A pipe failed during the night from Saturday to Sunday on Quai Gustave-Ador. It caused possible pollution on a large part of the left bank, from Vandoeuvres to Hermance.
Tap water is unfit for consumption for 27,000 inhabitants of nine Geneva municipalities on the left bank — Thônex, Choulex, Corsier, Vandoeuvres, Collonge-Bellerive, Hermance, Hermance, Hermance, Anières, Anières, Puplinge and Cologny — due to the rupture of a water pipe.
