What's the Difference Between Sanitary and Storm Sewers

You've seen one drain, you've seen them all, right?  Not so!  It's  important to understand the difference between sanitary sewers and storm sewers so we can prevent environmental damage.  

The sanitary sewer is a system of underground pipes that carries sewage from bathrooms, sinks, kitchens and other plumbing components to a wastewater treatment plant where it is filtered, treated and discharged.  

The storm sewer is a system designed to carry rainfall runoff and other surface water drainage.  It is not designed to carry sewage or accept hazardous wastes.  The runoff is carried in underground pipes or open ditches and discharges, untreated, into local streams, rivers and other water bodies.

Tips to keep our environment clean:

              Do not pour anything into the storm sewers,  take paint, solvents, cleaners and other hazardous wastes to the                          Eaton County recycling events:  May 1, 2021


              Keep storm sewers drains clear of leaves, grass clippings, sticks and litter


              Repair any leaks and drips from your vehicle


              Collect and recycle motor oil


              Clean up spills and don't wash them into a drain 

Thank you for keeping our waters safe and clean!
