Grease Trap Requirements
Dubuque, IA

FOG Compliance in Dubuque, IA

Food service establishments in Dubuque operate under a combination of federal EPA pretreatment standards, Iowa 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.

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 Dubuque 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.

Dubuque requires a dedicated FOG permit for any food service establishment generating fats, oils, and grease. The permit is separate from, and in addition to, the plumbing permit required at installation.

Establishments must maintain pumping logs, hauler manifests, and inspection reports on-site — missing records is itself a violation in most enforcement actions.

Specific pumping schedules and compliance thresholds for Dubuque are not published in the municipal code at the level of detail tracked on this site. Restaurant operators in Dubuque should contact the local wastewater utility directly to obtain the current rule set before installation or during inspection preparation.
