Total Precipitation : 4000 BCM
Total Water Availability : 1869 BCM
Total Utilizable Water : 1122 BCM Surface Water - 690 Ground Water - 432
ANTICIPATED DEMAND (BCM)
In 2010 : 813 710*
In 2025 : 1093 843*
In 2050 : 1447 1180 *

* With improved management
WATER MANAGEMENT ISSUES
• Non-availability of Resource• Sustainability Issues• Inefficient use• Contamination• Climate Change?
WATER MANAGEMENT ISSUES – RURAL AREAS
• Low penetration of protected water supply schemes• 30% rural Indian lack access to safe drinking water
supplies• Only 7 States have rural areas with full drinking water
supply.
• Sustainability Issues (‘Slipped back’ habitations)
• Neglect of traditional water management practices
• O & M Issues ( Lack of technical expertise ??)• Contamination (natural/man-made, poor
sanitation)• Inefficient use of available resources.
SUSTAINABLE WATER MANAGEMENT- OPTIONS ???
• Supply Side• New Sources & Technologies • Recharge Augmentation (RWH, Water
Conservation)• Better sanitation
• Demand Side• Improved water use efficiency• Incentives / Regulation
• IEC• Awareness creation• Capacity building of grass-root level stakeholders
ENERGY
Indian Energy Scenario
• Over 40% households do not have electricity.
• Nearly 1/3rd of our energy is still from non-commercial sources (biomass).
• Per capita energy consumption is third and per capita electricity consumption is fifth of the world average.
• India faces an enormous demand supply gap of about 11% energy shortage and 14% peak power shortage.
Options ??
• Renewable energy sources • Solar (Photovoltaic /Thermal)• Wind• Tidal• Geothermal• Biomass• Small Hydroelectric schemes• Bio-fuels
• Improvement in Energy Efficiency• Improved Storage Technologies• Awareness creation / Capacity building
WASTE MANAGEMENT
INDIAN SCENARIO
• Over 50 Million Tonnes of Municipal Solid Waste (MSW) generated per annum.
• Per-capita waste generation increasing @ 1.3% & total waste generation @ 5% per annum
• Open Dumping is common – No scientific closure of Landfills - Health impact, GHG emissions etc.
• Little work done on scientific waste management – waste minimization, reuse, recycling.
• Suburban & rural areas worst affected!
POSSIBLE APPROACHES• Waste Management
• Minimization• Segregation• Recycling• Processing (Resource Recovery)• Transformation• Sanitary Land fills
• Method to be• Technically sound & Financially viable• Environment-friendly• Easy to operate & maintain ( by local communities)• Decentralized ( Processing at source – to the extent
feasible)• Sustainable & acceptable to the local community.
