1.1 billion people do not have piped water supplies—they often collect it from unsafe sources and carry it home. This sustainable, household device uses UV disinfection, powered by a bicycle, to produce safe drinking water.
Patent-pending. Inventors: Paul Berg, engineer with CH2M HILL, Inc. and Chris Smith engineer with Intellegration LLC.

  • As an aquatics director for over 30 years, I've worked with many forms of disinfection for our swimming pools, including chlorine (liquid and granular), bromine, ozone, and ultraviolet light. I believe ultraviolet light is by far the most effective, so I am excited to see the way you are applying that technology to make water safe to drink for people who might have trouble getting clean water. Great idea. I've seen most of the videos and yours is the best.

  • Dr. Berg - The world needs more people who are concerned with the needs of the developing world. You are obviously a creative and dedicated humanitarian, not a greedy entrpreneur and I wish you the best. - FHW

  • Actually 25 watts for a minute is pittance

  • Can third world people afford to lose anymore weight?

  • I never said UV light distills water, now did I?

  • Paul great job!

  • Can your bicycle be used for transportation after disinfecting the water? How much does the unit cost? How long do the ultraviolet bulbs last? Have you considered the use of SODIS system which costs nothing and produces clean water?
