sewer pipelines
Subterranean waste conduits
Sewer pipelines are underground conduits that carry wastewater from buildings to treatment facilities.
The term emphasizes the infrastructure as a network—miles of interconnected pipes beneath streets and neighborhoods: The city is replacing aging sewer pipelines downtown.
Municipal engineers and planners use the phrase more than ordinary speakers, who typically just say sewers.
