  1. 1. An approach to Safe, Affordable Drinking Water for water scarcity regions Rain Water Harvesting 19th February, 2013
  2. 2. It is daily chore for women in scarcity areas, who walk miles for hours for water!Confidential 2
  3. 3. Transported as well……Confidential 3
  4. 4. Options - open Bawari, Wells/hand pumps/ PWS Access is the key challenge beside the qualityConfidential 4
  5. 5. Key contaminants : fluoride in ground water or microbial in surface! Bacteria 17% Chemical 83%Confidential 5
  6. 6. Western region of country worst affected by both Chemical & microbial contamination Open ponds contaminated Ground water very deep & saline forcing rain water as viable option Hydro-geothermo regimeConfidential 6
  7. 7. Traditionally people have adopted……… Tankas Bawari (Pond)Confidential 7
  8. 8. • HH structures found most appropriate• Affordability ?• No institutional mechanism to support
  9. 9. Rain Water Harvesting – a case for water credit Objective: Develop and implement improved approaches to rainwater harvesting throughconstruction optimization, quality assurance and new funding products for sustainability and scale-up Status  Installed ~ 970 household and 40 community kunds in 55 villages  Kunds to provide potable water to ~16,750 villagers  Completed construction / design Members of household with newly Safe Water Network site visit working on improvements constructed kund design improvements with partners  Implemented financial product for households  Introduced quality assurance program Community mobilization Quality assurance, health Quality assurance and Microfinance funding Engineering & design and construction policy whitepolicy impacts & paper productConfidential 9

  11. 11. Microfinance ProductProducts JL10 (Cistern 1000 L capacity) JL15 (Cistern 1500 L capacity)Loan Amount Rs 10,000 Rs 15,0000Repayment Period 24 months 36 monthsRepayment mode Equated MonthlyService charge SHG 12% perMonthly Installment Rs 500Delivery of product Only through SHG, SHG GuaranteeRepayment Starts After 1 month construction of tank or 2 months of availing credit, whichever is earlierPenalty No prepayment penalty SHG will decide the penalty for missed installments
  12. 12. Rainwater Harvesting Operations • 1016 Tanka (Cistern) & access to 16732 • Recovery 52% • Provides water security • 580 Tanka made by other donors (secondary impact) • RWH Tanka partially meet water needs but solves for water securityConfidential 12

  15. 15. Users views “This is a gift from heaven. I no longer need to carry water 5 hours each day and have more time to earn money” - Below Poverty Line widow who constructed the kund through a loanConfidential 15
  16. 16. Household Water SecurityTanka (Cistern) is the key asset at household for storage of water, people do depend on common sources -(i) water resource to supplement requirement (e.g. tanker delivery, ponds, check dams)(ii) consumption (e.g. assess needs - drinking, household, livestock etc)(iii) Ensuring water quality at home, during transit through good protocols Tankers and Camel carts for Baoris/ Talab (Open Lakes) as an fetching water in bulk for the alternate RWH storage system kundsConfidential 16
  17. 17. Mainstreaming…… • Government support and Microfinance seems to hold the key for solving the drinking water problem • Financial institutions can play crucial role by providing credit to people through Self Help Groups to construct RWHS • Mainstreaming through ongoing schemes like MGNREGA akin to TSC to fund RWH • Gujarat has demonstrated the approach to support through programmatic intervention with partial financial support to BPL & APL families • Water security at household requires revival of common water storage structures like pond, Talab, Naadi etc, which supplement the requirement once water stored in HH Kund exhaustConfidential 17
