Storm Drain Markers Actually Matter

You’ve probably walked past them dozens of times without a second thought—those little metal or plastic signs next to storm drains that say something like, “No Dumping. Drains to River” or “Only Rain in the Drain.” Simple, sure, but these small markers carry a big message.

Let’s talk about why they’re important—and why every town should be using them.

Out of Sight, But Not Out of Impact

A lot of people don’t realize that storm drains aren’t connected to a water treatment plant. Whatever goes down those grates—motor oil, lawn chemicals, pet waste, trash—goes straight into nearby streams, rivers, lakes, or bays. No filtering. No cleaning. Just direct pollution.

Storm drain markers are a way to remind people of that. A small visual nudge can go a long way. Sometimes, all it takes is reading “Drains to Creek” for someone to stop and think, “Wait… so that bucket of dirty mop water I was about to pour in there might actually hurt fish?”

Education Without a Lecture

Let’s face it: most folks don’t read pamphlets or sit through environmental presentations. But a clearly placed marker right by the drain? That gets the point across without the lecture. It’s fast, it’s effective, and it meets people where they’re at—on sidewalks, in parking lots, behind stores.

It’s passive education that works.

A Low-Cost Win for Clean Water

One of the best things about storm drain markers? They're cheap and easy to install. Cities, towns, schools, and even scout troops can take on storm drain marking projects. In a few hours, you can cover a neighborhood and make a real difference in how people treat runoff.

Plus, it shows that your community cares. It's a visible sign that says, “Hey, we value clean water and we’re doing something about it.”

A Little Marker Goes a Long Way

Next time you see a “No Dumping” marker, give it a second glance. It’s doing more than decorating a curb. It’s reminding us all that every storm drain is a direct pipeline to our natural world—and that protecting it starts with small actions.

So if your town isn’t marking storm drains yet… it might be time to start. Because clean water doesn’t happen by accident.
