Why You Need a Water and Sewer Connection Permit
You cannot legally receive water and sewer service for a commercial kitchen without a Water and Sewer Connection Permit from San Antonio Water System (SAWS). This is a mandatory condition of connection, governed by SAWS’s Sewer Use Regulations (Section 3.04), water main connection policies, and City of San Antonio ordinances covering street/sidewalk cuts and grease abatement. The permit formalizes your agreement to comply with discharge limits for fats, oils, and grease (FOG) and other contaminants, and ensures the physical connection meets engineering standards. Without this documented approval, SAWS will not activate your meters, which means you cannot test plumbing, run equipment, or pass your final health inspection.
Operating without this permit or violating its terms carries significant, immediate consequences for a restaurant:
- Service Disconnection: SAWS can physically shut off water and sewer service to your business for non-compliance, resulting in an immediate forced closure.
- Fines and Required Remediation: You face daily administrative fines from SAWS for unauthorized discharges. More critically, you will be responsible for the cost of cleaning any sewer blockages caused by your establishment and any related public works repairs, which can run into thousands of dollars.
- Permit Revocation & Lease/Insurance Issues: Your Certificate of Occupancy can be suspended if utilities are not properly permitted. Furthermore, a utility service disconnection is a common lease violation that can trigger default, and many business insurance policies void coverage for losses stemming from unpermitted work or code violations.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: In 2024, SAWS integrated its permit application portal more closely with the City’s Development Services Department (DSD), requiring simultaneous submission of right-of-way permits for any work in public streets or sidewalks.
Who Needs a Water and Sewer Connection Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required per San Antonio Water System (SAWS) regulations because it connects new or existing plumbing fixtures to the public water and sewer mains. |
| Bar / Nightclub | Required | Required as all establishments with restrooms and sinks must obtain a new connection permit when plumbing is installed or modified, following San Antonio City Code § 34-4. |
| Food Truck | Not Required | Typically not required for a mobile unit; instead, operators must obtain a Temporary Service Permit for water supply at an approved commissary or mobile food unit dump station, governed by SAWS Mobile Food Unit Guidelines. |
| Coffee Shop / Café | Required | Required because any business installing commercial-grade plumbing for espresso machines, sinks, and restrooms needs a permit to connect to the city's water and sewer system. |

37 of 45 auto-filledBusiness Legal Name
textEnter the official, registered name of your business entity exactly as it appears on your Texas Secretary of State filing or assumed name certificate (DBA).
COMMON MISTAKE: Using the restaurant's 'doing business as' (DBA) or trade name when the city requires the formal legal entity name, which causes a mismatch with their records.
Type of Business
selectSelect the category that best describes your primary business activity, such as 'Restaurant - Full Service,' 'Fast Food,' 'Catering Service,' or 'Bar/Tavern,' as this determines water usage calculations and required pipe sizing.
COMMON MISTAKE: Selecting a generic category like 'Retail' instead of the specific restaurant classification, which can trigger a manual review for correct fixture unit calculations.
Property Address
addressEnter the complete physical street address of the restaurant location, including suite or unit number, as it is recorded with the Bexar County Appraisal District (BCAD).
COMMON MISTAKE: Providing a P.O. Box or an incorrect address format, which prevents SAWS from locating the correct property for utility mapping.
Tax Parcel ID
textProvide the 14-digit property identification number (e.g., 1234-56-789-0123) assigned by the Bexar County Appraisal District, which is essential for SAWS to verify property ownership and existing utility easements.
COMMON MISTAKE: Entering an old or incorrect parcel number from a preliminary title report, or confusing it with the lot/block number, which delays the application.
Property Owner Name
textEnter the full legal name of the individual or entity that holds title to the property, which must match the name on the most recent BCAD tax record.
COMMON MISTAKE: Listing a property management company or a trustee without the underlying legal owner's name, which fails the ownership verification check.
Property Owner Contact
textProvide a current phone number and email address for the property owner, as SAWS may contact them directly to confirm authorization for the connection work.
COMMON MISTAKE: Providing outdated contact information or the tenant's contact details, which stalls the verification process.
Applicant Relationship to Property
selectSelect your legal relationship to the property, such as 'Owner,' 'Tenant,' 'Authorized Agent,' or 'Contractor,' as this determines what supporting documents (like a lease or authorization letter) are required.
COMMON MISTAKE: A tenant selecting 'Owner,' which creates an immediate discrepancy with the submitted ownership documents and results in rejection.
Property Owner Authorization Letter
documentUpload a signed letter from the property owner authorizing you to apply for and perform water/sewer connection work, which is mandatory if the applicant is not the owner.
COMMON MISTAKE: Submitting an unsigned letter, a generic lease agreement instead of a specific authorization, or a letter from a property manager without proof of authority to act for the owner.
Applicant Name
textEnter the full name of the individual (not the business) submitting the application, who will be the primary point of contact for SAWS throughout the permit process.
COMMON MISTAKE: Entering the business name again instead of a responsible person's name, which causes confusion for SAWS communications.
Applicant Title
textProvide your official title or role (e.g., Owner, Manager, Project Coordinator) within the business applying for the permit.
COMMON MISTAKE: Leaving blank or entering 'N/A,' which can trigger a request for clarification and delay the application.

Top 5 Water and Sewer Connection Permit Mistakes
1. Incorrect Property Identification
Entering an informal address ('corner of Main and 1st') instead of the official lot and block number from your property deed. Applications with informal descriptions are routed to a manual research queue, adding 2-3 weeks to the initial review. Find the legal description on your property tax statement or the recorded plat from Bexar County.
2. Submitting Incomplete Utility Plats
Providing a site plan that shows the building footprint but omits the precise location of the proposed water and sewer tap points relative to the main lines. Without this, SAWS engineers cannot approve the connection design, causing immediate rejection. Hire a professional land surveyor to draft a utility plat that meets SAWS Technical Criteria Manual standards.
3. Miscalculating Meter and Tap Fees
Estimating water meter size based on fixture counts without using the SAWS Water Demand Calculator. An undersized meter fee calculation leads to a fee deficiency notice, halting permit issuance until the balance is paid. Use the official SAWS calculator for your specific use (restaurant, bar) to determine required meter size and the correct government filing fees.

Prepare Pre-Application Documents & Site Plans
Gather your site-specific construction plans, a detailed utility layout showing proposed water and sewer line tie-ins, a completed W-9 form for your business entity, and proof of property ownership or an authorization letter from the owner. You must also have your approved building permit number ready. This step often takes the longest for applicants who haven't yet finalized engineered site plans or lack clear property documentation from their landlord.
Submit Application Packet to SAWS Development Services
File your complete application packet through the San Antonio Water System (SAWS) Development Services customer portal or in person at their office at 2800 US Hwy 281 North. You must submit the official application form (SAWS Form #600), all site and utility plans, a copy of the building permit, and a completed W-9. Missing the signed W-9 is a common cause of immediate administrative rejection.
SAWS Engineering & Plan Review
A SAWS Development Services engineer will review your plans for compliance with the City's Water System Design Criteria and Sewer System Design Criteria. They will verify pipe sizing, meter location, backflow prevention requirements, and connection point specifications. Be prepared for a potential review comment cycle requesting plan revisions, which can add significant time if your initial plans do not meet code.

See All RequirementsThe timeline for this permit is officially listed as 'Varies' by the San Antonio Water System (SAWS). Processing depends on project complexity, plan review status, and inspection scheduling, which is typically coordinated after you have a valid Building Permit. Contact SAWS Development Services for a current project-specific estimate, as backlogs can add weeks.
Government filing fees for this permit are listed as $0–$0 per the official SAWS fee schedule. However, significant costs come from system development charges, meter installation fees, and required construction work, which are calculated based on your specific project scope and water meter size. For final project costs, you must request a detailed estimate directly from SAWS.
No. Permits are issued for a specific address and project scope and are non-transferable, as stated on the SAWS application. If you move locations, you must apply for a new connection permit for the new property, which may also require a new Certificate of Occupancy. Any fees paid for the original permit are forfeited.
You do not renew this permit. It is a one-time construction permit authorizing the physical connection to the city's mains. After final inspection and approval, your ongoing obligation is to maintain your private lateral lines and pay monthly utility bills. Separate annual requirements, like a Backflow Prevention Device Certification, may apply for commercial properties.
A SAWS inspector verifies the connection work complies with approved plans and the City's Uniform Plumbing Code. They check for proper pipe materials, trench depth, bedding, joint sealing, and that the connection is made at the designated point in the public main. Passing this inspection is mandatory before backfilling the trench and is a prerequisite for receiving water service to the building.
