The majority of sewer backups and overflows caused by fats, oils, and grease (FOG) originate in residential areas. You can help prevent clogs by learning about FOG and how to dispose of it. Some common sources of FOG include:
Fatty food scraps
Creamy or oily sauces
Milk and other dairy products
Butter or margarine
By following three simple steps, you can make sure your pipes keep flowing properly:
Just as fat accumulates and causes blockages in human arteries, oil and grease solidifies and accumulates in household pipes, restricting the flow of wastewater and causing sewer backups and overflows.
How it starts: Fats, oils, and grease (FOG) separates from other liquids as it goes down your drain. The FOG cools and sticks to household pipes and sewer pipes.
A matter of time: Over time, pipes become clogged and sewage flow becomes restricted.
Nowhere to go but back: The clogged pipe eventually backs up and floods your home with wastewater. Or it causes it to overflow onto the street.
Yes! FOG is responsible for more than half of SASD’s sewer problems. When poured down the drain, FOG clogs the sewer system and causes backups or overflows. The result:
Increased customer rates
Health and environmental hazards
Increased maintenance for cleaning messes and replacing sewer pipes
How does FOG create a sewer blockage?
When poured down the drain, FOG cools, solidifies, and floats to the top of other liquids in sewer pipes. The FOG layer sticks to the sewer pipes and, over time, restricts wastewater flow. It can then cause a sewer backup or overflow.
