How to Pay a Charleston Water System Bill Online

Charleston Water System uses a newer online customer portal through its payment processor. The portal can show your balance, accept payment, display past bills, enroll you in paperless billing and set up AutoPay.

1. Open the official payment options page.
   Start here: Charleston Water System Payment Options.
2. Use the new customer portal link.
   Charleston Water says usernames and passwords from the previous customer portal no longer work, so create or use your current portal access.
3. Review your account before paying.
   Check service address, balance, past bills and paperless billing preference before choosing a payment method.
4. Do not assume recurring payment is active.
   If you need monthly automatic payment, use AutoPay in the portal. A regular online payment may not create a recurring payment.
5. Save confirmation.
   Keep the confirmation number, receipt or screenshot until your account reflects the payment.

AutoPay and Paperless Billing for Charleston Water Customers

AutoPay is available through Charleston Water System’s payment processing partner. Once you register in the customer portal, you can select AutoPay so your bill is paid automatically on the due date.

Other Ways to Pay: Phone, In Person, Authorized Locations and Mail

If online payment is not the best choice, Charleston Water System also supports in-person service, phone payment, authorized payment locations and mail payment.

Start, Stop or Transfer Charleston Water/Sewer Service

If you are moving in or out, Charleston Water System says you can start or stop water/sewer service online, by phone or by visiting an office. Do not assume service starts or stops automatically because a lease or closing date changed.

1. Open the official Getting Service page.
   Start here: Charleston Water System Getting Service.
2. Choose start or stop service.
   Use the online request option if available, or call customer service at 843-727-6800.
3. Prepare your service details.
   Have service address, start/stop date, mailing address, account holder details and contact information ready.
4. Ask about final billing or deposits.
   If you are closing an account, ask how the final bill will be sent and what happens to any credit.
5. Save the confirmation.
   Keep email confirmation, request number or call notes in case billing continues after your move date.

High Charleston Water Bill Checklist Before You Call

A higher Charleston water bill can come from real usage, irrigation, a private service line leak, a running toilet, pool filling, sewer charges, delayed payment, or a bill-history change after moving.

Collect this before contacting Charleston Water

• Account number and service address.
• Current bill and previous two bills.
• Photos, plumber invoice or repair receipt if a leak was fixed.
• Dates when the leak started and when it was repaired.
• Notes about irrigation, guests, pool filling, pressure washing or construction.
• Payment confirmation if the issue is a missing or delayed payment.

Charleston Water Leak Adjustment: What Qualifies and What Does Not

Charleston Water System offers leak adjustments on sewer charges for qualifying leaks where the lost water did not go into the sewer system. Proof of repair is required.

1. Find and repair the leak first.
   Do not submit a request without repair details. Charleston Water requires proof of repair.
2. Open the official leak adjustment form.
   Use this form: Leak Adjustment Request.
3. Attach proof.
   Use plumber invoice, repair receipt, parts receipt or other repair documentation.
4. Explain where the water went.
   Qualifying adjustments focus on sewer charges when water did not enter the sewer system.
5. Keep paying normal charges if possible.
   Do not ignore the full bill while waiting for adjustment review. Call customer service if you need guidance.

Pool Fill Adjustment for Charleston Water Customers

Charleston Water System says customers who fill a pool may be eligible for an adjustment on sewer-related charges once every five years.

• Confirm whether your account is eligible before assuming the adjustment will apply.
• Keep pool fill date and approximate gallons used.
• Separate pool filling from irrigation, leaks or normal household usage.
• Call customer service if your bill is already past due or service is at risk.
