Pumping on your feet — the Treadle pump
Say you are a poor farmer in a rural area in a developing country. Then your best bet out of poverty is to make more money. From where? From the field. You need to grow stuff. And because growing things need water, you need access to water. Water is money.
One options is to wait for the rain. It is a stressful option, because the rain might come too late, it might not come at all, or it might come all at once, all of which are bad. The other options is to take control over the water you need. That means getting a pump. What kind of pump? One that is affordable, available, and repairable. Ergonomic, and easy to operate.
The treadle pump fulfills all these demands with flying colors. It is a foot-powered water pump widely used in Asia and spreading in Africa. It consists of two metal cylinders with pistons that are operated by a natural walking motion on two treadles. It is ideally suited for use on small farms which draw irrigation water from 1-7 m deep. Because it is a suction pump, the depth is limited to about 8m.
