Affordable Wells in Bangladesh

Welltracker helps people in rural Bangladesh avoid arsenic poisoning occurring naturally in about 50% of private tube wells. Despite warnings from the government, many villagers cannot afford to dig tube wells deeper than 40ft. They continue to install shallow tube wells at a fast pace.

Welltracker makes safe tube wells more affordable. Instead of the typical 800ft depth of a deep tube well, we use mathematics and statistics to find shallower safe depths. We encourage communities to invest in deep tube wells together. Our intention is to help set up an independent organization that provides loans and secures well investment with a money-back arsenic-free guarantee.

In addition to providing more affordable safe wells, Welltracker will also provide quality assurance and training to well drillers.

Welltracker was funded by the Earth Institute at Columbia University. To find more information, please contact us!
