The water purification is a room built in Fallout Shelter.


The water purification room is the Tier II version of water generation infrastructure. Compared to the Water treatment room it produces a moderately larger amount of water, however it is significantly more expensive. Like most other buildings, the water purification room can be combined into a 3 wide building, increasing production and allowing more workers. It requires 80 dwellers to unlock.

Water productionEdit

To increase the speed at which water is generated, place dwellers with better Perception in this room.

The water purification room, like other rooms, gains a production and upgrade cost bonus from being connected to another room of the same type and level. The rooms 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.
