What is Stormwater Run-off?
Stormwater run-off is precipitation that falls to the ground and comes in contact with soils, greases, debris, and other contaminants from areas such as roadways, parking lots, and rooftops. Stormwater run-off is one of the leading causes of water quality problems. Stormwater carries debris and pollutants directly into our water sources, which can also endanger the lives of humans, animals, and plant life. Managing stormwater run-off helps eliminate and/or reduce these negative impacts.
Mandated by Congress under the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) Stormwater Program is a comprehensive two-phased national program for addressing the non-agricultural sources of stormwater discharges which adversely affect the quality of our nation's waters. The program uses the NPDES permitting mechanism to require the implementation of controls designed to prevent harmful pollutants from being washed by stormwater runoff into local water bodies.

The Drain is only for Rain! - Read for full details
- A sewer system and a storm drain system are not the same. These two systems are completely different. The water that goes down a sink or toilet in you home or business flows to a wastewater treatment plant where it is treated and filtered. Water that flows down driveways and streets and into a gutter goes into a storm drain which flows directly to a lake, river or the ocean. This water may pick up pollutants along the way which are never treated.
- Less than 2% of the water on the earth can actually be consumed by human beings.
- Storm drains do not remove pollutants and were designed for the specific purpose of draining water from sidewalks and streets.
- Anything you place in storm drains goes directly into a lake or stream.
- One of the most common pollutants found in storm drains and creeks is detergent from the washing of cars.
- It is illegal to dump wastewater or water containing soaps, cleaning, products, or grease and oil into streets or storm drains
- The improper use of lawn fertilizers can be a main source of water pollution.
- Landscaping can help reduce storm water runoff.
- Trees and shrubs require less fertilizer than other plants, helping to further reduce the chance of pollution.
- Most water pollution is preventable.
