Quick walkthroughEdit

Side Quest: Fix the Necropolis water pump
Get some junk from the Necropolis sewers.
Go to the Watershed.
Repair the water pump.
Reward: 2500 XP, if the super mutants did not attack Necropolis
Reward: 1000 XP, if the mutants attacked

Detailed walkthroughEdit

After talking to the underground ghouls of Necropolis, travel to the watershed area and then enter the Necropolis sewers that are being guarded by Larry. In the eastern end of this section of the sewers lies a pile of junk. It is essential to the completion of the quest. Alternatively, junk can be more easily acquired from the Hub, found in a crate in the south-east corner of the weapons supply shop of Jacob in the Hub's Old Town.

The Vault Dweller then needs to approach the water pump and use their Repair skill to fix the pump. A successful skill check will fix the pump (a tool will help greatly). A critical failure will remove the junk from the Vault Dweller's inventory and deal 1 point of damage to them.

Then the Vault Dweller can rest easy that they have saved the ghouls from death. For a while, anyway.


  • 1000-2500 XP for repairing the pump.


  • An alternative way to get this quest is from Set, if the player hasn't killed the Master yet. If the Vault Dweller has already searched Vault 15 and are in possession of the "junk", Set will have his surly minion, Garret, fast travel with the Vault Dweller to the water pump. The Vault Dweller is then forced to repair it at gun point.
  • The game only checks having any junk in the inventory, allowing one to use any such item (such as from Jake's house in the Hub) to complete the quest.
  • If the Vault Dweller returns to the leader of the underground ghouls after finding the Junk, but before fixing the pump and talks to him, they will receive three skill books.
  • The quest can still be completed for 1000 XP if Necropolis has been attacked by the super mutants.
