County Sewer Mainline

 can be accessed from Sewer Waystation or Wilhelm's Wharf. It's inhabited by lots of Feral Ghouls. A ghoul named Gallo also made himself a home here. Watch for traps in vicinity of his room. His room contains two Pre-War Books, darts, ammunition boxes, and other useful items. There is a locked storage room across from Gallo's home, accessible either through an easy computer terminal or you can use Gallo's Storage Key. The room contains railway spikes and a lot of items for making schematic weaponry.

A large room contains the Sewer Management Access Computer behind a (easy) locked gate. On the table next to the terminal are two Pre-War Books and a Big Book of Science. The terminal opens up a locked door to a storage room containing a First Aid kit, ammo box, Rad Away, shotgun shells, conductors, sensor modules, a paint gun, and a Jet.
