From the snow on the high peaks to the tap, there's just one step: catchment of the water sources. Located over 2,150 metres above sea level at the entrance to the valley of La Moulette, the upper catchment of La Moulette supplies the municipality of Le Monêtier-les-Bains with a proportion of its drinking water. With 164 thousand cubic metres of underground water abstracted every year, this is an important water source for the village. The water is naturally drinkable and meets the quality requirements in force for every parameter measured by health controls.
