Alternative channels
Mail, text, and in-person payment instructions
Pay by text
Riverside Public Utilities does not publish a keyword-based text-to-pay program or an SMS short code on its 2026 customer-service pages. Customers can register for the Riverside bill-pay portal, use the 311 mobile application, or enroll in Direct Pay by completing the City form, listing the check writer as a responsible utility-account party, and attaching a voided check. The City’s Riverside Alert notification service is separate from bill payment and should not be treated as a payment enrollment channel.
Mail-in address
Riverside Public Utilities, 3900 Main Street, Riverside, CA 92522-0144. Customers should enclose the remittance payable to Riverside Public Utilities in the envelope provided with the paper bill and include the account information or payment coupon so the utility can apply the payment to the correct water-and-city-services account.
Counters, drop boxes, and office hours
Payments and account assistance are available at the Downtown Customer Service Center, 3901 Orange Street, Riverside, CA 92501, Monday–Friday 9:00 a.m.–5:00 p.m. and Saturday 9:00 a.m.–12:30 p.m.; and at the Customer Resource Center, 3025 Madison Street, Riverside, CA 92504, Monday–Friday 9:00 a.m.–5:00 p.m., closed weekends. The official bill page states that customers may pay in person at these centers, but it does not enumerate a separate drop-box schedule or every payment instrument accepted at the counter. Customers should bring the bill and use the payment methods displayed by the cashier; the City’s online and Direct Pay materials confirm card and bank-account payment channels.
