What does POTW stand for?

• A. Publicly owned transit and wastewater
• B. Private owned treatment works
• C. Publicly owned treatment works
• D. Potential wastewater outlet works

Answer: (C)

POTW stands for Publicly Owned Treatment Works. This term is used in wastewater management to describe a treatment facility that is owned by a public entity, such as a city, county, or other government unit, and is responsible for collecting, treating, and discharging municipal wastewater. The “works” include the treatment plant and the interconnected sewer system. Understanding this helps distinguish POTWs from privately owned treatment facilities, and it’s a common term in environmental regulations related to wastewater, such as pretreatment programs and NPDES permitting. The other options either imply private ownership, bring in unrelated concepts like transit, or use a phrase that isn’t used in this context, so they don’t fit.
