Property description:
As part of the expansion and conversion of the infrastructure at the former Ulrichen airfield for the Goms cross-country ski trail, the individual shelters U83, U 69, and the local magazine are to be connected to the drinking water network of the municipality of Obergoms and to the transport pipeline of the Brunni Fiesch wastewater treatment plant on the north side of the Rotten. At the same time, the Ulrichen industrial zone on the north side is to be supplied with drinking water and domestic wastewater from this zone is to be connected to the Brunni Fiesch wastewater treatment plant network. Three pump shafts for domestic wastewater are being constructed. Trenches are being dug, partly in the groundwater area, to lay drinking water and wastewater pipes and cable protection pipes. The pressure pipes were laid by a pipe contractor. The pipes were secured to the Rotten bridge by a metal construction company.
