What is the major cause of stoppages in wastewater lines?

The major cause of stoppages in wastewater lines is primarily due to roots and grease. Over time, grease can accumulate within pipes, creating a sticky buildup that restricts flow and leads to blockages. This is particularly common in residential areas where grease is often washed down drains from kitchens.

Additionally, tree roots can infiltrate sewer lines through small cracks or joints. The roots seek moisture, and once inside the pipe, they can grow and expand, causing significant blockages as they create large masses that obstruct the flow of wastewater.

While foreign objects, corrosion, and inadequate flow can contribute to stoppages, they are not as prevalent or as significant in causing major blockages as the combination of grease accumulation and root infiltration. Therefore, understanding the challenges posed by these two factors is essential in wastewater management and prevention strategies to reduce the occurrence of line stoppages.
