Liquid trade waste means all liquid waste produced from a business, commercial or industrial activity other than sewage of a domestic nature (i.e. liquid waste from toilet, hand wash basin, shower and bath wastes). Specific activities that have been identified as liquid trade waste include, but are not limited to:
- Business/commercial premises (e.g. beautician, florist, hairdresser, hotel, motel, restaurant, butcher, service station, supermarket, dentist)
- Community/public premises (including craft club, school, hospital and nursing home)
- Industrial premises
- Saleyards, racecourses, stables and kennels not associated with domestic households
Sewerage systems are generally designed for waste from domestic sources that are of a predictable strength and quality. Liquid trade waste places much greater demands on Council’s sewerage system and can impact on the public, the environment and the sewerage system if not managed properly. For example, grease, oil and solids can build up causing blockages and sewer overflows; and strong wastes can cause corrosion of the sewerage system or produce offensive odours to the public.
