How to build a wind pump

Good for developed or developing countries, the wind pump described in this book can pump rainwater, greywater, river, pond or well water for irrigation, aerate a fish pond, run a water feature or even be a bird scarer. The turbine is 700mm diameter, and the head plus rotor weighs less than 4kg.

In a light-to-moderate wind, it should pump 1000 litres per day, with a head of 3-5 metres. If you have engineering skills and kit, you can fabricate nearly all of the system yourself; if you get all the parts manufactured, it’s not much more complicated than DIY flatpack furniture.
