Many wells in Bangladesh supply water that is not suitable for drinking. It contains harmful amounts of arsenic but also manganese and phosphate. Originally, people drank from the surface waters, which, however, are highly microbially contaminated. In order to provide people with clean drinking water, AGAPE 2015 installed SIDKO filters at central locations such as market places (Maulvi Bazaar, Lahiri Mohonpur Bazaar), hospitals (Ullapara), schools and train stations (Sholop), through which the arsenic is removed by adsorption.
Some of the 2015 installed SIDKO filters require urgent maintenance.
