A simple UV zap chamber made from PVC pipe locally available components allows treatment of large quantities of water at an extremely low cost. Filtration to remove solids is extra and depend on volume of water and what type of pumping system or pressure is available. Specify either AC or DC current to run the 15 watt florescent light inside the chamber. This ultra violet light source (the 235.7 nm range) breaks DNA linkage of harmful bacteria and reproduction is made impossible. You can drink the water without the threat of diarrhea or other more dangerous bacteria induced side effects. We supply the entire unit bulb, casing, wires and DC ballast.
