Why You Need a Grease Trap/Interceptor Permit
A Grease Trap/Interceptor Permit is legally required in Tucson before you can discharge any wastewater from your kitchen into the municipal sewer system. This requirement is based on the City of Tucson's Water Service Regulations and Sewer Use Code (most recently, Chapter 27 of the Tucson Code), as administered by the Tucson Water Department's Commercial Services division. These regulations exist to prevent fats, oils, and grease (FOG) from entering and clogging the public sewer lines, which can cause costly backups, environmental damage, and public health hazards. Your permit application demonstrates compliance with specific design, capacity, and maintenance standards for your interceptor system.
Operating a food service establishment without this permit carries significant and immediate consequences. The city's enforcement actions are designed to protect critical infrastructure and are not discretionary. Based on Tucson's established penalty structure, common consequences include:
- Service Disconnection: Tucson Water can terminate your water and sewer service until the violation is corrected, effectively shutting down your business.
- Substantial Fines: You will be subject to daily monetary penalties for non-compliance, which accrue until the issue is resolved. Fines can reach hundreds of dollars per day.
- Required Remediation: You will be responsible for all costs associated with cleaning the public sewer line if a blockage is traced to your establishment, which can run into thousands of dollars.
- Permit & License Revocation: Severe or repeat violations can lead to the revocation of your Grease Interceptor Permit and can jeopardize your broader business license, preventing operation.
- Lease & Insurance Implications: Violations can put you in breach of your commercial lease and may void provisions of your property or liability insurance if damage occurs from a preventable sewer backup.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2026, the City of Tucson has integrated its grease interceptor permitting process more closely with the Pima County Department of Environmental Quality's (PCDEQ) commercial kitchen review, requiring a coordinated submission for some new establishments to ensure compliance with both city sewer and county air quality regulations.
Who Needs a Grease Trap/Interceptor Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Generates significant fats, oils, and grease (FOG) and requires a grease interceptor per Tucson Code § 25-110. |
| Bar / Nightclub | Not Required | Only required if the establishment has a full commercial kitchen; bars primarily serving drinks with minimal food prep may be exempt from the permit per Tucson Wastewater Utility criteria. |
| Food Truck | Required | Required to have a licensed, permitted grease interceptor system connected to its commissary or a portable system, as all food trucks generate FOG subject to Tucson Code. |
| Coffee Shop / Café | Required | Required if the menu includes any food preparation (e.g., sandwiches, pastries) that generates grease, triggering the requirement under Tucson's FOG control program. |

Top 5 Grease Trap/Interceptor Permit Mistakes
1. Inaccurate Hydraulic Load or Flow Rate Calculation
Entering generic or estimated flow rates instead of calculating the total hydraulic load from all fixtures connected to the grease interceptor, using the Pima County formulas. This is the most common cause of permit rejection, as it can lead to an undersized and non-compliant system. Submit with the exact gallons-per-minute (GPM) calculations for all sinks, dishwashers, and floor drains, based on the fixture unit count per the 2026 Pima County Code.
2. Incorrect Interceptor Location on Site Plan
Failing to show the grease interceptor's precise location relative to property lines, building foundations, and other utilities on the scaled site plan. Tucson Water requires the interceptor to be accessible for maintenance (clear access lane) and within a specific distance from the kitchen fixtures it serves. A vague or missing location detail typically adds 2–3 weeks for plan review corrections. Mark the exact spot with dimensions from two permanent landmarks.
3. Omitting Manufacturer Specifications or Cut Sheets
Submitting the permit application without the manufacturer's specification sheet (cut sheet) for the proposed grease interceptor model. The City of Tucson Environmental Services Department requires proof that the unit's design, capacity, and certification meet Pima County Code standards (e.g., ASME A112.14.3). Applications missing this documentation are returned immediately. Attach the PDF spec sheet directly from the manufacturer’s website for the exact model number you are installing.

Call the PDSD to confirm the current permit packet and specific engineering standards, as local plumbing and environmental codes are updated periodically. Have your property address and intended FOG (Fats, Oils, and Grease) discharge volume ready for the inquiry. Failing to get the current year's plan review checklist is the top cause of initial packet rejection.
Complete the grease trap/interceptor permit application form
Fill out the city’s permit application (typically Form #B-1 or equivalent), providing details like contractor license numbers, equipment specs (size in gallons, flow rate), and installation location. ApronPrep auto-fills business details, but you must manually enter technical data from your plumber or engineer. Applications with conflicting flow rate and tank size data are rejected and require resubmission.
Gather required documents including engineering drawings and contractor information
Collect a site plan, detailed plumbing schematic (showing all fixtures discharging to the interceptor), and the licensed plumber/installer’s state license number and proof of insurance. The engineering drawings must be stamped by a professional engineer (PE) registered in Arizona and include calculations for sizing based on Tucson PDSD standards. Missing the PE stamp or contractor insurance certificate adds 1–2 weeks for document revision.

See All RequirementsProcessing times vary widely based on your application's complexity, project plan reviews, and city inspector workload. According to Tucson Water's permit guide, a simple installation review may take several weeks, while plans for a new facility with complex plumbing can extend review by several months. Contact the Tucson Water Industrial Waste Department to confirm the current timeline for your specific project type.
The government filing fees range from $520 to $5,550, per the City of Tucson's Unified Fee Schedule. The exact amount depends on the size, type, and capacity of the interceptor you're installing, as determined by your submitted plans. This fee is separate from other opening requirements like the Arizona Regulatory Licensing System (ARLS) Restaurant Registration. Not legal advice — verify final costs with Tucson Water.
No, these permits are site-specific and do not transfer. A grease interceptor is a physical component of a specific building's plumbing system, so a new location requires a new permit application and plan review. You must apply for a new permit at the new address, which triggers a new fee and inspection, similar to the process for an Alarm System Permit/Registration.
The installation permit itself is a one-time approval. However, your ongoing compliance is monitored through a separate annual Wastewater Discharge Permit and mandatory quarterly or semi-annual inspections. Failure to maintain the interceptor and pass inspections can result in fines and suspension of your discharge permit, putting your Arizona Liquor License (On-Premises) at risk if you hold one.
A Tucson Water inspector verifies the installation matches the approved plans, checks for proper sizing, location, accessibility, and that all plumbing connections comply with code. They will also ensure the interceptor is properly labeled and that required maintenance records are on-site. The inspection is pass/fail; failing adds significant delays, as you must schedule a re-inspection after corrections are made.
