Which of the following is a typical cause of sewer blockages?

Grease buildup is a common cause of sewer blockages. Over time, when fats, oils, and greases are disposed of down drains, they can accumulate within the sewer lines. This buildup narrows the pipes, and combined with other waste materials, it can lead to significant clogs. This type of blockage is often exacerbated when hot grease cools and solidifies within the pipes, creating a solid mass that obstructs the flow of wastewater. Understanding the implications of grease buildup is essential for effective wastewater management, as it can lead to overflow, increased maintenance costs, and environmental hazards. Conversely, flushing medications can also contribute to issues in wastewater treatment but does not typically cause physical blockages. Biodegradable products, when properly used, typically break down and do not lead to blockages, while frequent maintenance checks are proactive measures that help prevent such issues from developing in the first place.
