Water, Sanitation, and Hygiene (WASH)
At Sian Biogas, we are committed to improving public health and environmental sustainability through innovative solutions. Our WASH initiatives target institutions, markets, and underserved communities to ensure access to clean water, improved sanitation, and hygienic practices.

Lack of adequate sanitation and safe water access remains a significant challenge in many communities. Poor sanitation not only affects health but also the environment, leading to waterborne diseases, contamination of natural resources, and a decline in community well-being.

Our prefabricated and fixed dome biodigesters are designed to manage human waste effectively while producing biogas for energy and clean water from slurry, offering a comprehensive WASH solution.
