Which of the following describes an interceptor?

An interceptor is a device specifically designed to separate and remove hazardous materials from waste streams, preventing them from entering the public sewer system. This function is crucial for protecting wastewater treatment facilities from contamination and ensuring that harmful substances do not interfere with the treatment process.

In the context of plumbing and waste management, interceptors are commonly used in applications involving grease, oil, and other pollutants, particularly in commercial kitchens and automotive repair shops. By capturing these materials before they can enter the sewage system, interceptors help maintain the integrity of the plumbing infrastructure and minimize environmental impact.

The other options provided, while related to waste management and treatment, do not accurately describe the function of an interceptor. A tank that holds sewage before disposal refers to a septic tank, which serves a different purpose in managing wastewater. A type of water filter pertains to systems designed to purify drinking water rather than separate hazardous waste. Lastly, a sewage treatment plant processes waste but does not focus specifically on the separation of hazardous materials, which is the primary role of an interceptor.
