Retention Wells are used to safely convey impervious runoff (roofs, driveways, patios) during rain events. Its a form of bioretention that uses the soil on site to store the runoff underground and then discharge through an outflow pipe when full. The final product is reduced runoff. It slows the runoff by adding idle time, thus reducing runoff that will otherwise overwhelm streets and storm inlets causing flash flooding. These systems are now residential code in some urban areas. Bioretention wells are resource intensive, but very effective.
THIS IS NOT A DRY WELL (Dry wells are much, much smaller capacity and do not have overflow piping).
