What is a significant consequence of excessive grease buildup in sewage systems?

Excessive grease buildup in sewage systems leads to an increased risk of blockages. Grease can accumulate on the walls of pipes, narrowing the passageway through which wastewater flows. As the buildup continues, it can create significant obstructions, preventing efficient sewage flow. This accumulation often traps other waste materials, exacerbating the blockage and potentially leading to backups in the system. Such blockages can cause overflows, environmental pollution, and costly repairs. Therefore, maintaining proper grease management is essential in sewage systems to ensure smooth operation and to reduce the risks associated with obstructions.
