How does grease clog the sewer system?
Grease hardens as it cools. Even when mixed with hot water, the grease will separate out and settle in plumbing systems and sewer lines. Over time, grease accumulation can severely reduce the capacity of a pipe or block it completely, sometimes resulting in sewer back-ups or overflows.

Dispose of fats, oils, and grease by pouring it into a container and putting it in the trash.
