Mail, text, and in-person payment instructions
Pay by text
IRWD’s current payment pages do not publish a dedicated text-to-pay keyword or short-code enrollment path. Customers can use the Paymentus portal, one-time phone payment, bank bill pay, or in-person/mail methods. IRWD does offer IRWD Alert and usage-monitoring tools, but those are notification or water-efficiency services rather than a published SMS payment enrollment program.
Mail-in address
Irvine Ranch Water District, P.O. Box 51403, Los Angeles, CA 90051-5703 for the current payment-options page; the District notes that its mailing address changed January 23, 2026 and instructs customers to use the billing stub/courtesy envelope and include the 10-digit account number in the Invoice Number field so the payment posts correctly.
Counters, drop boxes, and office hours
IRWD Headquarters, 15600 Sand Canyon Ave., Irvine, CA 92618, accepts walk-in or drive-through check payments Monday through Thursday, 8:00 a.m.–5:00 p.m., and on alternate Fridays; the parking-lot drop box is available after hours and weekends and posts on the next business day. The current table identifies check-only in-person/drop-box payment with no convenience fee. The current IRWD pages do not list a staffed cash counter or a complete third-party payment-center directory, although a separate cash-pay guide describes barcode cash payments at participating retail stores and warns that a convenience fee may apply.
