The Brittany-based urban area has just launched its first connected industrial water dispensing station. This initiative gives new value to industrial water; while not potable, this water is suitable for many other uses.

For instance, trucks used to maintain wastewater and stormwater networks—previously supplied with drinking water—are now filled with wash water from the Croix Cholin plant.

Using a smartphone app, users unlock the station and fill their vehicles with industrial water, while the volumes drawn are automatically recorded.

Since October 2025, this system has already saved 400 m³ of drinking water. A simple, inspiring local innovation that deserves a shout-out! 🤘👍👏
