Why You Need a Grease Trap/Interceptor Permit
In Aurora, Illinois, a Grease Trap/Interceptor Permit is required under the city's Local Sewer Use Regulations and Water Connection Requirements to enforce compliance with the National Pretreatment Program (40 CFR Part 403). Specifically, the City of Aurora Municipal Code (e.g., Chapter 47, Sewers and Wastewater) and its plumbing and building codes mandate that any food service establishment discharging grease-laden wastewater into the municipal sewer system must install and maintain an approved interceptor. This permit is issued by the City of Aurora's Public Works or Water & Sewer Department and is a non-negotiable condition for obtaining or maintaining a Certificate of Occupancy. The regulations set strict grease discharge limits, typically measured in parts per million (ppm), to protect the city's infrastructure from costly blockages and to prevent sanitary sewer overflows.
Operating without this permit or failing to comply with its conditions triggers immediate enforcement actions. Consequences are severe and practical, impacting your daily operations and finances:
- Daily fines — Civil penalties are assessed per violation, per day, with amounts determined by the Public Works Director. Uncorrected violations can escalate to legal action.
- Service disconnection — The city can terminate your water and sewer service until compliance is verified, effectively forcing a shutdown.
- Required remediation — You will be liable for all costs to clean city sewer lines affected by your discharge and to bring your interceptor into compliance, including potential mandatory upgrades.
- Permit & occupancy revocation — Non-compliance can lead to the revocation of this permit and your business license/Certificate of Occupancy, voiding your right to operate at the location.
- Lease and insurance implications — Violations often constitute a breach of commercial lease agreements and can lead to non-coverage or premium increases from business liability insurers.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2026, the City of Aurora has increased emphasis on electronic inspection reporting and may require more frequent waste hauler documentation uploads as part of permit renewals to streamline compliance verification.
Who Needs a Grease Trap/Interceptor Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required because food preparation typically generates significant Fats, Oils, and Grease (FOG), triggering the city’s sewer use regulations for commercial establishments. |
| Bar / Nightclub | Required | Required if the establishment has a kitchen preparing food; bars without cooking equipment may be exempt, but must verify with Aurora Water. |
| Food Truck | Not Required | Typically exempt from a permanent grease interceptor permit, but must comply with mobile wastewater disposal regulations and may require a separate mobile handling permit. |
| Coffee Shop / Café | Not Required | Often exempt if operations are limited to beverages and pre-packaged foods with no on-site cooking; establishments with griddles or panini presses must apply. |

34 of 41 auto-filledBusiness Legal Name
textEnter the exact legal name of your business entity as registered with the Illinois Secretary of State or the IRS for your EIN, matching your Articles of Incorporation/Organization filing.
COMMON MISTAKE: Submitting a DBA (Doing Business As) or trade name instead of the registered legal entity name, which will be rejected by Aurora's Business License Division as they require verification against state records.
Federal EIN
textEnter your 9-digit Employer Identification Number (EIN) issued by the IRS, formatted as XX-XXXXXXX, without spaces or additional characters.
COMMON MISTAKE: Entering a Social Security Number for a sole proprietorship without employees; Aurora requires a federal EIN for all commercial grease trap permits, and using an SSN will cause a rejection.
Owner Name
textEnter the full legal name of the individual who holds at least 20% ownership interest or the managing member/officer of the business entity, as it appears on your driver's license or state ID.
COMMON MISTAKE: Submitting a manager's or attorney's name instead of the primary legal owner, which conflicts with Aurora's requirement for owner-level liability for the grease interceptor.
Owner Phone
textProvide a direct, working phone number for the owner listed above, formatted as (XXX) XXX-XXXX, which Aurora inspectors may use for urgent notifications regarding your interceptor.
COMMON MISTAKE: Providing a generic business line or disconnected number that fails Aurora's contact verification, which can delay the permit's issuance until a valid number is confirmed.
Owner Email
textProvide a valid, monitored email address for the owner, which Aurora uses to send official permit documents, inspection schedules, and renewal notices.
COMMON MISTAKE: Using an unmonitored or generic email (e.g., info@domain.com) that results in missed inspection notices, leading to a 'failure to respond' administrative rejection.
Facility Street Address
textEnter the complete physical street address of the restaurant or food service facility where the grease interceptor will be installed, as recorded in your lease or property deed.
COMMON MISTAKE: Submitting a P.O. Box or corporate headquarters address; Aurora requires the physical location for on-site inspection routing, and any mismatch will reject the application.
City
textEnter 'Aurora' exactly, as the permit is jurisdiction-specific and processed by the Aurora Water Department's Pretreatment Division.
COMMON MISTAKE: Entering a neighboring municipality like 'Naperville' or leaving blank, which routes the application to the wrong water authority and causes a jurisdictional rejection.
State
textEnter 'IL' or 'Illinois' in full, as required to align with the state environmental regulations enforced by Aurora under the Illinois Environmental Protection Agency (IEPA).
COMMON MISTAKE: Using an abbreviation like 'ILL' or entering a different state, which triggers a mismatch with the jurisdiction's database and stalls the application.
Zip Code
textEnter the correct 5-digit ZIP code for your Aurora facility, which the Water Department uses to assign your application to the correct inspection district.
COMMON MISTAKE: Entering a ZIP+4 or an incorrect ZIP that places your facility outside Aurora's municipal boundaries, causing a routing error and a 1–2 week delay.
Type of Food Service
selectSelect your primary food service category from Aurora's dropdown list (e.g., 'Full-Service Restaurant,' 'Fast Food,' 'Bakery,' 'Catering'), which determines your grease interceptor size and inspection frequency.
COMMON MISTAKE: Selecting a generic option like 'Other' without a detailed explanation, which requires manual review by an engineer and adds 10–15 business days to your approval timeline.

Top 5 Grease Trap/Interceptor Permit Mistakes
1. Submitting Incomplete Grease Interceptor Specifications
Applicants often list only the tank capacity or brand, missing required details like flow rate (GPM), grease retention capacity (in pounds), or connection size (in inches). The Aurora Public Works Department will reject the application, as they need all specs to verify the unit is sized correctly for your kitchen's projected grease waste. This adds 2-3 weeks for a resubmission cycle. Avoid this by having the manufacturer's specification sheet and your plumbing contractor's calculations ready before you apply.
2. Incorrectly Mapping the Grease Trap Location
Failing to provide a detailed, scaled site plan that clearly shows the interceptor's location relative to building lines, property boundaries, and all downstream sewer connections is a top rejection reason. A simple "in the kitchen" note is insufficient. Consequence: The review is halted until a compliant plan from a licensed plumber or engineer is submitted. Use a professional site plan that labels the trap, access points, and the entire waste line path to the city sewer main.
3. Mismatching Business Information with Other Filings
Using a DBA ("Doing Business As") name on the permit application that doesn't exactly match the name on file with the City Clerk's office or the Illinois Secretary of State causes administrative rejection. For example, applying as "Aurora Family Diner" when your legal entity is "Smith Restaurant Group, LLC" will delay approval. This requires a correction and re-verification, adding 1-2 weeks. Always use your business's exact legal name as registered with the state.

Gather Required Site and Equipment Plans
Assemble detailed site plans and specifications for your grease trap or interceptor. You'll need architectural or engineered drawings showing the plumbing layout, the trap's exact location, size, and capacity, and its connection to the sewer lateral. The City of Aurora's Development Services Department requires sealed plans for any new installation or major modification. Missing or illegible drawings are the most common reason for immediate application rejection, adding 2-3 weeks to your timeline.
Complete and Submit Permit Application Packet
Fill out the official city permit application form (available from the Development Services Department), attach all plans, and include the required payment for government filing fees. Applications are typically submitted in person or via the city's online permit portal if available. You must provide your business's legal name, address, contractor's license information, and the property owner's signature. Applications missing the property owner's approval are routinely returned unprocessed.
Plan Review by City Engineering
City engineers review your submitted plans for compliance with Aurora Municipal Code, Title 13 (Public Utilities), and the Illinois Plumbing Code. They verify the grease interceptor's sizing is adequate for your projected food service waste volume and that the installation meets all technical specifications. This review often involves back-and-forth requests for clarification or plan revisions. Do not proceed with any installation until you receive formal plan approval.

Based on official data, the government filing fee for this permit is currently listed as $0. However, you must still budget for the inspection, potential plan review fees, and related plumbing work. You will also need a separate Certificate of Occupancy before you can operate. Not legal advice — verify with the City of Aurora Building and Permits Division.
No, permits for grease control equipment are site-specific and cannot be transferred. The design and installation are approved for a specific plumbing layout and location. You must apply for a new permit at the new address, which will require submitting new plans and scheduling a new inspection per Aurora’s building codes.
A grease trap/interceptor permit is not a renewable annual license; it is a one-time construction permit for installation. Ongoing compliance is enforced through mandatory maintenance, record-keeping, and periodic inspections by the city. Failing maintenance can trigger enforcement actions and affect your City Business License/Registration. The inspection frequency is typically set by the local sewer use ordinance.
A city inspector will verify the installation matches the approved plans, checking the trap’s size, location, accessibility, and proper connection to the plumbing system. They will ensure all required components, like flow control devices and sampling ports, are present. Passing this inspection is a critical step before you can schedule a final inspection for your Certificate of Occupancy.
