Liquid trade waste
Liquid trade waste means all liquid waste, other than domestic sewage, produced by a business, industrial or commercial activity, that is discharged to the sewerage system. It excludes domestic waste from a hand wash basin, shower, bath or toilet.
Due to its concentration levels, liquid trade waste may need pre-treatment before it is discharged into the sewerage system.
Liquid trade waste includes liquids from:
- businesses and commercial premises: eg, cafes, restaurants, hotels, service stations, mechanical workshops, supermarkets, beauticians, and butchers
- industrial premises
- community and public premises: eg, schools, hospitals, nursing homes, pools, and universities
- any of these activities carried out at residential premises
- trade activities: eg, mobile carpet cleaning
- septic tank waste
- chemical toilet waste
- waste from marine pump-out facilities and established sites: discharge of pan contents from portaloos, caravans and mobile homes to the sewerage system.
