Water treatment

Water treatment is a type of room that can be built throughout a given vault in Fallout Shelter.

Overview
Water treatment rooms create water resources for a vault, and are affected by the Perception stats of residing vault dwellers working within them. These rooms can be built and utilized immediately, and are a crucial element towards maintaining a successful vault.

Resource modifiers
Vault dwellers with higher Perception stats will produce additional water resources, which is crucial as a vault increases in population, as water demand will continue to rise.

Production/cost
Water treatment rooms will gain a +2 production bonus for each connected room of the same type, with upgrade costs being 25% cheaper for double rooms, and 35% cheaper for triple rooms, all in comparison to building multiple single rooms throughout a vault.
