Over one billion people in the world do not have access to clean water.  Water-related diseases constitute 80% of sickness and is the leading cause of death all over the world.  Therefore Playpumps International has created a mechanism that resembles a playground toy for many third world countries.  The Playpump will be installed near schools and can gather about 1,400 liters of water per hour at 16rpm from a depth of 40m.

Is this child labor?  Not necessarily because these kids would otherwise have to fetch water from far distances without the Playpump.  This is also a good way for children to have fun at the same time.  There are advertisements placed on the water tank that pays for the maintenance of the Playpump.  In the U.S., a new brand of bottled water will be released called Love One.  The proceeds from the purchase of these water bottles will go towards the Playpump.
