- Wied ta' Sant' Andrija

Wied ta’ Sant Andrija is an artificially constructed reservoir, intended for water storage and flood prevention, located in western Malta within Is-Siġġiewi. The reservoir is constructed out of cement and covers an approximate area of 1,200m2. The site is accessible to the public by a surfaced road. A culvert was present on an active surfaced road, channelling water to the reservoir indicating it is being used as a flood prevention measure. The site is surrounded by surfaced roads and residential dwellings, however, active agricultural land is present to the north. It is unclear if the reservoir is being used for irrigation as pipelines were not visible. Within the basin of the reservoir, a sizable population of rudimental species were present, whilst within the reservoir a minute population of Rumex conglomeratus was present. The site is not protected under any legislation
