Alberca

An alberca is a water deposit for irrigation. Ours is right trapezoid shaped, with dimensions of the three right-angled sides being 6.05m, 7.30m, and 4.55m.

This gives 1cm in height a volume of about 403 litres of water.

The depth of over 5m gives the overall volume of the alberca in excess of 200,000 liters.

While the irrigation pipes are open the albeca drains by 30cm an hour, resulting in a watering flow rate of 201.5liters per minute.
