Payment channels

Pay Grand Strand Water & Sewer Authority (GSWSA)

Use the provider’s verified online, telephone, mail, or counter instructions. Check the final confirmation screen for the amount, processing date, and any transaction fee before submitting.

Primary online route

Use the official payment portal

The direct portal is the fastest route when it is available. The provider identifies its payment gateway as GSWSA eBilling portal; the reviewed official portal and bill-pay page do not identify a separate processing vendor.. Never enter account credentials into a lookalike site reached through an unsolicited message.

Telephone payment

Phone IVR

843-443-8334 for the automated or telephone bill-payment route identified on GSWSA’s bill-pay page; customer-service numbers are 843-443-8202 and 843-765-4539.

Have your account number and payment instrument ready. Follow the provider’s recorded prompts and retain the confirmation number.

Alternative channels

Mail, text, and in-person payment instructions

Pay by text

GSWSA offers account text-message notifications rather than a documented text-to-pay command. Customers submit the account number and mobile number on the official SMS enrollment page, receive a verification code by text, and enter that code to validate the number. Standard carrier messaging rates apply; the reviewed page does not authorize payment by replying to a keyword.

Mail-in address

Billing remittances: Grand Strand Water & Sewer Authority, P.O. Box 2308, Conway, SC 29528. The general mailing address is P.O. Box 2368, Conway, SC 29528; customers should use the billing address printed on the current statement.

Counters, drop boxes, and office hours

Cash payments are accepted at the Conway Administrative Office, 166 Jackson Bluff Road, Conway, SC 29526; the Marion Office, 510 Supply Road, Marion, SC 29571; and the Little River Office, 2375 Highway 111, Little River, SC 29566. GSWSA publishes cash hours of 8:00 a.m.-4:00 p.m. Monday-Friday. Customers may also use drop boxes, drive-through service, and authorized bank locations: Conway National Bank in Horry County, Anderson Brothers Bank in Horry and Marion Counties, and Coastal Carolina National Bank in Horry County. Confirm check, money-order, and office processing details before travel.

Accepted digital instruments

What you can use online

GSWSA accepts bank draft, eCheck, and Visa, Mastercard, Discover, or American Express credit cards through the online account or telephone payment channels. The official home page also identifies e-check and automatic bank draft as direct payment methods; external bill-payment sites are not affiliated with GSWSA.

2026 transaction pricing

Convenience fees

A dedicated this detail was not publicly posted. The current publicly accessible GSWSA bill-pay and rate pages list payment methods but do not expose a universal 2026 online card, eCheck, or portal convenience-fee amount. Any fee shown in the eBilling checkout should control the transaction.

Fees can vary by payment type, channel, account class, and processor terms. The checkout screen is the final fee disclosure.

Payment guidance

Choose the payment channel that fits your deadline

The safest payment path is the one published by Grand Strand Water & Sewer Authority (GSWSA) and matched to the account information on your bill. Online portals are convenient, but telephone, mail, counter, and drop-box options may follow different posting schedules and may use different fees.

For a routine payment, save the final confirmation page or IVR number and check when the transaction will post. For a same-day shut-off notice, do not assume that submitting a card payment automatically stops a field order; ask the provider what amount and confirmation are required.

Never send your account number, password, card details, or bank information to Water Ledger. Those details belong only on the provider’s verified payment channel or at an authorized counter.
