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.

Exceptions

The Director – Water and Sewerage Regulation, NSW Department of Industry Water has granted consented for some commercial activities from the requirement to apply for liquid trade waste approval. The businesses identified in this category must still meet the standard requirements identified in the exemption list.

What is your responsibility as a local business or property owner?

If you are discharging LTW into the Council sewerage system, you need to complete a Liquid Trade Waste Application to obtain approval. Either the owner of the premises or the tenant who carries out an activity on the premises may apply for approval. The tenant must have the property owner’s written consent in order to apply for approval. A discharger is responsible to pre-treat liquid waste to a level acceptable for discharge to the sewer. To assist applicants, Council can provide fact sheets on the type of business and pre-treatment needed for various LTW generating activities.

Fees and charges

Due to the amalgamation of the former Wyong and Gosford Councils, some liquid trade waste fees need to be aligned. This alignment will take place with the next IPART submission due for release on 1st July 2019. Current charges for the two former Councils will stay the same.
