What is the purpose of an interceptor in plumbing?

The purpose of an interceptor in plumbing is primarily to separate hazardous matter from normal waste. Interceptors, such as grease interceptors or oil interceptors, are specifically designed to capture and retain substances that could harm the wastewater treatment system or create safety hazards. For example, in commercial kitchens, grease interceptors prevent fats, oils, and grease from entering the sewage system, which can lead to clogs and environmental issues.

By removing these hazardous materials before they enter the municipal sewer system or a septic system, interceptors play a critical role in protecting the plumbing infrastructure and the environment. This separation helps to ensure that the waste being treated is more manageable and less harmful, contributing to more efficient wastewater treatment processes and compliance with environmental regulations.
