Perimeters of protection of the hydrothermal deposit

zone 1 corresponds to the extension of the hydromineral deposit with a high risk of major impact on the characteristics of the water table;

zone 2 corresponds to the predominantly upstream territory representing an intermediate risk on the hydromineral deposit;

zone 3 corresponds to an area of influence on the wider water table, over which risks exist depending on the scale and characteristics of the proposed work.
