The village of Maziwa Ngombe has a population of about 6,000 in about 1,500 houses, at least 1,000 of which have no running water or sanitation. Streets often flood during the rainy season, and cholera outbreaks are common. 2015 was especially bad, and for a time the village school had to be used as a hospital.
In cooperation with village leaders the Pemba Foundation designed 2 public toilet buildings, hired local workers and managed construction. The Foundation also upgraded the water supply and installed a storage tank for a public toilet building built some years ago in Mjini Kiuyu village.
