WatSan Action works with disadvantaged Indonesian communities to improve water & sanitation conditions through educational activities and participatory projects. To achieve this, we have structured our work into the following four programs: -Developing awareness of practical means of improving water, sanitation, and waste conditions. -Facilitating access to clean water and introducing household drinking water treatments. -Promoting waste as a resource and proper solid waste management practices. -Improving and developing latrines, in addition to drainage and infiltration methods.
