The existing drainage line (collecting line) at the hamlet of Wishof is to be connected to the rainwater sewer that is to be newly built. Stadtwerk Winterthur intends to replace the gas and water lines as well as the electricity line in the Wespimühle/Bridge over Töss section. After the excavation work, the Wieshofstrasse will be renewed in the Schlosstalstrasse section to the hamlet of Wishof and a new pavement will be added. The draft preliminary project from the civil engineering department of the city of Winterthur serves as the basis for the road construction project.
