How Marking Drains makes a difference

Environmental experts have indicated that much of the pollution in our waterways is from stormwater runoff, which contains urban and agricultural pollutants. Curbside storm drains can be a channel for pollution. That means that putting trash or chemical-ridden liquids, such as motor oil or paint into the storm drains is equivalent to throwing it right into the bays, creeks and river. 

After heavy rains, storm water runs off our streets and parking lots into storm drains, picking up leaves, debris and litter along the way. These substances clog the pipes causing streets to flood. Storm water also collects excess pesticides, fertilizers, pet waste and other substances. These can be harmful to aquatic life and residents who recreate in local waters.
