Agriculture in Wied Hazrun flourished for centuries. Together with an adjacent site called Il-Qattara, both areas are of historic interest due to surviving remains of irrigation systems dating from ancient times. The name Qattara is a Semitic word meaning trickling water. The system in which the Qattara operaes is called il-Qanat, and could have been operating in Malta as early as Phoenician times.
The Romans found this water system and exploited it for other than agricultural purposes. On the opposite side of the valley lie the preserved Roman baths, mentioned earlier in Ta’ Baldu territory. The valley of Hazrun still enjoys a stream derived from the Qattara system, maintained and inherited by several generations of hard working ancestors.
