Water (Fallout Shelter)

Water is a resource in Fallout Shelter.

Overview
Clean water is hard to come by in the wasteland. Running low on water will make your dwellers take radiation damage due to the consumption of polluted water.

Water production
There are three basic sources of water:
 * Water treatment rooms, available from the start.
 * Water purification rooms
 * Nuka-Cola bottlers

Water can also be acquired through lunchboxes.
