At the risk of sounding obvious, liquid waste is all waste that exists as a liquid rather than either a gas or a solid. Since the term encompasses all waste in liquid form, it includes both waste produced as a liquid and waste that has been converted into a liquid for handling. Similarly, it includes both liquid waste that emerges from a single source such as industrial wastes being pumped out through pipes and liquid waste that has no single source such as run-off caused by rainfall. Other common examples of liquid waste include both human and animal excreta plus household wastewater coming from bathing, dishwashing, and a range of other domestic activities.
