Say no to FOG to Avoid a Clog This Holiday Season

Published Nov 22, 2021

As the holiday season is set to begin, the kitchen tends to be a busy place. Whether you plan to have a house full or just turkey for two, it is important to be kind to your drain and avoid mishaps that could have you plunging or dealing with a sewer backup – activities that no one wants to partake in, especially during the holidays.

As you prepare your family feast and during the extensive clean-up that follows, no amount of grease should ever go down your drain. This includes the cooking oil that may be used to deep-fry the turkey and any food remnants containing Fat, Oil, or Grease (known as FOG), including gravy, buttery potatoes, or baked goods like leftover pumpkin pie. FOG can cause sewer damage and backups.

When water goes down the kitchen drain, it does not simply disappear. It travels through the sewer system to the wastewater treatment plant, where it is processed and cleaned. That water is then reused for groundwater recharge and landscape irrigation or released into nature to join the water cycle once again. Because the sewers get water from thousands of kitchens, the smallest amount of grease and oil can build up and entirely clog a pipe as the fats and grease cling to the inside your city's sewer pipes causing unnecessary damage. Those greasy contaminants can also make wastewater treatment and processing far more challenging than it has to be.

To avoid clogs, back-ups and ensure your neighborhood keeps things moving, here are a few ways to keep your plumbing working throughout the holidays and save your city time and money while maintaining FOG at bay:

  • Pour cooking oils and grease into a small container with absorbent material, such as a paper towel or coffee grounds, and dispose of it in the trash or recycle it at a grease disposal or environmental recycling site that may be available in your city.
  • Scrape food from dishes into the trash (not the garbage disposal) and wipe down greasy plates, pots and pans with a paper towel before washing.
  • Filter and reuse large amounts of deep-frying oil.
  • Refrigerate and reuse fat for cooking.
  • Prevent food from entering your sewer by covering your kitchen sink drain with a strainer.
  • Limit your use of garbage disposals because they only shred solids and do not prevent grease from building up again.
  • And remember that hot water from your tap or dishwasher might appear to melt the grease and push it further down the drain, but it will solidify again once it cools. This will cause a build-up in the main sewer system ad can affect neighboring sewer lines.

In addition to time spent in the kitchen, we know that with a house full of company, the bathroom can also see an increase in traffic flow, so it's important to ensure your guests are sewer savvy by letting them know that what you flush matters . It's important to remind them that the toilet is not a trash can. They should never flush wipes, paper towels, facial tissue, diapers, feminine hygiene products, cotton swabs, cotton balls, band-aids, or dental floss. These items do not break down in the same fashion as toilet paper, so they cause clogs and get tangled with everything else, fighting to get through the pipes, causing back-ups. So make sure they understand that human waste and toilet paper are the only acceptable items to be flushed.

By not putting any unneeded strain on all your drains and pipes, you can avoid an unplanned visit from your plumber, not just during the holidays but year-round. Clogged pipes and sewer back-ups are never a good surprise, plus they can do significant damage to your home, neighborhood, and the environment. Limiting contaminants and unwanted items from entering our pipes ensures a clean and properly functioning sewer system, which benefits us all.
