How do I apply for service?
Applying for service as a Charleston Water System customer is easier than ever before! You may apply for service over the phone by calling 727-6800 during our business hours of 8:00 a.m. to 5:00 p.m., Monday through Friday. All information for commercial services can be taken over the phone; however Charleston Water System requires most commercial accounts to identify one individual within the company who will be responsible for water and sewer debts. You may also apply for service at any of our office locations.

What information do I need when applying for service?
Charleston Water System requires most commercial accounts to identify one individual within the company who will sign a form agreeing to assume responsibility for all water and sewer debts at the address. Charleston Water System will accept service over the phone; however, the agreement must be returned to our office within 14 days from the responsibility date.

• The name of the company, the name of the commercial co-signer, and his/her social security number.
• The date you would like to water service to begin.
• The address of the property location to receive service.
• Your mailing address (if it is different that the service address)
• A daytime and evening phone number.

How quickly will my service to an existing location be turned on?
Please allow at least one day's notice for activation of water service. To ensure that all faucets are secured and that there are no leaks, someone should be at the property when we come to turn on your water. This protects your property from any possible water damages that could occur if faucets are turned on when service is established. Please be aware that there may be an additional charge for a return visit if on the scheduled day Charleston Water System's serviceperson is unable to turn the water on due to an indication that water fixtures are on at the property.

What are the fees charged for establishing service to an existing location?
An origination fee is charged on all new accounts to cover the expense of establishing the account. This fee will be added to your first bill for the location and must be paid within 21 days. The origination fee is non-transferable and non-refundable. Click here to view our list of fees.

Commercial accounts may have additional fees. Contact our Customer Service Department for further details.

For commmercial accounts with a fire service..
Please note that Charleston Water System requires written authorization from the property owner, insurer, and fire marshall before disconnecting public water service to a commercial facility with a fire service line. If this authorization is not provided, Charleston Water will continue to bill the account until another party requests water service. Click here for more information.
