Payment channels

Pay City of Naperville Water and Wastewater Utility

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 Sebis; the City’s 2025 portal-launch materials state that the replacement eBill solution is owned by the City’s existing print-bill vendor, Sebis.. Never enter account credentials into a lookalike site reached through an unsolicited message.

Telephone payment

Phone IVR

A dedicated this detail was not publicly posted. The reviewed Naperville utility pages expose billing call-center and department numbers but not a dedicated automated payment number.

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

Naper Notify can send emergency and community information by phone, text, email, or app, but the reviewed utility eBill materials do not publish a text-to-pay keyword or SMS payment enrollment sequence.

Mail-in address

A dedicated this detail was not publicly posted. The reviewed Naperville eBill and rate pages do not expose the current utility remittance lockbox address. Customers should use the address printed on the monthly bill.

Counters, drop boxes, and office hours

Payment guidance

Choose the payment channel that fits your deadline

The safest payment path is the one published by City of Naperville Water and Wastewater Utility 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.
