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

National Water Mission
One of Eight Missions under National Action Plan
for Climate Change (NAPCC) OBJECTIVE Conservati
on 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.

8
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.

Scope for Irrigated Agriculture withtreated
Waste Water in India
Scenario Volume of waste water (M cubic m) Est. irrigated area (ha)
Using 75 of the treated Waste Water 1,070 130,000
Treating 50 of collected Waste Water 4,850 600,000

Area of Emphasis

• Basin Planning Approach for Water Quality
  Management.
• River Aquifer interaction.
• Minimum Environmental Flow of Rivers.
• Land-use pattern and regulation by States.
