Stormwater is made of rainwater and snowmelt. It flows into the storm drainage systems, which in turn flows into our creeks, streams and rivers. Because stormwater isn’t treated before it flows into rivers and streams, it’s important to keep it as free of pollutants as possible.
Clean up after your Pet:
* Pick It Up
* Bag It Up
* Throw It Out
Help Keep Stormwater Clean
Many of us think of industries dumping chemicals as the source of water pollution, but the truth is our water can also be harmed by things we do every day. Think about this…when it rains, water washes over lawns, sidewalks, streets, construction sites, industrial sites and more. This water picks up litter, lawn fertilizer chemicals, bacteria from pet waste, automobile oil and more. This polluted water then enters streets, gutters and the storm drains before flowing into the closest lake or stream.
- Pet waste
- Motor oil/antifreeze
- Grass clippings/yard waste
- Too many nutrients

Dumping into a Storm Drain is a Crime
Dumping liquid or solid waste into a storm drain or creek is a crime.
If you see illegal dumping or a spill, report it to Northglenn’s Neighborhood Services Division at 303.280.7876.
Stormwater runoff during “land disturbing” activities such as construction can have a significant impact on water quality. As stormwater flows over a construction site it can pick up pollutants like sediment, construction debris, and chemicals such as gas, fertilizer, and paint. Polluted stormwater runoff can harm or kill fish and other wildlife. Sedimentation can destroy aquatic habitat and high volumes of runoff can cause stream bank erosion.
