Storm Water
Simply put, stormwater is rainfall that does not soak into the ground but instead flows over the land or in the Stormwater Sewer System to the nearest body of water, which in our case is the I&M Canal. In urban areas such as Lemont, much of the land is covered by impervious surfaces such as streets, buildings, parking lots and driveways which is why a Storm Sewer System is necessary. This water is not treated so it is important not to dump any chemicals, drain RV sewer waste or throw garbage into the street where they can wind up in the sewers and pollute our waterways.
