Why Should We Follow “Only Rain Down the Drain?”

As Wisconsin residents, we are responsible for protecting the water resources that make our state beautiful. By following the principles of "Only Rain Down the Drain," we can ensure that stormwater runoff remains free from harmful pollutants. When substances other than rain and snowmelt enter storm drains, in most communities around Wisconsin, these substances are carried directly into streams, rivers, and lakes without undergoing any treatment. These substances can include harmful chemicals, oil and grease, pesticides, fertilizers, and other pollutants. The presence of such pollutants in our waterways can degrade water quality, harm aquatic life, and disrupt delicate ecosystems.

Several types of pollutants can enter our waterways through stormwater runoff if not properly managed. Household chemicals, such as cleaning agents, paints, solvents, and pesticides, can be washed into storm drains and contribute to water pollution. Automotive fluids, including motor oil, antifreeze, and brake fluid, are another common source of pollutants. Yard waste, such as grass clippings, leaves, and branches, can also find their way into storm drains and add excess nutrients to water bodies, leading to harmful algal blooms. Understanding the various pollutants that can enter our waterways through stormwater runoff is vital in taking proactive measures to prevent pollution and protect water quality.

Whether it's properly disposing of household chemicals, managing pet waste responsibly, washing your car properly, or preventing and cleaning up spills, each action we take around our property contributes to cleaner and healthier waterways.

How Can You Help Ensure “Only Rain Down the Drain?”

Start by familiarizing yourself with local stormwater regulations and guidelines. Different communities may have specific requirements regarding drain disposal and stormwater runoff prevention. By staying informed and understanding the regulations, you can ensure compliance and take the necessary steps to prevent pollution. Contact your local government or stormwater management agency to access information on regulations and guidelines applicable to your area.

Follow these other tips and best practices to prevent harmful substances from ending up in our storm drains and waterways.

1. Properly dispose of household chemicals and hazardous materials: Household chemicals and hazardous materials should never be disposed of or dumped into storm drains. These substances can harm water quality and pose risks to human health and the environment. Instead, follow proper disposal methods outlined by your local waste management authority. Many communities have designated collection days or drop-off centers for safe disposal of hazardous materials. By responsibly handling and disposing of these substances, you can prevent their entry into the stormwater system and protect our water resources.

2. Keep yard waste and debris out of storm drains: During yard maintenance activities, it is crucial to prevent yard waste and debris from entering storm drains. Sweep up grass clippings, leaves, and other yard waste and dispose of them properly in yard waste bags or compost bins. Avoid blowing or raking yard waste into streets, gutters, or storm drains, as they can quickly be carried away by stormwater runoff. By keeping yard waste out of the storm drain system, you help prevent clogging, reduce the risk of localized flooding, and contribute to cleaner waterways.

3. Prevent oil and other vehicle fluids from entering the stormwater system: Proper vehicle maintenance is essential not only for the longevity of your car but also for protecting our waterways. When performing maintenance tasks such as oil changes or fluid top-ups, it's crucial to prevent vehicle fluids from entering the stormwater system. Place a drip pan or absorbent material under your vehicle to catch any spills or leaks. If any fluids do spill, clean them up promptly using absorbent materials like kitty litter or oil-absorbent pads. Regularly checking your vehicle for leaks can also help prevent oil or other vehicle fluids from ending up on driveways or streets where stormwater runoff can get contaminated. By taking these simple precautions, you can prevent harmful substances like oil, coolant, and brake fluid from contaminating storm drains and polluting our water resources.

4. Properly dispose of used motor oil and other vehicle fluids: When it comes to disposing of used motor oil and other vehicle fluids, it is essential to follow proper procedures. Never pour these substances down the drain or onto the ground, as they can contaminate groundwater and surface water. Many automotive stores, service stations, and recycling centers accept used motor oil and other fluids for proper disposal. Collect used motor oil in a clean, leak-proof container and take it to a recycling facility or an authorized drop-off location. By responsibly managing vehicle fluids, you can prevent pollution and ensure the protection of our waterways.

5. Properly dispose of pet waste to prevent contamination: Pet waste may seem harmless, but it can pose significant risks to water quality. When left on the ground, pet waste contains harmful bacteria and parasites that can be washed into storm drains during rainfall. These contaminants can then find their way into our water bodies, posing health risks to humans and aquatic life. To prevent pet waste pollution, always pick up after your furry friends and dispose of their waste properly. Use a plastic bag or pooper-scooper to collect the waste and place it in a designated pet waste disposal bin. Some communities provide specific pet waste stations in parks and public areas for convenient disposal. By being responsible pet owners and properly managing pet waste, we can minimize the risk of contamination and protect the water quality of our communities.

6. Take preventive measures to avoid spills: Preventing spills is crucial in minimizing the risk of pollutants entering the stormwater system. When handling hazardous substances or materials, take preventive measures to avoid accidental spills. Store chemicals, fuels, and other potentially hazardous materials in secure containers and ensure they are properly sealed. Use spill containment systems, such as trays or secondary containers, to prevent spills from spreading if accidents occur. By implementing preventive measures, you can significantly reduce the chances of spills and protect our waterways.

7. Use a Commercial Car Wash OR Wash Your Vehicle on Permeable Surfaces Like Grass: Car washing is a common activity that can have unintended consequences for stormwater pollution if not done responsibly. When cars are washed on driveways or other impervious surfaces, the runoff containing soap, detergents, oils, and other pollutants flows directly into storm drains and eventually can enter our waterways. These pollutants can degrade water quality, harm aquatic life, and disrupt the delicate balance of ecosystems. To reduce the impact of car washing on stormwater pollution, it is recommended to avoid washing your vehicle on your driveway or other impervious surfaces. Instead, consider using commercial car washes designed to capture and treat the runoff, preventing pollutants from entering the stormwater system. If you prefer washing your vehicle at home, choose a location with a permeable surface such as a grassy area or gravel driveway. This allows the runoff to be filtered naturally through the soil, removing pollutants before reaching water bodies. By washing your car on permeable surfaces, you can help reduce the amount of pollutants that enter the stormwater system and contribute to cleaner waterways.
