Etymology

Origin of sewer¹

First recorded in 1375–1425; late Middle English suer(e) “drainage ditch,” from dialectal Old French se(u)wiere “overflow channel, pond sluice” (compare Old French ess(e)ouer(e) “ditch”), from unrecorded Vulgar Latin exaquāria “drain for carrying water off,” equivalent to Latin ex- “out of, away” + aquāria “pertaining to water” (feminine singular of aquārius ); -ary ( def. ), -er ², sew ²

Origin of sewer³

First recorded in 1350–1400; Middle English sever(e), sewerer “attendant who served or tasted his master's food,” shortened form of Anglo-French asseour “one who sets the table, seater,” equivalent to Old French asse(oir) “to seat” (from Latin assidēre “to attend upon”) + -our; assiduous, -or ² )

Explanation

Like so many superheroes, Teenage Mutant Ninja Turtles live in a sewer, the system that carries waste and water from buildings, houses, and mad scientists’ labs. The water that runs down a storm drain also ends up in a sewer. After you take a shower, or wash dishes, or flush the toilet, that used waste water runs through pipes away from your house. It travels either to a small septic system, or to a larger, city-wide sewer system, where it's treated to make it safe and clean enough to release into the environment. The origin of sewer can be traced to the Old North French sewiere, "sluice from a pond," or "something that makes water flow."
