2026 transaction pricing

Convenience fees

Recurring electronic funds transfer is explicitly free and carries no additional service charge. The current Longmont pages reviewed do not state a 2026 card convenience-fee amount for one-time online credit/debit payments; customers should review the portal’s transaction screen before submitting a card payment.

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 City of Longmont Water Utilities and Utility Billing 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.
