How to pay a Gallatin water and sewer bill

Gallatin Public Utilities lists several payment methods. Customers can pay through the utility’s online payment portal, by phone at 833-373-8740, by mail, through automatic bank draft, at the payment kiosk or in person. The utility also lists Gallatin City Hall and the Gallatin Department of Electricity as additional payment locations..

Online payment

The utility’s online account system allows customers to pay a bill, view the account balance and review billing and payment history. The utility says customers need the customer number and PIN printed on the utility bill to access the account.

Gallatin Public Utilities also offers a customer dashboard for usage monitoring and customized alerts. That dashboard is separate from the payment function, so customers should follow the utility’s current enrollment instructions rather than assuming one login controls every feature.

Phone, mail and in-person payments

Customers may use the automated phone-payment line at 833-373-8740. For mailed payments, the utility instructs customers to send the payment and billing stub to Gallatin Public Utilities, 239 Hancock St., Gallatin, TN 37066. The utility’s customer-service page also lists payment by bank draft and in-person payment at the Hancock Street office.

If you pay in person, check the current office and drive-through hours before leaving. The city directory lists the office as open weekdays from 7:30 a.m. to 4:30 p.m., with drive-through service from 8 a.m. to 4 p.m.

Starting, transferring or ending water service

Gallatin Public Utilities provides online forms for common account tasks, including residential and commercial service applications, landlord applications, service transfers, scheduled disconnects, account-information updates, automatic payments, electronic billing and payment arrangements.

For a new residential account, start with the utility’s residential application or contact customer service at 615-451-5922. Commercial and industrial customers should use the commercial application and ask the utility what additional documentation or approvals apply to the property.

A property owner, renter or business owner should have the service address and account information available before contacting the department. The utility may require additional information based on the customer type, ownership arrangement and whether the property already has a meter or active service. Because requirements can change, confirm the current application checklist directly with Gallatin Public Utilities before scheduling a connection.

Landlords can use the utility’s landlord application and related authorization forms. Customers moving within the service area should use the transfer-service process rather than opening a completely unrelated account, if the utility confirms that the move qualifies as a transfer.

How to report a water or sewer problem

For an urgent problem involving Gallatin’s public water or wastewater system, call 615-451-5922. The City of Gallatin lists that number as both the Public Utilities phone and the after-hours emergency phone.

When calling, describe the location, the type of problem and whether water is entering a building, a roadway is affected, sewage is backing up or a nearby public facility is at risk. If there is an immediate threat to life or serious property damage, call 911 first.

Water leaks and leak adjustments

A leak on private property may be the customer’s responsibility, while a leak involving a public main, meter or utility-owned equipment may require Public Utilities to inspect the site. Do not assume that a high bill automatically qualifies for an adjustment.

Gallatin Public Utilities publishes a Leak Adjustment Form among its customer-service forms. Customers should document the apparent leak, repair date and repair invoice or other supporting information before submitting a request. The utility—not a third-party guide—determines whether an adjustment applies.

Sewer and stormwater are not the same service

Sanitary wastewater flows to the wastewater system. Stormwater runoff is managed through separate city programs involving Engineering and Public Works. Gallatin also maintains an illicit-discharge reporting process for suspected pollution entering the storm-drain system. That process is different from reporting a sanitary-sewer backup or a water-main break.

Gallatin water and sewer rates and connection fees

Water and sewer charges can depend on factors such as the service category and whether the property is inside or outside Gallatin’s corporate limits. City agenda materials published in 2026 describe separate water and sewer rates, connection charges and sanitary-sewer tap fees, but the current enforceable schedule should be confirmed with Gallatin Public Utilities before a customer relies on a specific amount.

This is especially important for property owners, builders and businesses planning a new connection. Ask the utility or the responsible city department to confirm:

• Whether the property is inside the city limits or in an area served outside the limits.
• Whether the request is for a new water connection, sewer tap, meter, transfer or reconnection.
• Whether a separate inspection, engineering, development or permitting fee applies.
• Which party is responsible for work in the right of way and on private property.
• Whether the fee schedule has changed since the application or ordinance was issued.

Do not use an old utility bill, an older audit or an online estimate as a substitute for the current official fee schedule.

Gallatin water quality reports

Gallatin Public Utilities publishes consumer water-quality information through the City of Gallatin and its utility website. The city’s 2025 Water Quality Report announcement says the report describes monitoring results and compliance with federal and state standards. The announcement states that treatment requirements were met, no lead or copper action levels were exceeded and monitoring continues for emerging contaminants including PFAS.

The latest report identified in the city’s current news materials is the 2025 Water Quality Report. Readers should use the utility’s official report rather than relying on generalized claims about local water quality. If you have a question about water taste, discoloration, pressure or a possible advisory, contact Public Utilities directly at 615-451-5922.
