Lithgow City Council has a number of statutory responsibilities for the approval of liquid trade waste discharged to the sewerage system. A person wishing to discharge liquid trade waste must first obtain Council’s approval, as stated in Section 68 of the Local Government Act 1993. Under the Act, Council is responsible for the acceptance of these discharges. It is an offence under Section 626 of the Act for a person to discharge liquid trade waste to the sewerage system without obtaining an approval.

- Protecting river systems by reducing the amount of problem substances reaching treatment plants
- Improving wastewater quality reaching the sewerage treatment plants, allowing our treatment processes to work more effectively and efficiently and not be harmed by sudden shocks of toxic substances
- Preventing harmful substances from damaging the sewer, disrupting the sewerage treatment plant process or contaminating land and water
- Reducing sewer overflows and blockages by controlling the amount of grease discharged into the sewer
- Creating a safer workplace for people who work in and around the sewer

Backflow requirements for Trade Waste Discharges and Plumbers
Backflow prevention containment applies to all Lithgow Liquid Trade Waste discharges connected to Council’s potable water supply. The purpose of backflow prevention is to protect the water supply from contamination by liquid waste from commercial premises connected to the reticulated water supply. This can occur when contaminated liquid waste flows back through connections into the water supply system.
Commercial premises are responsible for ensuring the appropriate backflow prevention device is installed on their Grease Arrestor, Oil Water Separator or other approved pre-treatment device.
Council recommends all liquid trade waste discharges engage backflow accredited plumber. An accredited plumber will install and test the backflow device required relative to your hazard rating. Council has a list of backflow accredited plumbers in the Local Government Area
Backflow accredited plumbers wishing to be listed on the Council website must register with Council by providing a copy of the relevant plumbers license number and backflow accreditation.

Frequently Asked Questions
The provision of such a policy is mandatory to enable Council to meet the requirements of the Best Practice Management of Water Supply and Sewerage Guidelines, May 2004. This is critical as for Council to be eligible for subsidy under the Country Towns Water & Sewerage supply schemes (for funding upgrades of the Lithgow LGA sewerage treatment plants). Council was required to comply with the Department of Water & Energy’s Best Practice Management Guidelines including adopting an implementation of a Liquid trade Waste Policy.
