Water distribution zones in the department of Orne.
Description
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 the needs.
The ERAs are defined by Article R211-71 of the Environmental Code and fixed by order of the Basin Coordinating Prefect. The list of municipalities on the perimeter of an ERA is fixed by prefectural decree.
The 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 with a capacity of 8 m³/h or more are subject to authorisation; all others are subject to reporting.
