What is one effect of grease buildup in collection systems?

Grease buildup in collection systems can significantly reduce the effective diameter of pipes. As grease accumulates on the inner walls of the pipes, it leads to a narrowing of the passage available for wastewater flow. This reduction in diameter fosters an increased likelihood of blockages, as the grease can coalesce with other materials such as hair and debris, forming clogs. The risk of blockages not only disrupts the normal operation of the sewer system but can also result in sewer overflows, which pose environmental and public health risks. Thus, understanding the effects of grease buildup is crucial for maintaining a functional and efficient collection system.
