Why should kitchen grease be avoided in a septic system?

Kitchen grease should be avoided in a septic system because it can solidify and block pipes, leading to clogs and system failure. When grease enters the septic system, particularly if it cools down, it can congeal and form large masses that adhere to the walls of the pipes. This buildup restricts flow and can cause obstructions, which may result in backups and require costly repairs. Over time, the accumulation of grease can also hinder the function of the drain field, as it interferes with the natural absorption of wastewater, ultimately impacting the entire septic system's performance. Proper disposal of kitchen grease is crucial to maintain a healthy and functional septic system.
