Mail, text, and in-person payment instructions
Pay by text
Fontana Water Company does not publish a keyword-based text-to-pay enrollment flow. Customers can enroll in AutoPay by submitting the company application with a voided check, or use the InvoiceCloud online account for one-time and recurring credit-card, debit-card, or eCheck payments. The official pages do not identify an SMS short code, opt-in keyword, or text-payment portal.
Mail-in address
Fontana Water Company, P.O. Box 5970, El Monte, CA 91734-1970. Customers should send the detachable remittance portion of the bill and payment through this lockbox, not to the physical Fontana office. The company warns customers to use its authorized payment channels and not the unaffiliated Doxo service.
Counters, drop boxes, and office hours
Fontana Water Company accepts in-person payment at its customer-service offices; the published billing page specifically lists Fontana Water Company, 15966 Arrow Route, Fontana, CA 92335, with a front-entrance drop box. The Fontana office is open Monday–Thursday 7:00 a.m.–5:30 p.m.; the company’s service page also lists regular customer-service hours and alternating Friday availability, so customers should confirm the Friday schedule at (909) 822-2201. The company says its three customer-service offices accept cash, checks, cashier’s checks, and money orders, with checks payable to Fontana Water Company. The company publishes other office locations through its customer-service materials but does not expose a complete current address-and-hours table in the reviewed page.
