Tepid sewer

The tepid sewer is a section of the Washington, D.C. sewer system. Connecting Georgetown and outer D.C. via a utility door near the bank of the Potomac River.

Layout
<!-- Beginning at an utility door near the northern bank of the Potomac River, at the end of the levee on the corner. This sewer utility way leads to Georgetown West. Entering from this utility door leads down a flight of stairs, taking the right leads to a "Storage Room" with lockers down another flight of stairs, taking a left leads directly to a storage room, before the storage room on the right is another flight of stairs leading to a security corridor. At the corner of the stairway is a wall terminal that controls the ceiling turret. Continuing straight into the "Corridor Network" is a gas leak, taking a turn to the east is another hallway collapsed right after the corner. taking the left west will bring you to a control console and a collapsed hallway right behind it, this hallway leads directly in front of the ceiling turret. On the west side of this hallway right is a stairway leading to a hallway on the east side of this hallway is a gigantic generator encompassing the entire room. After this room are two stairways, one leading east, down one floor and behind the ceiling turret and small generator. The other leading north and up one floor to a large pipe control room. This room consists of large pipes, large machines and computers on the west wall. Two standing tall and one a small control console. The norther wall used to have a door leading north to the rest of the sewer area, however it is completely collapsed, with rubble protruding into the room in the entirety of the northern section. On the southwestern side of the room is another door to a stairway, leading south and down two floors, turning and ending directly behind the ceiling turret. Continuing north leads to a large empty room with few pipes and a large control console on the northern wall. the other door to the room is on the west wall, leading to a Metro tunnel.

This tunnel runs north-south, the southern end is collapsed right after the start of a turn to the west. the northern way elevates, leads to sandbag raider defenses, These defenses are complete with construction lights level floors, with rubber mats, ammo crates, and a first aid box. To the west of the raider defenses is the raider settlement, nestled in a utility way of this metro section. The utility section has a three way corridor. To the south there are two rooms to the east is "Generator" a room with a large generator on the southern wall with a gas leak on the north wall's pipes. To the west is a communication room, with a Ham Radio on a desk and a tall computer on the southern wall, on the north wall is filing cabinets and the west wall a small generator.

To the west is the "Raider Sleeping Quarters" the residence proper, on the south wall are tables and a metal shelf with a lit lantern. On the west wall are two bunk beds in between witch is a wood bookshelf. Next to the southern bunk bed is a floor safe. On the northern wall are metal shelvings, on the eastern wall is a large counter and a refrigerator, at the north east corner.

To the north the hallway ends collapsed right after the "Storage Room" utility area's restroom. This room contains a sink on the west wall, two toilets on the south wall, two lockers on the east wall, and a gernie on the west wall in front of which is a lit trashcan fire and a table with a first aid box.

This rail line continues north and elevating, ending collapsed on top of a metro car right after the utility door to the east and continued way through the sewer. The first room off the metro tunnel is large and empty, with a door at the south east corner, this hallway leads up one story to a loud room with a generator? in the middle and two large machines on the southern and northern walls. Next to the machine on the northwestern wall is a door that used to lead to the hallway connecting the southern and northern sections of the sewer to the control room, however this hallway is collapsed.

Taking the door on the east wall leads up two flights of stairs turning left and ending at a large room. This room has many pipes running in the center. On the eastern wall is a locked storage room with a wall terminal in the northeast corner. On the west wall is the door to a hallway, it makes a turn right going north, ending at a another large room. This room has a large loud generator gated off in the center, with control consoles on the western wall nest to a large machine, On the northern wall is two large machines and on the eastern wall is two standing computers. Next to the two computers at the north east corner is a door to another hallway, forking east and north. Taking the hallway east leads down a flight of steps to another loud large generator room, on the northern wall is a door leading to a "Raider Workshop" work room. This room has a work bench on the norther wall a makeshift anvil at the corner of the east wall and north wall. With metal shelves on both the east and west wall. The southern room has a "Tool cabinet" on the western wall, metal shelves and a locker on the south wall.

Taking teh northern stairway up one floor leads directly o the foyer hallway of a Metro station in Georgetown. This Metro station is completely collapsed with only the hallway and gated entrance accessible.

The place is infested with Molerats and also lit hevelly by barrel fires. Georgetown metro has unique building next to it.

n underground location between the Anchorage Memorial (close to Dukov's Place) and Georgetown, inhabited by mole rats and raiders.

--> The sewer has a straightforward layout, connecting an extensive sewer on the Potomac end and a collapsed metro station on the Georgetown terminus. There are plenty of supply caches scattered in the tunnels, filled with molerats and raiders hunting them.

The metro tunnel connecting the sewer to the Georgetown network and water system also houses Rocksalt's base of operations.

Notable loot

 * Dean's Electronics when you first enter the subway area from the south. Deal with 3 raiders (1 behind sandbags, other 2 in corridor), enter the corridor, turn left, and enter the small room on your left. The book will be on the right corner behind toolbox (near ‘generator’) (A).
 * Be careful when coming up to the raider's hideout. There are several mines scattered on the tracks, so either shoot them and possibly cause damage to one of the raiders or disarm them and keep them for yourself.
 * There is a safe with some worthwhile loot amongst the raiders (B). You must either loot Rocksalt's key off Rocksalt(C), or pick the lock to open it. It is in the sleeping room of the raiders. Rocksalt's key also opens up a storage room further on in the area. There is also a pre-War book on top of the bookcase.
 * There is a power fist in the terminal storage room, in a metal box (D). In a wooden crate with some burned books is also another pre-War book.
 * There is a workbench in the top right room on the local map, along with tools, scrap metal, and junk.

Related quests

 * The Wasteland Survival Guide: You are suggested to visit this location during Moira Brown's quest, to test Moira's Repellent Stick, which is smeared with mole rat repellent, on a number of mole rats.

Appearances
The tepid sewer appears only in Fallout 3.

Bugs

 * There is a rare bug that when you unlock the door using Rocksalt's key and open the door there will still be a barrier like the door was never opened in the first place. The only way to fix is reload a previous save.
 * Another glitch is when Rocksalt's raiders kill the mole rats, a spurt of blood may appear where they were killed and continues to shoot blood. Found in the room with the generator.
 * If you complete the quest then steal the Repellent Stick (hidden upstairs in Moira's shop) it will be irremovable as it still counts as a quest item but will not weigh anything. You can use it as a weapon but it cannot be dropped and will not appear in your inventory when checking in a container or a shop.
 * After entering the Tepid Sewers an Enclave deathclaw will immediately spawn in front of you, then die in a matter of seconds. This is possibly somehow connected with the deathclaw control scrambler which basically turns Enclave deathclaws into short-term followers.
 * Once you go into the sewer it's possible you won't be able to get back out due to a door lock glitch.
