Water Scarcity in Delhi:

Water Scarcity in Delhi

PowerPoint Presentation:

India has one of the fastest urbanization rates in the world. In terms of population, New Delhi is India’s second largest city at 11 million people. Its urbanization rate was the fastest in the world at 4.1% according to the 2011 census.

This rapid growth in urban population has placed an immense amount of pressure on existing civic services, including the provision of drinking water. The present demand for water (800MGD) now exceeds total availability from local sources (650MGD). To close this gap, water is being extracted from the ground via wells and hand pumps and is being trucked in from sources in other parts of India. :

This rapid development has also been a major cause of ground water depletion and surface water pollution in Delhi. :

As the urban population continues to grow, so does the city. As more roads, pavements, and buildings are constructed, the permeability of the ground decreases, thus diminishing the recharge of ground water. Though increasing demand requires the withdrawal of groundwater, this diminishing recharge means that the water table is falling steadily – by as much as 10 meters in the past decade. Not only does this not bode well in terms of water quantity, but it also increases the salinity of the groundwater, making it unfit for human consumption.

An increase in paved roads reduces the permeability of ground, resulting in pools standing water.

This patch of land used to be a water reservoir in the informal settlement of Aya Nagar. The reservoir is now dried up and is used as a landfill for waste disposal.
