Sanitary Sewer
A sanitary sewer is the main pipe system that carries wastewater from homes and buildings to treatment facilities. It's different from storm sewers, which only handle rainwater. When plumbers mention this in their resumes, they're referring to their experience working with these essential systems that connect household plumbing to the city's main wastewater system. This is a critical part of any building's plumbing infrastructure and requires specific knowledge and certifications to work on. You might also see it referred to as a "wastewater line" or "sewer main."
