What term describes the facility that collects and treats municipal wastewater?

• A. Treatment works
• B. Water filtration plant
• C. Industrial effluent plant
• D. Solid waste incinerator

Answer: (A)

The facility that collects and treats municipal wastewater is called a treatment works. This term refers to the plant that receives sewage from a sewer system and carries out the treatment process through multiple stages to remove contaminants before discharge or reuse. It’s the standard name for wastewater facilities, differentiating them from other types of plants: a water filtration plant handles potable water, not municipal sewage; an industrial effluent plant focuses on industrial waste streams; and a solid waste incinerator deals with solid waste rather than liquid wastewater. So, treatment works is the correct description.
