Village Women use Science and Technology Lab - 2 - Land Concept
Why women?
-Agents of change, they influence decisions at home and at the Panchayat
-Water at home is managed by the women
-Girl child is often pulled out of school to ferry water from distant sources
•An ‘All Girls’ team
•Brainstorming Session
•Identify water related issues

Do’s & Dont’s
Clean-roofs and terraces
Provide adequate storage systems
Pollution free storage systems
X Store—insecticides, rusting iron, manure, detergents
X Use Pets on terrace
X Use chemically polluted water to charge ground water
USEFUL tip : Guppy fish for mosquito control
Scaling the Project
• 2002: Made the school ‘Water Literate’
• 2003: – Installed prototype
– Designed promotional literature
• 2004:– Establish the ‘ Rainwater Resource Center’
– Plan to set up 100 units in 10 villages
• 2005:– Scaling it to 10,000 Households
– Creating global awareness on management of natural resources
