Why Does It Matter What I Put Down My Sewer Drain?

Any solid matter that you put down the toilet or drainpipe has the potential to cause blockages in both the public sewer and your private service. This can lead to:

  • Raw sewage overflowing in your home or your neighbor's home;
  • An expensive and unpleasant cleanup;
  • Raw sewage overflowing into yards, and streets;
  • Potential contact with disease-causing organisms; and
  • An increase in operation and maintenance costs for local sewer departments.

Private services (the part of the network between your home and the public sewer) use narrow pipe-work and sometimes have bends in them where solid objects can lodge and cause blockages. It is the responsibility of the homeowner to maintain private drainage systems.

What NOT to put down the toilet, drain or garbage disposal

FATS, OILS AND GREASE are probably the biggest problem in our sewer systems today!  These substances solidify and affix themselves to the main.  These “fat blobs” then attract and collect other substances which just add to the size of the blobs, creating blockages and restrictions.  Other items that should not be placed in your drains include:

  • coffee grinds
  • egg shells
  • produce stickers
  • chunks of garbage
  • disposable diapers
  • disposable wipes
  • feminine hygiene products
  • paper towels
  • "flushable" cat litter
  • rags
  • condoms
  • motor oil, transmission fluids, anti-freeze or other toxic chemicals
  • solvents, paints, turpentine, nail polish, polish remover

  • flammable or explosive substances
  • corrosive substances that are either acidic or caustic
  • needles and sharps
  • prescription and over-the-counter medications

The above is just an example of items that should not enter the sewer system.  These are damaging to both private lines and public lines and cause major problems for everyone.
