Between 2006 and 2015, the BRAC WASH programme in Bangladesh has helped over 39 million people gain access to hygienic latrines and 2.3 million people gain access to safe water across 250 sub-districts. It has helped to bring about a social transformation in areas where it works, with significant progress on rural sanitation particularly for the poorest families. Success has been achieved over a nine year period not only in the provision of hygienic household latrines, but in their use by all members of the family, and to a lesser extent in good hygiene practices such as handwashing.
