The discharge temperature for a Type IV interceptor should be limited to what maximum value?

The correct maximum discharge temperature for a Type IV interceptor is 140 degrees Fahrenheit. This regulation is significant because Type IV interceptors, often used in grease management applications in commercial kitchens, are designed to prevent hot wastewater from entering the sewer system directly. High temperatures can negatively affect the ability of the interceptor to function properly, leading to the potential for grease to solidify or other operational issues.

Maintaining a maximum discharge temperature of 140 degrees Fahrenheit ensures that the wastewater remains manageable within the interceptor and allows efficient processing of grease and solids. Additionally, this temperature limit helps protect municipal sewer infrastructure and treatment systems, as excessively hot wastewater can damage pipes and disrupt biological treatment processes at wastewater treatment facilities.

Understanding this limit is crucial for any plumbing professional or contractor working in compliance with local codes, such as those outlined in the Omaha Plumbing Code, to ensure both operational efficiency and adherence to environmental protection standards.
