What produces liquid trade waste?

• Industries
  
• businesses and commercial premises such as beauticians, florists, hairdressers, hotels, motels, restaurants, takeaway stores, butchers, service stations, supermarkets, dentists
  
• community/public premises such as craft clubs; schools; colleges; education facilities; hospitals and nursing homes
  dairies, piggeries and cow sheds
  
• Trade activity such as mobile carpet cleaners, graffiti removalists
  Saleyards and racecourses, stables and kennels that are not associated with households
  
• Any commercial activity carried out at a residential premises

Do I need to apply for Liquid Trade Waste approval?
If your business discharges liquid waste other than domestic sewage from a hand wash basin, shower, bath or toilet then you are required under the Local Government Act to submit a Liquid Trade Waste Application to Council for approval.

Why control liquid trade waste?

Sewerage systems mainly collect waste from houses. However, these systems may also be capable of accepting liquid trade waste, provided that the discharges are planned, known and within accepted limits.

It is, therefore, important for Council to regulate liquid trade waste discharges, so that the waste does not:

• Cause problems for the sewerage treatment processes
  
• Compromise the health and safety of council workers
  
• Damage council’s infrastructure and assets
  
• Significantly increase maintenance costs
  
• Overflow the system
  
• Cause significant odour complaints
  
• Harm the environment
  
• Harm public health and safety
  
• Degrade effluent and biosolid quality and management
