Restaurants and food service facilities in Knoxville that discharge to the KUB sewer system follow the Knoxville Utilities Board (KUB) grease trap standards. Here’s a plain-language summary of the key maintenance requirements.
How often must grease traps be cleaned in Knoxville?
- At least once a month, unless KUB approves a different schedule in writing.
- Weekly solids checks by your own staff.
- The 25% rule: it counts as a violation when the grease and food solids together reach 25% or more of the trap’s capacity, so busy kitchens may need service more often than monthly.
What records should you keep?
KUB’s standards say maintenance logs and hauler manifests for the previous 12 months should be kept on site, so they’re ready when an inspector asks.
Who pays for maintenance?
The business that uses the grease trap is responsible for maintaining it at its own expense.
