Protecting Storm Drains and Inlets From Sediment and Pollutants

The trouble with stormwater runoff is that it travels along the ground surface and over pavement, picking up sediment and other contaminants as it goes. A well-designed surface water runoff collection and drainage system will funnel runoff from relatively large areas into individual collection points such as inlets and drains
