liquid waste
Sewage and wastewater
Liquid waste is any discarded material in fluid form—sewage, industrial effluent, contaminated water, or biological fluids requiring disposal.
The term appears in environmental regulations, waste management, and sanitation contexts: The facility must obtain permits before discharging liquid waste.
Distinguished from solid waste, though the two often require integrated handling.
