Water –The India Story

Global Freshwater Scenario

Global Freshwater reserves are rapidly depleting and this is expected to significantly impact many densely populated areas of the world

Low to middle income developing regions as well as highly developed countries will face water stress in the future, unless existing water reserves are managed effectively

• Although low and middle income developing countries currently have low per capita water consumption, rapid growth in population and inefficient use of water across sectors is expected to lead to a water shortage in the future

• Developed countries traditionally have high per capita water consumption and need to focus on reducing their consumption through improved water management techniques and practices

By 2025, India, China and select countries in Europe and Africa will face water scarcity if adequate and sustainable water management initiatives are not implemented

Freshwater Situation in India

Traditionally, India has been well endowed with large Freshwater reserves, but the increasing population and overexploitation of surface and groundwater over the past few decades has resulted in water scarcity in some regions

Growth of the Indian economy is driving increased water usage across sectors. Wastewater is increasing significantly and in the absence of proper measures for treatment and management, the existing Freshwater reserves are being polluted

Increased urbanization is driving an increase in per capita water consumption in towns and cities. Urbanization is also driving a change in consumption patterns and increased demand for water-intensive agricultural crops and industrial products



Total global water reserves is ~1400 MM Tr liters, of which Freshwater consists of only about 35 MM Tr liters

Groundwater and surface water, which together constitute 30.5%of the Freshwater reserves (~0.76% of the total water on the planet), are the most easily accessible and used sources of water

Every year, 0.11 MM Tr liters of precipitation falls on land

• 92% of this is lost due to surface runoff, evaporation, etc.

By 2025, an estimated 3 Bn people will be living below the water stress threshold

• Between 1995–2025, global population and per capita water consumption are projected to grow at a CAGR5 of 1.16% and 0.67% respectively

• Densely populated and developing regions of the world, such as Asia and Africa are expected to face the maximum water stress
