Stop holiday plumbing clogs by tossing fats, oils and grease into the trash, not down the drain

Post Date:11/21/2019 11:07 AM

The Utilities Department wants to remind residents to “prevent clogs by tossing your FOG.” This means tossing any fats, oils and grease, commonly known as FOG, into the trash, and not down the train. If poured down the sink, FOG can clog sewer lines and cause costly repairs to the homeowner and the City. More than two-thirds of sewer line blockages in Oklahoma City are caused by FOG.

To help prevent clogs, pour liquid FOG into an aluminum can or other lidded container, then place it in the freezer until the FOG becomes solid. You can then toss the container into the trash. The City also recommends throwing all solid food remnants into the trash and using a paper towel to wipe out any remaining FOG from pots and pans before cleaning them in the sink or dishwasher.

“People tend to think that small amounts of oil or grease don’t matter,” said Michelle Aumiller, the City’s environmental unit supervisor. “But even small amounts will build up over time and cause significant problems by clogging household plumbing or the City’s lines. Throwing fats, oils and grease in the trash is an easy way for residents to avoid expensive plumbing visits and help prevent blockages in the City’s wastewater system.”

Aumiller notes that while FOG is a year-round problem, the holidays make a good time to remind people to be careful. “People tend to cook larger meals and use more grease and fat in their holiday cooking,” she said.

Common fats, oils and grease include butter, shortening, margarine, meat trimmings, poultry skin, cheese, milk cream, sour cream, cooking oils, salad dressing, gravy, and mayonnaise.
