Liquid trade waste
Trade waste is treated differently to domestic wastewater, as it often contains oils, grease or chemicals that can have adverse impacts on the sewerage system or the environment.
Anyone wishing to discharge liquid trade waste to the sewerage system must, under Section 68 of the NSW Local Government Act 1993, obtain prior approval from Council.
Discharging liquid trade waste without approval is an offence under section 626 of the NSW Local Government Act, which may attract a maximum fine of $11,000.
What is liquid trade waste?
Liquid trade waste is all liquid waste other than domestic liquid waste discharged to the sewer. Domestic waste includes waste from a hand basin, shower, bath or toilet.
Liquid trade waste could be wastewater from any one of the following:
- Industrial premises
- Businesses and commercial premises such as; hotels, motels, restaurants, takeaway stores, butchers, service stations, mechanical workshops and supermarkets.
- Community and public premises such as; craft clubs, swimming pools, schools, education facilities, hospitals and nursing homes
- Any of the above activities carried out at residential premises
- Septic tank waste, waste from sites for the discharge of chemical toilet or pan contents from mobile homes, caravans or portaloos to the sewerage system.
Why is liquid trade waste regulated?
The Albury sewerage system (and most city/town sewerage systems) is designed for domestic sewage. Trade waste is generated by businesses or commercial activities and may be different to domestic sewage in terms of:
- pH (acidity or alkalinity of a solution)
- Temperature
- Presence of fats, oils and grease
Council regulates liquid trade waste discharges in order to:
- Protect the health and safety of those working in the sewerage environment
- Protect the health and safety of the public
- Protect our sewerage system infrastructure and assets
- Protect sewage treatment processes at our treatment plants
- Reduce maintenance costs of our infrastructure and assets
- Ensure regulatory and licence compliance to protect the environment
- Protect effluent and biosolid quality for facilitation of recycling.
