What effect do infiltration basins have on stormwater runoff?

Infiltration basins play a crucial role in managing stormwater runoff by promoting the absorption of water into the ground. When stormwater runoff enters these basins, the design encourages water to percolate through the soil layers, which not only reduces the overall volume of runoff but also helps recharge groundwater aquifers. This process effectively diminishes the risk of flooding and erosion associated with rapid surface water flow, leading to better water quality as pollutants are naturally filtered by the soil.

The basins are specifically engineered to retain water temporarily, allowing time for the infiltration process to occur. By absorbing water rather than allowing it to flow directly into storm drains or nearby water bodies, infiltration basins mitigate the impacts of stormwater runoff, making them an effective Best Management Practice (BMP) in stormwater management systems. This functionality directly addresses the goal of managing stormwater in an environmentally friendly way, contributing to sustainable water resource management.
