Description of technology
Improved Watermill (IWM) is hydro based technology which converts the potential energy of water into mechanical energy. This mechanical energy, with the use of conveyer belt and pulley is eventually used to operate small capacity mills and for generating electricity in the rural areas.
This technology can be used in the hilly areas nearby a stream where flowing water and a suitable head can be accessed.
Traditional watermills (TWM) are widely operated in rural areas of Nepal and this IWM technology is the improvement of TWM hence the technology is not very complicated. Generally, with basic operation and maintenance training, mill owner can operate IWM and can perform maintenance.
