Cavorting on a roundabout has always been fun for children. Now pure, clean borehole water can be pumped into water storage tanks while the playground roundabout equipment is in use. The Play-Pump is a specifically designed and patented playground roundabout that drives conventional borehole pumps, keeping costs and maintenance to an absolute minimum, while entertaining the children.Basically, as kids spin around on the merry-go-round, water is drawn out of the ground into an easily accessible storage tank.
To cover maintenance costs for the Play-Pumps, advertising is sold on the sides of the storage tank. The advertising space can also be used for educational campaigns about HIV/AIDS and other issues of concern. Trevor Field, one of the principals behind the Play-Pump, made his fortune in outdoor advertising, so I guess the billboard aspect of the project is no surprise.
In a report yesterday afternoon on the Play-Pump, "The World" called it "a merry-go-round with a mission," giving kids both something to play on and an easy-to-tap supply of clean water. World Bank DevNews has some photos and this quote from Field: "There's nothing quite like children's power as a pure energy source."
According to an article in Engineering News, more than 300 have been installed across South Africa and the first ones have been in use for more than a decade.
