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 di!erent service providers providing di!erent designs and configuration of the technology. This has necessitated the need for standardization through a construction manual.
