INFILTRATION CONTROLS
A family of structural controls in which a specified volume of stormwater (e.g. treatment volume) is retained on-site and allowed to infiltrate into the soil and evaporate rather than being discharged. These controls reduce the stormwater volume and pollutant load. Infiltration controls include basins, exfiltration trenches, French drains, and treatment swales.
Dry Retention Systems (basins) are infiltration systems that are excavated into the ground. Typically they are vegetated to minimize erosion and the roots help maintain the permeability of the soils.
Exfiltration Trenches / French Drains are shallow, excavated trenches in which stormwater is stored in perforated or slotted pipes and percolates out through the surrounding gravel envelope and filter fabric into the soil. In South Florida, these systems are called French drains.
