Map Viewing Service (WMS) of the dataset: ZRE du Vaucluse (84)

A Water Distribution Area (WRA) is an area comprising basins, sub-basins, aquifer systems or fractions thereof characterised by a lack of resources, other than exceptional, in relation to needs. The ERAs are defined by Article R211-71 of the Environmental Code and are set by the Basin Coordinating Prefect. The decree issued by the department prefects concerned translates the ZRE into a list of municipalities. This decree is the founding regulatory text of the ERA. In an ERA, the thresholds for authorisation and reporting of samples from surface water and groundwater are lowered. These provisions are intended to enable better control of the demand for water, in order to ensure the best preservation of aquatic ecosystems and the reconciliation of economic uses of water. In an ERA, water withdrawals greater than 8 m³/h are subject to authorisation (except those which are subject to a convention on the flow rate assigned under Art/R211-73 and those less than 1 000 m³/year deemed to be domestic) and all the others are subject to reporting.
