Greasy foods can be unhealthy for your body, but did you know that fats, oils, and grease (FOG) are bad for your home's plumbing system and the public sanitary sewer system too? In addition to cooking oils and grease, the following are also considered FOG: food scraps, meat fats, lard, shortening, butter/margarine, dairy products, batters, dressings, icing, and sauces. When not disposed of properly, FOG builds up in the sanitary sewer system constricting flow, which can cause costly sewer back-ups into homes and overflow discharges onto streets.

Keep your drains clog-free with the following healthy habits:

  • Can the Grease
    • Pour used cooking grease into an empty soup can or other heat-safe container, and store it in the freezer. Once solidified, toss the can into the garbage.
  • Scrape the Plate
    • Prior to washing, wipe all pots, pans, dishes and cooking utensils with a paper towel to absorb grease.
  • Catch the Scraps
    • Eliminate using the garbage disposal. Use a strainer to catch food scraps in your sink, then toss them into the trash.

Wipes and Personal Items

Disposable does not always mean flushable. Cleaning wipes and baby wipes do not break apart like toilet tissue. They get stuck in sewer pipes and sewer pumping equipment.

Be kind to your plumbing. Put used wipes and sanitary products in the trash. Costs for hiring a plumber to unclog your private sewer line typically range from $75 to $350. These costs do not include the time it takes you to clean up the sewage that may have backed up or the time spent calling and waiting for a plumber.
