storm_water_descriptionWhat is Stormwater?

Stormwater is the runoff from storm events or spring melt. Stormwater runoff needs to be treated because it carries litter, oil, gasoline, fertilizers, pesticides, pet wastes, sediments, and anything else that can float, dissolve, or be swept along by the moving water. Left untreated, polluted stormwater can reach nearby waterways where it can harm and even kill aquatic life. It can also pollute groundwater so always sweep up litter and debris from walkways and sidewalks, driveways, patios and especially around storm drains.

What Can You Do To Help?

As stormy weather approaches, here are some other items you can do at home.

Auto Care

Oils, grease,and cleaning fluids can kill aquatic life. You can prevent these contaminants from polluting ground water by:

  • Washing cars on lawn or gravel surfaces with an environmentally friendly cleaner, or by using a commercial car wash that collects, treats and recycles its waste water.
  • Use drip pans to collect auto fluids and fix leaks promptly.
  • Clean up spills with dry absorbent materials. Kitty litter is excellent for this.
  • Dispose of oil and grease properly.

Pet Waste

Pet waste is a major source of bacteria that can result in transmission of infections and diseases. Don’t leave pet waste on the ground. Scoop it, bag it, and dispose of it properly.

Yard Care

Fertilizer promotes algae growth that can kill fish and wildlife, and contaminate ground water.

  • Use fertilizers and pesticides only if you have to. When you do, try and use sparingly. Where possible, try and use a bio-friendly natural compost instead.
  • Keep chemicals off paved surfaces and sweep up spills.
  • Mow laws to the appropriate height to reduce the need for fertilizers.
  • Improve your soil and conserve water by using composts and mulch.


Help rain water soak into the ground by directing roof and driveway runoff  towards grassed areas or areas with plantings. This will slow surface runoff where rainfall ends up immediately in storm drains. Instead, water will have more time to filter down into the local water table.




Remember to keep everything out of the stormwater systems except the rain water they are designed to collect.
