Windpumping is an established technology, with over one million windpumps in use worldwide. A windpump needs no fuel, little maintenance and it usually lasts 20 years or more. Designs exist which are suitable for small-scale local .manufacture. The aim of this handbook is to help potential users and decision makers take advantage of the benefits that windpumps can offer. This handbook was first written for a windpump familiarisation seminar held in Nairobi in November 1986. The seminar was organised and presented by I.T. Power, hosted by the Ministry of Water Development of Kenya and funded by the Overseas Development Administration.
