GOZ012 - Tas-Seqer Reservoir


Tas-Seqer is an artificially constructed reservoir, intended for irrigation and water storage, located in western Gozo within the rural village of Għarb. The borders of the reservoir have been constructed out of cement, beneath a rubble wall. The reservoir covers an area of approximately 1,080m2. Access to the site is via a dirt road, however, it appears to be located on privately-owned property. Since the site is predominantly surrounded by agricultural land, the reservoir is likely to be used for the irrigation of these fields. Ducks and aquatic insects were noted during the field survey. The site is not protected by any legislation.
