  • LIQUID TRADE WASTE INFORMATION

  • Trade wastewater from the motor industry contains petroleum hydrocarbons, solids, flammable liquids, metals and chlorinated solvents and phenols.
    These substances can:

  • * release flammable or explosive gases at the premises or in sewers
    toxic to aquatic life

  • * deteriorate mechanical equipment such as pumps and valves
    form deposits in the sewer and cause overflows
    accumulate in pumping stations, causing blockages
    cause overflows on your site

  • * contaminate sewage by-products
    interfere with sewage treatment processes
    toxic to humans, animals and plants

  • * Can be toxic to humans and damage plastic drainage fittings.

  • Council’s requirements and conditions for accepting trade wastewater helps to:

  • * protect people working in and around the wastewater system

  • * protect rivers, waterways and oceans from harmful discharges

  • * protect the wastewater system and treatment plants from damage

  • * encourage waste minimisation, cleaner production and water efficient practices.

  • The goal of local trade waste control programs, therefore, is to promote an appropriate
    service to industrial and commercial customers and to protect the community, the
    environment, the sewerage collection system and the wastewater treatment process from
    adverse effects which may occur when trade waste is discharged into a sewerage system.
    This protection can be achieved by regulating trade waste generators and ensuring that
    effective waste management practices and appropriate pollution control technologies are
    used.
