Drains to the River
If you happen to be a resident in the Mile High City you may notice a line on your bill for for storm drainage. The storm drainage network in place to control rain and snow run off. This system maintains a safe flow of the water that has had it's natural route altered by development. "Stormwater is generated by water (from storm events or other sources) running across the surface of impervious surfaces, such as streets, sidewalks, parking lots, and roof tops where it picks up contaminants such as oil residue from cars, litter, and debris. Stormwater runs through Denver's storm drain system, where it is naturally treated and the water is reclaimed by the ecosystem."
