Each regulator will have different obligations to make when it comes to wastewater compliance.
"Commercial trade waste contains large amounts of food, fats, oil, and grease. South East Water recently modified their criteria for Food and Oil Interceptors (FOI), aka grease traps, to align with Yarra Valley Water and City West Water. Trade waste agreements for commercial customers are based on the nature of the business, the number of kitchen fixtures that generate waste, and seating capacity."
"Industrial trade waste agreements apply to manufacturers, car washes, workshops, laundries, and chemical plants. Customers must provide a detailed description of their process including all chemicals and potential wastewater contaminants. South East Water will review MSDS information as well as process diagrams to identify pre-treatment solutions and trade waste agreement conditions."
