WATER RESOURCES IN INDIA
INDIA’s WATER – THE IMPENDING CRISIS & THE
CHALLENGE
 Per Capita Water Availability
 1951:
5177 Cubic Meters per Annum
 2001: 1869 Cubic Meters per Annum
 2025: 1341 Cubic Meters per Annum
 2050: 1140 Cubic Meters per Annum

There is a rapid increase in demand for water
in various sectors
 2000
– 634 Cu.m per person
 2025 – 822 Cu.m per person
NATIONAL WATER MISSION
One of Eight Missions under National Action
Plan for Climate Change (NAPCC)
OBJECTIVE:
Conservation of water, minimizing wastage
and ensuring its more equitable distribution both
across and within States through integrated water
resources development and management.
Action: Formation of NBQUE (National Bureau of
Water Use Efficiency)
WATER USE EFFICIENCY (WUE):
Irrigation – accounts for about 80% of water use
WUE = Conveyance Efficiency (65-70%) x
On farm Application Efficiency (55-65%)
Surface Irrigation :
WUE ≈ 35-45%
Groundwater Irrigation: WUE ≈ 55-65%
DOMESTIC WATER SUPPLY
- Distribution loss ≈ 20% (Non-revenue water)
- Tremendous scope for saving in water use
INDUSTRIAL WATER SUPPLY
- Higher water footprint in industrial processes
- Emphasis on recycle & reuse of treated water
WATER QUALITY ASSESSMENT AUTHORITY



About 2.17 Lakh (villages) rural population affected
with water quality problems.
Developmental activities also have contributed
significant pollution load in freshwater systems.
Uniform Water Quality Monitoring Protocol notified and
Circulated to States & other agencies for adoption.


Directions have been issued to Constitute WQRC
(Water Quality Review Committee) & Finalise WQMP
(Water Quality Management Plan).
Areas identified for polluted River stretch and their
remediation.
WATER CONSERVATION AND RECHARGE

Appropriate practices for water conservation and
artificial recharge to ground water need to be
implemented
in
participatory
mode
involving
stakeholders.

The MoWR has prepared a draft master plan for artificial
recharge of ground water in different hydro-geological
terrains, and evolved area-specific feasible recharge
structures & their designs.
