Key Pricing Factors — Grease Trap
Trap Size
Larger traps take more time and tanker capacity. The single biggest cost driver.
Waste Volume
Heavily loaded traps or overdue services cost more than regularly maintained traps.
Access Conditions
Difficult lids, confined spaces, or no vehicle access add time and labour cost.
Scheduled vs Reactive
Regular scheduled services typically cost less per visit than ad hoc callouts.
Kitchen Volume
High-volume kitchens produce more FOG, meaning more waste per service period.
Urgency
Overflow or after-hours callouts attract higher rates than planned visits.
Septic Tank Pump-Outs
Septic tank pump-out pricing across the Illawarra is influenced by tank size, travel distance to rural properties, vehicle access, and how long it has been since the last service.

Key Pricing Factors — Septic Tank

System Type
ATUs and multi-chamber systems are more complex to service than standard tanks.
Urgency
Overflow or emergency callouts attract higher rates than routine maintenance visits.
Liquid Waste Removal
Commercial and industrial liquid waste removal pricing depends on waste type, volume, access, and any specific documentation or compliance requirements. Pricing is assessed on a per-job basis.

Grease trap waste, septic waste, and industrial wastewater have different handling and disposal requirements that affect cost.
