Reminder of Changes to Effect Trade Waste Businesses

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 prevention accredited plumbers. 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 available on the Council website
