Disposal of Liquid Trade Waste

The correct disposal of liquid trade waste is important to ensure the longevity and vitality of our sewerage systems. Liquid trade waste is defined as all liquid waste other than sewage of a domestic nature (Local Government (General) Regulation 2005).

Pouring trade waste down the kitchen or bathroom sink can have a significant impact on the effectiveness of the sewerage treatment process and the health of the local environment. 

Any business that needs to dispose of liquid trade waste must contact Council to set up a service contract based on the Trade Waste Classification your business falls under. See liquid trade waste and classifications.

Council’s Liquid Trade Waste Inspector can provide the most up-to-date information on any pre-treatment and approvals that are required for the discharge of liquid trade waste into Council's sewerage system.  This should be done prior to discharging liquid trade waste to our sewerage systems without approval or correct pre-treatment where required, to avoid any penalties.

For further information refer to our Liquid Trade Waste information sheet  Trade Waste Info Sheet Nov 20103MB pdf(PDF, 3MB).

Trade Waste Policy

Council’s Trade Waste Policy outlines the proper handling and disposal of liquid trade waste for businesses. The policy limits the amount and type of liquid waste permitted into local sewerage systems, and ensures commercial users of the system pay the costs incurred in handling these wastes.  Businesses that do not adhere to the guidelines in the policy could receive a fine of up to $2000.

Monitoring Trade Waste

Council has a Trade Waste Inspector to approve, advise, monitor, sample and inspect trade waste discharged to the sewer. 

Monitoring is carried out on approved trade waste discharges, and samples are taken for laboratory testing and analysis.  The technology utilised by Council in this monitoring process can provide specific breakdowns of individual pollutants and their chemical makeup.  Wastes can therefore be treated and traced back to their original source.
