MAL029 - Ta' Qali 3

Description

Ta’ Qali is an old abandoned quarry that had been turned into a water reservoir, located within the former Flower Power gardening complex in the outskirts of Mosta. The site is accessible by a dirt road, however, it is located on privately-owned property, and covers an approximate area of 2,720m2. The quarry is surrounded by abandoned agricultural land, abandoned buildings and derelict greenhouse structures. Due to the topography of the area alongside an individual pipeline entering the reservoir, it is assumed that apart from precipitation, the reservoir is being filled by surface runoff. There is no indication that the water accumulated is being used for irrigation. The quarry was completely submerged in water and dominated by two species; Typha domingensis and Cyperus longus subsp. bandius. The site falls within the Ta’ Qali Recreation Area and the Ta’ Qali Action Plan Area. The future of the site is unclear due to the reservoir being part of a proposed development for the construction of a sports village.
