Montafon Sewage Board

The wastewater treatment plant (WTP) of Montafon valley located in Vandans/Vens started operations in 1985. The WTP has been regularly updated with state-of-the-art technology and is considered a nationwide showcase project.

The Montafon Sewage Board comprises the eight Montafon municipalities of Bartholomäberg, Gaschurn, Silbertal, Schruns, St. Anton im Montafon, St. Gallenkirch, Tschagguns and Vandans. 

Thanks to its continuous development, the wastewater treatment plant of the Montafon Sewage Board has been regarded as an ecological and economical showcase project since its inauguration. For one, this is owed to the fact that two combined heat and power stations are used to process the accumulating sewage gas and produce 100% green energy and heat. In addition, the waste heat is used for drying at the neighbouring wood chipping plant of the Stand Montafon Forest Fund.

Every day, the wastewater from roughly 8,000 households and 750 commercial enterprises is purified at the wastewater treatment plant located in the municipal territory of Vandans, corresponding to more than two million cubic metres of wastewater per year. The municipalities continuously invest in the Montafon WTP to ensure that it always meets the current needs and legal requirements.
