Frequently Asked Questions

How quickly will my service to an existing residence be turned on?
Please allow one business day's notice before you'd like the water turned on. Please check to ensure all your faucets and other fixtures are in the off position, and plan to have someone at your home when we schedule to activate your service. This will prevent water damage in the event that any faucets are in the on position.

If no one is present, we may not be able to activate service. Please be aware there is a fee for a return visit.

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.

Closing a Commercial Account with a Fire Service
Commercial accounts that have a serparate fire service line must provide written authorization from the property owner, insurer, and fire marshall before Charleston Water System will close the account. Click here to download the authorization form (PDF fillable form).

This policy is intended to protect the property in the event of a fire and to protect Charleston Water System from liability. If written authorization is not provided, we will continue to bill the account until a new party requests water service at the location.
