What are some of the things that should not be put down the drain or toilet?

Any products that are labeled as hazardous materials should never be disposed of in the sewer. Hazardous materials are often labeled as corrosive, toxic, reactive or flammable.  The list includes many items we have in our homes such as all-purpose cleaners, antifreeze, paint, paint thinner, pool chemicals, solvents and motor oil to name a few.


Many of the paper products labeled “flushable” should not be disposed of in the sewer.  For example, “disposable wipes” do not breakdown in the sewer and cause clogs in the sewers and pumps.


Animal and vegetable derived cooking oils and grease can block drains and sewer lines.
