Some Qanats are over three thousand years old, and are certainly listed in guidebooks.  There is a Qanat system in Persia that is UNESCO listed (https://whc.unesco.org/en/list/1506/)

“Modern” Qanats/Karez are still often hand dug, not with modern tunneling equipment. The World Bank funded the refurbishment of many in Afghanistan, usually these were done with traditional methods, and they are the main source of water in many areas.
