The water treatment is a room built in Fallout Shelter.


The water treatment room creates water for your vault, and is affected by the Perception stat of the vault dwellers working there. It is one of the facilities available at the start of the game.

Water productionEdit

To increase the speed at which water is produced; Place dwellers with better Perception in this room.

Your water demand will go up the more dwellers you have. If its supply runs low, dwellers will start to become irradiated.

Production/cost Edit

The water treatment, like other rooms, gains a production bonus from being connected to another of the same type and level. The room will gain a +2 production bonus for each connected room. Upgrade costs will be 25% cheaper for a double room and about 34% cheaper when upgrading a triple room vs upgrading 3 single rooms.
