Pore irrigation: an ancestral system brought up to date
WEPOT s a small Swiss company that is revisiting an age-old irrigation system called "olla" or "jar irrigation". Even today, this system is among the most efficient and allows to save 70% of the water used for irrigation.
WEPOT ollas can be used for indoor plants, vegetable gardens or larger farms (1 hectare). Filled with water once a week, the ollas provide the plant with water according to its needs as its roots gather around the clay pot, by porosity. Thanks to the deep watering, the proliferation of diseases and weeds is greatly reduced.
WEPOT's objective: to develop a porosity irrigation system for market gardens in the world's most arid environments. Today, the company is in an expansion phase and is approaching its break-even point.
It is difficult to cite the exact origin of this historically very important technique in Asia, Africa and the Middle East. It is mentioned in texts about agriculture in China dating back more than 2000 years!
