One-off weakening of the water table or excessive withdrawals? Around Volvic (Puy-de-Dôme), water is scarce and discontent rises against Danone, owner of the famous mineral water, accused of “emptying the bathtub” at the expense of the environment.
“We had water up to our knees and the stream made two mill wheels turn,” recounts nostalgia, Pierre Grodecoeur, 69, facing the stream that runs alongside his birthplace.
The mill is long gone and the stream is now often dry.
Not far away, the Saint-Genest-l’Enfant fish farm, listed as a historic monument, also lacks water. It is however there that the water of Volvic gushes out after its course in the volcanic rocks.
The place is bucolic, with its XNUMXth century basins made of Volvic stone, hollowed out in the shade of alders and plane trees.
But since 2017, several months a year, the sources are drying up. The walls of the pools sag and the duckweed proliferate, transforming the liquid surfaces into green mirrors. The exploitation had to cease.
“In 1927, the flow was measured at 470 liters per second against 50 liters per second today” explains Robert Durand, a geologist interviewed by AFP.
“Danone destroys a historical monument to send pieces of plastic to the other side of the world”, plague the owner Edouard de Féligonde who is leading the fight in court, with his lawyer Corinne Lepage.
A report, a copy of which was sent to AFP, concludes “an underground relationship between the boreholes exploited for water from Volvic and the Gargouilloux source”. But Danone, which funded this research, did not wish to publish it.
“Beginning of desertification”
Downstream, the lack of water “acts on the biodiversity of wetlands”, deplores Christian Amblard, honorary researcher at the CNRS in Clermont-Ferrand.
“We can speak of a beginning of desertification” going hand in hand with “the decline of vegetation and associated fauna: black alder and alder siskin, ash and European oriole”, explains the scientist .
“Only the hand of man and Volvic are responsible,” he asserts.
Like him, associations and residents are questioning the responsibility of Danone and its Société des eaux de Volvic (SEV), whose bottling plant is located a few hundred meters as the crow flies.
On March 21, several hundred people demonstrated for World Water Day, at the call of the Eau Bien commun 63 collective.
“Today, the flows no longer allow the crops to be irrigated. In recent years, there has been no market gardening or horticultural activity in this area”, notes Laurent Campos-Hugueney, member of the collective and spokesperson of the Peasant Confederation.
The SEV boreholes reach 100 meters deep: “it’s like emptying the bathtub from the bottom”, explains François-Dominique de Larouzière, geologist and member of the Association for the protection of entrances to volcanoes of Auvergne (Preva).
“Danone shoots himself in the foot, but when there is no more water at the tap, it will hurt,” he predicts.
The multinational collected 2,33 million cubic meters in 2020, or nearly a quarter of water uses in this territory, half being reserved for drinking water and the rest in the natural environment.
Danone claims to have limited its withdrawals, while carrying out various actions to protect the impluvium, the area that collects rainwater.
“We saved 380 million liters between 2017 and 2020 for stable sales levels,” Jérôme Gros, director of the Volvic factories which employ 900 people, told AFP.
