infiltration trench

An infiltration trench is a drainage feature designed to manage stormwater runoff by allowing it to soak into the ground. Typically filled with gravel or rock, these trenches are dug into the soil to collect excess water from rain or melting snow. As water flows into the trench, it gradually filters through the material, replenishing groundwater and reducing surface water flooding. Infiltration trenches are often used in urban areas to minimize the impact of development on the natural water cycle and protect surrounding ecosystems from pollution and erosion.
