We want to contribute to healthy lifestyle of the communities that we worked with. Many of the rural communities are still lacking in sanitary facility. We promote to visiting groups to build toilets for deserving families. In Sumatra we have built numerous toilets for use by households in villages. Due to lack of facility, many still use river as toilet. River is an important drinking source for people living downstream. But promoting use of toilet, we will ensure a safe and healthy drinking water for many. At S$400 a family can have its own toilet facility. It is safe and hygienic and will ensure that the children and elderly could use it with much confident.
