What is the term for wastewater defined by the Federal Pretreatment Act as any non-domestic source?

The term defined by the Federal Pretreatment Act as any non-domestic source of wastewater is Industrial and Commercial Wastewater. This classification encompasses all wastewater generated from manufacturing processes, commercial operations, and other non-residential activities. These sources do not include typical residential effluents, which would fall under domestic wastewater.

Understanding this classification is important because it highlights the unique characteristics and treatment needs of industrial and commercial wastewater, which can have different physical and chemical properties than domestic wastewater. The Federal Pretreatment Act aims to regulate the discharges from these sources to prevent contamination of the municipal wastewater treatment systems and the environment.
