A case study in Ethiopia revealed that the entrances to toilets are often too narrow for wheelchairs, forcing individuals to crawl or drag themselves on the floor to reach the toilets (Wilbur, 2010). Accessibility problems also apply to children, (chronically) ill and older people as facilities may not be within easy and safe reach. Some illnesses can generate stigmatization (such as HIV/AIDS) and people affected may suffer from exclusion and be denied access to facilities. In 2015, two out of five people in rural areas had access to piped water supplies (a form of‘improved’ supply, but not necessarily a ‘safely managed’ supply), whereas four out of five people in urban areas had piped supplies.
