Multipurpose use of water resourcesMultipurpose use of water resourcesAffordable and convenient piped water supply technology◦ Skilled development training on different income-
generation activities (IGAs) for raising household incomes supported by RDA-credit.
◦ Private operators ability to repay investment costs over 10 years
Increased irrigation coverage & Productive Use◦ Efficient and economic use of water resources through
buried pipe irrigation.◦ Year round water supply in productive use along with

Duel use of DTW (1st in Bangladesh) by RDA-Shasibadoni village
118 schemes Completed between 1999 to 2008
Operators : 30 % individuals20% Cooperatives50 %NGOs
Price of water : 1.2 U$/Household/month ; 72 U$ /Hectare/irrigation/per rice crop
Lessons LearnedOwnership must be clear from the startEfficient design and selection of community very important100 % O&M is recoveredMore household is possible to connect with the help of RDA credit (Microcredit) operationClose monitoring of schemes by public sector is key to recovering capital costs
Private operators are keen to pay down payment (10% for capital 3.000U$)
Main MessagesMultipurpose use of water is one of the best ways to make PPP profitable and sustainableIncome generation activity training and micro credit are key for sustainability
More household is possible to connect with the help of RDA credit (Microcredit) operation
