The Aden Municipal Services Project is part of a larger project administered by the Government of Yemen and the Dutch Ministry for International Cooperation. The project focuses on the privatization of solid waste collection services in four cities, and the establishment of centralized storage facilities for spare parts for the collection vehicles. A proposal was formulated for an Environmental Health Education Programme in support of the AMSP, taking community participation and gender issues into account. After the end of the military regime in 1991, the city of Addis Abeba experienced such an influx of people that the public infrastructure could not keep pace with the demand for services. The regional municipal authorities, together with some NGOs, have been operating a latrine emptying service using donated suction trucks that can only empty a limited percentage of the various types of latrines.
Insufficient profitability has to date prevented the entry of any private companies into the market.
All three technologies were operational in Dar es Salaam in 1993. The study identified a set of parameters to guide the choice of technology for pit emptying in order to evaluate the effectiveness and efficiency of each service. For Dar es Salaam, the accessibility to the latrines appeared to be the key parameter in selecting one of the three technologies. The responsible agency should therefore endorse and support the use of all technical approaches, in order to enjoy the advantages of each of the technologies in varying circumstances. In close cooperation with the Dar es Salaam Sewerage and Sanitation Department, pilot equipment and a pilot institutional framework were developed to perform a pilot collection trial using a public-private pit latrine emptying service for the urban fringe areas of Dar es Salaam.
