Water Scarcity
Reasons of this
Overexploitation
Deteriorating Quality:
Adverse Effect of Economic Development
Hydroelectric Power
River Pollution
Need to conserve it
• To safeguard from health hazard
• To ensure food security
• To continue our livelihood
• To preserve the ecosystem
MULTI-PURPOSE RIVER PROJECTS AND INTEGRATED WATER
RESOURCES MANAGEMENT
Dams:
RAINWATER HARVESTING
• Roof top rain water is collected using a PVC pipe• Filtered using sand and bricks• Underground pipe takes water to sump for
immediate usage• Excess water from the sump is taken to the well• Water from the well recharges the underground• Take water from the well (later)
Harvesting System
Broadly rainwater can be harvested for two purposes
Storing rainwater for ready use in containers above or below ground
Charged into the soil for withdrawal later
(groundwater recharging)
A New Method For Water Conservation
• BAMBOO DRIP IRRIGATION SYSTEM
