Often people think that disposing of waste liquids, products, etc. down a drain is ideal because eventually it all gets cleaned out at a wastewater treatment plant. After all, all drains go to the same place right? The answer to that question however is NO.
 
It is important to understand the difference between sanitary sewers and storm sewers so we can protect our water resources.  The sanitary sewer is a system of subsurface pipes that carries sewage from bathrooms, sinks, kitchens, and other plumbing components to a wastewater treatment plant where it is filtered and treated before being discharged. 
 
The storm sewer however is a system designed to carry rainfall runoff and other drainage. It is not designed to carry sewage or hazardous wastes that can enter the environment as pollution. The runoff is carried in subsurface pipes and/or open ditches and discharges untreated into local streams, rivers and other surface water bodies. Storm drain inlets are typically found in curbs and low-lying outdoor areas. Some older buildings have basement floor drains that connect to the storm sewer system. (MSU WATER)
 
Disposal of chemicals or hazardous substances to the storm sewer system damages the environment. Motor oil, cleaners, paints and other common household items that get into storm drains can poison fish, birds, and other wildlife, and can find their way into drinking water supplies. In addition, grass clippings, leaves, litter, and organic matter can clog storm drains, cause flooding, and increase nutrient pollution in waterways.  You may have seen storm drain tags placed by Warren County SWCD reminding people "Only Rain Down the Drain" and other similar messaging to help protect our environment and water resources.

There are a wide range of things people can do at home to help safeguard our water sources; from installation of rain gardens and rain barrels to slow down stormwater runoff to washing your car NOT in the impervious driveway.  But simply put, only rain water should enter our storm drains!

It's spring, so we are getting lots of rain lately.  Rain always disrupts the land a bit and causes concern as it flows through yards, ditches and construction sites.  But where does it all go?  If you were paying attention in your second grade science class you learned about the water cycle.  Some of the water soaks into the ground and recharges our groundwater.  Smaller amounts of water evaporate to be collected in the sky creating more rain.  But most of our rain water eventually makes its way to streams and rivers, oceans and lakes.

Our storm sewer systems do the job of collecting and conveying the rain water to its destination.  These storm sewer systems collect the quickly accumulating rain and convey it down stream to make roads and bridges safe and to protect other property features such as houses, buildings and airports.  There is a common misconception that the catch basins and yard inlets actually flow to a treatment facility.  Some people think the water is taken to the same location that our sanitary sewers take and treat our sewage.  This is not true.  The catch basins and yard inlets you see around town flow directly to ponds, lakes, rivers and oceans.
