The invention relates to a method for determining a maximum allowable volume of water that can be removed over time from an underground water source, the volume of water being removed at a removal point and the hydrogeological state of the underground water source being qualified by piezometric measurements on a reference piezometer, the method being characterized in that it includes, in particular, a continuous measurement by a first piezometric level sensor on the removal point, the sensor having a first log of available data over a predetermined period that has passed; and another continuous measurement by a second piezometric level sensor on the reference piezometer, the second sensor having a second log of available data over the predetermined period that has passed; the method also comprising subsequent steps implemented by a calculation machine.

Method for determining a maximum allowable volume of water that can be removed over time from an underground water source

A system for quantitative water management comprises: at least two interconnected water production entities (U), at least one water resource (S) linked to one at least of the production entities (U), at least one demander element (D) requesting water produced defined by a pre-established temporal curve of water demand produced as a function of time, each link between production entities (U), water resources (S) and demander elements (D) being ensured by a transfer work (C) having a predetermined maximum flowrate and being able to be interconnected, each production entity (U) and each water resource (S) furthermore being associated with a weighting function P, and a calculator adapted to minimize the global weighting function Pg of the system while guaranteeing compliance with the pre-established temporal curve of water demand produced of each demander element (D) under constraint of compliance with the maximum flowrates of the various elements of the system.
