What is the maximum temperature allowed to enter the sanitary sewer?

The maximum temperature allowed to enter the sanitary sewer is established to prevent damage to sewer systems as well as to protect public health and safety. The correct answer is 150°F, which reflects the threshold at which wastewater can be discharged without causing harm to the sewer infrastructure or treatment facilities.

At temperatures above this limit, there is a risk of damaging the pipes, creating a hazardous environment for personnel, and potentially affecting biological treatment processes at sewage treatment plants. Therefore, the regulations set this maximum temperature to ensure that the integrity of the sewer system is maintained and that treatment processes can operate effectively without adverse effects caused by high-temperature discharges.

The other options, while they may seem feasible, do not align with the standards set forth in plumbing codes regarding safe discharge temperatures, highlighting the importance of adhering to the established maximum to protect both the infrastructure and the environment.
