Hirsacker Lake Water Plant, Horgen

As part of the new construction of the Hirsacker Lake Water Plant, the infrastructure had to be planned separately. The new lake water plant was built on the mountain side of the railway line opposite the existing plant.
The infrastructure includes the construction of the main pipeline starting from Hirsackerstrasse as well as the construction of the clean water and return pipeline (lake pipelines) including the crossing under the double-track SBB railway line from Zurich to Ziegelbrücke.
