Sustainable urban water supply Bhubaneswar Odisha

Abstract

Water is a natural and economic resource, which is unique and irreplaceable. Huge sums of households in cities around the developing world do not have access the utmost basic human necessities– safe and consistent water supply. Water provision delivery in urban area of India is acknowledged by inadequate supplies, limited exposure of household connectivity, deteriorating infrastructure, environmental unsustainability of water and poor quality according to Government of India, World Bank reports and United Nations estimates. Water Sustainability signifies to the arrangements of environmental Sustainability and financial sustainability of water in an urban area. Appropriate setting of prices is obligatory to provide satisfactory water to increasing urban population of India. Most of the state’s water supplying units or urban-level water boards were running in loss, along with cover the loss could be demarcated as the gap among revenues from water usage and water delivery charges – from government grants and devaluation of wealth. A comparative analysis among various Indian cities is being carried out on the basis of water price and their pricing mechanism along with deficit it is found that Bhubaneswar city is the most affected one. The analysis comprises of plotting water accessibility and distributional aspect of water supply through GIS tools and techniques which will detail out the under-served and over-served ward, calculation cost revenue gap, evaluation of water pricing mechanism which will explain revenue deficit, Marginal plus Average cost pricing and IBT (Increasing Block Tariff) of water which will identify the effective and efficient pricing option. Along with it spatial analysis is being carried out with three spatial factor that are proximity, circle rate and building density which will classify the ward and support in providing spatiofiscal (amalgamation of spatial and financial value) measures. Proximity is deliberated as the distance from intake water plant to the water reservoir at ward level which is assisted through Inverse Distance Weighting analysis and Cost Distance tool. The analysis provides a rational policy framework for sustainable urban water supply that spells out spatio-fiscal measures, key areas of reform, equitable and efficient water pricing possibility. In addition a systematic phase is developed in the shape of Application and website which enhance towards transparent, reasonable, safe and digital India.
