Good for developed or developing countries, the wind pump described in How to Build a Wind Pump 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. This system does not generate electricity. The turbine is 700 mm diameter and the turbine head plus rotor weighs less than 4 kg. In a light-to-moderate wind it should pump about 1000 litres a day with a head of 4-5 metres. If you have good engineering skills and equipment 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.
