Water supply and sanitation in Zimbabwe is defined by many small scale successful programs but also by a general lack of improved water and sanitation systems for the majority of Zimbabwe. According to the World Health Organization in 2012, 80% of Zimbabweans had access to improved, i.e. clean, drinking-water sources, and only 40% of Zimbabweans had access to improved sanitation facilities. Access to improved water supply and sanitation is distinctly less in rural areas.
