water contaminated after human use
Water that people or industry have already used and that is now dirty with waste, and needs to be cleaned before it goes back to nature.
用法パターン：
wastewater from [a place/source]
よくある間違い：
Learners sometimes confuse "wastewater" with "wasted water." "Wastewater" is a technical noun meaning used, dirty water that needs treatment, while "wasted water" means clean water that was used carelessly or not needed. Learners may also use "sewages" as a plural; in standard English, "sewage" and "wastewater" are uncountable nouns and do not normally take a plural form.
類義語
sewage (Often refers specifically to household wastewater containing human waste, while "wastewater" can be broader, including industrial and agricultural sources.)
|
effluent (More formal/technical and often used for liquid waste that flows out of a factory or treatment plant.)
対義語
drinking water (Refers to clean, treated water that is safe for people to drink, the opposite of contaminated wastewater.)
