What does grease trap cleaning cost?
It depends mostly on what you have: a small indoor trap under the sink, or a large in-ground interceptor out back. Published 2026 figures put small systems around $175–$325 a visit and large interceptors around $350–$1,500.

Published price ranges (2026)
Figures from a published 2026 pricing guide, not FirstBearing quotes.
- Smaller grease management systems (indoor traps): about $175–$325 per visit
- Large outdoor interceptors: about $350–$1,500 per routine service
- Very large commercial or industrial systems: $2,000 or more per visit
What affects the price
- Trap or interceptor size, in gallons
- How full it is — overdue traps with heavy solids take longer
- Access: buried lids, tight alleys and distance from where the truck can park
- Disposal fees for the waste, which vary by area
- Emergency or after-hours calls for backups and overflows
- Recurring service — a set schedule usually costs less per visit
Comparing quotes fairly
- Ask whether they pump the whole trap, not just skim the top layer
- Ask for a service manifest or pumping record after each visit — many cities require you to keep them
- Ask where the waste is taken
- Ask what an emergency call costs, before you need one
Questions
Is a cheaper, more frequent schedule better?
Often. A trap pumped before it gets past about a quarter full is faster to service and far less likely to back up — which is the expensive call.
Can staff clean our small trap themselves?
Some cities allow it for small indoor traps if you keep a log; interceptors need a licensed hauler. Your city or wastewater utility sets the rules for your trap — many have a fats, oils and grease (FOG) program with their own schedule and paperwork. Check with them.
