Where to send your Charlotte Mecklenburg water payment
Charlotte Mecklenburg Utilities (CMU) accepts water bill payments through three main channels: online through their website, by phone, or by mail. The online portal at charlottenc.gov/utilities lets you pay immediately with a bank account or debit card. You can also call 311 (or 704-336-5500 from outside Charlotte) to pay by phone with a representative, though this method may include a small fee depending on your payment type.
If you prefer to mail your payment, send it to the address printed on your bill — typically Charlotte Mecklenburg Utilities, P.O. Box 34269, Charlotte, NC 28234. Include your account number on the check or money order. Mail payments take 7 to 10 business days to process, so plan ahead if your bill is due soon.
Auto-pay is available through the CMU website and removes the need to remember due dates. You can set it up to withdraw from your bank account on a date you choose each month. This option is free and can be cancelled anytime.

Reading your Charlotte Mecklenburg water bill
Your CMU bill shows your account number, service address, billing period, and the amount due by the due date listed near the top. The bill breaks down charges into water usage (measured in hundred cubic feet, or HCF), sewer service, stormwater fee, and any taxes. One HCF equals about 748 gallons.
The usage section shows your current month's consumption compared to the same month last year. If your usage has jumped significantly, check for running toilets, dripping faucets, or leaks in visible pipes. A toilet leak alone can add hundreds of gallons to your monthly bill without you noticing.
CMU bills are issued monthly, and the due date is typically 20 days after the bill date. Late fees apply if payment is not received by the due date. If you cannot pay the full amount by the due date, contact CMU before the deadline to discuss a payment plan.
What to do if your bill seems too high
Start by comparing your current usage to the previous three months shown on your bill. A sudden spike often points to a leak. Check under sinks, around the water heater, and in the basement or crawlspace for wet spots or dripping sounds. Toilet leaks are the most common culprit — add food coloring to the tank and see if it seeps into the bowl without flushing.
If you cannot find a visible leak, contact CMU at 704-336-5500 and request a meter reading verification. A representative can confirm whether your meter is working correctly or whether the high reading reflects actual usage. This service is free and takes a few days.
If CMU confirms a leak on their side of the meter (the main line from the street to your home), they may adjust your bill. Leaks on your property are your responsibility to repair, but some water providers offer rebates for fixing leaks quickly — ask CMU whether a rebate program is available.
Setting up a payment plan if you fall behind
If you cannot pay your full bill by the due date, contact CMU immediately at 704-336-5500 or visit a payment office in person. Do not wait until after the due date — CMU is more likely to work with you if you reach out before a late fee is applied.
CMU offers payment arrangements for customers who are behind on their bills. The terms depend on how much you owe and your payment history. A representative will discuss a schedule you can meet, typically spread over two to four months. You must make payments on time during the arrangement or risk service disconnection.
If you are struggling to pay due to a hardship — job loss, medical emergency, or reduced income — ask about low-income assistance programs. CMU partners with community organizations to help may have access to households. The representative can direct you to these resources or provide contact information for local aid organizations.
Avoiding late fees and service disconnection
Late fees are added to your account if payment is not received by the due date shown on your bill. The fee amount varies but is typically a percentage of your bill or a flat amount — check your bill or CMU's website for the current fee structure. Late fees compound if you miss multiple payments.
If your account reaches a certain past-due amount (usually around $100 to $150, though this varies), CMU will send a disconnection notice. This notice gives you a deadline — typically 10 to 15 days — to pay the full past-due balance or set up a payment plan. If you do not respond, water service will be shut off at the meter.
Reconnection after a shutoff requires paying the full past-due balance plus a reconnection fee, which can be $100 or more. To avoid this, respond to any disconnection notice immediately, even if you can only pay part of what you owe. Calling 704-336-5500 to set up a payment plan before the deadline is faster than trying to reconnect later.
Understanding CMU's billing and service area
Charlotte Mecklenburg Utilities serves the City of Charlotte and parts of unincorporated Mecklenburg County. If you live within this service area, CMU is your water and sewer provider. Some areas outside Charlotte — such as parts of Cornelius, Huntersville, or Pineville — may have their own water systems, so confirm your provider before looking for payment options.
CMU's service territory includes roughly 900,000 people across the Charlotte metro area. If you are unsure whether CMU serves your address, enter your street address on their website or call 311 to confirm. Your bill will also show "Charlotte Mecklenburg Utilities" or "CMU" at the top if they are your provider.
Billing and payment policies are set by CMU and reviewed by the City of Charlotte's utility commission. If you have a dispute about a charge or believe an error was made, you can file a complaint with CMU's customer service department. They investigate billing disputes and may adjust your account if an error is found.
Frequently Asked Questions
Can I pay my CMU bill with a credit card?
Yes, you can pay with a debit card or credit card through the online portal at charlottenc.gov/utilities. Phone payments also accept cards, though a processing fee may apply depending on the payment method. Check the website or call 311 for current fee information.
What happens if I move and still owe a balance?
Contact CMU before you move to request a final meter reading and bill. You remain responsible for any balance owed, even after you leave. CMU can mail your final bill to your new address, and you can pay it online, by phone, or by mail using the account number from your last bill.
How do I dispute a charge on my water bill?
Call CMU at 704-336-5500 and explain the charge you believe is incorrect. A representative will review your account and meter history. If an error is found, your bill will be adjusted. If you disagree with their finding, you can request a formal review through CMU's customer service department.
Is there a way to reduce my water bill?
Fix leaks as soon as you find them — a running toilet can waste 200 gallons per day. Install low-flow showerheads and faucet aerators, which reduce usage without noticeably changing water pressure. Water your lawn early in the morning to reduce evaporation. CMU's website has a water conservation guide with more tips.
What if I cannot afford my water bill?
Contact CMU at 704-336-5500 before your bill is due to discuss a payment plan or ask about low-income assistance programs. CMU works with local nonprofits to help households in hardship. You can also call 211 (a free referral service) to find emergency assistance programs in Mecklenburg County.
