4 Types of Subsurface Storm Water Systems That You Should Get to Know
The United States is increasingly becoming an urban society. Despite its many benefits, there are certain downsides to urbanization that severely affect the environment. For instance, vegetation and soil need to be removed, drainage networks need to be built, and land surface needs to be reshaped—all of which contribute to peak discharge, frequency, and volume of floods in nearby streams. Put simply, some of the biggest aspects of urbanization contribute to flooding in many different ways.
Due to the increased risk of flooding, city planners make it a point to include flood protection in their priorities. A variety of technologies are available toward this end, including bioinfiltration, enhanced tree pits, pocket wetlands, green roofs, and subsurface detention, retention, and infiltration practices. Four types of subsurface stormwater systems are briefly described below.
