Eight main irrigation channels, or acequías, funnel water from the River Turia, which is then carried – by gravity – along a series of smaller branches, which distribute the water to thousands of tiny plots across the fields. The amount of water each plot receives isn't measured in terms of volume but rather on how well the river is flowing. The unit, known as a fila (from the Arabic word meaning "thread"), represents an individual's right to a proportion of the water over a period of time; the irrigation cycle usually lasts a week, but when the river's level is low, the cycle is extended.
