The correct identification of domestic wastewater that travels through a sewer system to a Publicly Owned Treatment Works (POTW) is crucial for understanding waste classification. Domestic wastewater is generated from residential sources and includes a combination of water and organic waste.

When it comes to categorizing this type of waste, domestic wastewater is not classified as solid waste, which typically refers to discarded materials such as garbage, refuse, and other solid materials that are not liquid in nature. Solid waste includes things like food scraps, packaging, and yard waste, which are distinct from the liquid and semi-liquid character of domestic wastewater.

Furthermore, domestic wastewater is also not considered hazardous waste unless it contains specific toxic, corrosive, or reactive constituents that meet the definition of hazardous waste as outlined by regulatory agencies. Hazardous waste typically poses substantial or potential threats to public health or the environment due to its quantity, concentration, or physical, chemical, or infectious characteristics.

Therefore, domestic wastewater is characterized as sewer waste but does not fall into the categories of solid waste or hazardous waste, supporting the conclusion that it belongs in the category of sewer waste and is not classified as either solid or hazardous waste. This understanding emphasizes the distinctions between different waste types and reinforces the importance of proper wastewater management practices
