Recommended fields
A useful grease trap maintenance log should identify the asset, show when service happened, explain what was done, and preserve proof.
- Restaurant, location, trap name, trap type, and capacity.
- Service date/time, technician, service type, and condition before/after.
- Grease depth, solids depth, total liquid depth, and calculated percentage.
- Volume removed, disposal site, manifest number, invoice number, notes, and signatures.
Why digital logs help
Paper logs work until they are wet, lost, incomplete, or stored at the wrong location. A QR logbook keeps the record tied to the physical trap and makes export easier.
Recordkeeping disclaimer
Local requirements vary. Treat this as an operational template, not legal advice or a substitute for your local FOG program's required form.
Grease trap FAQ
Can a paper grease trap log still work?
Yes, if it is complete, legible, current, and easy to find. Digital QR logs reduce the risk of missing, wet, or scattered records.
