Water and Sewer Connection Permit in Boston, Massachusetts (2026)
Without a Water and Sewer Connection Permit from the Boston Water and Sewer Commission, your restaurant cannot legally connect to the city's water and sewer infrastructure — meaning you cannot operate. The Water and Sewer Connection Permit (also called a water service permit or sewer hookup authorization) is issued by the Boston Water and Sewer Commission and authorizes your specific connection points and capacity allocation.

Why You Need a Water and Sewer Connection Permit
In Boston, operating a commercial kitchen requires a formal connection to the city's potable water and sanitary sewer systems, regulated by the Boston Water and Sewer Commission (BWSC) and the Boston Public Works Department. The legal basis is found in the Boston Sewer Use Regulations and related road and sidewalk ordinances, which require a permit for any new service tap, lateral connection, or alteration to existing water and sewer infrastructure on public property. This permit process is also linked to compliance with local grease discharge limits and water conservation requirements for commercial establishments. Without this permit on file, the city has no record of your establishment's approved infrastructure, leaving your business legally exposed.
Failure to secure a proper permit before opening or making changes leads to severe and costly consequences. Based on analyses of BWSC enforcement actions, typical penalties for operating without this permit include:
- Service Disconnection: The BWSC can physically shut off your water and sewer service, forcing an immediate and indefinite closure.
- Daily Fines: Violations incur escalating penalties, starting with substantial one-time fines and potentially moving to daily accruals until the issue is resolved.
- Required Remediation: You may be forced to halt construction or operations and remove any unpermitted work, paying all costs for tearing up sidewalks/streets and reinstalling connections correctly.
- Permit & Project Revocation: Unpermitted work can jeopardize related permits (like your building or occupancy permit) and violate your lease covenants or insurance policy terms for property improvements.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2026, the Boston Water and Sewer Commission has integrated its application portal with the city's broader permitting system, requiring digital submissions for all new connection projects.
Who Needs a Water and Sewer Connection Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required for any new or modified water/sewer service connection for a commercial kitchen, per Boston Water and Sewer Commission (BWSC) Rules & Regulations § 3.02. |
| Bar / Nightclub | Required | Required for new or modified sanitary sewer connections to handle restroom facilities and potential bar/glass wash sinks, as mandated by BWSC's plumbing code provisions. |
| Food Truck | Not Required | Typically connects to a commissary's permitted infrastructure; a separate connection permit for the mobile unit is not required from BWSC for temporary operations on public ways. |
| Coffee Shop / Café | Required | Required due to the installation of plumbing fixtures for espresso machines, sinks, and restrooms, triggering a need for a formal connection under Boston plumbing codes. |

23 of 28 auto-filledBusiness Legal Name
textEnter the exact legal name of the business entity (e.g., 'Boston Bistro LLC') as it appears on your Articles of Organization filed with the Massachusetts Secretary of the Commonwealth.
COMMON MISTAKE: Using a DBA/trade name instead of the registered legal entity name, which will cause the application to be rejected.
Business Type
textEnter the business structure, such as 'Limited Liability Company (LLC)', 'Corporation', 'Sole Proprietorship', or 'Partnership', as defined in your state registration documents.
COMMON MISTAKE: Entering 'Restaurant' or 'Food Service' instead of the legal entity type, which does not match official records.
Business Contact Phone
textProvide a direct, working phone number for the primary business contact (e.g., owner or project manager) where Boston Water and Sewer Commission (BWSC) inspectors can reach you during business hours.
COMMON MISTAKE: Providing a disconnected number or a personal cell without voicemail, which can delay inspections and permit approval.
Business Contact Email
textEnter a professional email address that is monitored daily, as the BWSC will send all official correspondence, fee invoices, and inspection notices to this address.
COMMON MISTAKE: Using a generic or personal email that filters important messages to spam, causing missed deadlines.
Property Address
textEnter the complete street address of the property where the new water/sewer connections will be made, using the official format from the City of Boston Assessing Department parcel data.
COMMON MISTAKE: Omitting the unit/suite number or using an informal address (e.g., 'near the park'), which fails to match the parcel ID in the city's system.
Property Ownership Status
textState whether you are the 'Owner' of the property or a 'Tenant'. If you are a tenant, you must attach a lease authorization letter from the property owner.
COMMON MISTAKE: A tenant checking 'Owner' or failing to provide the required owner authorization, which invalidates the application.
Lease Authorization Letter
textIf you are a tenant, you must attach a signed letter from the property owner authorizing the water/sewer connection work. The letter must be on company letterhead and reference the specific property address.
COMMON MISTAKE: Submitting an unsigned letter, a letter without the property owner's contact information, or a generic lease agreement instead of a specific authorization for utility work.
Site Plan Available
checkboxCheck this box only if you have a detailed, scaled site plan ready to submit. The plan must show the exact location of proposed water and sewer taps relative to property lines, existing structures, and public mains.
COMMON MISTAKE: Checking the box without having a professional, stamped site plan, which will lead to an immediate 'incomplete application' rejection from BWSC engineering review.
Detailed Site Plan
textIf you checked 'Site Plan Available', enter the file name of your uploaded site plan PDF. The plan must be drawn to scale by a licensed professional and clearly mark all proposed connection points.
COMMON MISTAKE: Uploading a hand-drawn sketch or a plan without a professional seal, which does not meet BWSC engineering standards and causes a 2–3 week delay for resubmission.
Building Plans Available
checkboxCheck this box if you have approved building plans from the Boston Inspectional Services Department (ISD). BWSC cross-references your connection application with ISD permits for plumbing fixture counts.
COMMON MISTAKE: Checking this box before ISD has issued building permits, which creates a data mismatch and will halt your BWSC application until ISD approval is verified.

Top 5 Water and Sewer Connection Permit Mistakes
1. Submitting Without the Exact-Page Site Plan
The Boston Water and Sewer Commission (BWSC) requires a detailed, to-scale site plan (minimum 1"=20') showing the precise location of the proposed service connection from the main to the building. Submitting a basic zoning map or conceptual drawing triggers an immediate rejection for insufficient information. Pull the exact-page site plan from your architectural or engineering drawings to avoid a 2–3 week delay.
2. Using an Outdated Legal Property Description
Entering the property's common address or an informal description (e.g., 'corner of Main and First') is insufficient. The application must match the formal legal description from your deed or the City of Boston's Assessing Online database. Applications with mismatched legal descriptions are stalled until corrected, adding 1–2 weeks to processing. Verify the parcel ID and full legal description before applying.
3. Incorrectly Calculating the Connection Fee
The connection fee is based on your water meter size, not a flat rate. Selecting a standard 5/8" meter when your commercial kitchen requires a 1" or larger meter results in an underpayment and application hold. BWSC will not process the permit until the correct fee is paid. Confirm your required meter size with your plumber or engineer and cross-reference the BWSC Fee Schedule before submitting payment.

Timeline: Varies
Step 1: Contact Boston Water and Sewer Commission (BWSC) Business Customer Services at 617-989-7000 to request Water and Sewer Connection Permit application materials
Call BWSC during business hours (Monday–Friday, 8 AM–4:30 PM) to confirm you need a Water and Sewer Connection Permit and request the application packet. Have your restaurant's street address and property owner contact information ready. BWSC will direct you to their online portal or mail application materials — most restaurants receive packets within 2–3 business days.
Step 2: Prepare site plan documentation showing property layout, existing infrastructure, and proposed connection points per BWSC Site Plan Requirements
Hire a licensed surveyor or engineer to prepare a site plan at 1:40 scale showing the building footprint, lot lines, existing utility lines (water main, sewer main, storm drains), and your proposed connection points — this is the most common cause of application delays. The plan must include the distance from the property line to connection points and note whether you're connecting to combined or separate sewer systems. Coordinate with your plumber to finalize connection specifications before submitting.
Step 3: Complete application form with building details, intended water usage volume, and grease trap/discharge specifications (critical for restaurant operations)
Fill out the BWSC connection application form (typically 8–12 fields) including your restaurant's square footage, estimated daily water usage (in gallons), type of grease trap or interceptor you'll install, and intended use (food service). Boston requires restaurants to specify grease trap capacity and maintenance plan — underestimating water usage or omitting grease trap details is the #1 rejection reason for food service applicants. Attach copies of your food service license or application to verify your use type.

See All RequirementsProcessing timelines vary depending on the complexity of your project and the completeness of your application, per the Boston Water and Sewer Commission (BWSC) application guide. Simple connections with no complications typically proceed faster than those requiring design review or easement coordination. Contact the BWSC directly at (617) 989-6800 or visit their website to confirm the current estimated timeline for your specific project scope.
Government filing fees for water and sewer connection permits in Boston range from $617 to $7,000, as posted on the BWSC fee schedule, depending on the scope of work, property size, and whether both water and sewer services are being installed or upgraded. Additional costs may apply for required inspections, plan reviews, or engineering certifications—such as a Backflow Prevention Device Certification if your system requires one. Verify the exact fee for your project by contacting the BWSC or requesting a formal estimate. Not legal advice — confirm current fees with the authority.
No, water and sewer connection permits are location-specific and cannot be transferred to a new address. If you are relocating your restaurant, you will need to apply for a new water and sewer connection permit for your new location, submit updated site plans, and obtain approval from the Boston Water and Sewer Commission. Your existing permit will terminate at your former address unless you formally request a disconnection or conversion.
Water and sewer connection permits in Boston do not require periodic renewal—they are issued once for a specific property and remain active for the life of that connection, per BWSC standards. However, if you modify, expand, or upgrade your water or sewer infrastructure, you must obtain a new or amended permit and may need to resubmit design documentation and pass inspection. Contact the BWSC to determine if your planned changes trigger a new permit requirement.
The BWSC inspection verifies that your water and sewer lines are installed according to approved plans, meet all code requirements (including proper slope, materials, and connections), and are free of leaks or structural defects. If your installation includes backflow prevention equipment, inspectors will also verify compliance with state and local codes—you may need a separate Backflow Prevention Device Certification before final approval. If deficiencies are found, you will receive a written correction notice with a deadline to remedy the issues before final sign-off.
