Abstract
The traditional water mills have low output with primarily use of grinding. The up gradation and improvement of these water mills is an effective and sustainable way of meeting the energy needs of a major section of the hilly people. This study discusses the case study of standard water mills developed in order to cover the entire range of water mills sites in Uttaranchal. Based on the site data available, 1 standard water mills have been designed, developed and tested for their performance. The developed water mills at Kherola village near Bhimtal, district Nainital have been found efficient. The status of water mills, energy situation in Uttarakhand, impact of water mill upgrade and the developed system have also been discussed.
