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. The trailers and shack in the very middle of the basin have floor traps in their entrances, including a tripwire-activated missile launcher.

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 led 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 - a total of ten.

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 room with the Picket Fences skill book), 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. If you want the XP for the turrets, you can then reactivate them and fight them once the mirelurks are gone.

Behind the scenes
Weston Reservoir is located west of this site in real life. The site itself is on top of an aqueduct from that reservoir and is the former site of Norumbega Park, an amusement park that fell out of popularity after World War II, and its namesake, Norumbega Tower.

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.
 * If you're "stuck"(elevator or pump control switch won't work) open console ` and type "coc WestonWaterTreatmentExt" then "resetinterior 6fe2f" without quote alternative is to reload a previous save however it seems the elevator and pump control switch won't work until you relaunch to game.
 * On appoach it is possible that a Brotherhood of Steel Vertibird will attack the Supermutants outside the facility, the Vertibird will fly into the raised section of highway above the facility repeatedly and then crash.
