Infiltration trenches
Infiltration trenches are excavations in the ground 2 to 3 meters long and 1 meter wide and deep, useful for reducing surface runoff and erosion. They are also used as part of rainwater treatment and harvesting systems, since the soil and porous materials in the trench can retain and filter pollutants from rainwater before they infiltrate into the soil.
