“Be mindful of taking care of yourself without excesses.” In the case of Playpumps® International, an NGO based in Johannesburg, South Africa, coupling a not-for-profit with a for-profit company produced the needed incentive to bear truth to the idiom that one person, one simple idea can really change the world. Trevor Field and his partner, Mark Melman, former executives in the outdoor advertising industry, have done just that. With the invention of the PlayPump® water system, government agencies, NGOs and for-profit business have converged to address the disturbing reality that over one billion people lack access to clean water. According to Field, “I remember when I first looked at this water pump; I could never imagine that this is something that could possibly change the world. I remember when I came up with this idea and everyone was laughing. They’re not laughing now.”
