Yazd University is pioneering water conservation efforts by implementing a novel subsurface irrigation system in a designated section of its green spaces. This project, led by two faculty members, promises significant water savings and improved efficiency.
Dr. Mohammad Ali
Sadeghzadeh, a faculty member at the Department of Physics and one of the
project leads, explains the system's operation: "Water is delivered
directly to tree roots through perforated PVC pipes buried 50 cm underground
adjacent to the trees. These pipes are covered with plastic fabric to prevent
clogging."
Highlighting the system's advantages, Dr. Sadeghzadeh emphasizes its potential for water conservation: "We anticipate a 40% reduction in water usage compared to traditional methods. Additionally, the system eliminates the need for filtration and water pumping systems, facilitates fertigation – the application of fertilizers through irrigation – and minimizes disruption to landscaping operations.”
Dr. Hassan Hosseini-Nasab, a faculty member of the
Industrial Engineering Department, further details the technology's origin:
"This method represents the latest innovation by Iranian researchers. The
initial research was conducted at Yazd University and subsequently approved by
the National Agricultural Engineering Research Institute."
