In developing countries the treadle is changing lives by simplifying the process of moving water, without electricty.
As it makes conventional agriculture more efficient, the treadle water pump is a brilliant idea that can be applied to low energy aquaponic gardens to take them entirely off the grid. More dependable than solar panels, wind power and batteries, the treadle is another remarkable means to gain self sufficiency.
Ebb and flow systems do not require much energy as they only pump periodically, every day. But when there is no electricty, just a modest amount of effort, as in this case, makes it possible to function when otherwise no power would be a showstopper.
It would be but a simple task to treadle water into elevated plant beds for but a minute, 4-6 times per day. Gravity returns the water after coursing through a series of soil-less beds, which make use of natural forces to distribute water over large areas. After water from fish tanks is pumped to the plant beds, it returns to the tank purified of ammonia and charged with oxygen.
CODEP is doing some great work in Haiti using the pump to help reforestation and farm development. Here you can download a step by step instructions to build your own treadle. Lots of happy smiling faces on the CODEP website. India is one country that is greatly benefitting by the treadle, where companies like IDE and SK Industries help turn a million dreams into one big reality.
