A Constant Trickle

tunnel.jpg

We are looking here at a small part of a large underground system of tunnels collecting water for irrigation purposes. It is said that these tunnels were possibly first built by the Moors, some 900 years ago.

The amount of water that this tunnel system extracts out of the mountain seems insignificant. There is but a mere trickle, albeit constant. But, just for a minute, imagine a trickle of water that amounts to approx. 5 litres of water every 3 minutes, trickling away for 24 hours. That gives you an astonishing 100 litres per hour, or 2,400 litres every day.

Add up your numbers, and you’ll have 878 tons of water in a leap year, and not much less any old year but leap. Seems that the Arabs in those days knew a lot about the large effect of many little drops of water.

The photo was taken near Felanitx, Mallorca, Spain. The date: February 23rd, 2008. The time was 13:41:21.
