  1. Ministry of Water Resources Government of India Waste Water Recycling, Re-Use and Water Use Efficiency

  2. Water Resources in India

  3. 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 India’s Water – The Impending Crisis & The Challenge

  4. 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)

  5. 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%

  6. 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

  7. 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 QUALITY ASSESSMENT AUTHORITY

  8. 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. Water Conservation and Recharge

  9. Scope for Irrigated Agriculture withtreated Waste Water in India

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