Access to finance is a main obstacle to promotion of rainwater harvesting for households, and is important so that users can replicate the technology – however, so far there are few examples on a global level with micro-credit for rainwater harvesting. An initiative is underway in Nepal to trial the promotion of rainwater harvesting tanks through a combination of subsidy and credit from micro-finance institutions (MFIs), mainly targeting women, where gradually over time the subsidy will be replaced by credit completely where rainwater harvesting systems will hopefully be one of the credit products for MFIs. Lessons learned from micro-credit for biogas plants in Nepal show that the system can work when initially mixed with government subsidy – total repayment period ranges from 5 – 7 years and interest rates vary between 11.5 – 16%.

|'''Akvo RSR Project:''' [http://rsr.akvo.org/project/107/ Rainwater harvesting in Guinee Bissau]
The project will take place in Tombali in southern Guinee-Bissau. The aim is to build 50 domestic rainwater harvesting tanks of 5000 l each and to train 10 masons. This is a part of our overall program in 2009 making 170 tanks and training 35 masons in constructing and maintaining watertanks and latrines.
50 tanks will serve 50 households of 16 members each during the dry season March, April, May and June. The result will reduce the burden of women, carry water over a distance of 2 - 4 km daily.
