Activities like walking your dog or driving your car can leave pollutants on the ground that can be washed off in rain water. All the hard surfaces you use every day, such as parking lots, driveways, rooftops, and sidewalks, dramatically increase the rate and amount of runoff. What each of us can do to reduce pollutants in storm water runoff might seem small, but it can all add up to reducing the problems caused by storm water. Here are some ways you can help:
Reduce the Rate and Volume of Runoff
- Have roof runoff to the lawn instead of driveway, sidewalk, or the street
- Use rain barrels at your downspout and recycle for irrigation
- Aerate lawn
- Maintain a healthy lawn
All Sources of Runoff
- Consider building rain gardens to capture runoff from roofs, lawns, and driveways
Q. What is a rain garden?
A. A shallow depression that is planted with deep-rooted native plants and grasses. It is positioned near a runoff source like a downspout or driveway to prevent rainwater runoff from reaching the sewer system.
Reduce Pollutants in Storm Water Runoff
- Dispose of fluids properly
- Reduce a few trips with your car each week by walking, biking, or riding the bus
- Do not blow grass clippings onto street, sidewalk or driveway
- Buy phosphorus free fertilizers
