“Hydrologic is a social enterprise that manufactures, distributes and sells ceramic water filters across Cambodia. Its roots go back to 2001 as a safe water program initiated by international NGO, iDE and to date Hydrologic distributed more than 500,000 water filters, under brand Tunsai, across Cambodia. Since 2010, Hydrologic is registered as a pro-profit business, which creates value for its customers across the country by providing long lasting product that significantly contributes to public health, environmental benefits and stimulation of rural economic activity.

About 72% of rural households treat their drinking water by boiling it. This can be effective but, in practice, boiling is usually not done properly or consistently. Boiling also comes at an environmental cost. The majority of rural households use wood or charcoal as fuel, resulting in greenhouse gas emissions and increased stress on forest resources in a country that already has one of the highest rates of deforestation in the world. Hydrologic saves about 130,000 tons of CO2 every year by shifting customers away from using wood or charcoal and opting for another water treatment method.”
