Best Practices for Maintaining a Grease Trap Data Log

Local health departments and wastewater authorities require that grease trap maintenance is not only performed regularly, but documented properly. A compliant grease trap log should include:

Date and Time of Each Service

Record every cleaning or inspection, whether it’s performed in-house or by a third-party provider like A-1 Tank Service.

Volume of Waste Removed

This helps track accumulation rates and can signal when you may need more frequent service.

Waste Disposal Method

Was it hauled offsite? Processed through an approved facility? Regulators want to see the full chain of custody.

Name of the Technician or Company

Always include the name of the person or service company who completed the work. This verifies credibility and accountability.

Signature of the Responsible Party

Whether it’s your maintenance lead or the service provider, a signed record adds legal protection.

Notes on Condition

Details like odor, blockages, or unusual waste levels can be important for future reference or troubleshooting.
