What is sand abstraction

Sand abstraction is a method of drawing water from sand rivers for domestic, livestock and irrigating small gardens using different systems.

Water storage in sand

Sand consists of small stone particles that originate from stones and rocks being broken down by the effects of sunshine, rains and temperature variations.
Voids, which are empty spaces, are always found between sand particles. When dry riverbeds are flooded by rains and flash-floods, the air in the voids is pressed out by the water because it is heavier than air
Coarse textured sand has larger voids that get saturated much quicker than fine sand. Therefore, much more water can be extracted from riverbeds containing coarse sand than from riverbeds with fine sand.
Fine textured sand has tiny voids that get saturated slowly with water. Only about 10% of water can be extracted from the volume of fine sand.
Coarse textured sand has larger voids and is therefore saturated much quicker than fine sand. The volume of water that can be extracted from coarse sand is about 35% of the volume of sand
