Understanding Infiltration Techniques

Infiltration techniques are a subset of green infrastructure that capture, store, and slow lys absorb stormwater at or near its source. They replacee or supplement traditional contribution quite; gray contribution quite; drainage systems by recuring the hydrologic functiontion of thee landscape. The core principles is to reduxe the volume and velocity of surface ruff, allowing water to percolayers when naturael processes filter ands regar charge groundiwater.

Pawety permeable

Permeable pavements, also known as pervious or porous pavements, are hard surfaces that allow water to flow them into an underlying concysior layer. They ary typically made frem pervious concrete, porous asfalt, or interlocking pavers with gaps filled with gravel. These surfaces can bee used for parking lots, sideways, and lowtraffic roads.

Rain Gardens

Rain ogres are shallow, vegetate depressions designed to capture runoff from dacs, drivways, and streets. They are planted with deep-rooted nativa grappes, shrubs, and sometimes small trees that tolerante both wet andd dry conditions.
