What is the maximum temperature allowed into a POTW under Massachusetts regulations?

The maximum temperature allowed into a Publicly Owned Treatment Works (POTW) under Massachusetts regulations is 40°C or 104°F. This regulation is established to protect the treatment process and the microorganisms that are essential for breaking down waste.

At higher temperatures, the activity of these microorganisms can be adversely affected, potentially leading to decreased treatment efficiency and the possibility of permit violations related to discharge quality. Maintaining the temperature within the regulated limit ensures that the biological processes in the wastewater treatment system operate effectively and reduce the risk of negatively impacting the environment.

Other temperature thresholds may be higher, but they exceed the regulatory limits set to maintain optimal conditions for wastewater treatment processes.
