Pit latrines and participation: the MAPET Project in Dar es Salaam

The authors report on a neighbourhood-based sanitation service set up in Dar es Salaam using appropriate technology for emptying pit latrines; the Manual Pit Latrine Emptying Technology (MAPET) project. The participatory development process and use of technology fitting the localised scale of the project contributed to its success, while notable lessons learned include the need for the cooperation of a local agency (whether an NGO or local government) in purchasing and replacing equipment.
