The Mayenne basin has been modeled previously by the NOPOLU system (developed by Béture-Cerec) and has been studied intensively as part of the French 'Comité de Pilotage' activities on detergents. The project involved the collaboration with the AISD/AFISE (French Soap & Detergents Association), the Ministry of the Environment, and the Basin Agency 'Loire-Bretagne'. Sponsor for the Mayenne project was ERASM (AISE/CESIO). The engineering bureau Béture-Cerec has been selected as contractor. Project leader was Dr. Guillaume Le Gall. The Mayenne project started January 2001 and was delivered end 2002. Top of Page
