Trade waste is liquid wastewater from a food business or industrial entity that enters the sewer system. This includes all water that is used for the preparation or cooking of food, washing dishes or cleaning, that goes down the drain.
To protect the sewer system some trade waste may need to be treated before it is discharged. Treatment might include removing harmful chemicals or fats or can correct the characteristics of the wastewater, like its pH or temperature.
Whether your business is food related or industrial, you will be creating wastewater (or trade waste) that needs to be treated before it can be discharged to the sewer network.
