Water crisis is the most crucial problem in the southwest coastal region of Bangladesh. Though there are lots of surface water but neither they are drinkable nor useable for household purposes because of salinity, turbidity and other bacterial contamination. Bio-sand filter is a viable water treatment technology in household level. The filter was designed by Dr. David Manz in the 1990s and has been widely tested since that time. It is made out of locally available materials. LEDARS introduced this technology in the coas
tal area since 2007 with support of CAWST and MIT. Since 2015, LEDARS is implementing “Biosand Filter Project in Southwest coastal Bangladesh” project with support of OHorizons Foundation, USA. Major activities of this project are to identify vulnerable families who have scarcity of safe drinking water, install Biosand filter to the families, and regular monitoring of the filters if they are active or not. Till now, LEDARS installed 5250 BSFs in the households. LEDARS provided orientation about water resource management, Biosand filter management, etc.
