Why You Need a Grease Trap/Interceptor Permit
You need a Grease Trap/Interceptor Permit from the Buffalo Water Board and Sewer Authority because discharging fats, oils, and grease (FOG) directly into the city's sanitary sewer system is prohibited by law. The primary legal basis is the Buffalo Sewer Ordinance, Chapter 413 of the City Code, which mandates pretreatment for all commercial food service facilities. This ordinance enforces specific FOG discharge limits (typically 100 mg/L) to protect the municipal wastewater collection system and treatment plant from blockages and operational failures. Non-compliance means your facility is operating illegally from its first day of service.
Failure to obtain and maintain this permit triggers immediate enforcement actions by the Buffalo Water Board. Practical consequences include:
- Significant fines: Daily penalties for illegal discharge can accrue rapidly, starting from hundreds of dollars per violation.
- Cease-and-desist and service disconnection: The authority can order an immediate shutdown of your kitchen operations and disconnect your water/sewer service until compliance is achieved.
- Required remediation costs: You become financially responsible for cleaning any sewer line blockages caused by your FOG discharge, which often involves costly hydro-jetting or excavation.
- Insurance and lease implicationsMany commercial property leases require valid permits; violations can trigger default clauses. Insurance may not cover damages or business interruption resulting from a permit violation.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2026, the Buffalo Water Board has enhanced its inspection protocols for high-volume food establishments, requiring more frequent grease trap maintenance logs and potentially mandating automatic grease removal devices for new installations in certain districts.
Who Needs a Grease Trap/Interceptor Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required, as full-service kitchens produce fats, oils, and grease (FOG) subject to the Buffalo Sewer Authority (BSA) Sewer Use Ordinance § 431-32. |
| Bar / Nightclub | Required | Required if the establishment has a kitchen or prep area that generates FOG, as regulated by BSA Ordinance § 431-32 for commercial food service. |
| Food Truck | Required | Required, as mobile food preparation units with plumbing fixtures that discharge grease must comply with BSA requirements, typically via a portable interceptor. |
| Coffee Shop / Café | Required | Required if food preparation (e.g., sandwiches, pastries with butter/oil) occurs on-site, triggering the FOG control rules in BSA Ordinance § 431-32. |

25 of 30 auto-filledProperty Address
textEnter the full street address of the restaurant where the grease interceptor will be installed, exactly as it appears on your lease or property deed.
COMMON MISTAKE: Entering a P.O. Box, a corporate mailing address, or an incomplete address (e.g., missing suite or unit number).
Building Owner Name
textProvide the legal name of the property owner or the holding company listed on the property's title.
COMMON MISTAKE: Writing the tenant/restaurant business name instead of the building owner's legal name.
Owner Contact Information
textEnter the building owner's current phone number and/or email address for official correspondence.
COMMON MISTAKE: Providing outdated or incorrect contact details, or listing the tenant's contact information.
Total Fixture Load (Sanitary Piping)
textCalculate and enter the total fixture load in drainage fixture units (DFUs) for all kitchen fixtures (sinks, dishwashers, floor drains) connected to the grease interceptor.
COMMON MISTAKE: Underestimating the DFU count, which leads to specifying an undersized interceptor and automatic plan rejection.
Water Fixture Unit Count
textEnter the total number of water supply fixture units (WSFUs) serving the kitchen, used to verify water demand against drainage capacity.
COMMON MISTAKE: Confusing water fixture units with drainage fixture units (DFUs) and entering the wrong value.
Drainage Square Footage by Section
textList the total square footage of the kitchen area draining to the interceptor, broken down by distinct drainage sections or zones if required.
COMMON MISTAKE: Providing the restaurant's total square footage instead of just the kitchen's grease-producing drainage area.
Piping Pitch (inches per foot)
textSpecify the slope of the drainage piping leading to the interceptor, typically expressed as a fraction (e.g., 1/4" per foot), to ensure proper flow.
COMMON MISTAKE: Entering a pitch outside the Buffalo Plumbing Code's allowable range (e.g., too flat or too steep), which requires a design revision.
Gas Service Piping Size
textEnter the diameter (in inches) of the gas supply pipe that serves kitchen equipment, as shown on your approved mechanical plans.
COMMON MISTAKE: Leaving blank or entering 'N/A'; this field is often verified for overall utility coordination even on a plumbing permit.
Conductor Piping Trap Diameter
textSpecify the diameter (in inches) of the piping trap for the conductor (storm drainage) line, if separate from the sanitary system.
COMMON MISTAKE: Incorrectly entering the sanitary drain size here, or omitting the measurement if the system is combined.
Cleanout and Manhole Locations
textDescribe the physical locations of all proposed cleanout accesses and interceptor manhole lids relative to permanent kitchen landmarks.
COMMON MISTAKE: Providing vague descriptions (e.g., 'near sink') instead of measurable distances from walls or fixtures, which inspectors cannot verify.

Top 5 Grease Trap/Interceptor Permit Mistakes
1. Mistake Title
Based on ApronPrep's analysis of Grease Trap/Interceptor Permit applications in Buffalo, the most common error is submitting the wrong application type for your establishment's design. Buffalo's Department of Public Works, Parks & Streets classifies grease interceptors by flow rate and location (indoor vs. outdoor, gravity vs. automatic). Submitting an 'Outdoor Hydromechanical' form for a high-volume, indoor gravity system is an automatic rejection. This mistake adds 2–3 weeks to your timeline as the department returns the application and requires you to restart the process with the correct forms.
2. Incorrect Interceptor Sizing Calculations
Applicants often miscalculate the required grease interceptor size, leading to immediate technical review failure. Buffalo bases sizing on the fixture unit count and type (e.g., pot sinks, prep sinks, dishwashers) as defined in the NY State Plumbing Code. A common example is counting a three-compartment sink as one fixture instead of three, resulting in an undersized interceptor proposal. This error triggers a request for revised plumbing plans, delaying approval by 3–4 weeks while an engineer re-stamps the drawings.
3. Missing Plumbing Contractor & Master Plumber Details
The permit application requires the NYS-licensed Master Plumber and plumbing contractor who will perform the installation, including their license numbers. Applications submitted with 'TBD' or incomplete license info are placed on hold. For example, listing only the contractor's business name without the attached Master Plumber's individual license number (e.g., 'MP-12345') is insufficient. This omission adds 1–2 weeks of delay while you obtain and submit the correct credentials.

Prepare site drawing showing all exterior water, sanitary, storm, and gas piping
Create a detailed, scaled drawing of your property showing the exact location of all incoming and outgoing utility lines relative to your building foundation and property lines. You'll need your property survey and contractor layout plans. The most common rejection reason is missing the gas line location, which must be shown for safety clearances.
Prepare plumbing plan (P-drawing) showing all interior piping with sizes
Draft a professional plumbing diagram detailing pipe diameters (typically 2”, 3”, or 4” for grease interceptor lines), slopes (minimum 1/4” per foot), and all connections from sinks, dishwashers, and floor drains to the interceptor. You must include pipe material specifications (PVC, cast iron). Plans without labeled sizes are rejected immediately.
Calculate and document all drainage areas, fixture loads, and piping specifications
Use the Uniform Plumbing Code (UPC) fixture unit method to calculate total drainage load from all kitchen fixtures. You'll need appliance manuals for flow rates. Document every calculation — Buffalo requires the worksheet to be submitted. Underestimating the load is the #1 cause for undersized interceptor rejection.

See All RequirementsProcessing times vary significantly based on application completeness and the city's inspection schedule. According to the Buffalo Water Department, plan review can take 2-4 weeks before scheduling an inspection. After a successful inspection and the associated Building Permit finalization, your approval is typically issued within 10 business days.
There is no direct government filing fee for the permit itself, but you must pay for plan review and the required inspections. These costs are typically bundled within the fees for your main plumbing or building permit, which can range from several hundred to over a thousand dollars. Not legal advice — verify specific costs with the Buffalo Water Department and Permit Office.
No, grease trap permits are site-specific and cannot be transferred to a new address. Each new restaurant location requires a new application, plan review, and installation inspection. This process is similar to applying for a new Certificate of Occupancy, as both are tied to the specific property and its approved infrastructure.
The installation permit itself does not require renewal, but you must maintain the system. Buffalo requires regular maintenance, typically pumping and cleaning every 90 days for most establishments, and annual certification by a licensed waste hauler submitted to the Water Department. Failure to submit this certification can result in fines and enforcement actions.
A city plumbing inspector verifies the installation matches the approved plans, checking pipe sizes, venting, location, accessibility, and that the correct capacity interceptor is installed per Buffalo City Code § 301-13. The inspector will also ensure proper grading and that the unit is watertight. You must pass this inspection before final approval of your related plumbing or building permit.
