In ''INFRA'', the Bergmann Tunnels are featured in [[Tunnel1]], [[Tunnel3]], [[Tunnel4]], and [[Hallway]].

The first and the most important tunnel in the network, providing over 90% of the fresh water to the city, that among the citizens of Stalburg is commonly known as the "Bergmann Water Tunnel", the tunnel connects the Hammer Valley river to the [[Stalburg Central Water Plant]], moving water to the main reservoir. The tunnel hosts two major facilities lenghtwise, a [[Tunnel4|hydroelectric power plant]] build and operated in the past by [[Hammer Valley Hydro]] and a [[Tunnel2|Pine Fell Water Plant]] operated by [[Stalburg Water]], whose underground section controls the water flow rate in the tunnel, another minor water flow control facility is located between the major two. Throughout the tunnel at least 4 [[Main-Six|Water Flow Monitors]] are installed that radio communicate the state of the flow to the main control board at the [[Watertreatment|Pitheath Water Treatment Plant]] office.

The freshwater tunnel has built around it adjacent maintenance tunnels that allow workers to access various parts of the tunnel, including tunnel B3/C3 and [[Hallway|tunnel B2]] that are around 9 km long each and connect the two major facilities together, the latter spawned [[Mörkö|various myths]] around it and aroused fear among workers, advising to not use it.

The tunnel is around 14,5 km long and parts of it were bored through an underground cave structures, in which during the initial construction a species of [[Stalburg Mushroom Virus#Green Mushrooms|green glowing mushrooms]] was discovered, which thanks to the water reach of the tunnel, had spread to other parts of the Stalburg. The tunnel was conceived in the first half of 20th century after the second world war, as a response to a lack of potable water in the city due to pollution, and was constructed in under a decade, being the biggest tunneling project in the city to that date.

After the bankruptcy of the Bergmann Group in mid-February of 1980, the only remaining worker maintaining the tunnel was [[Erik]], where he did work completely alone until another worker, [[Robin]], was also assigned to this tunnel. Erik remained in position until the retirement on December 17, 1997, Robin continued to maintain the tunnel until his departure in 2010s, leaving the tunnel mostly unsupervised. According to the last performed maintenance reports, the tunnel was in a very bad shape, which was speculated to be in an imminent danger of collapsing. On August 8, 2016, a routine inspection of the floodgate controls at the Pine Fell Water Plant, performed by [[Markku Siltanen]], caused this section of the tunnel to collapse, blocking the flow of the water, and starting a chain reaction of unstability in the tunnel that caused multiple more collapses throughout its whole lenght.

Second tunnel connects [[Obenseuer (district)|Obenseuer's]] open water canals with the Freshwater Tunnel No.1 and is around 4,9 km long.

Third tunnel was considered in the 1970's and later approved for construction, the boring work on the tunnel began on May 26, 1979 and the project was expected to be completed in 1983. The tunnel was meant to house multiple hydroelectric power plants, built by Hammer Valley Hydro, and would be 7,2 km long, running from Ilanka to the Freshwater Tunnel No.1, however due to bankruptcy of the Bergmann Group in mid-February of 1980, only a small portion of the tunnel was completed.
