Solid waste management, phases 1 and 2, Benin

In 1992, Dessau completed the study of a master plan for the deployment of a solid and liquid waste treatment and collection systems in the main cities of Benin.  The client, extremely pleased with the results, mandated Dessau for the the integrated planning study, and to act in the capacity of implementation management agency, for the study and the implementation of solid waste management program of Cotonou, Benin's capital.  The main components of this second phase involved the improvement of the access road and the Sanitary Landfill management; the Sanitary Landfill manager selection, support to the city of Cotonou for the implementation of structures and waste management tools; support to the implementation of environmental follow-up program; support in the communications plan development (1992-2005).

InfEAU gest, Burkina Faso

In 1998, Dessau was mandated by the IEPF to improve traditional technological transfer channels and electronic tools to favor communications between the various interveners of a same field of expertise.  During phase 1, the project's objective was, in the short term, to develope a tool (water management software, HTML) to assist Burkina Faso's water managers in their decision taking process and in a longer term, to implement a data network system accessible to the water managers.  During phase 2, the project's objective was to develop a more generic version of the tool, so as to implement it and allow its utilization in several countries of the French speaking West African region, such as Niger, Mali, Togo and Benin and to implement it in other countries.

Solid waste management Master Plan, Burkina Faso

In 1998, Dessau was mandated by the World Bank to develop the solid waste management Master Plan for Burkina Faso's two main cities, namely, Ouagadougou and Bobo-Dioulasso.  Among the Master Plan main components are included: the residential solid waste collection,  the organization of public consultation assemblies and the preparation of a multimedia kit to inform the population; the conception of tight burial cells for industrial and biomedical wastes and the preparation of a manual for municipalities.

Technical studies related to the strategic planning of Tombouctou's water sanitation program, Mali

Dessau was mandated in 2000 to support the localitiy of Tombouctou in the implementation of the strategic plan for the city's sanitation program.  The main elements of the plan were distributed into three distinct units:  rain waters, domestic wastewaters and municipal solid waste.  The project involved preliminary planning (Assessment center method for the entire territory except for the Kabara region), detailed project plans (covering the sector of the "medina" marked by the beltway) and the strategy itself.

Environmental impact studies and construction of three mini hydroelectric power stations, Dominican Republic

The project includes the engineering, provision and construction of three small hydroelectric power plants by taking advantage of the hydroelectric potential of the existing dams and irrigation channels, as well as the electrical distribution networks. The main objective is consequently, the improvement of the quality of life for the region, taking the energy to rural populations that do not rely on the electrical service, or who receive it on a precarious basis.   The works will have a minimum ecological impact,  the natural habitats are not to be modified, since they take advantage of the existing channels.   Local companies were hired for the accomplishment of some works, for the transfer of technology and engineering data for the future operation and maintenance of the equipment.  The run-of-river power plants range in power from 1 to 2 MW and are located inland near the cities of San Juan, Las Barías and Canal Boba.  The turbines installed were of Francis and Kaplan type.   The project registers within the framework of a program of the national authorities for the future construction of small hydroelectric power stations throughout the country.  Dessau provided original solutions in response to specific client requirements, including the supply of engineering services, procurement, construction management and the financing structuring for the entire project (2001-2002 environmental studies; construction: ongoing since 2004).

Land improvement fossil valleys, Sénégal

In 1997, Dessau was mandated by the "Organisation pour la Mise en Valeur du Fleuve Sénégal (OMVS)", in collaboration with SNC-Lavalin International (Canadian company) and Hydroconsult International (Senegalan company), for the project studies and planning related to the re-invigoration of the Sine and Ferlo valleys.  The program's objective is to improve quality of life for approximately 25% of the national territory, identifying several hydraulic diagrams to recover a portion of the Sénégal River annual excess and transfer it through a pumping, channeling and stockage system into the Ferlo River's reservoir, so as to create a continuous water accretion source and improve the overall territory's condition.  The program also covers the landscaping and development of affected areas.
