Water

90% of the water distributed by Martinique's drinking water network comes from Rainwater intakes in five catchment areas. Thus, although there is no shortage of water, the situation becomes very critical in the Lenten period, with abstractions leading to the drying up of several rivers.

Water resources are abundant but unevenly distributed: Four municipalities (Saint-Joseph, Gros-Morne, le Lorrain and Fort-de-France) provide 85% of Martinique's drinking water.

There is no water catchment in the south of the island. The water consumed in the South comes exclusively from abstractions from the North and the center (mainly from the Blanche River which flows into the Lézarde, the Capot, and the Dumauzé). Thus, 60% of the total is extracted from a single river (the Lézarde and its tributary, the Blanche river). This concentration of abstractions can constitute a risk in a crisis situation, such as a drought for example.
