Perimeter of Collective Management (PGC) - Métropole

The Perimeter of Collective Management (PGC) is a portion of the territory in which the authorization to withdraw water for irrigation use* is issued for a given period and resources to a Single Organization (OU) of Collective Management.
The collective management of irrigation withdrawals, explained by Decree 2007-1381 of 24 September 2007 (Articles R211-111 to 211-117 and R214-31-1 to 5), aims to promote collective management of water resources on a coherent hydrological and/or hydrogeological perimeter. This includes entrusting the distribution of the volumes of irrigation water to a Single Body (OU), a legal person governed by public or private law, which by its designation represents the irrigators on a specific adapted perimeter.
The global authorization to draw water for irrigation, on the perimeter concerned, is issued to this OR.
If an OR is designated on several CMPs, it is not possible for it to pool direct debits between these different perimeters.
The founding regulatory text of the PGC is the departmental decree designating the OU. It specifies on which resource(s) the OU is created.
It also defines global withdrawal volumes allowed for a given resource and period.
For a given order, the periods do not overlap. They must be joined.
