The majority of the general public does not realize that the storm drain system is a separate system from the wastewater system that handles household by-products. Unlike the wastewater system, storm drains carry everything that enters them to the nearest water source.
Anything put into the drain will end up in a nearby water body. Furthermore, city ordinances restrict any person from intentionally placing items into storm drains. Storm drain markers help increase this awareness, and combat this problem.
