Rainwater as a source of drinking water: A resource recovery case study from Vietnam

Abstract

A successful Rainwater For Drinking (RFD) system was implemented at Ton Due Thang University, Vietnam. In technical design, uncertainties in water quality were resolved with multiple barriers and IT-assisted monitoring to maintain safe drinking water. From a social perspective, the university was the most effective platform for RFD promotion and education. Further, contributions from the beneficiary resolved the lack of a sense of ownership and economic problems by using local labor and materials. The results demonstrated the possibility of using rainwater as drinking water, allowing it to be promoted for Sustainable Development Goal 6: Clean Water and Sanitation (SDG6) achievement.
