How is an interceptor typically described in plumbing?

An interceptor is fundamentally identified as a separator intended to manage hazardous waste, which can include substances that could be damaging to the plumbing system or the environment. Its primary role is to separate certain types of waste, such as oil, grease, or sediments, from wastewater before it enters the main sewage system. This is particularly important in commercial settings like restaurants or garages, where the levels of such pollutants may be higher.

The function of an interceptor ensures that the hazardous components are retained and do not contaminate the municipal sewer system, thereby meeting environmental regulations and protecting the infrastructure. This clear distinction of purpose is what defines an interceptor in plumbing systems, aligning it with the critical need for waste management and environmental safety.
