To be used in sub-horizontal trenches and vertical wells, and to perform a dual function, namely, promoting the uptake of rainwater infiltrated into the soil, whose flow will be initially conducted in a horizontal direction, promoting, then its vertical diffusion along the substrate of the ground to recharge the ground water and the local aquifer, thus helping to minimize the surface flows, becoming an important tool for flood prevention and environment protection, recharging thus the water sources.
