Rainwater harvesting systems for a high quality, supplementary water supply in Nepal

In 2010 it was estimated by the World Health Organisation (WHO) and the United Nations International Children’s Emergency Fund (UNICEF) (2012) that 89% of Nepal’s population had access to an improved water supply source, however, the Government of Nepal (2011) estimated that approximately half of those water supply systems were not functioning properly. Nepal Water for Health (NEWAH) is a Nepali non-government organisation that has implemented several rainwater harvesting systems (RWHS) in the rural hilly regions of Nepal.
