Two new plants in the Valais

Authorities from Ardon, Conthey and Vétroz united for a two line treatment project with a maximum capacity of 500 m³/h (11'000 m³/day). For Conthey, another plant of this size had already been built in 2003.

 The other plant of 120 m³/h has been conceived for the well-known winter sports resort of Champéry. It includes an intricate regulation for the management of each spring's contribution as a function of its quality and the overall water demand.
