Water resource

Sens technique

Source potentielle d'approvisionnement en eau permettant de satisfaire des besoins en eau liés à certaines activités humaines, par l’intermédiaire d’actions de prélèvements réalisés à partir d’ouvrages de prélèvement. Certaines ressources en eau peuvent être, dans une certaine mesure, considérées comme étant de nature artificielle, dès lors que leur répartition territoriale émane d’une intervention humaine (exemple : plan d’eau artificiel, bras d’eau artificiel,…). Le suivi des pressions exercées par les prélèvements d’eau est réalisé à la fois au niveau des ressources naturelles, mais aussi artificielles.

En tenant compte des concepts ayant été définis dans le cadre de la mise en place du Système d’Information sur l’Eau (SIE), une ressource en eau peut correspondre à l’un des concepts suivants :

un cours d’eau (cours d’eau naturel ou aménagé, un bras naturel ou aménagé, un canal,…), ·
un plan d’eau y compris citerne, réservoir ou bassin de stockage, ...
une entité hydrogéologique,
une mer / un océan

Charges/fees for water storage during low-water periods

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.

Charges/fees for water abstraction/withdrawal

Sens commun

Amount of money due for water withdrawals, regardless of the user (municipality, industry, farmer) according to specific thresholds. This fee usually has two components: one based on the amount of water withdrawn, the other on the amount of water consumed (i.e. taken and not returned to the natural environment).

Use restriction

Sens réglementaire

Exceeded limits lead to restrictions of use and water withdrawal, to cope with a shortage of water resources during low water periods. Restriction measures are defined locally by the prefects. Generally, measures to limit withdrawals are progressive (depending on the thresholds defined for vigilance, alert, quick reaction alert or crisis) and adapted to different uses (domestic, agricultural, industrial).
