1969
The Bauma wastewater treatment plant (WWTP) was built in 1969 in Saland for a population of 6,000 and was renovated and expanded for the first time in the mid-1990s.
2035
The groundwater flow under the upper Töss supplies the Tösstal and Winterthur with first-class drinking water. In order to protect this from contamination in the long term, the Tösstal municipalities of Fischenthal, Bauma, Wila, Turbenthal, Zell, Weisslingen, together with the city of Winterthur and the AWEL have agreed to shut down the Bauma and Weisslingen wastewater treatment plants by 2035. The wastewater from the Tösstal valley would then be directed to the ARA Hard in Winterthur. It is planned to establish a joint institution under the name "Regional Wastewater Disposal Tösstal". In the referendum on 19 May, the foundation of the GA was clearly approved. The new institution is to be founded in 2020 and create the infrastructure for the upper Töss to be free of wastewater.
