Pay California American Water - Monterey District

Use the provider’s verified online, telephone, mail, or counter instructions. Check the final confirmation screen for the amount, processing date, and any transaction fee before submitting.

Primary online route

Use the official payment portal

The direct portal is the fastest route when it is available. The provider identifies its payment gateway as Paymentus (American Water MyWater payment platform). Never enter account credentials into a lookalike site reached through an unsolicited message.

Alternative channels

Mail, text, and in-person payment instructions

Pay by text

California American Water publishes electronic billing, outage, and usage communications but the reviewed Monterey customer pages do not document a separate text-to-pay keyword or enrollment sequence. Customers should enroll through MyWater or call customer service rather than assuming that an outage-alert text is a payment authorization.

Mail-in address

California American Water, PO Box 7150, Pasadena, CA 91109-7150

Counters, drop boxes, and office hours

The Monterey District customer-service location is listed at 511 Forest Lodge Road, Suite 100, Pacific Grove, CA 93950. The reviewed 2026 pages do not publish a reliable counter schedule or a complete list of authorized walk-in agents, so customers should confirm availability with 888-237-1333 before traveling. Mail, MyWater, Paymentus, and the automated telephone channel are the documented payment routes.

Accepted digital instruments

What you can use online

Visa, Mastercard, Discover, American Express, and electronic check/ACH through the MyWater/Paymentus channels; the reviewed 2026 Monterey page does not promise wallet support.

2026 transaction pricing

Convenience fees

California American Water states that its former $1.95 online credit/debit convenience fee has been eliminated. The reviewed page does not publish a separate 2026 e-check charge.

Fees can vary by payment type, channel, account class, and processor terms. The checkout screen is the final fee disclosure.

Payment guidance

Choose the payment channel that fits your deadline

The safest payment path is the one published by California American Water - Monterey District and matched to the account information on your bill. Online portals are convenient, but telephone, mail, counter, and drop-box options may follow different posting schedules and may use different fees.

For a routine payment, save the final confirmation page or IVR number and check when the transaction will post. For a same-day shut-off notice, do not assume that submitting a card payment automatically stops a field order; ask the provider what amount and confirmation are required.

Never send your account number, password, card details, or bank information to Water Ledger. Those details belong only on the provider’s verified payment channel or at an authorized counter.
