- Malta Freeport

Malta Freeport is an old artificially constructed reservoir, intended for water storage and flood prevention, located in southern Malta within Birżebbuġa. The reservoir was mechanically excavated and has had its border extended via the use of limestone blocks. The site covers an approximate area of 1,370m2. The reservoir is accessible to the public by surfaced roads. A car park lies to the north and south of the site, a boatyard lies to the west whilst offices are located on the east. The reservoir is currently being used to store water from the nearby road surfaces, as a flood mitigation measure, and there is no indication if it is being used for irrigation. A small number of Ficus carica and Salix alba are growing within the basin.
