New Sewer and Water Service Areas in Gallatin: A Practical Guide

Water and sewer availability in the Gallatin service area is property-specific. Before buying land, subdividing property or submitting development plans, identify the water and wastewater providers and request written, parcel-specific availability confirmation. Gallatin Public Utilities handles many connections, but city limits, utility boundaries and actual connection availability are separate questions. Contact Gallatin Public Utilities at 615-451-5922 and confirm current fees, tap requirements, capacity and extension obligations before proceeding.

If you are buying land, building a home or planning a development in the Gallatin service area, do not assume that a nearby water or sewer line guarantees a connection. The first step is to identify the utility provider for the parcel and obtain current, property-specific confirmation of water and wastewater availability.

Gallatin’s official annexation materials include separate water-service-area and sewer-service-area map exhibits. The City’s April 2026 plan-of-service report also discusses locations where sewer lines were not installed in portions of west Gallatin, including the Long Hollow Pike and St. Blaise areas. Because service boundaries and infrastructure can differ by location, a parcel-level review is more reliable than relying only on city limits, a listing description or a map viewed without utility confirmation.

The short answer: service availability is parcel-specific

For a specific property, verify these four items before moving forward:

1. The responsible water provider. Gallatin Public Utilities provides water to Gallatin and also provides water to the Town of Westmoreland and the Castalian Springs/Bethpage Utility District. Other properties in the broader Gallatin area may fall within another provider’s service area.
2. The responsible wastewater provider. Water and sewer service areas are not necessarily identical, so confirm them separately.
3. Whether a main is physically available. A property may be near a line but still require an extension, easement, lift station, force main or other improvement.
4. Whether capacity and connection approval are available for the proposed use. A single-family home, subdivision, commercial project and industrial project may have different design, review and fee requirements.

A written availability letter or other official response is especially important for land purchases, subdivision plats and development plans. Sumner County’s minor-plat checklist calls for a water availability letter and a sewer availability letter when the property is served by public sewer or a STEP system.

Which agency or utility serves the property?

Gallatin Public Utilities

Gallatin Public Utilities provides water, sanitary sewer and natural gas service. Its administrative office is at 239 Hancock Street, Gallatin, TN 37066. The published customer-service phone number is 615-451-5922. The City’s Public Utilities directory lists regular office hours as Monday through Friday, 7:30 a.m. to 4:30 p.m., with drive-through hours from 8 a.m. to 4 p.m.

Gallatin Public Utilities’ water information page says the utility serves Gallatin and also provides water to Westmoreland and the Castalian Springs/Bethpage Utility District. It describes a water-distribution system that carries treated water to customers through mains and storage facilities.

The utility’s website includes separate pages for new residential service, small-commercial service and commercial or industrial service. New residential service requires an application, applicable connection and tap fees, identification and a building permit from the City of Gallatin Codes Department. Commercial and industrial projects may require plan review before a project-specific fee schedule is issued.

City of Gallatin Planning and Development

The City’s Planning and Zoning resources are useful for checking planning information, zoning and available GIS tools, but a planning map should not replace confirmation from the responsible utility. The City lists Planning at 132 W. Main Street, Gallatin, with a published phone number of 615-451-5796.

Development applications may also involve the City’s Building Codes Department, engineering review, site-plan requirements, floodplain rules and public-improvement obligations. City development-review materials state that certain site-plan and final master development plan applications must include surety for estimated site improvements, including public water and sewer line installation when applicable.

Sumner County Planning and Engineering

For property in unincorporated Sumner County or for county-reviewed plats, contact Sumner County Planning and Engineering about the applicable subdivision or plat process. County materials identify water and sewer availability letters among the supporting documents for minor-plat applications. The checklist lists the Sumner County Administration Building at 355 N. Belvedere Drive, Room 202, Gallatin, Tennessee 37066, and a published phone number of 615-451-6097.

How to verify water and sewer connection availability

Use this sequence for a home purchase, vacant lot or development site.

1. Gather the parcel information

Have the property address, parcel or tax-map information, owner information and a description of the proposed use ready. For development, include the number and type of proposed units, expected commercial use, fire-protection needs and anticipated construction schedule.

2. Check the jurisdiction and planning resources

Determine whether the property is inside Gallatin city limits, in the city’s planning region or in unincorporated Sumner County. City limits and utility service areas are related but are not interchangeable. Use the City’s official planning resources as a starting point, then confirm the result with the utility provider.

3. Contact the water provider

Ask whether the parcel is within the provider’s water service area, whether a water main is adjacent to the site, whether a meter can be installed for the proposed use and whether a main extension or other improvement is required.

4. Contact the wastewater provider separately

Ask the same questions about sanitary sewer. Specifically ask whether gravity sewer is available, whether a pump station or force main is required and whether the provider has identified limitations in the area.

Gallatin Public Utilities describes a wastewater collection system that includes gravity sewer, force mains, pumping stations and manholes. Those components mean that physical access and engineering requirements can vary from one property to another.

5. Request written confirmation

For a purchase, financing, subdivision or development review, request a written availability letter or equivalent written response. Keep the response with the property and project records, and ask how long the determination remains valid.

6. Confirm project-specific requirements

Ask for current tap fees, system-development charges, inspection charges, meter requirements, backflow or cross-connection requirements, easements, construction specifications and any required deposits or guarantees.

What new construction and development applicants should expect

Gallatin Public Utilities distinguishes between existing service and new service. New residential customers must submit the applicable service application, identification, connection and tap fees, and a City of Gallatin building permit. New small-commercial customers also need the applicable commercial application and building permit. Commercial and industrial projects must submit plans for review; after review and approval, the utility generates a project-specific fee schedule.

For a single residential or commercial lot, Gallatin municipal utility-extension regulations state that the owner or developer is responsible for qualifying costs associated with extending water or sanitary sewer mains and installing services to the lot. For residential or commercial subdivisions, the developer is responsible for infrastructure inside the development, including water and sanitary sewer facilities and, when required, pump stations and force-main sewers.

That means “service available” can have more than one practical meaning. A utility may serve the general area, while the individual project still needs engineering, construction, approvals and payment for the infrastructure required to reach and serve the site.

Current Gallatin Public Utilities connection and usage charges

Gallatin Public Utilities publishes separate fees, tap charges, system-development charges and monthly rates. The following examples appear in the utility’s published schedules and should be rechecked before a financial decision:

Charge category — Published amount or basis

Water connection fee — $30 inside or outside city limits; commercial connection fee listed separately at $100

Water inspection — $50 per tap

Sanitary sewer inspection — $50 per tap

Residential water tap and installation — $750 for a 5/8-inch by 3/4-inch meter; larger meters have higher charges

Single-family sewer tap and installation — $750 inside city limits; $1,500 outside city limits

Water system-development charge — Based on meter size; the published schedule lists $2,300 for a 0.75-inch meter

Sanitary sewer system-development charge — Based on meter size; the published schedule lists $2,500 for a 0.75-inch meter

The utility’s published fees page states that system-development charges were effective July 1, 2025, while its rates page lists water and wastewater rates effective July 1, 2026. A project may also incur extension, engineering, construction, fire-protection, special-assessment or other charges not represented by a basic residential tap fee.

What to ask before buying land or starting a project

Ask the utility and planning office:

• Which entity provides water to this parcel?
• Which entity provides sanitary sewer service?
• Is the property inside the provider’s current service boundary?
• Is a water main and sewer main adjacent to the property?
• Is there confirmed capacity for the proposed number of homes or the proposed commercial use?
• Will the project require a main extension, pump station, force main, easement or right-of-way?
• Who pays for design, permits, inspections, construction and restoration?
• Which tap, meter, system-development and inspection fees apply?
• Is a building permit, site plan, final development plan, plat or availability letter required first?
• How long will the written availability determination remain current?
• Are there floodplain, topographic or access issues that could affect the design?

Do not rely solely on a seller, builder, listing agent or previous owner for utility information. Their statements may describe an earlier project, a different parcel or a planned extension rather than currently available service.

Official next steps and contact information

For a Gallatin-area property, begin with Gallatin Public Utilities at 615-451-5922 and ask for property-specific water and sewer availability. The utility’s published administrative-office address is 239 Hancock Street, Gallatin, TN 37066. The utility’s contact page also lists a service center at 249 Hancock Street and separate water-treatment and wastewater-treatment plant numbers.

For planning or development-review questions, contact Gallatin Planning at 615-451-5796. For county plat questions, Sumner County Planning and Engineering lists 615-451-6097.

If the property is part of an annexation, review the City’s current annexation notifications and plan-of-service materials as background. The City’s annexation page currently lists pending and approved annexation resolutions and an April 2026 plan-of-service report. Annexation, zoning and utility connection are separate decisions, and one does not automatically guarantee the others.

MyGallatin recommendation: Before making an offer on undeveloped land or budgeting a new project, make utility availability a written due-diligence item with a defined response deadline. That step can reveal extension costs, service-area limitations and approval requirements before they become closing or construction problems.
