What is trade waste?
Trade waste is waterborne waste from any commercial or industrial activity that is discharged to the sewer.
Trade waste excludes domestic wastewater, for example toilets, showers, hand washing and non-commercial kitchens.
The owner of the property is the trade waste approval holder, as per the Townsville City Council Trade Waste Management Plan. Property owners are charged separately on their rates notice for trade waste discharged to the sewerage system.
Who needs a trade waste approval?
The sewerage system is designed for domestic waste. The owner of a commercial, private or industrial property must have a trade waste approval if a business operating from the property discharges wastewater to the sewer (other than domestic wastewater, i.e. toilets, showers, hand washing and non-commercial kitchens).
Trade Waste Categories - Business types that require trade waste approval
Retail food - Category 1.1
Retail food outlets where greasy or oily water can be produced. These premises require a grease interceptor trap include — but are not limited to — restaurants, cafés, take-away food outlets, function centres, canteens, hospital and nursing home kitchens, caterers, butchers, delicatessens, retail bakeries, supermarkets and home caterers.
All new food licence applications/applicants must have a trade waste approval before operations commence. This excludes mobile food carriers and temporary stalls.
Automotive/engineering industry - Category 1.2
Automotive, mechanical and engineering businesses with vehicle and machinery wash bays that generate oily waste, including car sales and detailing businesses. Such premises usually require an oil separator and holding tank.
Other commercial activities - Category 1.3
These customers usually have a range of low concentration contaminants, including high temperature discharge and suspended solids. Businesses include commercial car washes, laundries, school art and science blocks and pet washes. The required pre-treatment depends on the business type.
Low risk food generators - Category 1.4
Food premises not discharging greasy or oily waste and there is no cooking on-site, such as sandwich bars, coffee shops, and canteens. These businesses usually do not require pre-treatment.
Multiple generators - Category 1.5
This is applicable when there is more than one type of trade-waste-generating activity on the property. Depending on the circumstances — and in consultation with the property owner — separate trade waste approvals may be issued (conditions apply).
Access fee only - Category 1.6
Business activities generating trade waste where the volume and concentrations are low and difficult to determine. A trade waste approval is required, but discharge volume fees will not be levied. The discharge quality must be within council’s sewer admission limits. An annual sewer access fees will apply.
These business activities include:
- funeral parlour
- dental surgery
- dental technician
- doctor's surgery
- x-ray clinic
- dry cleaners
- dog groomer, pet shop
- optical lens grinding
- bin or vehicle wash area (residential)
- chemical toilet waste disposal points e.g. Dump-Ezy
- pool/fountain filter backwash (other than commercial pools).
Industrial customers (Category 2) have a type of waste that:
- has varying concentrations of several different contaminants
- requires pre-treatment other than basic pre-treatment
- after pre-treatment, still has contaminants in concentrations that exceed council’s sewer admission limits.
Industrial generators may include, but are not limited to:
- food and beverage manufacturers
- industrial laundries
- chemical manufacturers
- petrochemical industries
- metal finishers
- waste processors
- laboratories (other than school laboratories)
Industrial customers are expected to install sufficient pre-treatment devices or systems to ensure the discharge quality meets council’s sewer admission limits. It is the responsibility of the approval holder to design the type of pre-treatment required, as well as the operation and maintenance strategy.
The proposed facility will be assessed as part of the approval process.
Risk rating assessment
Each trade waste application will be assessed for the level of risk that the discharge poses to the sewerage system, including its impact on infrastructure, the treatment process, the quality of the effluent or bio-solids, the health and safety risks, and the risk of non-compliance events.
The assessed risk rating is used to prioritise trade waste management activities, guide the assessment process, influence the approval term and determine the annual access fee.
The majority of customers are Risk Rating 5, requiring twice-yearly inspections. For more information about categories and risks, refer to the Trade Waste Management Plan.
Sewer admission limits
How to apply for a trade waste approval
You must apply for a trade waste approval when new trade waste is generated and discharged to council’s sewerage system from your premises.
Applicants are encouraged to contact council early in a project cycle to ensure required pre-treatment equipment is appropriately designed and installed. Council does not take any responsibility for new developments that have inadequate or under-sized pre-treatment.
A trade waste approval must be issued before any associated hydraulic approval is granted or operations under a food licence commence.
Trade waste charges
To recover the cost of managing the additional load trade waste imposes on the sewerage system, trade waste charges apply. Charges are based on the nature of the waste generated and the risk that the discharge poses to the sewerage system.
Each customer is charged an annual access fee and, in most cases, a volume charge, levied on the twice-yearly council rate notices as a utility charge.
For more information, see the Trade Waste Charges Information Sheet.
