More than 5 million rural Cambodians are without access to safe and clean drinking water and over 9 million are without sanitation. The average annual income per capita is $950 USD, often significantly lower in rural areas. Most of Cambodia’s available ground water, surface water and open wells are contaminated with human waste, animal waste, industrial runoff and contaminants such as E. coli bacteria, arsenic and hepatitis A.

Our BioSand filters are constructed from gravel, sand and a biological layer to remove over 99% of harmful disease-causing bacteria from dirty water poured through it. They’re an effective, easily-maintained, low-cost solution, that don’t depend on power. Families, schools and community members donate time to help build their BioSand filter and contribute a small amount of money towards their project, which creates a sense of ownership, knowledge and investment. Our holistic approach means we also excavate large ponds for rainwater catchment, build handwashing stations, dig wells, build latrines and provide ongoing training, monitoring and evaluation.
