The county sewer mainline is a sewage tunnel running underneath the Capital Wasteland.

Layout[edit | edit source]

The tunnel can be accessed from either inside the sewer waystation or a sewage grate along the Potomac River, just north of a raider camp under the west point of the Francis Scott Key Bridge. It goes under Grayditch and Arlington Cemetery, but has no access points there. It is the home of Gallo, as well a number of feral ghouls and radroaches, and contains a large number of workbench items.

Gallo's home[edit | edit source]

Nearby the waystation access point (the right path after entering via the waystation) is a hostile ghoul named Gallo, whose room is located past several traps in the northwest region of the sewers. In Gallo's footlocker his storage key can be found which is used to access a storage closet nearby. Gallo's room also contains a small Nuka-Cola collection, a safe, as well as a pen of radroaches. There is a bed here too, and quite a few shelves.

If Gallo is killed, it can be used as player housing (though the Lone Wanderer cannot technically own it). It also contains 40 railway spikes and a Stealth Boy hidden in a box on a bottom shelf, along with some chems and ammunition.

Gallo's storage closet contains the following workbench items:

Sewer management main room[edit | edit source]

The sewer management main room is located in the central region of the mainline. It is occupied by a number of radroaches and feral ghouls. The storage closet can be accessed from a terminal behind a locked gate nearby. A number of chems, ammunition, and workbench items can be found inside.

Sewage tunnels[edit | edit source]

The sewage tunnels that compose most of the mainline are littered with the remains of dead mercenaries and wastelanders. These are often marked by the presence of feral ghouls nearby. Boxes of ammunition can be found near (or under) many of the remains.

Behind the scenes[edit | edit source]

In the tunnel between the sewer management main room and Gallo's home, there's a strange skull with glowing eyes stuck on a metal rod, with two smaller rods crossed just under it. This is a subtle reference to the Khans from Fallout and Fallout 2.
