Infiltration of rain events is a basic ecological process that has provided our communities with clean reliable water resources since the beginning of human settlement. The practice of stormwater infiltration in the U.S began nearly a century ago. Since the 1930’s monitoring of these practices have documented beyond question it’s contribution to valuable potable ground water supplies to settlements across the country. .

This sequence provides a dynamic check and balance system for regulating velocity and reducing erosion. Correctly sized plunge pools are self regulating and therefore maintain themselves. Pools also improve habitat diversity and serve as refuge for aquatic species during low flow periods. .
