Hygienic sanitation facilities are crucial for public health. Inadequate sanitation is a major cause of disease worldwide and improving sanitation is known to have a significant beneficial impact on health, both in households and across communities. Some 842,000 people in low- and middle-income countries die each year because of inadequate water, sanitation, and hygiene. Inadequate sanitation is estimated to cause 280,000 diarrhoeal deaths annually and is a major factor in several neglected tropical diseases, including intestinal worms, schistosomiasis, and trachoma.
In East Africa, many schools in rural areas lack enough hygiene and sanitation facilities, and most schools are dependent on wood and charcoal as fuel for cooking, often burned in open fires or poorly functioning stoves and causing health problems for the people involved. The aim of this project was to improve the living conditions of school children in Tanzania by providing safe and financially viable sanitation systems combined with biogas and fertilizer production to schools.
