  • Ultraviolet water sterilization
    Patent number: 9199864
    Abstract: Technologies are generally described about a water sterilizing apparatus. In some examples, a water sterilizing apparatus may include a surface water collection apparatus configured to collect surface water; a pipe operably coupled to the surface water collection apparatus and configured to allow water collected by the surface water collection apparatus to flow through the pipe; and a multiple number of UV lamps arranged along an inner wall of the pipe. Further, the water flowing through the pipe is sterilized by UV light from the multiple number of UV lamps.
