Lexington customers: do not mix these bills

Why Many Lexington Customers Receive Two Separate Utility Bills

Most Lexington customers receive a Kentucky American Water bill for water service and a separate LEXserv bill for city services such as sanitary sewer, landfill and the water quality management fee. Paying one does not automatically pay the other.

Kentucky American Water

Use MyWater, the payment phone line, kiosk or other Kentucky American Water payment methods for the water account.

Customer Service: 1-800-678-6301
SEPARATE BILL

LEXserv

LEXserv bills Lexington sanitary sewer, landfill and water quality charges. Its billing can run two to three weeks behind the Kentucky American Water billing period.

LEXserv: 859-280-8047 or 888-987-8111
Moving in Lexington: When you start Kentucky American Water service, KAW sends the account information to LEXserv, so most customers do not need to create the LEXserv account separately. When KAW service is stopped or transferred, that information is also forwarded to LEXserv.

How to Pay a Kentucky American Water Bill Online

Choose MyWater or guest pay. Use MyWater when you want account history, Auto Pay, paperless billing and usage tools. Use the official one-time payment processor when you do not want to register.
Match the account before entering payment details. Confirm that the provider is Kentucky American Water and match the account number, service address and amount due to the current bill.
Choose the payment method. In MyWater, a one-time bank payment is listed as free. Card payments carry a $1.95 fee. Guest-payment fees are shown by the processor.
Review the payment date. If the account is close to a shutoff deadline, verify when the payment will post and call Customer Service if timing is critical.

Past-due decision path

Late Fees, Shutoff Notice and Reconnection Rules

The current Kentucky American Water tariff applies a 5% late fee to charges paid after the due date, with specified exclusions such as previously assessed penalties and certain third-party charges. A qualifying low-income assistance pledge or notice can also affect the late fee for that bill.

Missed due date Review the newest MyWater balance and any 5% late fee.
Call before shutoff Ask about a payment arrangement or assistance while service is still active.
Written notice The tariff requires at least 10 days written notice for nonpayment shutoff.
Service disconnected Arrears plus the applicable reconnection charge must be paid before restoration.
Company restores service Do not turn the meter back on yourself.
Past-due rule Current tariff detail What the customer should do
Late fee 5% on eligible unpaid charges after the due date Check the newest balance before paying.
Minimum notice At least 10 days written notice before shutoff for nonpayment or rule violation Do not ignore the notice; call before the cutoff date.
Original-bill timing Shutoff cannot occur less than 20 days after the mailing date of the original bill under the tariff rule Use the notice and bill dates to understand the timeline.
Medical postponement A qualifying written certificate from a physician, registered nurse or public health officer can postpone residential discontinuance for 30 days beyond the termination date Contact Customer Service immediately for the required process.
Reconnection charge $56 when service was discontinued for nonpayment or a rule violation Confirm total arrears and fees before expecting restoration.
Returned payment charge $12 for a returned check or electronic funds transfer under the currently posted tariff Replace the failed payment promptly and confirm whether the account is still at risk of late action.
Do not reconnect the meter yourself: The tariff says a customer whose water service has been turned off may not turn it back on or have another person do so. Restoration must be handled by Kentucky American Water.
Act before the due-date problem grows

Payment Arrangements, Budget Billing and H2O Help to Others

Payment arrangement Kentucky American Water says an arrangement may require at least 25% of the bill within 48 hours, the remaining balance on an agreed schedule, and all future bills paid when due.
Arrangement eligibility The official page says customers who broke a similar agreement during the prior 12 months are not eligible for another arrangement under that rule.
Budget Billing Eligible residential customers can ask about a fixed monthly payment plan based on anticipated annual billing.
H2O income rule The current official H2O page still references household gross income at or below 225% of the 2025 Federal Poverty Income Guidelines.
H2O account rules The page also lists at least $25 paid toward the water bill in the prior 180 days and an outstanding balance of at least $50.
H2O grant amount The current maximum grant is $250, generally one grant per calendar year while funds are available. Community Action Council administers the program.
Verify H2O eligibility before applying: Because the Kentucky American Water page still references the 2025 federal poverty guidelines in 2026, call Community Action Council at 859-233-4600 or the appropriate local Community Action agency to confirm the currently applied income limit and fund availability.

High bill troubleshooting

What to Check When Your Kentucky American Water Bill Jumps

Compare usage, not just the dollar total. Open MyWater and compare the current period with earlier months. Note guests, irrigation, pool filling, appliance changes or other unusual water use.
Run a two-hour meter test. Turn off water-using fixtures and appliances, note the meter reading, wait two hours without using water, and check the meter again. Movement can indicate a leak.
Check toilets and fixtures. A toilet flapper, faucet, water heater or irrigation problem can create high usage, but these indoor fixture leaks do not qualify as a hidden service-line leak under the special adjustment tariff.
Look for an underground service-line leak. Wet ground, unexplained meter movement or a plumber finding a leak between the meter and the premises can point to the type of leak covered by the adjustment rule.
Keep repair evidence. Save the plumber’s statement, receipts or material list showing the underground leak was repaired.
Ask for a meter test when the readings still look wrong. The tariff allows a customer to request a written meter test no more than once every 12 months. A test cost may be charged, but it is returned if the meter is found more than 2% wrong to the customer’s prejudice.
Hidden service-line leak rules

When a Kentucky American Water Leak Adjustment Can Apply

Can qualify A hidden underground leak in the customer service line between the meter and the premises. Residential and commercial customers are included under the current rule.
Does not qualify under this tariff Leaks from toilets, water heaters, faucets and similar fixtures are specifically excluded from the hidden underground service-line definition.
Adjustment rule What it means
Repair proof Provide a plumber’s statement or a list of materials showing the service-line leak was repaired.
Usage comparison After repair verification, the utility compares the leak-period usage with the average of the prior six billing periods, or a reasonable estimate when six periods are unavailable.
Excess-use rate Usage determined to result from the qualifying service-line leak is billed at 25% of the applicable tariff rate.
Frequency limit Only two adjustments are allowed during the lifetime of a water service line.
Billing-period limit Each adjustment may cover no more than two billing periods.
Third request Before a third adjustment can be considered, the entire service line from the meter box to the premises must be replaced.
Submit the hidden-leak request after repair: The official Kentucky American Water page says the completed form and repair proof can be faxed to 859-268-6315, emailed to kawc_-_customeradvocacy@amwater.com, or mailed to Customer Advocacy, 2300 Richmond Road, Lexington, KY 40502. Keep a copy of the form and repair evidence.
Lexington sewer bill: If a leak also raised a separate LEXserv sewer bill, review LEXserv’s sewer-user-fee adjustment process separately. Kentucky American Water and LEXserv are different billing systems.
Current 2026 rate-case status

Do Not Treat Proposed 2026 Kentucky American Water Rates as Final

Kentucky American Water filed Kentucky Public Service Commission Case 2026-00094 seeking a rate adjustment. On May 27, 2026, the PSC suspended the proposed rates for six months through December 13, 2026, with a formal hearing scheduled for October 13-15, 2026.

For a current bill: Use the rates and charges actually shown on the live account and the currently effective tariff. Do not calculate a payment from proposed rate-case figures that have not become effective.

Review Kentucky American Water’s current rates page or check PSC Case 2026-00094 for the live case status.
