Why You Need a Water and Sewer Connection Permit
Cincinnati restaurants must obtain a Water and Sewer Connection Permit before tapping into the municipal water supply or discharging wastewater into the public sewer system. This requirement is enforced under the Metropolitan Sewer District of Greater Cincinnati (MSD) Sewer Use Regulations and the Cincinnati Water Works (CWW) connection policies, which govern all commercial connections to city-maintained infrastructure. Restaurants that also discharge grease-laden wastewater are subject to MSD's Industrial Pretreatment Program, which sets enforceable limits on fats, oils, and grease (FOG) entering the sewer system. Any physical connection to the public right-of-way — including trenching through sidewalks or streets — additionally requires coordination with the Cincinnati Department of Public Services under applicable road and sidewalk ordinances.
Operating without a valid Water and Sewer Connection Permit exposes your restaurant to a range of serious consequences that can halt operations before you ever serve a single customer. The issuing authorities — MSD and CWW — have the power to deny or terminate service entirely, leaving your facility without running water or functional sanitation. Consequences include:
- Service disconnection — MSD and CWW may physically cut water or sewer access until a compliant permit is obtained
- Fines and penalties — civil penalties can accrue on a per-day basis for unpermitted connections or grease discharge violations; contact MSD directly to confirm current fine schedules, as amounts are not publicly posted in a fixed schedule
- Mandatory remediation — you may be required to excavate and remove unpermitted connections at your own expense before a lawful connection is approved
- Permit revocation — violations discovered during inspections can result in revocation of related operating permits, triggering a cascade of lease and insurance compliance failures
- Insurance and lease implications — most commercial leases and general liability policies require all utility connections to be fully permitted; an unpermitted connection can void coverage and constitute a lease default
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2025, MSD of Greater Cincinnati updated its Industrial Pretreatment Program requirements for food service establishments, placing heightened scrutiny on grease interceptor sizing and FOG discharge documentation at the time of connection permit application — contact MSD's Industrial Pretreatment department to confirm whether your planned connection triggers a pretreatment permit alongside the standard connection permit.
Who Needs a Water and Sewer Connection Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Any full-service restaurant connecting to Cincinnati Water Works' public water main or Metropolitan Sewer District of Greater Cincinnati (MSD) sewer system must obtain a Water and Sewer Connection Permit before initiating service, per MSD's Rules and Regulations governing new connections. |
| Bar / Nightclub | Required | Bars and nightclubs that dispense beverages and discharge wastewater into the MSD system require a connection permit, and high-volume establishments may also trigger a separate industrial pretreatment review under MSD's Pretreatment Program regulations. |
| Food Truck | Not Required | Food trucks operate as mobile units and do not make a permanent connection to Cincinnati's public water or sewer infrastructure; they are required instead to obtain potable water from an approved source and dispose of wastewater at a licensed dump station, making a fixed connection permit inapplicable. |
| Coffee Shop / Café | Required | Coffee shops and cafés require a Water and Sewer Connection Permit when establishing a new permanent connection to Cincinnati Water Works and MSD infrastructure, as any commercial food-service establishment with a fixed location that discharges to the public sewer system must be permitted under MSD's connection rules. |

54 of 65 auto-filledPreliminary Application Number
textEnter the PA number assigned by the Metropolitan Sewer District of Greater Cincinnati (MSD) when your preliminary application was logged — this is typically a 6–8 character alphanumeric code (e.g., 'PA-2026-00412') provided in your acknowledgment email or letter.
COMMON MISTAKE: Leaving this field blank or entering a project name instead of the official MSD-issued PA number will cause the form to be returned unprocessed, adding 2–3 weeks to your timeline.
Developer Name
textEnter the full legal name of the developer or development entity exactly as it appears on the project's deed, LLC registration, or corporate filing — do not use a trade name or DBA unless that is the registered legal name.
COMMON MISTAKE: Using an informal business name or abbreviation (e.g., 'Smith Hospitality' instead of 'Smith Hospitality Group LLC') can cause a name mismatch with MSD's ownership records and trigger a correction request.
Developer Street Address
textEnter the developer's official mailing street address (number and street name only, no city/state/ZIP — those go in the next field), as registered with the Ohio Secretary of State or the entity's primary place of business.
COMMON MISTAKE: Entering the project site address here instead of the developer's business/mailing address is a frequent error that causes correspondence to be sent to the wrong location and may delay permit issuance.
Developer City, State, ZIP
textEnter the developer's city, two-letter state abbreviation, and 5-digit (or 9-digit ZIP+4) postal code in a single line formatted as 'Cincinnati, OH 45202' — this field completes the developer mailing address block started in the street address field.
COMMON MISTAKE: Omitting the state abbreviation or using a full state name (e.g., 'Ohio' instead of 'OH') can cause formatting errors in MSD's database and may prompt a correction request.
Developer Phone Number
textEnter a direct phone number for the developer's office or principal contact in standard 10-digit format (e.g., '513-555-0100') — MSD reviewers use this number to reach the developer directly if the application requires clarification.
COMMON MISTAKE: Entering a general company switchboard number with no extension, or an outdated number, can cause MSD to be unable to reach the responsible party, stalling the review.
Developer Contact Person
textEnter the full name of the individual at the development company who is authorized to answer questions about this application — this should be a named person, not a role title like 'Project Manager.'
COMMON MISTAKE: Entering a job title (e.g., 'Site Manager') instead of a person's name means MSD has no individual to contact, which can delay responses to reviewer questions by days or weeks.
Engineer Name
textEnter the full legal name of the licensed Professional Engineer (PE) of record responsible for the water and sewer design plans — this must match the name on the engineer's Ohio PE license and the signed/sealed plan sheets submitted with the application.
COMMON MISTAKE: Entering the engineering firm's company name instead of the individual PE's name is a common rejection trigger, as MSD requires a named, licensed individual responsible for the design.
Engineer Street Address
textEnter the street address of the engineering firm's office where the PE of record is based — this should be the business address associated with the PE's professional license, not the project site address.
COMMON MISTAKE: Using the project site address instead of the engineer's office address creates a mismatch with professional license records and may raise questions about the PE's credentials.
Engineer City, State, ZIP
textEnter the city, two-letter state abbreviation, and ZIP code for the engineer's office address in the format 'Cincinnati, OH 45202' — this completes the engineer's contact address block and must be consistent with the address on file with the Ohio State Board of Registration for Professional Engineers.
COMMON MISTAKE: Entering an outdated office address that no longer matches the PE's current registration can prompt MSD to verify credentials, adding unnecessary delays to the review.
Engineer Phone Number
textEnter a direct phone number for the engineer of record — include an extension if the main office number routes through a switchboard — so MSD reviewers can reach the PE quickly with technical questions about the submitted plans.
COMMON MISTAKE: Providing only a firm-wide main number without an extension for the responsible PE means MSD cannot quickly reach the right person, which can slow technical review responses and delay approval.

Top 5 Water and Sewer Connection Permit Mistakes
1. Submitting an Incomplete or Inaccurate Site Plan
Based on ApronPrep's analysis of Water and Sewer Connection Permit applications in Cincinnati, the most frequent rejection trigger is a site plan that omits required details — specifically, the location of existing utility lines, property boundaries, and the proposed connection points to the city main. The Cincinnati Metropolitan Sewer District (MSD) and Greater Cincinnati Water Works (GCWW) require dimensioned drawings that clearly show the tap location, service line route, and distance from the right-of-way. Submitting a hand-sketched or non-to-scale diagram instead of a scaled engineering drawing will result in an outright rejection, adding 2–4 weeks to your timeline while you source a corrected plan.
2. Using the Wrong Permit Type for Your Connection Size
Cincinnati distinguishes between standard residential connections and larger commercial or grease-trap service connections, each requiring a different application form and fee schedule from GCWW or MSD. Restaurant owners frequently submit the residential tap permit when their service line exceeds 2 inches in diameter — a mismatch that triggers automatic rejection and requires refiling with the commercial application. Before submitting, confirm your required service line diameter with your licensed plumber and verify the correct form number directly on the GCWW or MSD portal; the wrong form adds at least 2–3 weeks to your approval timeline.
3. Failing to List a Licensed Ohio Plumbing Contractor
Cincinnati requires that all water and sewer connection work be performed by a contractor holding a valid Ohio plumbing license and registered with the City of Cincinnati's Division of Buildings and Inspections — the application must include the contractor's license number and registration on file. Applicants who list an unlicensed handyman or an out-of-state contractor, or who leave the contractor field blank intending to fill it in later, will have their application placed on hold rather than reviewed. Verify your contractor's Ohio license number at the Ohio Construction Industry Licensing Board (OCILB) lookup tool before submitting; an invalid or expired license number is one of the most common holds issued by city reviewers.

Gather Property and Site Documentation
Before submitting to Cincinnati Water Works (CWW), compile your property deed, survey, and site plan showing building footprint, proposed water/sewer line routes, and connection points. You'll also need your business license number, EIN, and proof of ownership or lease authorization. Most rejections at this stage occur when the site plan doesn't clearly mark existing utility lines — contact CWW's engineering division (513-591-6000) to request a utility locate if you don't have current utility marking.
Complete Water and Sewer Connection Application Form
Fill out the Cincinnati Water and Sewer Connection Permit application (available on CWW's online portal or in person at 1140 East 5th Street). The form requires 31 fields: property address, applicant contact information, connection type (new vs. repair/replacement), estimated water demand (in gallons per day), and sewer discharge estimate. ApronPrep auto-fills 18 of these fields from your business profile — you'll enter property-specific information manually. Ensure you've selected the correct connection type; applications with misidentified connection types add 1–2 weeks to processing.
Submit Application and Obtain Tracking Number
Submit your completed application, site plan, deed, and survey to Cincinnati Water Works either online through their applicant portal (cwwapplications.cincinnati-oh.gov) or in person at the customer service counter. Online submissions are processed within 1 business day; in-person submissions may take 2–3 days for data entry. You'll receive a tracking number immediately (online) or via email (in-person) — save this for all follow-up inquiries. Government filing fees start at $250 for standard connections; CWW's fee schedule is posted on their website.

See All RequirementsProcessing timelines vary depending on application completeness and inspection scheduling; per the Cincinnati Water Works website, you should expect the review and approval process to take several weeks from the date of application submission. To expedite approval, ensure all required documentation is submitted with your initial application and schedule your inspection promptly once notified by the permitting authority. Contact Cincinnati Water Works directly at (513) 591-6000 to confirm current processing times for your specific project.
Cincinnati does not charge a government filing fee for water and sewer connection permits; however, you may incur costs for required site surveys, engineering plans, or system upgrades mandated by the city's infrastructure standards. Before submitting your application, contact Cincinnati Water Works at (513) 591-6000 to request an itemized estimate of any associated project costs and connection fees. Not legal advice — verify all costs with Cincinnati Water Works to confirm current fee structure.
Water and sewer connection permits are location-specific and tied to the property's physical address; you cannot transfer an existing permit to a different address. If you relocate your restaurant, you must submit a new water and sewer connection permit application for the new location through Cincinnati Water Works. You may also need to obtain a new Building Permit and Certificate of Occupancy for the new facility before operations can begin.
Water and sewer connection permits do not require periodic renewal; once approved and the connection is active, your permit remains valid as long as you maintain compliance with Cincinnati's water quality and usage standards. However, if you modify your water or sewer system—such as increasing capacity or changing connection points—you must apply for a new or amended permit. Contact Cincinnati Water Works to confirm whether modifications to your existing infrastructure require a new application.
During the inspection, Cincinnati Water Works personnel will verify that your proposed water and sewer connections comply with city plumbing codes, that pipes meet size and material specifications, and that backflow prevention devices are installed if required. The inspector will also confirm proper grading and drainage to prevent contamination and ensure adequate water pressure and flow rates for your facility. If deficiencies are found, you'll receive a written notice detailing corrections needed before final approval; consider obtaining a Backflow Prevention Device Certification in advance to demonstrate compliance with anti-contamination requirements.
