Abstract
There are many people in the world who cannot access to the safe drinking water and appropriate sanitation. To halve these populations is one of the common goals for the world. In Bauniabad, one of the urban poor settlements in Dhaka, Bangladesh, many aid agencies have been working to improve sanitation conditions. In recent years, biogas plants have been installed as sanitation and people have been sharing a part of installation cost. The purpose of this study is to clarify the background of how poor people came to prefer and to use the biogas plant system as sanitation and the effectiveness of the biogas plant through questionnaire to the local people, interview to the stakeholders, and water quality analysis. It was revealed that though still people showed the difficulties to share all the cost of installation of the biogas plant, with the combination of the education on public health, there is a possibility to accept the cost share when people could understand the benefit of the option to their health and life.
