Abstract: A light weight portable device for sterilizing harmful bacteria containing water by the use of commercial alternating electric current. The components of the device are removably connected to one another, and may be separated and stored in a compact arrangement when the device is not in use. The device is particularly adapted for supplying potable water from contaminated water in areas that have been subjected to a disaster such as a flood, earthquake or the like. The components of the device may be readily assembled into a usable unit by persons having little or no mechanical skill.
