Abstract: | Urban and regional demand for freshwater in National Capital Territory of Delhi has grown significantly over the last few
decades. The National Capital Territory, Delhi is one of the most rapidly growing urban centers of the world, with a population
of about 15 million people, a high rate of immigration and numerous illegal settlements. In order to meet the increasing water
demand, the government is focused almost exclusively on supply management and engineering solutions, which have resulted in
investments of hundreds of millions of Rupees. Environmental, economic and social policies associated with water management
are largely inadequate and insufficient, which is resulting in increasing deterioration in the environment, health and socio-economic
conditions of a population living in one of the largest urban agglomerations of the world. Surprisingly, however, no long-term
strategies on demand-management, reuse, conservation, and improved water-management practices have been developed so far.
The aim of this paper is to provide an overview of the urban water use with a view to enhance the understanding of the factors
influencing urban water demand for residential, commercial and industrial sectors in National Capital Territory of Delhi.
The analysis indicates an urgent need to radically improve the current water supply and wastewater management practices to
become sustainable. Other measures such as public education and information/awareness will be necessary to achieve desired
rationalization in water consumption, especially in the residential and commercial sectors. |
