Weston Water Treatment Plant

The Weston water treatment plant is a location in the Commonwealth in Fallout 4. The player character discovers from Supervisor White in Graygarden that the water has gotten a lot worse during the quest Troubled Waters and is sent to investigate. The Sole Survivor discovers that the facility has been overtaken by super mutants.

Layout
The facility is a water treatment plant with a series of ring-shaped open-air basins containing water on the eastward side. Around and across these basins, super mutants have constructed a series of walkways and are patrolling them. These mutants are armed with rocket launchers and sniper rifles. There is at least one suicider with a mini nuke.

Inside the facility, there is not much on the first floor. The player can go up to the roof via a ladder, and there is a cache of goodies behind a locked safe.

Down the elevator, the player character is lead to a series of rooms with locked doors. These doors can only be opened by pressing a large red button beside them, and they can only be opened when the button is illuminated red. If the button is not lit, it means the section beyond is flooded. To traverse the level, the player character must activate a series of pumps to drain sections. This will expose the Sole Survivor to attacks from mirelurks that are living in the water treatment plant. The lower levels are also guarded by a series of turrets. Upon exiting the elevator to the lower level, the player character can go into a room to the right (the one with the Picket Fences skill book), where there is a computer terminal. This terminal gives the option to disable all automated turrets in the section. However, the auto turrets will target mirelurks as well as the Sole Survivor. This gives the player character the choice to fight the mirelurks unassisted, or to have the turrets help against the mirelurks, but have to fight turrets as well.

Notable loot

 * Picket Fences - In the metal office overlooking the generator room, before descending to the main treatment chamber.
 * Possibly the largest repository of mirelurk eggs in the Commonwealth. While they are value 0, they do have other useful purposes.

Appearances
The Weston water treatment plant only appears in Fallout 4.

Bugs

 * Be careful with the exit elevator that becomes available when the mission is over. It is possible to get stuck inside permanently, forcing one to reload a previous save.
 * You are unable to hijack the turrets using the Turret override program as there is no 'load holodisk' functionality.
