Inside the Wall part of the Network
The City Technical Network is a presumably complex system of Walled City 99. This is the infrastructure system that allows to purify water, save it and transport it to the residents of the city.
City Technical Network includes Sewers and Antvillage, Inside the Wall, wastewater river of Dead End and probably other places that were not mentioned in the game. The Network does not include a trash recycling system or the City's computer network (in which B-12 was stuck).
Background[]
The sewer system. Yes, I remember now. Clean water was scarce. The city was supplied by huge machinery that dug deep into the earth. Just like everything else, it was rationed out to sustain people during times of drought. The Scientist showed me the blueprint of the water tanks. They are huge and could contain a whole building in them.
B-12, Sewers memory
Clean water was scarce on an uninhabited surface and in the Walled City 99. Water for the City was extracted from underground, and then, using the City Technical Network, it was delivered to Humans.
After the death of Humans, the work of the City Technical Network was supported by Companions, because in the game you can see the machinery with droid letters there. However, the part of the Network located Inside the Wall was abandoned due to the inability to go to The Outside. At the moment of the actions taking place in the game, the Technical Network is partially working: the water is not cleaned properly, and the Sewers are occupied by Zurks, Fleshy Walls and Flesh Eyeballs.
Technics[]

Second Companion in Debug mode
Most of the City Technical System is controlled by computer equipment. There we can see a technique for controlling sewer doors, ventilation, lighting, alarm systems, as well as several broken Cameras.
In two places in the Sewers, you can stumble upon the bodies of Companions connected to walls. One of them has no head, it is not connected to any equipment and it is in a bright room after the gate that Momo opened for the Cat. There is a "Human personnel only" sign in front of the entrance to that room. The second Companion is located deep in the Sewers, and their body is connected to an electrical device. When this Companion sees the cat, they will turn their head in his direction, and then lower it again. The game files say they are charging themselves.
The main equipment controlling the operation of the Network are Sewers Control Panels. As the name implies, they are installed in the Sewers, the largest part of the Network.
