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, the player can check the entries of the Front Office Terminal which will update the map. Around the corner is a toilet with first aid. Next to the stairs is a locked door (advanced) which some goodies behind it. The player can go up to the roof via a ladder, and there is a cache of goodies behind a locked safe (expert) and a terminal (novice).

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, there is a turret to the left and a locked door (novice) with some ammo boxes behind it. To the right (the one with the Picket Fences skill book), where there is a computer terminal and a locked safe (expert). 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.

The third option is a mixture of both: Hack the terminal, deactivate the turrets, go downstairs, open the door and kite all the already active mirelurks into the room with the turrets. Have your companion block the mirelurks at the bottom of the stairs, head back to the terminal and re-activate the turrets. No XP though, but maybe easier than to fight them all, especially playing on harder levels.

Notable loot

 * Picket Fences #5 (unlocks patio furniture in the workshop) 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.
 * Super mutant heavy gauntlets can be found in the shack to the right of the main entrance of the water plant.
 * Super mutant bladed helmet can be found on the floor of the highest shack. A fusion core can be found in the same shack.

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.
