What are the consequences of sewer pipes being clogged by FOG?

When sewer pipes become clogged by fats, oils, and grease (FOG), one of the primary consequences is the overflow of the system, which can lead to the release of untreated wastewater. This situation poses a significant public health risk, as untreated wastewater can contaminate water bodies, harm aquatic life, and cause sanitation issues in the surrounding areas. The clogging can disrupt the normal flow within the sewer system, generating backpressure that may lead to overflows at manholes or other system components, spilling untreated sewage onto streets or into local waterways. Addressing FOG buildup is crucial for maintaining the integrity and functionality of sewer systems, preventing both environmental damage and public health hazards.

Other consequences, such as urban flooding, can occur due to a lack of proper drainage, but the direct and immediate issue resulting from FOG clogs is the overflow and subsequent release of untreated wastewater. Improved wastewater treatment and increased capacity are not outcomes associated with FOG accumulation; rather, they are desirable conditions that cannot be achieved when the sewer system is compromised by blockages.
