Payment research for this provider
The compiled notes distinguish confirmed channels from details the public material did not expose. Fields containing only an unavailable-information marker are grouped in the research record below.
- Payment platform
- InvoiceCloud for fee-free billing and payment, integrated with the City’s WaterSmart customer-usage portal powered by VertexOne
- Phone payment number
- (510) 583-4636; the City publishes this as the phone payment line and states that customers can pay by debit or credit card without a fee. A separate IVR vendor or limited-hours schedule is not published; billing/service assistance is (510) 583-4600.
- Pay-by-text
- No separate text-to-pay enrollment workflow or keyword is published for 2026. The WaterSmart portal does support customer alerts by text, email, or phone, including leak and usage notifications, but the City’s payment instructions do not identify a text message that authorizes a payment or provides a text-to-pay keyword. Customers should use the authenticated portal, phone line, kiosk, or cashier instead of treating an alert as a payment request.
- Mail-in payment address
- Hayward Water System, PO Box 6004, Hayward, CA 94540. The City accepts checks by mail and no cash; postmarks are not accepted, so payment must arrive and be processed before the due date.
- In-person payment
- The Revenue/Cashier office is on the first floor of City Hall, 777 B Street, Hayward, CA 94541, and accepts in-person utility payments Monday through Thursday, 8:00 a.m.–5:00 p.m., excluding holidays; it is closed Fridays. The exterior self-service kiosk facing the City Hall plaza is available 24/7, and a second kiosk near the first-floor guard station is available on weekdays during public hours. Kiosks support English and Spanish, issue receipts, accept cash, checks, and credit/debit cards without processing charges, and credit excess cash to the account rather than making change. Customers may also pay cash at participating 7-Eleven, CVS, Walgreens, and other CheckFreePay locations found through the City’s payment-center locator; the account number or bill barcode is required. The City’s cashier handles starting/stopping service and leak-rebate applications as well as utility billing.
- Digital payment methods
- The InvoiceCloud/WaterSmart portal accepts e-check/ACH, American Express, Visa, Mastercard, Discover, PayPal, PayPal Credit, Venmo, Apple Pay, and Google Pay. The City also accepts debit or credit card payments by phone at (510) 583-4636 and supports autopay and paperless billing in the portal.
- Online convenience fees
- No convenience fee is charged for the listed online payment methods in 2026. The City specifically describes the portal, phone card payment, and self-service kiosks as fee-free; this replaced the former $3.95 card convenience fee.
