How does grease clog the sewer system?
Grease hardens as it cools when poured down a drain. Even when mixed with hot water, the grease will separate out and settle in plumbing systems and sewer lines. Pouring grease down your kitchen sink costs Charleston Water System thousands of dollars per year in maintenance fees to clean the sewer system. All fats, oils, and the like should be poured into containers for disposal.
