Why You Need a Grease Trap/Interceptor Permit

You need a Grease Trap/Interceptor Permit in Dallas because it is mandated by the City of Dallas Plumbing Code and the Wastewater Control and Use Ordinance (Chapter 49). These regulations, enforced by the Dallas Water Utilities (DWU) department, require any food service establishment that generates fats, oils, and grease (FOG) to install and maintain a properly sized and permitted interceptor. The specific standards for sizing, location, and installation are detailed in the Dallas Plumbing Code § P2701. Without this permit, you cannot legally connect your kitchen's plumbing to the municipal sewer system, and the city will not grant a final Certificate of Occupancy.

Operating without this permit or violating its conditions triggers immediate enforcement. Based on Dallas's standard procedures for sewer ordinance violations, the consequences include:

  • Substantial fines—often assessed per day of non-compliance until the issue is corrected.
  • Cease-and-desist orders or a service disconnection from Dallas Water Utilities, effectively shutting down your kitchen.
  • Required, costly remediation, which may involve cleaning the public sewer line you impacted and installing a larger or secondary interceptor at your expense.
  • Permit revocation, which can void your Certificate of Occupancy and breach your commercial lease or business loan covenants.
Failure to maintain your permitted system can also void property insurance claims related to sewer backups.

Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits

Service disconnection, fines, required remediation, permit revocation

Recent update: In 2026, the City of Dallas integrated its grease interceptor inspection reports into a centralized online portal, requiring digital submission of maintenance logs directly to DWU.

Legal Business Name

text
Auto-filled from compliance interview

Enter the exact legal name of your business as registered with the Texas Secretary of State or Dallas County Clerk; do not use a DBA or trade name unless it is the registered legal entity.

COMMON MISTAKE: Submitting a 'Doing Business As' (DBA) name instead of the registered legal entity name, which can cause the permit to be issued to the incorrect entity and become invalid.

High rejection risk

Physical Address (where grease trap located)

text
Auto-filled from compliance interview

Enter the complete street address of the restaurant facility where the grease trap/interceptor is physically installed; include the suite or unit number if applicable.

COMMON MISTAKE: Providing a mailing address, P.O. Box, or corporate office address instead of the physical service address, which violates Dallas Water Utilities' site-specific permit requirements.

High rejection risk

Business License/Permit Number

text
Auto-filled from compliance interview

Enter your City of Dallas Food Establishment Permit Number or Health Department License number; this is used to cross-reference your business records.

COMMON MISTAKE: Leaving this field blank or entering an incorrect, expired, or unrelated permit number (like a state sales tax ID), which delays verification.

Authorized Representative Name

text
Auto-filled from compliance interview

Enter the full name of the person authorized to sign for the business (e.g., owner, general manager, or corporate officer) who is legally responsible for permit compliance.

COMMON MISTAKE: Listing an employee without signature authority or using an incomplete name (e.g., 'Mike' instead of 'Michael Smith'), which can invalidate the application signature.

Equipment Type

text
Auto-filled from compliance interview

Specify the type of grease control device, such as 'Grease Interceptor', 'Grease Trap', 'Hydromechanical Grease Interceptor (HGI)', or 'Gravity Grease Interceptor (GGI)' as defined by Dallas City Code Chapter 49.

COMMON MISTAKE: Using vague or incorrect terms like 'grease container' or 'oil separator', which do not match the approved equipment categories in the municipal code.

High rejection risk

Tank/Trap Capacity (gallons)

text
Auto-filled from compliance interview

Enter the total liquid capacity in gallons, as stamped on the device's manufacturer plate or as stated in the plumbing installation plans; this determines your required pumping frequency.

COMMON MISTAKE: Estimating the capacity or using the flow rate instead of the static holding volume, which leads to an incorrect waste hauler schedule and violation of Dallas Water Utilities' maintenance rules.

High rejection risk

Has Grit Trap

checkbox
Auto-filled from compliance interview

Check this box if your plumbing system includes a separate grit or sediment trap installed upstream of the grease interceptor, as required for some high-volume establishments.

COMMON MISTAKE: Failing to check this box when a grit trap is present, which can result in an incomplete plumbing review and a request for additional information from inspectors.

Transporter on Approved List

checkbox
Auto-filled from compliance interview

Check this box to certify that your contracted waste hauler is currently on the Dallas Water Utilities' approved 'Fats, Oils, and Grease (FOG) Haulers List'.

COMMON MISTAKE: Checking this box without verifying your hauler's current approved status, which is a common cause for permit denial and can trigger a compliance audit.

High rejection risk

Transporter Company Name

text
Auto-filled from compliance interview

Enter the exact business name of your contracted grease waste transporter as it appears on the Dallas Water Utilities approved hauler list.

COMMON MISTAKE: Using a colloquial or abbreviated company name (e.g., 'Joe's Pumping') instead of the registered legal name (e.g., 'Joseph's Environmental Services LLC'), causing a mismatch during verification.

Transporter Address

text
Auto-filled from compliance interview

Enter the physical business address for your waste transporter, as listed with Dallas Water Utilities; this is used for official correspondence and compliance records.

COMMON MISTAKE: Providing a dispatch yard or driver address instead of the company's official headquarters address, which may not match the authority's records.

Top 5 Grease Trap/Interceptor Permit Mistakes

1

1. Submitting Incorrect Grease Interceptor Specifications

Listing a generic interceptor size (e.g., '1,000-gallon tank') without providing the exact manufacturer, model number, and calculated hydraulic retention time based on your fixture count. The Dallas Department of Public Works requires calculations per Plumbing Code Chapter 10 to verify sizing is adequate for your kitchen's grease load. Applications with missing or generic specs are returned for correction, adding 2–3 weeks to your timeline. Submit the manufacturer's cut sheet or a PE-stamped design with your application.

2

2. Providing an Inadequate or Unsealed Piping Schematic

Sketching a basic floor plan instead of a dedicated, scaled plumbing schematic that shows all fixtures (sinks, dishwashers, floor drains) connecting to the interceptor, including pipe diameters, slopes, and cleanout locations. The schematic must be sealed by a licensed plumber or professional engineer in Texas. Unsealed or unclear schematics are the #1 cause of administrative rejection, as reviewers cannot verify code compliance. Use the city's template or have your plumbing contractor provide the required drawing.

3

3. Miscalculating the Estimated Daily Grease Waste

Entering a guess (e.g., '50 lbs') instead of calculating waste based on the city's formula using your maximum meal capacity, type of food service, and number of seats. This figure determines pump-out frequency and compliance inspections. An inaccurate calculation can lead to a permit with an insufficient maintenance schedule, resulting in violation fines. Use the worksheet in the Dallas Grease Control Ordinance (Chapter 49A) to calculate and document your figures.

Identify a permitted liquid waste transporter from the City of Dallas approved list

You must select a waste hauler from the City's official 'Permitted Waste Transporters' list, which is maintained by Dallas Water Utilities (DWU). Do not use an unlisted company — this is a primary cause of violation notices. Verify the transporter’s permit is current via the DWU website before scheduling service.

1 hour
2

Schedule grease trap/interceptor pumping service every 90 days or when 25% or more of wetted height contains floating materials, sediment, oils, or greases

Mark your calendar for mandatory pumping every 90 days. Inspect the trap weekly; if floating materials fill 25% or more of the liquid depth, schedule immediate service regardless of the date. Failure to pump at this threshold is a common citation during inspections.

30 minutes (to schedule)
3

Schedule grit trap cleaning annually or more frequently as needed

Plan for at least one full cleaning of any grit trap per year. Kitchens with high-volume frying or baking may need quarterly service. Check your specific DWU permit for any mandated frequency based on your grease discharge rating.

FAQ

Processing time varies significantly based on application completeness, the need for plan reviews, and scheduling for the required inspections. According to the City of Dallas Water Utilities Department, plan review can take 2–4 weeks, with final approval coming after the Building Permit process and a successful installation inspection. It’s critical to submit complete, accurate applications to avoid timeline extensions.

The City of Dallas does not charge a separate, standalone government filing fee for a grease trap/interceptor permit. However, associated plan review and inspection fees are typically bundled into the broader mechanical or plumbing permit costs. Verify all applicable fees on the Dallas Development Services fee schedule, as total project costs depend on system size and complexity.

No. Grease trap permits are specific to the approved equipment and plumbing configuration at a single address. You must apply for a new permit at any new location, which includes submitting new site plans and scheduling new inspections. This is similar to the process for a Backflow Prevention Device Certification, where approval is tied to the physical installation.

The installation permit itself is a one-time approval, but ongoing compliance is enforced through mandatory servicing and maintenance reporting. Dallas Water Utilities requires licensed grease haulers to pump and clean traps regularly, with service reports submitted to the city. Failure to maintain records can result in violations, separate from your annual City Business License/Registration renewal.

A city inspector verifies the installed interceptor matches the approved plans, is correctly sized for your establishment's grease load, and is properly connected to the plumbing and sewer lines. They check for proper venting, accessible cleanouts, and that the unit is operational. Passing this inspection is a prerequisite for receiving your final Certificate of Occupancy. Not legal advice — verify specific inspection protocols with Dallas Water Utilities.
