MAL059 - Il-Qbiela


Il-Qbiela is a large and elevated, artificially constructed reservoir, intended for irrigation and water storage, located in western Malta within Dingli. The reservoir was constructed in the 1980s out of cement and limestone, is 8.5 metres high and covers an approximate area of 1,040m2. The site is not accessible to the public as it can only be accessed through privately-owned agricultural land. The reservoir is predominantly surrounded by agricultural land with numerous pipelines scattered throughout adjacent fields, indicating that it is likely being used for irrigation. Within the basin of the reservoir, Ceratonia siliqua and Ficus carica are present. The site is not protected by any legislation.
