In drought-stricken France, tankers supply drinking water

In the Alsace region of eastern France, large tanker trucks have become a common sight, delivering essential drinking water to towns like Sainte-Marie-aux-Mines. This unusual measure is a direct response to weeks of intense heat and a severe drought that has depleted local water sources.

Sainte-Marie-aux-Mines, a town of 5,000 residents nestled in the Vosges Mountains, typically relies on about 20 mountain springs. However, the prolonged drought has drastically reduced the flow from these springs, forcing authorities to seek alternative solutions. Water is being trucked in from the nearby town of Liepvre, which still has sufficient reserves, though a permanent connection between the two water systems does not exist.

Nationwide, the drought's impact is significant. The French government reports that over 40,000 people have experienced water cutoffs or supply disruptions this month, with an additional 550,000 at high risk of losing stable access. While water restrictions are widespread, the use of tanker trucks is reserved for specific areas where municipalities cannot easily switch to alternative resources.

This reliance on tanker trucks is not unprecedented in France. During the exceptionally dry summer of 2022, hundreds of municipalities faced similar water shortages, resorting to bottled water or emergency deliveries. The situation also points to underlying issues with water infrastructure, as seen in Coucouron, a village where repairs to leaks significantly reduced water consumption, demonstrating the impact of aging pipe networks.

Beyond water supply, the extreme heat and drought are taking a considerable toll on the French economy. The environmental transition minister has estimated that the direct and indirect costs associated with this year's heat waves could reach €10 billion. The situation underscores the growing challenges France faces in managing its water resources amid increasingly frequent and severe droughts.
