The water wheel in the entrance hall was driven by the cave river and transported some water of the river up into a water pipe. This was the water supply of the village Aggitis.
The huge first hall was used in the 19th century to install a water wheel, which pumped water up into a water pipe. At this time the first short tunnel was built to access the first hall. The water was drinking water for the town and irrigation water for the nearby tobacco fields. There was a six kilometre long channel, which was also built at this time.
