Municipal wastewater sewer systems and treatment plants are designed to transport and treat household sewage (wastewater + organic solids). Unfortunately, our society become accustomed to flushing many other waste products down the drain which end up creating problems in the public sewer system. You can help limit these problems by learning what NOT to flush.
For more information on these contaminants, including proper disposal, please visit the What Not to Flush page.
Whether you flush it down the toilet, wash it down the sink, or mop it down the floor drain, it all leads to the same public sewer system. Visit the "How the Sewer Works" page for more information.
