India)

摘要

Purpose - The purpose of this study is to develop a methodology for sustainable drinking water management by assessing the existing state of the water supply system in the study area (Allahabad, India). An attempt is made to identify various problems and gaps in the existing system and evolve solutions for the present water supply problems in a GIS framework. Finally, the paper proposes a conceptual framework for sustainable drinking water management. Design/methodology/approach - The study was conducted in four stages. The first stage involved collection of data and background information through various primary and secondary sources including reports and publications of various organizations. This was followed by discussions with various officials of Uttar Pradesh (UP) Jal Nigam (Water Corporation), Jal Sansthan (Water Board), State Ground Water Board, Central Ground Water Board and Municipal Corporation of the city. The second stage involved field studies in a few zones of the city. The third stage involved data input and analysis on a GIS platform, and the fourth stage includes the development of a solution of the present problems and proposing a conceptual framework for ensuring sustainable drinking water management for Allahabad City. Findings - ArcInfo 9.1 has been used as a tool for storing all types of relevant data for analysis and decision making. The various thematic maps include water supply zone map, water deficit localities map, land use map, location of tube wells, overhead tanks, zonal pumping station, ward boundaries, population map, water demand and supply map. Research limitations/implications - Applicability of a partnership between the public and the private sector has to be checked for proper institutional analysis in Allahabad City. Originality/value - The paper assesses the problems in the existing water supply system in Allahabad and proposes to give a GIS-based solution strategy for its sustainability. The proposed GIS-based conceptual framework would improve the current practice of drinking water management and would reduce the present problem of water crisis. The findings of the study would be useful for cities with similar problems in underdeveloped and developing countries.
