Grease Disposal 
Where Grease Comes From
Grease usually comes from these sources:
  • Meat fats
  • Lard
  • Cooking Oil
  • Shortening
  • Butter
  • Margarine
  • Food Scraps
  • Sauces
  • Deep Frying
How Grease Destroys Pipes
Grease and oils clog pipes: Grease enters the sewer system through household drains. It sticks to the insides of the sewer pipes on your property and in the street. Over time, it builds up and blocks the pipes completely, causing a sewer backup.

What Grease Can Cost You
Grease-clogged pipes lead to these costly problems:

  • Raw sewage overflowing into your homes, yards, streets, and parks means an expensive and unpleasant cleanup that the homeowner is responsible for paying for. 
  • Potential contact with disease-causing organisms due to improper cleanup. 
  • Damage to home interiors.
  • Higher sewer bills due to increased maintenance costs for the PMUA, from repeated cleaning of sewers in streets.
How to Dispose of Grease
Keep grease out of your drains:

  • Pour grease and scraps into a cup, can, or small container (preferably with a lid) and throw in the GARBAGE.
  • You can also freeze it (less mess).
  • Wipe out greasy pots/pans with a paper towel before washing them, and throw the paper towel in the GARBAGE.
