Payment channels

Pay Central Arkansas Water

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 Paymentus. Never enter account credentials into a lookalike site reached through an unsolicited message.

Telephone payment

Phone IVR

CAW publishes a fee-free checking-account Paymentus automated line at 1-833-245-1947. Its helpful-service page also identifies 1-855-742-0309, option 2, for one-time automated checking-account payments; customers should use the number shown on the current bill because CAW manages multiple billing partners and districts.

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

CAW offers emergency and service text notifications and asks customers to confirm SMS enrollment in their online account profile. The reviewed current payment pages do not publish a separate text-to-pay keyword or short code; text alerts are primarily for service status, while Paymentus handles account payment and SMS communication terms.

Mail-in address

Utility Billing Services, P.O. Box 8100, Little Rock, AR 72203-8100. CAW separately lists P.O. Box 1789, Little Rock, AR 72203-1789 for general correspondence and warns customers not to mail payments to that correspondence address.

Counters, drop boxes, and office hours

CAW’s customer-service and billing center is associated with 221 East Capitol Avenue, Little Rock, Arkansas 72203. The current service materials publish customer-service call-center hours of 7:30 a.m.–5:00 p.m. Monday–Thursday and 8:00 a.m.–4:30 p.m. Friday; the reviewed current pages do not expose a complete list of walk-in cashier addresses, kiosk locations, or drop-box hours. Customers should confirm the current in-person payment site before visiting.

Accepted digital instruments

What you can use online

Paymentus supports checking-account/e-check payments and electronic payment methods available through its live portal. CAW specifically advertises fee-free checking-account payments through the automated system; the reviewed current public pages do not enumerate card brands, mobile wallets, or the exact card processor fee, so customers should use the live checkout disclosure.

2026 transaction pricing

Convenience fees

Fee-free checking-account payment is explicitly available through CAW’s Paymentus automated system. The reviewed current public pages do not state an exact 2026 online credit/debit flat fee or percentage surcharge; any card or third-party charge should be shown by Paymentus before authorization.

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 Central Arkansas Water 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.
