Stormwater 101

Below you will find information that is specific to residents, businesses, and construction. While these groups engage in different activities, they all have the potential to impact stormwater.

What is Stormwater Pollution?

Stormwater pollution occurs when rain or snowmelt runs off of our roofs, streets, and curb and gutter directly into the storm drainage system, picking up pollutants as it goes. These pollutants include things like trash, oil, and dirt. The storm sewer system is different than the sanitary sewer system. The storm sewer system carries water directly to our waterways without being treated. The sanitary sewer system goes to a water treatment plant prior to discharging into our waterways. Most of the time activities that we perform outdoors will drain into the storm system without being treated and the water from our homes will go directly to the sanitary sewer.

Why Is This Important?

The pollutants that are washed into our streams, lakes, rivers, and reservoirs impact aquatic plants and animals. These organisms need clean water to survive and thrive. Excess nutrients from sources like pet waste, yard waste, and fertilizers cause excess algae growth. Overabundant algae are not only unattractive, but they can also impact our health, as well as the health of our children, pets, and aquatic life. Bacteria, other pathogens, and chemicals are also dangerous to our health and the health of aquatic life.

Many of us like to recreate in the water. Swimming, fishing, and just splashing around, but poor water quality means we can’t safely enjoy these beautiful resources. What’s more, it can impact water quality. When polluted water is pulled from our reservoirs it is more expensive to treat and not all pollutants are easily removed.

How Can I Help?

You can help by making sure the pollutants from your everyday activities don’t end up in our stormwater! By picking up pet waste, yard waste, and trash you are protecting water quality. See the below links for more ways to help!
