Convenience fees

No credit-card processing fee for eligible single-family residential accounts, according to BWS payment instructions. The reviewed BWS pages do not publish a separate 2026 e-check or digital-wallet convenience surcharge; multi-family and non-residential card-payment eligibility is more limited and should be confirmed with BWS.

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 Honolulu Board of Water Supply (BWS), City and County of Honolulu 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.
