Underground development of the Tamina Gorge

Within the framework of the spatial tourism development concept (Räumliches Tourismusentwicklungskonzept RTEK) Bad Ragaz and Pfäfers, the Tamina Gorge is to be upgraded. In addition to a staging of the thermal spring and various measures in the old Bad Pfäfers, the concept provides for a new development of the Tamina Gorge from Valens. Special attention will be paid to a possible endangerment of the thermal spring Pfäfers, which is very important for tourism and economy.

On behalf of the Office for Economy and Labor of the Canton of St. Gallen, SCAUT prepared a feasibility study for the underground development of the Tamina Gorge. The aim was to show, among others, the following elements:
• Geological feasibility / geological risks
• Study of different alignment options
• Design of major project elements
• Cost estimation
• Risk assessment

The SCAUT members Dr. Bernasconi (geological and hydrogeological assessment) and Amberg Engineering (specialist tunnel construction planning) were called in as sub-planners to provide technical support during processing.

The results of the feasibility study were presented to representatives of the Canton of St. Gallen and the affected municipalities in November 2020. The partners will now evaluate the results and determine the next steps.
