The entrance to this sewer system is close to the Dam Facility where the protagonist exited the Ark 437a, and the Wasted Garage main entrance. Once the player can return to the area, they may start looking for a red tent underneath the overpass, near the ramp leading up from the area. There, the player will find a prospector named Steiger standing near the hatch. Steiger warns them that the sewers are a dangerous place crawling with mutants, but he also mentions that the mutants have stored their loot in the sewers, suggesting that the player might find several valuables.
