Getting rainfall into the ground is important for cleaning up the impurities that are collected as the rainfall runs off the ground surface on its way to the storm drains in the street or on its way to rivers and wetlands. Infiltration or recharge of the stormwater into the ground helps to clean the runoff of impurities collected as the runoff travel over the surface. All new developments are required to recharge some of the runoff to help clean the impurities out of stormwater runoff.
VEGETATIVE GROUND COVER:
Impervious surfaces such as paved roads, parking lots and buildings don't do anything to clean the rainwater and actually contributes to the impurities found in the typical stormwater runoff. Keeping the ground surface covered with vegetation prevents the rainfall runoff from quickly eroding the soil and picking up sediments. Vegetation on the ground surface is one way to stop this type of runoff pollution .
