Source of Water in Lyon, France

Lyon’s tap water comes mainly from groundwater drawn at the Crépieux-Charmy well field, northeast of the city in Vaulx-en-Velin. This groundwater is naturally replenished and filtered through the alluvial sediments of the Rhône River.

Additional wells in the Lyon metropolitan area supplement the supply. The water is treated, monitored, and distributed by Eau du Grand Lyon through the public network.

Lyon Drinking Fountains

Yes, public drinking fountains in Lyon that are marked as drinking water are generally safe to use and supplied under France’s strict public water quality standards. The water is routinely monitored for microbiological and chemical safety.

Use only fountains clearly labeled as potable, and avoid decorative fountains or outlets marked “non potable.” Let the water run briefly if the fountain has not been used recently, and do not drink if the outlet appears damaged or unclean.
