It operates in a similar way to a windmill-driven water pump. The PlayPump water system is a like a playground merry-go-round attached to a water pump. The spinning motion pumps underground water into a 2,500-liter tank raised seven meters above ground. The water in the tank is easily dispensed by a tap valve. According to the manufacturer the pump can raise up to 1400 liters of water per hour from a depth of 40 meters. Excess water is diverted below ground again. The storage tank has a four-sided advertising panel. Two sides are used to advertise products, thereby providing money for maintenance of the pump, and the other two sides are devoted to public health messages. There are more than 1000 PlayPump systems in five countries of Sub-Saharan Africa, providing clean drinking water to more than 1 million people in need.
