Kibera still is one of the biggest informal settlement in Kenya and in Africa, with a higher number of NGO presence than any other part of Kenya. Till 2012-13 Kibera lacked proper drainage system and people relied on the pit latrines, however with the new devolution Ministry major parts of Kibera now has proper drainage system. A latrine is shared by up to 20 households. When full the waist is removed by mainly young people for a fee and at times drained to the river. Most of the community owned schools within Kibera suffers the most. Due to lack of enough space within the schools, they are forced to dig the pit latrines next to the classrooms making the children vulnerable to diseases.
