Safe and adequate water supply and sanitation in schools are pre-requisites for the right to basic education for school children (Mooijman 2012). The provision of adequate water, sanitation and hygiene (WASH) facilities in schools has been linked to the achievement of the Millennium Development Goals (MDGs) on universal primary education, gender equality and child mortality, and more recently to the achievement of the Sustainable Development Goals, and in particular Goal 6 on clean water and sanitation by 2030.
