Grease Trap Requirements
Gainesville, FL

FOG Compliance in Gainesville, FL

Food service establishments in Gainesville operate under a combination of federal EPA pretreatment standards, Florida state plumbing code, and city-level FOG ordinances. Together these rules determine how grease traps must be sized, how often they must be pumped, and what happens when a restaurant falls out of compliance.

Pumping frequency is the compliance rule restaurant owners interact with most often. In Gainesville, the rule is: Grease traps: minimum twice per month. This places it among the strictest tier of US jurisdictions, alongside most of Houston-area and high-volume Los Angeles County restaurants. The city follows the International Plumbing Code (IPC) for trap sizing and installation. Under Section 1003.3.4, which sizes traps by drainage fixture unit counts, grease interceptors installed in Gainesville must meet minimum capacity thresholds based on the fixtures connected to them — 3-compartment sinks, dishwashers, pre-rinse stations, wok stoves, and floor drains on the cook line. The local minimum trap size is: Per Florida Plumbing Code and GRU specifications.

Gainesville requires a dedicated FOG permit for any food service establishment generating fats, oils, and grease. The annual permit fee is $300 variance application fee (for variance from pumping requirements). The permit is separate from, and in addition to, the plumbing permit required at installation. Violations carry maximum penalties of $1,000 per day per violation (per Gainesville Code Section 27-180.7(h)) , in line with typical US municipal penalties. Fines typically escalate with repeat violations, and severe discharges that cause sanitary sewer overflows can trigger federal Clean Water Act penalties layered on top of local fines.

Gainesville enforces the 25 percent rule: grease traps must be pumped before the combined FOG and settled solids reach 25 percent of the trap's total liquid depth. Inspectors measure the depth with a sludge judge or dipstick, typically at surprise visits. Exceeding the threshold at inspection triggers a notice of violation and mandatory emergency pump-out, regardless of the scheduled pumping cycle. Periodic per GRU Oil and Grease Management Program; sample site must be accessible. Establishments must maintain pumping logs, hauler manifests, and inspection reports on-site — missing records is itself a violation in most enforcement actions. Enforcement authority rests with the Gainesville Regional Utilities (GRU) - Oil and Grease Management Program, which handles permit issuance, inspections, and hauler licensing.
