What is liquid trade waste (LTW)?

LTW is a liquid waste produced by a business, commercial or industrial activity. It excludes domestic waste from a hand washbasin, shower, bath or toilet. It also excludes stormwater and unpolluted water. LTW includes liquids from:

  • industrial premises
  • business or commercial premises such as a café, hotel, motel, restaurant, butcher or supermarket
  • community/public premises such as schools, colleges, universities, hospitals and nursing homes
  • trade activities such as a mechanical workshop
  • any commercial activities carried out at a residential premises
  • saleyards and racecourses
  • septic tank waste, chemical toilet waste, waste from marine pump-out facilities and establishing sites for the discharge of pan content from mobile homes and caravans to the sewerage system.

While septic tanks, pan and ship-to-shore pump-out wastes are defined as trade waste, specific procedures need to be applied to their management as the waste is often transported from its source to the sewerage system.
