WaterAid has been operating in Bangladesh since 1986 as one of the lead actors in Water, Sanitation and Hygiene (WASH) sector and is well experienced in innovating, scaling up and managing large scale projects targeting poor and extreme poor. It has been registered with NGO Affairs Bureau in 1996. The geographic focus of WaterAid Bangladesh includes urban slums, hard-to-reach areas and eco-hazardous zones such as hill tract and hillocks, dry and arid barind tract, salinity-prone coastal belt, haor and flood-prone chars keeping an eye over the climate change implications. We, along with our partner NGOs, have successfully developed and implemented a model approach for providing sustainable community managed WASH services and facilities for poor, extreme poor and socially excluded people in geographically and technically challenged contexts of Bangladesh. We have been enhancing our partners’ as well as of sector stakeholders’ capacity for establishing systems in program delivery, monitoring and evaluation (physical and financial), human resource and others to facilitate pro-poor, gender sensitive, cost effective, and sustainable WASH services. We facilitate community people to demand their WASH rights, capacitate and sensitise Government and other duty bearers to respond to the peoples need, and advocates for the essential role of WASH in human development.
