The old civilization is a typical example of the sustainable society, which may provide us with much information on it. Machu Picchu, one of the towns in Inca, was surveyed in 1999 and 2000 on the system of water supply and drainage to investigate sustainable systems which it might own.Machu Picchu had two springs for water resources. Water distribution was done with open channels made by stone. Water distributed to the town was utilized at a series of 16 fountains in cascade use and probably in time sharing. The first to the third fountains would be for ritual and others for drinking and irrigation. Machu Picchu had neither drainage nor wastewater treatment systems. The population in Machu Picchu was estimated around 2400 from the water supply capacity. The society of Machu Picchu was under severe restriction on water supply, and not safe on drinking water.
