POTW stands for what?

• A. Publicly Owned Treatment Works
• B. Privately Owned Treatment Water
• C. Publicly Operated Treatment Workshop
• D. Publically Operated Transportation Works

Answer: (A)

POTW stands for Publicly Owned Treatment Works. This tells you the wastewater system is owned by a government entity—like a city or public utility—and that the network of facilities, including the treatment plant and associated sewer system, handles the collection, treatment, and discharge or reuse of municipal wastewater. The phrase “treatment works” is the traditional term for the infrastructure that treats sewage before it’s released back into the environment. Because these facilities are public, they’re subject to regulatory oversight and must meet water quality requirements under programs like the Clean Water Act. The other phrasings change ownership (private vs public), the meaning of what is being treated, or the type of facility, so they don’t describe the standard concept captured by POTW.
