Infiltration practices are designs that enhance water percolation through the soil and remove pollutants in the process. A ‘Rain Garden’ is a common residential design, and an aesthetically appealing project! As snow melts, it’s runoff accumulates in these depressed/trenched areas. Captured water generally leaves to the neighboring soils within 48 hours. Directing water from roof downspouts or paved areas enable the removal of pollutants prior to discharge into receiving waters. For more information visit the Water Environment and Reuse Foundation.
