Rainwater for drinking in Vietnam: barriers and strategies

For many decades in Vietnam, rainwater harvesting has been widely used as a nature-based solution in rural areas, aiming at good-quality drinking water with low cost and little energy. Recently, rainwater for drinking has attracted much attention from the Vietnam government. Furthermore, despite its efforts, the outcomes are not as expected due to local barriers. This paper reviewed rainwater for drinking demonstration projects in some specific areas of Vietnam, with identification of the technical, economic, and social barriers, further suggesting possible overcome strategies. A lesson learnt from this study would be the principle of promoting rainwater for drinking in developing countries, looking forward to sustainability. doi: 10.2166/aqua.2019.054 s://iwaponline.com/aqua/article-pdf/doi/10.2166/aqua.2019.054/610439/jws2019054.pdf Bui Thi Thuy Anh Dung Dao Mooyong Han Department of Civil & Environment Engineering #35-518, Seoul National University, 1 Gwanak-ro, Gwanak-gu, Seoul, 08826, Korea Duc Canh Nguyen (corresponding author) Sustainable Management of Natural Resources and Environment Research Group, Faculty of Environment and Labour Safety, Ton Duc Thang University, 19 Nguyen Huu Tho Street, Tan Phong Ward, District 7, Ho Chi Minh City, Vietnam E-mail: nguyenduccanh@tdtu.edu.vn Viet Anh Nguyen Institute of Environmental Science and Engineering, Hanoi University of Civil and Engineering, No. 55, Giai Phong Road, Hai Ba Trung District, Hanoi, Vietnam Hyunju Park Integrated Research Institute of Construction and Environmental Eng., Seoul National University, 35-216, Seoul National University, 1 Gwanak-ro, Gwanak-gu, Seoul, 08826, Korea Pham Dang Manh Hong Luan Nguyen Thi Thanh Duyen Hong Quan Nguyen Center of Water Management and Climate Change (WACC, Vietnam National University – Ho Chi Minh City (VNU-HCM), 01 Str. 6, VNU campus, Quarter 6, Linh Trung, Thu Duc, Ho Chi Minh city, Vietnam
