In India, 15 lakh children are estimated to die of diarrhoea and 7.3 crores working days are lost due to waterborne diseases resulting in an economic burden of ₹3900 crores a year [1]. Explorations in the villages, where Gram Vikas works, show that water quality issues caused by bacterial contamination and nitrates, and turbidity is a primary concern.

At Gram Vikas, we define safe drinking water as free of bacteria (causing Diarrhoea, Cholera, Dysentery, Typhoid), without nitrate (causing ‘blue baby disease’) and having an acceptable taste.

Gram Vikas is working towards building a programmatic framework for community-level drinking water quality management. We build village level capabilities for quality testing and preliminary diagnosis, as well as taking up necessary repairs/ redressal measures.

The community will be trained to test the quality of water using test kits and equipment, and district labs will test for contaminants that cannot be detected locally such as arsenic, iron, chlorine, TDS, pH and water hardness for calcium and magnesium.

A technology platform will be developed to serve as a capacity-building tool for the communities, and an information tool for aggregating drinking water quality status. The platform will enable the village-level volunteer and/or the members of the Village Water and Sanitation Committees to manage drinking water quality at the village level.

Those wells found to be defective will be repaired to prevent pollutants from entering the water. Village members will be trained to undertake the necessary repairs building sustainability of the initiative and building skills among the youth.

A full support eco-system for handling quality issues that require more intensive interventions will be created at different levels. This self-funded initiative is a collaboration between Gram Vikas and the village communities.
