FOG refers to which substances that can clog sewer pipes?

The correct answer, which identifies FOG, stands for fats, oils, and grease. These substances are commonly found in household wastewater and can accumulate in sewer pipes. When FOG enters the sewer system, it can solidify and merge with other substances, leading to blockages. This accumulation not only causes clogs but can also create backups and overflows, posing significant challenges for wastewater management.

Understanding the components of FOG is crucial for effective collection system maintenance. It highlights the importance of public education on proper disposal methods of fats, oils, and grease, such as through recycling cooking oils or disposing of them in the trash, rather than pouring them down the sink. By managing FOG properly, the efficiency of the sewer system can be maintained, preventing costly repairs and environmental issues associated with overflow incidents.
