Bio-Digester Construction Manual (2020)

The bio-digester toilet technology is one of the fastest growing toilet options in urban Ghana. The use of bio-digesters has been given a boost by the World Bank-funded GAMA Sanitation and Water Project (2014-2020), which seeks to provide improved sanitation to low-income urban areas. Currently, bio-digesters are the predominant toilet technologies in the low-income communities within GAMA, with about 98 % of all constructed household toilets under the project being bio-digesters. The number of variants of the bio-digester has increased over the years, with different service providers providing different designs and configurations of the technology. This has necessitated the need for standardization through a construction manual.
