Schéma directeur d'aménagement et de gestion des eaux
In France, the schéma directeur d'aménagement et de gestion des eaux (SDAGE) aims to put into effect the principles of the law of 3 January 1992 on the level of the major hydrographic basins. In translation, its name is outline for the organization of the development and management of water resources. Rationale. Water is a part of the nation's common heritage. Its protection, exploitation and setting into a usable state while respecting natural balances, are of general interest. The use of water belongs to all, within the framework of laws and  regulations as well as of rights already established. The law. The law of 3 January 1991 is like a United Kingdom Act of Parliament. The main subjects addressed by the SDAGE are written into the law: The SDAGE scheme was drawn up together by the national, regional and département governments and is managed by the "agence de l'eau" (water agency). How it works. The SDAGE serves as a general framework for the development and management of the water of each hydrographic unit, system or aquifer). These are the schémas d'aménagement et de gestion des eaux (SAGE), that is water resource  development and management outlines. The aquifer and the hydro-electric and recreational uses of water in the Ain valley compose a clear example of a site where a coordinated approach could be productive. However, the "schéma" is flexible enough to include specific needs as for example, that of Artois-Picardy, which is concerned specifically with the former mining basin of the Nord and Pas-de-Calais départements and the consequences of past and current exploitation of the région's coal.
