During archaeological digs on the island of Crete, various varieties of conduits have been found. In combination with delivering water, they spread out water which accumulated from storms or waste. Stone and clay were the materials of choice for these conduits. Whenever terracotta was utilized, it was usually for waterways as well as water pipes which came in rectangular or spherical patterns. There are two good examples of Minoan terracotta conduits, those with a shortened cone form and a U-shape brand statue which havenâ€™t been seen in any civilization ever since. Knossos Palace had an state-of-the-art plumbing network made of terracotta conduits which ran up to three meters below ground. The clay water pipes were also used for collecting and holding water. To make this possible, the piping had to be created to handle: Subterranean Water Transportation: Itâ€™s not really understood why the Minoans required to transport water without it being seen. Quality Water Transportation: The conduits could also have been utilized to move water to water fountains that were different from the cityâ€™s normal system.
