sanitary sewers
Underground waste pipes
Sanitary sewers are underground pipes that carry wastewater from toilets, sinks, and drains to treatment facilities.
The term distinguishes them from storm sewers, which handle rainwater runoff.
Combined systems carry both, but most modern infrastructure separates them: The city is replacing its combined sewers with separate sanitary and storm systems.
