This paper by A Jagadeesh of RMK Engineering College, describes the design and testing of a portable, low-cost, and low maintenance solar disinfection unit, that can provide potable water. This system was tested with bore water, well as well as with waste water. In 5 hours, the unit eradicated 99.99% of the bacteria contained in the water samples.

This unit can provide about 6 liters of pure drinking water and larger units can be fabricated for providing safe drinking water at a community level.
