Trade waste is any liquid and any substances contained in it produced by an industrial or commercial activity at any business premises. Only liquid waste that conforms to our set limits will be accepted for discharge to sewer.
These limits are imposed because waste from many businesses and industries may contain materials that are potentially harmful to sewerage workers, the sewerage system and the environment.
Trade waste must not be discharged into our sewer, unless the owner of the premises from which trade waste is discharged has been granted a trade waste approval.
