The aqueduct was constructed in the Minoan Period. The remains that show one part of the aqueduct was constructed with closed tubes and channels from sculptured stone. It was constructed in order to filter the water of the spring before it enters the conduit. The water was filter by a multi-layer terracotta device. The filter had conical shape with 0.8 m height, 0.62 m base, 0.22 m upper diameter and a total volume of 0.136 cubic meters. Water filters, long-distance conduits and public distribution systems were connected with domestic water supply systems and reservoirs or similar filtration devices, for better water quality. A stone cistern was used for the pre-processing of water and mainly for the removal of sediments and the main cistern used for its storage. Its total length was 1,4 km.
