Troyes adapts its main drinking water point to global warming. The Courgerennes catchment field is the subject of a major renovation project.
It can supply 50 to 70% of the water needs of 90,000 inhabitants of the communes of Troyes, Sainte-Savine, Saint-André-Les-Vergers and La-Rivière-de-Corps. The 2.2 million project will be financed by the Troyes Drinking Water Authority and the Seine Normandy Water Agency.
