Avoid surprises
Clarksville Water Bill Payment Fees in 2026
If the utility balance is $100
This is a simple illustration of the listed percentage fees—not a quote for a specific account. Always review the payment screen before authorizing a transaction.
A processing fee is tied to how you pay. A late penalty is tied to when the utility balance is paid. An overdue account can potentially have both.
24-hour payment access
Clarksville Gas & Water Kiosk Pay Sites
CGW lists multiple 24-hour kiosk locations around Clarksville. The machines can accept qualifying cash, check, debit and credit-card payments, post payments to the account in real time and print a confirmation receipt.
CGW specifically instructs kiosk users to have the full utility account number—including leading zeros—before starting.
Kiosk advantages
- 24-hour access
- Real-time posting
- Printed receipt
- English or Spanish interface
- FastPass barcode option
Kiosk limitations
- No coins
- No cash change dispensed
- Cannot establish new water service
- Cannot terminate utility service
- Cannot request a utility service work order
CGW replaced the former night-deposit drop box at 2215 Madison Street with the drive-up payment kiosk. Do not rely on older instructions telling you to use the former Madison Street night drop.
Past-due account
Clarksville Water Bill Late Fee, Shutoff & Payment Extension Rules
If the account balance is not paid in full by the due date shown on the bill, Clarksville’s current utility code provides for a ten-percent late-payment penalty.
Payment extension rules
CGW may agree to extend payment by 14 days from the customer’s scheduled last day to pay in order to avoid service interruption.
The current code permits up to two payment extensions per account in a twelve-month period, subject to the utility’s rules.
Customers on budget billing or with an outstanding returned item do not qualify under the current extension provision.
If you cannot pay the full amount, contact CGW at 931-645-7400 before the final payment deadline and ask what options are available on your specific account. An extension is not automatic.
Current reactivation charges listed in Clarksville’s fee schedule
After a nonpayment deactivation, the account may require payment of all amounts due plus applicable reactivation charges and any other deposit or account requirement that applies. Ask CGW for the exact restoration total before making a payment.
New customer or moving

Clarksville’s utility code also provides for a service fee when an existing customer moves to a new service location. Call CGW to coordinate the old-account termination and new-address activation rather than assuming the service automatically transfers.

Understand your water charge
Clarksville Water & Sewer Rates Used in 2026
Clarksville’s current municipal rate schedule continues to list the water rates effective July 1, 2024. A water bill generally combines a monthly meter/customer charge with usage measured in thousands of gallons. Sewer customers also have separate sewer usage charges.
Water usage rates
Monthly water customer charge by meter size
| Meter Size | Monthly Customer Charge |
|---|---|
| Up to ¾” | $9.00 |
| 1″ | $15.00 |
| 1½” | $30.00 |

| 3″ | $90.00 |

| 8″ | $465.00 |
| 10″ | $665.00 |
| 12″ or larger | $1,245.00 |
Residential/commercial sewer rate
The current residential/commercial sewer schedule states that the minimum monthly sewer bill is based on 2,000 gallons.
Illustrative 5,000-gallon residential bill components
Approx. $76.95
- Water usage: 5 × $4.45 = $22.25
- ¾” meter charge: $9.00
- Sewer usage: 5 × $8.14 = $40.70
- Environmental fee: $5.00
Approx. $124.20
- Water usage: 5 × $7.80 = $39.00
- ¾” meter charge: $9.00
- Sewer usage: 5 × $14.24 = $71.20
- Environmental fee: $5.00
Examples assume a ¾-inch meter, 5,000 gallons of measured use and CGW sewer service. They do not include natural gas, penalties, payment-provider fees, special services, adjustments or other account-specific items.
Always verify the current rate schedule when estimating a future bill.
Unexpected usage
High Clarksville Water Bill? Check Usage, Leaks & Adjustment Rules
Clarksville’s leak adjustment is primarily a sewer adjustment
Under the current city utility rules, CGW may adjust a customer’s sewer bill when water leaked through the customer’s piping and it can be determined that the leaked water did not enter the sewer system.
Current leak-adjustment rules include
Above-average use is generally calculated against the service location’s previous 12 months of monthly usage.
Up to two qualifying leak adjustments may be allowed per twelve-month period.
Each adjustment may include a maximum of two consecutive billing cycles.
The customer must provide documentation proving the leak has been repaired before the adjustment/plan is made.
CGW may approve an installment plan involving a leakage adjustment.
A water-leakage installment plan may not continue for more than six calendar months.
Save plumber invoices, repair receipts, photographs, dates of repair and any meter/usage information that helps show what happened. Better documentation makes it easier for CGW to determine whether the account meets the adjustment rules.
Pool-filling sewer adjustment
Clarksville’s code also provides a separate sewer-bill adjustment process for qualifying swimming-pool fills. It currently allows one qualifying adjustment per calendar year, potentially covering up to two consecutive billing cycles. CGW may request beginning/ending meter readings or the pool’s gallon capacity.
Water consumed normally, water entering the sewer system, irrigation use and unexplained usage may be treated differently. Contact CGW for an account-specific determination.
No water or low pressure
Clarksville Water Outage, Main Break & Low-Pressure Help
Water Outage & Utility Work Map
CGW maintains an official page for current and scheduled outages, low-pressure areas, road closures and water-system construction.
Low-pressure troubleshooting
CGW recommends removing and cleaning a clogged faucet aerator before assuming there is a system pressure problem.
CGW advises customers with hot-water-only pressure issues to consult a plumber.
Water softeners, filters, partially closed valves and a pressure-reducing valve can affect pressure throughout a property.
A sudden drop to almost no pressure can indicate a broken water line. Contact CGW promptly.
CGW’s pressure FAQ states that the property owner maintains the water pipe from the customer side of the meter yoke to the building and is responsible for pipes and fixtures within the building.

When something does not work
Clarksville Water Account & Payment Troubleshooting
| Problem | Try This First | Then Do This |
|---|---|---|
| Forgot username | Use the portal’s username-recovery option. | Call customer service if account verification fails. |
| Forgot password | Use Forgot Password on the official portal. | Avoid repeatedly creating new profiles. |
| Registration cannot find account | Recheck account number and billing ZIP. | Compare information with your latest CGW bill. |
| Need to pay but login fails | Use the official one-time payment route. | Save the payment confirmation. |
| Payment does not appear immediately | Check for a receipt or confirmation number. | Do not blindly resubmit the payment; contact CGW if needed. |
| Wrong account paid | Save proof of the transaction. | Contact CGW promptly and explain which account was intended. |
| Kiosk rejects account number | Enter the complete number including leading zeros. | Use another official payment method or call CGW. |
| Bill suddenly much higher | Compare usage history inside My Account. | Check for leaks and save repair documentation. |
Do not spend hours troubleshooting a username if another official same-day payment route is available. Use one-time payment, the billing line, a qualifying kiosk or a customer-service center as appropriate, then resolve the login issue separately.
