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
- My Smart Water Connect / ACWD customer portal. The portal.acwd.org system provides account login, one-time payment, usage analysis, paperless billing, automatic payment, leak alerts, and mobile-app access.
- Phone payment number
- (510) 668-4200. ACWD’s automated phone payment system accepts Visa, Mastercard, Discover, debit card, and electronic check without an additional payment fee; customer-service representatives are available Monday–Friday 8:00 a.m.–5:00 p.m.
- Pay-by-text
- Register or log in at https://portal.acwd.org/portal/, open Billing, select Text to Pay, complete the enrollment steps, and confirm the enrollment email. ACWD publishes no separate keyword or short code because the text-payment feature is activated within the My Smart Water Connect account; the portal then sends payment-related notifications to the enrolled mobile contact.
- Mail-in payment address
- Alameda County Water District, PO BOX 101837, Pasadena, CA 91189-1837. Mail a check with the payment coupon in the envelope supplied with the bimonthly bill; ACWD recommends mailing at least seven business days before the due date because payment must be received and applied by the due date.
- In-person payment
- ACWD Headquarters, 43885 S. Grimmer Boulevard, Fremont, CA 94538, accepts in-person payments Monday–Friday 9:00 a.m.–4:00 p.m.; the District’s business office hours are 8:00 a.m.–5:00 p.m. Counter payment types are cash, check, money order, Visa, Mastercard, and Discover. A night drop box to the right of the front doors accepts checks and money orders after hours; do not place cash in it. Customer-service telephone assistance is available at (510) 668-4200, and there are no published third-party retail payment locations.
- Digital payment methods
- The ACWD portal and automated phone system accept bank-account/electronic-check payments, Visa, Mastercard, Discover, debit card, and ATM-card payment; the District also supports automatic payments and paperless billing. ACWD does not publish Apple Pay, Google Pay, PayPal, Venmo, or a separate digital-wallet option for water bills. Pay-by-Text is enrolled through the customer portal.
- Online convenience fees
- No additional online or telephone payment fee is charged for the listed bank-account, Visa, Mastercard, Discover, debit-card, or ATM-card payment methods. ACWD’s payment page specifically states that one-time online payments and automatic payments have no additional fee; the District’s $5 late fee and field charges are delinquency charges, not payment-processor surcharges.
