Liquid waste shall discharge into a ______ before entering the sewer.

Liquid waste shall discharge into a ______ before entering the sewer.

• A. Separator
• B. Trap
• C. Catch Basin
• D. Sump

Answer: (A)

The main idea here is that waste streams containing oils or greases need a treatment step before they go into the sewer. A separator serves that purpose by allowing the liquid waste to pass through while separating out contaminants such as fats, oils, and grease (and other floatables). This keeps the sewer lines clearer, reduces blockages and odor, and helps meet code requirements for discharging wastewater. A trap is designed to keep sewer gases from coming back into the building and is placed near a fixture, not to treat an entire waste stream before the sewer. A catch basin collects surface runoff rather than wastewater containing oils or greases. A sump gathers water to be pumped out and isn’t used to treat or separate contaminants before sewer discharge.
