Stormwater 101

In many parts of Pennsylvania, stormwater overwhelms aging sewage infrastructure, causes flood damage, and puts people’s health at serious risk.

Stormwater 101

Unfortunately, the problems associated with stormwater aren‘t limited to major storms; they often result from the average rainfall event. Human activities have altered the landscape so dramatically that the natural system for stormwater management no longer works.

Consider the path rainfall takes when it hits the ground: it either soaks into the ground to become groundwater, evaporates, or flows over the surface of the land. This overland runoff—stormwater—feeds our surface waters, but it also carries sediments, chemicals, automobile oil, trash, and other natural and not so natural debris along with it. Groundcover, trees, soil, wetlands, and a wide range of other landscape features act as buffers and barriers that slow stormwater, trap or filter out pollutants, and enable infiltration and evaporation to occur.
