The Jander or Jandar (as it is called by the locals in Murree, Pakistan) is a water driven mill that was commonly used in the mountain areas of the Murree Hills where water is abundant. Janders were very common during the barter economy era but have been replaced by diesel and electric mills which are more efficient and are able to operate all year, as they are not dependent on seasonal rains. They are also more accessible than janders, which had to be located on the banks of running streams, generally some distance away from where people lived. Some janders are still operating in the foothills. The local tribes of the Murree Hills such as the Dhanyal, Abbasi and Satti were the main users of these traditional mills.
