Abstract

National Capital Territory (NCT) of Delhi is experiencing rapid urbanization for the last few decades. The area is lagging behind in water and waste management infrastructure. This is due to the fact that Delhi is recording high growth rate of population mostly through in-migration over the year which is taxing much upon the existing water resources and the provisions made for water supply. Consequently demand is higher than supply of the safe drinking water. The consumption of unsafe drinking water is therefore increasing and is causing serious health problems among the fellow residents of NCT of Delhi. These health problems are basically related to the digestive as well as excretory systems of the human body. These disorders are promoting mortality particularly among those segments of population which do not have access to potable drinking water. This paper is therefore a modest attempt towards examining the population growth rate and the scenarios of demand and supply for potable water as well as the overall water related intestinal infections and related mortality at present and their future occurrence. This requires synergy between the different sectors of the state to overcome the problem. of intestinal infection diseases in the region.

Highlights

  • A range of water problems including water shortage and defilement, unsustainable utilization of groundwater, ecological degradation and the risk of environmental change are being faced all around the world (WWAP, 2015; Morrison, et al 2009)

  • Increasing urban population, rapid population growth, poor urban water management, diverse use of water at a higher rate, dwindling sources of freshwater supply, poor and ageing water infrastructure, intermittently poor quality water supply and low water tariffs, all have combined to manage urban water supply a difficult goal to be achieved as the result of which the related rate of deaths is increasing in the National Capital Territory (NCT) of Delhi

Summary

Introduction

A range of water problems including water shortage and defilement, unsustainable utilization of groundwater, ecological degradation and the risk of environmental change are being faced all around the world (WWAP, 2015; Morrison, et al 2009). About 2.6 million people are dying each year due to water-related diseases and 2.1 millions mostly children below the five years of age die from diarrhoea (WHO/UNICEF, 2013; Edition, 2011). This indicates that there is a significant relationship between drinking water quality and human health. Surface water pollution has a significant impact on human health and on human life
