Safe drinking water is the biggest social crisis for the people of south western coastal region of Bangladesh. Drinking water scarcity is found everywhere in the coast. People of this area are completely dependent on rainwater and pond water for their drinking purpose. Due to lack of sufficient storage, people cannot preserve much rainwater for their use. As a result, after three or four months of monsoon, the preserved rainwater finishes. Then they started collecting pond waters for their drinking. Unfortunately, they do not purify the water and drink it directly. As a result, they fall in different water borne diseases. To reduce the water crisis of the coastal villagers UEHRF has been working on this sector.
