Grease Trap/Wastewater Disposal Registration in San Antonio, Texas (2026)
You can't open your kitchen doors until your restaurant's fats, oils, and grease (FOG) management plan is formally registered and approved by the San Antonio Water System (SAWS). This mandatory Grease Trap/Wastewater Disposal Registration, also known as a FOG Control Program permit, is a prerequisite for activating your SAWS water service for any food-service establishment. Without this completed registration, your site will not pass final plumbing inspection, delaying your Certificate of Occupancy and leaving you unable to operate legally. Most applicants complete this in under 15 minutes with ApronPrep, which auto-fills 0 of 0 fields.

Why You Need a Grease Trap/Wastewater Disposal Registration
The Grease Trap/Wastewater Disposal Registration in San Antonio is a mandatory operational permit required by the San Antonio Metropolitan Health District (SA Metro Health). Its authority is derived from the Texas Administrative Code, Title 25, Chapter 228 (Regulation of Food Service Establishments), which delegates enforcement to local health departments, and is further specified in the City of San Antonio's local health ordinances. This registration is not a one-time construction permit; it's an annual requirement that ensures your establishment's grease interceptor and wastewater systems are properly sized, maintained, and functioning to prevent fats, oils, and grease (FOG) from entering the municipal sewer system. Non-compliance is a direct violation of both state code and the city's wastewater pretreatment program managed by San Antonio Water System (SAWS).
Operating without a valid registration or failing to meet its conditions triggers immediate and escalating enforcement actions from SA Metro Health. Common consequences include:
- Fines and Re-inspection Fees: Administrative penalties and daily fines can be levied until the violation is corrected. You will also be responsible for paying for any required re-inspections.
- Cease-and-Desist and Closure Orders: Health inspectors have the authority to issue immediate closure orders for severe violations that pose a public health risk, halting all operations.
- Permit Suspension/Revocation: Your food establishment permit can be suspended or revoked, making it illegal to operate until you re-apply and pass a full compliance inspection.
- Insurance and Lease Complications: A closure order or permit suspension can void conditions of your business insurance policy and constitute a default under most commercial leases, putting your entire business tenancy at risk.
- Public Posting of Violations: In cases of significant non-compliance, a notice of violation may be posted at your establishment, damaging customer trust and your business's reputation.
Legal code: State food code (locally administered), local health regulations, state sanitary code
Recent update: In 2026, the San Antonio Metropolitan Health District integrated its grease trap permitting process with the SAWS Industrial Waste Permit system, requiring coordinated approvals and more detailed reporting on grease trap maintenance logs.
Who Needs a Grease Trap/Wastewater Disposal Registration?

|---|---|---|
| Restaurant (Full-Service) | Required | Required as a Food Service Establishment generating grease-laden wastewater, regulated under San Antonio City Code Chapter 34 and SAWS' FOG Program. |
| Bar / Nightclub | Not Required | Often exempt if no food preparation occurs on-site, but registration is required if a kitchen with grease-producing equipment is operated. |
| Food Truck | Required | Required; mobile vendors with an onboard grease interceptor must register with SAWS and comply with FOG Program requirements for discharge. |

1. Misclassifying Grease Trap Type or Capacity
Entering the wrong grease trap type (e.g., indoor vs. outdoor, gravity vs. automatic) or listing an incorrect capacity (in gallons) based on an old or estimated guess. The San Antonio Water System (SAWS) reviews this against plumbing plans, and a mismatch triggers a correction request, adding 10–14 days to your review timeline. Provide the exact specifications from your approved plumbing or engineering plans to avoid this.
2. Incomplete or Missing Hauler Documentation
Failing to attach the current, valid waste hauler contract or providing a generic service agreement that doesn't specify the San Antonio facility, frequency of service, and hauler's SAWS approval number. SAWS requires proof of a licensed hauler for the waste disposal plan section. Applications submitted without this are placed on hold, causing a 1–2 week delay. Use the contract from your SAWS-approved hauler that explicitly names your restaurant address.
3. Incorrect Facility/Service Address on the Form
Listing the business mailing address or owner's home address instead of the restaurant's physical location where the grease trap is installed. SAWS cross-references this with its utility account database. A mismatch leads to immediate rejection, as the registration is tied to the property's water service account, requiring a full re-submission. Double-check that the address matches your SAWS water bill exactly.

Prepare Required Documentation
Gather the core documents for a complete packet. You'll need your Texas Sales Tax Permit (or proof of application), a Certificate of Occupancy for the premises, a detailed site/plumbing plan clearly showing the grease trap location, and a notarized Industrial Wastewater Affidavit (available from the San Antonio Water System - SAWS). Missing the notarized affidavit is a top reason for application rejection, causing a 1-2 week delay.
Complete and Submit the IWWD Permit Application
Fill out the Industrial Wastewater Discharge (IWWD) Permit Application from SAWS, covering 45+ fields on business info, trap specifications, and waste volume estimates. This can be submitted online via the SAWS Business Portal or in person at their office at 2800 U.S. Hwy 281 N. You must include all prepared documents from Step 1. SAWS will not accept incomplete packets, leading to an immediate return.
Undergo Technical Review and Possible Inspection
A SAWS industrial waste inspector reviews your application and site plans to ensure compliance with the City Code, Chapter 34, Article VI. For new registrations or major modifications, they may schedule a pre-approval site inspection to verify trap sizing, location, and accessibility. This review determines if your operation is classified as a Significant Industrial User, which carries additional monitoring requirements.

See All RequirementsProcessing timelines for grease trap registrations vary considerably, depending on SAWS (San Antonio Water System) plan review and scheduling for the required on-site inspection. You should factor in time for any required construction or installation of the grease trap itself, which often requires a separate Building Permit. Contact SAWS's Environmental Services Department directly to confirm current processing estimates for new registrations.
The City of San Antonio and SAWS do not charge a direct government filing fee for the grease trap registration itself. However, you will incur costs for the grease trap equipment, its professional installation, and any required permits for that work. Not legal advice — verify with SAWS Environmental Services.
No, a grease trap registration is specific to the approved equipment and physical location. You must apply for a new registration at any new restaurant location. This process includes a new plan review and inspection, similar to the initial application, and you will also need a new Certificate of Occupancy for the new space.
Grease trap registrations in San Antonio do not have a standard annual renewal. Compliance is maintained through ongoing adherence to maintenance and cleaning schedules as mandated by SAWS rules. You are subject to periodic, unannounced inspections by SAWS personnel to verify compliance with these operational requirements.
A SAWS inspector will verify that the installed grease trap matches the approved plans, is properly sized for your facility's grease-producing capacity, and is correctly connected to the sanitary sewer. They will check for proper accessibility for maintenance and review your proposed cleaning and maintenance logs. Failure to pass this initial inspection will delay your ability to open for business.
