Access to water and sanitation facilities is a right for all people, including those with temporary or permanent impairments such as injuries and disabilities, and also other vulnerable groups including pregnant women, elderly people, overweight people and those with chronic disease to fulfil their basic needs. They represent usually at least 15% of a population and this is often higher in emergency settings (WHO and World Bank, 2011). Access to facilities should be promoted through physical accessibility as well as a positive attitude towards encouraging persons with particular vulnerabilities to use these accessible facilities.
