The Connection Between FOG (Fats, Oils, Grease) and Sewage Clogs

Fats, oils, and grease (commonly referred to as FOG) are byproducts of cooking and food preparation that pose a significant threat to sewage systems. When improperly disposed of, these substances solidify within sewer lines, leading to blockages and costly maintenance issues. FOG-related clogs are a widespread problem for both residential and municipal sewage systems, affecting water flow, treatment efficiency, and the environment.

This article explores how FOG contributes to sewage clogs, the consequences of improper disposal, and effective strategies for managing and preventing FOG buildup.

How FOG Enters Sewage Systems

FOG primarily originates from kitchens and food service establishments, where it is generated during cooking, frying, and dishwashing. Common sources of FOG include:

  • Cooking oils and grease
  • Butter and margarine
  • Animal fats
  • Sauces and dressings
  • Dairy products
  • Residues from washing greasy pots, pans, and dishes

Improper disposal, such as pouring grease down the drain or into the garbage disposal, allows FOG to enter the sewage system. Even small amounts of grease can accumulate over time, forming significant blockages.

The Formation of FOG-Related Blockages

Once FOG enters the sewer system, it begins to cool and solidify. This process creates a sticky residue that adheres to the walls of sewer pipes. Over time, additional FOG, food particles, and debris accumulate on the residue, leading to the formation of clogs.

Factors That Exacerbate FOG Buildup



  1. Cold Temperatures: Cooler water temperatures accelerate the solidification of fats and grease, increasing the likelihood of clogs.
  2. Pipe Material: Rough or aging pipes provide more surface area for FOG to adhere to, worsening buildup.
  3. Improper Maintenance: Infrequent cleaning or maintenance of sewer lines allows FOG to accumulate unchecked.

Preventing FOG Clogs

Effective prevention strategies focus on minimizing the entry of FOG into sewage systems and promoting proper disposal practices.

Best Practices for Residential Properties

  • Avoid Pouring Grease Down the Drain: Instead, collect grease in a heat-safe container and dispose of it in the trash once it solidifies.
  • Use Strainers: Place sink strainers over drains to catch food particles and prevent them from entering the plumbing system.
  • Wipe Greasy Dishes: Use paper towels to wipe excess grease from pots, pans, and dishes before washing them.

Best Practices for Food Service Establishments

Municipal Initiatives

  • Public Education Campaigns: Municipalities can raise awareness about the impact of FOG on sewage systems and encourage proper disposal practices.
  • Fines for Violations: Implementing penalties for improper FOG disposal can discourage harmful practices and promote compliance.
  • Advanced Monitoring: Use smart sensors to detect FOG accumulation in sewer lines and address potential clogs proactively.
