What is the term for the discharge from latrines, urinals, bathrooms, kitchens, and stables?

The term for the discharge from latrines, urinals, bathrooms, kitchens, and stables is sewage. This refers specifically to the liquid waste and any solids that are flushed or washed away through the plumbing systems associated with sanitation facilities. Sewage typically consists of water, feces, urine, and other organic waste, making it a comprehensive descriptor for the byproducts of human and animal activities related to sanitation.

While refuse refers to solid waste materials, and wet refuse may imply waste that contains some liquid content, neither specifically captures the broad range of waste products associated with sanitary systems. Waste water, while it does pertain to water that has been used and is thus contaminated, is a more general term that may not exclusively refer to the discharge from the systems mentioned. Thus, sewage is the most precise answer regarding the type of discharge specified in the question.
