Signing Up

I don't have my most recent bill. How do I sign up?

Call Customer Service at 843-727-6800. You can either use the automated system to get your account information, or speak to a Customer Service Representative (M-F, 8-5).

I tried registering for an account, but the system won't let me. Why?

Either you have already registered for online access to your Charleston Water System account, or you are entering incorrect information.

If you think you or a family member is already registered for an online account but you don't know the username or password, e-mail CustomerService@charlestoncpw.com or call (843) 727-6800 for assistance.

Your Account

Can I register to pay a family members bill using my name and bank account information?

Yes. All you need to sign up for online bill payment is the account number and the current bill amount.

Can I remove an account from my profile?


I removed my account from my customer profile and now I'm not able to sign in. Why?

If you remove all accounts from your profile, your customer profile will be permanently deleted. To access your account, you have to re-register for online bill payment and input your account information.

How do I update my e-mail address in my profile?

Click the Profile Settings link.

I have several accounts. Can I pay each bill with a different bank account?

Yes. You can, or pay each with a credit card.

Username and Password

I forgot my password. How do I reset it?

Click on the "Forget Your Password?" link on the sign in page.

I forgot my username. What should I do?

Click on the "Forget Your Username?" link on the sign in page.

Can I change my username?

Yes, if you have your last bill handy. Sign in to your online account and delete your profile by going to "Profile Settings" and click "Remove Account". Click "Submit", then re-register the account number with a new username.

Making Payments

When will my payment be posted?

If you make a payment online before 5 pm EST on a business day, it will be posted the same day.

Payments made after 5 pm, on weekends, or on holidays will be posted the next business day after 5 pm.

For example, if you make a payment on Saturday, the payment will post to the account on Monday after 5 pm. If Monday is a holiday, then it will post Tuesday after 5 pm.

Can I change a payment once I submit it?

If you made a payment using your bank account, you have until 5 pm EST on the date you made the payment to cancel it. Payments made with a credit card cannot be changed or deleted.

Need assistance, call Customer Service at (843) 727-6800.

Do I have to pay the full amount due on my account?

No, but your payment may not exceed the amount due.

The system won't let me select a payment date. Why?

If your payment is past due, you will not be able to select a future date.

Can I request a payment extension online?

No, please call 843-727-6800 and select option 1 on the main menu to request an extension in our automated system.

How do I find out my past due balance?

Click on Billing History. If you have a past due balance it will be listed on your bill.

I thought I signed up for automatic recurring payments, but my bill wasn't paid. What happened?

When you register for online access to your account, you must manually make a payment with a credit card, debit card or bank account each month. The system does not allow automatic, recurring payments.

If you want to have your bill amount automatically drafted we offer Auto Draft from your bank account only. Complete the required information on our Auto Draft Request Form and click submit.

If you are currently signed up in Auto Draft, you can change/modify or delete your bank account information. Complete the required information on our Auto Draft Request Form and click submit.

Is my credit card information safe when I save it to my profile?

Yes. Using encryption technology, your card number is transmitted to and stored with a 3rd party card processer and all subsequent transactions are executed with a non-identifying secure code. Charleston Water System at no time stores the card number in our environment.

Can I make multiple payments in one day?

If you need to make another payment, call (843) 727-6800 to pay by phone.

Can I overpay so that I have a credit?
