Where to pay your Charleston water bill
Charleston Water System accepts payments through three main channels: online at their website, by phone, or by mail. The online portal is the fastest option and lets you see your balance and payment history immediately. You can set up a one-time payment or enroll in automatic monthly payments so you never miss a due date.
To pay online, go to the Charleston Water System customer portal at charlestonwater.com. You will need your account number, which appears on your bill. The site accepts payments by bank account (ACH transfer) or debit card. Bank transfers typically process within one business day and have no fee. Debit card payments process immediately but may carry a small convenience fee depending on the payment processor.
If you prefer to pay by phone, call Charleston Water System's customer service line. Have your account number and payment method ready. Mailed payments should be sent to the address printed on your bill, and you should allow 7 to 10 business days for the payment to reach and post to your account.

Setting up automatic payments to avoid late fees
Automatic payments are the simplest way to ensure your bill is paid on time every month. Once you enroll, Charleston Water System will deduct the amount due from your bank account on a set date each billing cycle. You can change or cancel automatic payments at any time through the online portal.
To set up automatic payments, log into your account on charlestonwater.com, navigate to the payment section, and select the automatic payment option. You will enter your bank account information and choose whether you want to pay the full bill amount or a fixed amount each month. Most households choose to pay the full bill so they do not carry a balance.
If your bill amount varies significantly month to month, you can still use automatic payments but set them to a fixed amount and adjust it seasonally. For example, many people pay a higher amount in summer when water use increases, then lower it in winter.
Understanding your bill due date and late payment consequences
Charleston Water bills are typically due 20 days after the bill date. The due date is clearly marked on your bill statement. If payment is not received by that date, Charleston Water System will charge a late fee. The amount of the late fee varies but is usually a percentage of your bill or a flat fee—check your bill or call customer service for the exact amount in your area.
If your bill remains unpaid for 30 to 45 days past the due date, Charleston Water System may issue a notice of intent to disconnect service. This notice gives you a window to pay the overdue amount plus any late fees and reconnection costs before water service is shut off. Reconnection fees can range from $50 to $150 or more, depending on the reason for disconnection and whether a technician must visit your home.
If you cannot pay your full bill by the due date, contact Charleston Water System immediately to discuss payment arrangements. Many utilities offer short-term extensions or payment plans for customers facing temporary hardship. The sooner you reach out, the more options you may have.
How to read your Charleston water bill
Your Charleston water bill shows several key pieces of information. At the top, you will see your account number, service address, and billing period (the dates the bill covers). Below that is your current charges section, which breaks down water usage, sewer charges, and any other fees.
The usage section shows how many gallons of water you consumed during the billing period. Charleston Water System measures usage in units called "hundred cubic feet" (HCF), where one HCF equals about 748 gallons. Your rate per HCF is listed separately, and the total usage charge is calculated by multiplying your usage by the rate.
Sewer charges are usually a percentage of your water charge and appear as a separate line item. Some bills also include stormwater fees, which fund drainage and flood management. At the bottom of your bill, you will see the total amount due and the due date. If you have a balance from a previous month, it will be shown as a separate line.
Payment options if you cannot pay in full
If you are unable to pay your full bill by the due date, contact Charleston Water System's customer service before the due date passes. Explaining your situation early gives you the best chance of working out a solution. The utility may offer a short-term extension (usually 10 to 15 days) or a payment plan that spreads your bill over two or more months.
Payment plans typically require you to pay a portion of the bill immediately and the remainder over the next one to three billing cycles. You will need to make these payments on time to keep the plan in place. If you miss a payment under a plan, the utility may cancel the arrangement and proceed with late fees or disconnection.
Some customers also explore whether they may have access to for bill assistance programs run by local nonprofits or government agencies. These programs are separate from Charleston Water System itself and have their own income limits and application processes. Your local 211 service (dial 211 or visit 211.org) can tell you which programs serve your area.
Checking your account balance and payment history
The Charleston Water System online portal shows your current balance, recent payments, and billing history. Log in with your account number and password to view this information at any time. This is useful if you want to confirm that a payment has posted or check how much you owe before making another payment.
Your payment history shows the date each payment was received and the amount. If you pay by mail, allow 7 to 10 business days for the payment to appear in your history. Online and phone payments typically show within one business day. If a payment you made does not appear after the expected time, contact customer service with your confirmation number or receipt.
You can also set up bill notifications through the portal so you receive an email or text message when your bill is ready to view or when a payment is due. This helps prevent accidental late payments and keeps you aware of your usage patterns.
Frequently Asked Questions
Can I pay my Charleston water bill with a credit card?
The Charleston Water System portal accepts debit cards but typically does not accept credit cards directly. Some third-party payment processors may allow credit card payments, but they usually charge a higher convenience fee. Check the payment options on charlestonwater.com to see what is currently available.
What happens if I pay my bill late?
Late fees are added to your account if payment is not received by the due date. If the bill remains unpaid for 30 to 45 days, you will receive a disconnection notice. After that, water service can be shut off. Reconnection requires paying the overdue balance, late fees, and a reconnection fee.
How do I change my billing address or account information?
Log into your account on the Charleston Water System portal and look for account settings or profile information. You can update your mailing address, phone number, and email there. If you cannot find the option online, call customer service and they will make the change for you.
Can I set up automatic payments if I rent?
Yes. Renters can set up automatic payments just like homeowners. Your name must be on the account with Charleston Water System. If your landlord pays the water bill, you will not have an account and cannot set up payments yourself.
What should I do if I think my bill is too high?
First, compare your current bill to previous months to see if usage has actually increased. A spike can indicate a leak. Check for running toilets, dripping faucets, or water pooling in your yard. If you suspect a leak, contact Charleston Water System to request a meter check. If usage looks normal but the rate seems wrong, call customer service to review your account.
