POTW stands for what?

• A. Public Organization for Water
• B. Polluted Water Treatment Works
• C. Public Office of Wastewater
• D. Publicly Owned Treatment Works

Answer: (D)

POTW refers to a Publicly Owned Treatment Works. The acronym matches the four words: Publicly, Owned, Treatment, Works. This term is used for wastewater treatment facilities that are owned by a public entity—usually a municipality or other government entity—and regulated under environmental laws like the Clean Water Act. Ownership matters because regulatory responsibilities, funding, and permit requirements typically hinge on whether the facility is publicly owned. The other options don’t reflect the standard terminology used in wastewater management, so they aren’t correct.
