raw sewage

Untreated human waste

Raw sewage is untreated wastewater—human waste, household drainage, and industrial discharge before any processing or purification.

The adjective raw distinguishes it from sewage that has passed through treatment facilities.

Raw sewage carries pathogens and contaminants, making its presence a public health concern: Raw sewage flowed into the river after the pipe burst.
