Storm drains are designed to move rain off streets, not waste. Anything poured or thrown into them flows directly into our local rivers and streams. That’s why it is important to remember: only rain goes down the drain. Dumping anything else, such as household products, soapy water, yard waste, and litter, means dumping straight into streams.
Where Do Storm Drains Go?
Part of the confusion about storm drains comes from not knowing where they lead. Storm drains are part of the stormwater sewer system infrastructure. This is typically a completely different system than the wastewater (or sanitary) system that connects to our homes and businesses.
The wastewater system carries water from sinks, toilets, tubs, and showers to a treatment plant, where the water is cleaned before being discharged into waterways. Storm drains, on the other hand, do not lead to a treatment plant. Storm drains are actually a direct connection to local rivers and streams. They discharge stormwater from the street or parking lot directly into nearby rivers, streams, or ponds. Anything that goes in a storm drain is not treated before it enters our waterways.
The Impact of Dumping
Because storm drains are connected to rivers and streams, they should never be used to dispose of waste. The following items should never be dumped or poured into storm drains:
- Household chemicals from cleaning supplies to lawncare products
- Automotive fluids
- Paint
- Soapy water from car washing and outdoor cleaning
- Yard waste such as grass clippings and leaves
- Pet waste
- Litter and trash
If these chemicals and waste are put into storm drains, they enter waterways immediately. These pollutants degrade water quality and can be toxic to fish, aquatic insects, and other wildlife. Poor water quality also affects people, reducing opportunities to safely fish, paddle, and enjoy a clean, healthy ecosystem.
Dispose of Waste Properly to Protect Rivers
Protecting rivers is simple: only rain goes down the drain. For everything else, dispose of these materials safely and properly to protect the environment. Many household chemicals and automotive fluids can be taken to a Household Hazardous Waste (HHW) facility, such as Naperville’s HHW location. Recycle paint at PaintCare drop-off sites throughout Illinois. When washing your car at home, direct soapy water into grass or hardy landscaping, not into the street or storm drain. Participate in your community’s yard waste and leaf collection program or learn to compost them at home. Whether at home or out in public, be responsible for your pet and any litter that could end up in our waterways.
Be a Storm Drain Steward
Storm drains are an important part of our stormwater system, moving rain off streets and into nearby rivers and streams. Whatever enters storm drains is not treated first, which is why only rain should go down the drain.
You can go a step further by being a “storm drain steward,” taking a moment to clear leaves, litter, and other blockages from drains near your home. By being mindful of storm drains, we can help them work properly to prevent flooding while also protecting clean water in local rivers and streams.
