Payment channels

Pay City of Boulder Utilities – Water and Utility Billing

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 InvoiceCloud, identified in the city’s Customer Billing Portal instructions and terms. Never enter account credentials into a lookalike site reached through an unsolicited message.

Telephone payment

Phone IVR

844-581-6021. Boulder’s Water Utilities page describes 24/7 phone payment by credit card, debit card, or ACH/bank account. Utility Billing customer-service questions and service-start/stop requests use 303-441-3260; after-hours emergencies use 303-441-3200.

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

Boulder provides text-message bill payment and automatic reminders through the Customer Billing Portal. The customer must register or log in at water.bouldercolorado.gov, open the View/Pay Bill area, and enable the text-payment/reminder option shown for the account. The public page does not publish a keyword or short code; enrollment is portal-based and the live account interface controls the phone-verification steps and payment authorization.

Mail-in address

City of Boulder Utility Billing Office, P.O. Box 734774, Dallas, TX 75373-4774. Write the account number on the check memo line, include the payment stub in the return envelope, and do not mail cash. Boulder uses a third-party vendor to securely process paper checks.

Counters, drop boxes, and office hours

Customers may deposit a bill payment in the Utility Billing drop box on the west side of the Municipal Building at 1777 Broadway, Boulder, CO 80302. Utility Billing office hours are Monday–Wednesday 9 a.m.–4 p.m., Thursday 9 a.m.–3 p.m., and Friday 9 a.m.–4 p.m.; the billing phone is 303-441-3260. The current official page emphasizes the drop box and portal rather than a staffed cashier counter. For planned maintenance shutoff help, call 303-441-3260 during business hours; emergency water issues use 303-441-3200.

Accepted digital instruments

What you can use online

The Customer Billing Portal accepts credit card, debit card, checking or savings account ACH, Google Pay, and Apple Pay. Customers can make a one-time payment without registering, create a full account, schedule payments, set up autopay, and view bills and usage. The 24/7 phone channel accepts credit/debit card or ACH/bank-account payment. Text-message payment and reminders are available after portal enrollment.

2026 transaction pricing

Convenience fees

The current Boulder public billing page does not state a separate online card, mobile-wallet, ACH, or phone convenience-fee amount. Customers should review the InvoiceCloud checkout disclosure before submitting a payment. The city’s published utility charges do identify operational service fees, including the $58 reconnect and $128 after-hours reconnect, but those are not payment-processor convenience fees.

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 Boulder Utilities – Water 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.
