WASH Alliance International (WAI) started its program in Bangladesh in 2011. This study calculated the amount of investment by other actors (i.e., households, the private sector, partners from non-development funding sources, and local government institutions) during 2016 that can be attributed directly to the program, and contributed to scale-up (leverage). It also analyzed the reasons for the key actors to invest in WASH and determined the catalytic effect of the program during 2011-2016 in creating additional WASH results.

Stichting Simavi commissioned, and a four (4) member team of Harmony conducted the study during March and April 2017. The team used Desk Research, Survey, FGD, In-depth Interview, Consultation, and Observation as data collection methods. The study location covered two (2) municipalities, and thirty-three (33) unions under six (6) districts, i.e., Bagerhat, Barguna, Laxmipur, Sirajganj, Satkhira, and Patuakhali.
