Late Islamic water collection systems on Failaka Island: Preliminary results of the Kuwait–Georgian Archaeological Mission in 2018–2019

Archaeological investigations on Failaka Island, conducted by the Kuwait–Georgian Archeological Mission, have recorded a variety of sites dating from different time periods, from the Bronze Age to the late Islamic/modern period. The largest proportion of recorded sites consist of late Islamic seasonal settlement structures found in the north-eastern part of the island. It is possible that they were connected to fishing and associated activities such as stock-farming and agriculture, which is confirmed by the results of palynological analysis. These sites are divided into two chronological phases: one from the seventeenth to eighteenth century and the second from the nineteenth to the first half of the twentieth century. In 2018, excavations at the water collection systems within these settlements began. The results gathered so far indicate that there were two kinds of well structures. The first are interpreted as shallow filtration well pits; the second are deep wells used for collecting water from deep underground. Both systems were used to collect rainwater, which was then filtered and stored. Marine and freshwater forms of algae were found in the basal sediments of the pits, which offers evidence for the accumulation and filtration of water.
