Liquid Trade Waste and Classifications

Liquid Trade Waste means all liquid waste, other than sewage, of a domestic nature and includes liquid waste from:

  • Industrial premises
  • Business/commercial premises
  • Septic tank waste, marine pump-out or caravan dump facilities.

Liquid Trade Waste excludes:

  • Toilet, hand wash basin, shower and bath wastes from the above premises
  • Waste water from residential toilets, kitchen, bathroom and laundry (i.e. domestic sewage)
  • Common use (non commercial) kitchen and laundry in caravan parks.

Liquid Trade Waste Classifications

Classification A: Low Strength Waste

These are similar wastes to those from domestic situations. They may be waste activities from food outlets such as take-away shops, mechanical repairers and small restaurants. Through an Agreement between the business operator and Council, the operator undertakes the random measuring of waste water flow and sampling.

Classification A discharges have been divided into two broad groups:

  • Discharges from commercial retail food preparation activities/processes - discharges of less than 16 kilolitres per day from premises that conduct the selling of prepared food products directly to the public, including caterers.
  • Discharges from other commercial activities/processes – discharges not exceeding 5 kilolitres per day from premises that conduct businesses or provide services directly to the public. Examples include:
    • Animal wash activities
    • Boiler blowdown
    • Car detailing
    • Comfort cooling tower (non-industrial)
    • Craft activities
    • Dental surgery/dental technician/dental specialist
    • Doctor’s surgery, medical centre (plaster casts, no X-ray or laboratory)
    • Florist
    • Funeral parlours and morgues
    • Hairdressing/beautician
    • Jewellery shop
    • Laboratories (pathological and analytical only)
    • Laundry or laundromat (coin operated)
    • Lawnmower repairs
    • Mechanical repairs
    • Mobile cleaning units
    • Pet shop (retail).

If your business falls into this classification then complete the  Liquid Trade Waste Service Contract (Classification A)334KB pdf(PDF, 334KB) application form and submit to Council, including any supporting documentation. Once approved, trade waste discharge conditions will be formalised with you.

Classification B: Low Strength Waste

These are similar wastes to those from domestic situations. They may be waste activities from food outlets such as take-away shops, mechanical repairers and small restaurants. Through an Agreement between the business operator and Council, the operator undertakes the random measuring of waste water flow and sampling.

Classification B discharges are defined as:

  • Discharges that exceed the Classification A flow limit of 5 kilolitres per day or 16 kilolitres per day for commercial food preparation activities;
  • Discharge where the volume does not exceed 20 kilolitres per day;
  • More than four (4) concurrent Classification A liquid trade waste discharges from a single premises or a complex.

Commercial activities generating Classification B:

  • Automatic dismantler
  • Bus/Coach depot
  • Construction equipment maintenance and cleaning
  • Comfort cooling towers over 500 L/h (non-industrial)
  • Education facilities,
  • Tertiary institution (TAFE, University, etc.)
  • Equipment hire, maintenance and cleaning
  • Glass cutting and grinding
  • Hospital
  • Laboratory
    • dental
    • photographic
    • tertiary institution
  • Medical centre (with X-Ray)
  • Optical services at medical or educational facilities and workshops
  • Oyster processing – shucking
  • Panel beating
  • Photographic
    • waterwash minilab
    • graphic arts
    • X-ray (non-digital)
  • Radiator repair
  • Screen printing
  • Shopping complex
  • Vehicle washing (high volume, eg. drive through car wash, self-service car wash).

If your business falls into this classification then complete the  Liquid Trade Waste Service Contract (Classification B and C)341KB pdf(PDF, 341KB) application form and submit to Council, including any supporting documentation. Once approved, trade waste discharge conditions will be formalised with you.

Classification C: Industrial and Special Wastes

These are wastes not associated with normal domestic sector disposal. Regular monitoring is required to ensure pollutants are kept at a level below a minimum standard - these are typically discharges of a high risk or large volume. Activities which may produce wastes of this type include factory, large mechanical and processing services.

Under the stringent conditions set down by Council, the business operator is required to enter into an agreement whereby they carry out and meet the cost of regular monitoring and testing. Samples undergo laboratory testing and analysis to ensure all safeguards are being met. Periodically, random tests are also undertaken by Council staff to confirm adherence to the required standard.

Council's Trade Waste Inspector monitors and takes samples of trade wastes. Business operators are also able to seek advice and assistance on trade waste policy and regulations.

Classification C discharges are defined as:

  • Any Classification A or B discharge where the volume exceeds 20 kilolitres per day.
  • Any activity that is not nominated as Classification A, B or S.

Classification S: Septic Tank and Pan Waste

Classification S comprises pan content, septic tank pump-outs, chemical toilet waste and ship to shore pump-out units accepted for discharge into the sewerage system. Specific procedures need to be applied to their regulation as the waste is often transported or pumped from it’s source.

  • Septic - effluent and septage
  • Chemical and toilet waste
    • Pan content/night soil
    • Ship-to-shore pump-out from boats/marinas

If your business falls into this category then complete the  Liquid Trade Waste Service Contract (Classification S)342KB pdf(PDF, 342KB) application form and submit to Council, including any supporting documentation. Once approved, trade waste discharge conditions will be formalised with you.
