Before the Great War, the MacDougal-Bernard Co. purified and bottled this water, intended to be used in an emergency, for the federal government and its assets, especially the military.
Characteristics[]
A can of water, which has been cleansed of radiation. It restores 40 health.
Production[]
Purified water is produced at any populated settlements allied with the player that are equipped with water pumps or water purifiers.
Purified water is added to the workshop inventory when the settlement update timer activates every 24 in-game hours (72 real minutes, if the player character doesn't accelerate the passage of in-game time by sleeping). Entering workshop mode at a settlement pauses the update timer for that settlement, while in-game time continues to pass, so the exact time of the update tends to shift at settlements that undergo construction.
The settlement timer also controls when drinkable items are consumed from the workshop at the settlement, at a rate of 1 per human population. This consumption takes place before the purified water is deposited at some settlements, and after deposit at others. Drinkable items stored in containers other than the workshop will not be consumed.
Purified water will not be added to the workshop if more than 5 drinkable items (including dirty water and alcoholic beverages) are present. This cap increases by 1 for every four population. Regular collection of excess purified water is therefore necessary to continue production.
Purified water can be farmed as a great source of caps, due to its unlimited supply.
Survival mode[]
In Survival mode, purified water satisfies the Sole Survivor's thirst.
Additionally, purified water can be generated by using the "Fill Bottle" option when next to a water pump, water fountain or sink if there are empty bottles in the player character's inventory. All variants of empty bottles can be used for this purpose.
Four can be found at the water filtration caps stash located due east of Sanctuary Hills.
Three cans can be found in Barney Rook's basement bunker in Salem.
Two cans can be found inside the marked toilet in the Fort Strong armory bathroom.
Two cans can be found inside the Castle armory, after completing the quest Old Guns.
Notes[]
Unlike the bottled water featured in Fallout 3 and Fallout: New Vegas, the water in Fallout 4 either comes in cans or cartons.
There is a random encounter in which the Sole Survivor will encounter a water beggar and will have the option to give the beggar some purified water to ease their thirst.
Behind the scenes[]
It is based on real cans of emergency drinking water bottled by the MacDonald and Bernier company located in Boston and issued by the federal government in 1953.[1]
