  • 17. Slide 17 Household Water Security Tanka is key asset at household in desert region for storage of water, people do depend on common sources to refill - • Water sources to supplement requirement (e.g. tanker delivery, ponds, check dams) • Consumption (e.g. assess needs - drinking, household, livestock etc) • Handling of water to maintain quality at home, during transit through good protocols Tankers and Camel carts for fetching water in bulk for the kunds Baoris/ Talab (Open Lakes) as an alternate RWH storage system

  • 22. Slide 22 Mainstreaming…… • Government support and Microfinance holds the key for solving the drinking water problem • Mainstreaming through ongoing schemes like MGNREGA akin to TSC to fund • Promotion of rain water harvesting as adaptation measures – size optimization (variable factors - rainfall & family size) • Water security at household requires revival of common water storage structures like Pond, Talab, Naadi etc, which supplements the requirement once water stored in HH Kund exhaust
