Updated on 06/09/2018
Définition
Sens commun
Amount of money due for water withdrawals, regardless of the user (municipality, industry, farmer) according to specific thresholds.

Charges/fees for water storage during low-water periods

Updated on 06/09/2018
Définition
Sens technique
Amount of money paid by people who store all or part of the volume flowing into a river during low water periods (provided that the capacity of the facility is greater than one million cubic meters). The amount of this fee depends on a rate and a basis, the latter being the volume of water stored during the low water period. The period and the rate are defined by the river basin authorities, according to the hydrological regime of the river.
