A wastewater (sewer) system and a storm drain system are not the same - These two systems are completely different. Water that goes down a sink or toilet in your 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 stream, a creek, a river, a lake, and eventually the ocean. This water may pick up pollutants along the way that are never treated.
There are many types of pollutants that enter storm drains - Some common contaminants include motor oil, pesticides, brake dust, pet wastes, paint, and household chemicals.
The effects of the storm drain pollutants on our water can be harmful - These pollutants can have harmful effects on drinking water supplies, recreational use, and wildlife. Some very popular beaches have even been closed because of contaminated stormwater.
There are ways you can prevent stormwater pollution - By educating yourself on what causes stormwater pollution, you are on the right path to preventing it.
