Yazd is famous for its qanats (underground aqueducts) and this museum, one of the best of its kind, is devoted to the brave men who built them. Located in a restored mansion with a visible qanat running underneath, the museum offers, through a series of photographs, exhibits and architectural drawings, a fascinating glimpse into the hidden world of waterways that have allowed life to flourish in the desert.
The uniform of the qanat builders shows an early form of Personal Protective Equipment (PPE), with padded cotton hats and white-coloured clothing that was both luminous in the dark and would act as a shroud in the event of a fatal accident.
The museum, which charts the 2000 years that Iran’s unique irrigation system has been in operation, describes the drilling of mother wells (which can reach a depth of 300m, such as the qanat near Mashad) and the use of water distribution clocks. These clocks (basically a bowl with a hole in the bottom) helped to mark out the 15- or 20-minute shares of water purchasable by householder or farmer.
