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.

The direct portal is the fastest route when it is available. The provider identifies its payment gateway as My Account by Nexus Water Group (vendor platform details not otherwise identified). 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

Suburban Water Systems does not publish a universal SMS keyword or text-to-pay enrollment code for La Mirada. Customers can use My Account alerts and reminders after registering with the account number, or follow any account-specific invitation sent by the utility. Treat unsolicited payment texts as potential scams; independently open account.mywater.us or call 1-800-203-5430 to validate a notice.

Mail-in address

Suburban Water Systems Payment Center, PO Box 6105, Covina, CA 91722-5105. Write the 10-digit account number on the check or money order, include the payment stub, do not mail cash, and allow enough postal time for posting.

Counters, drop boxes, and office hours

The published administrative address is 1325 N. Grand Avenue, Suite 100, Covina, CA 91724-4044. Customer-service hours are Monday through Friday, 8:00 a.m. to 4:30 p.m. Pacific, but the website does not represent the Covina office as a public walk-in cashier. Walmart MoneyCenter or Customer Service Desk can process same-day cash or debit-card Walmart Bill Pay when the customer provides the utility name and account number; participating retail locations set their own hours and may charge fees. The back of the bill may list authorized offices or payment locations, so confirm current counter, drop-box, holiday, and retail arrangements before visiting.

Accepted digital instruments

What you can use online

My Account accepts one-time or recurring AMEX, Discover, Mastercard, and Visa credit/debit payments, bank-account/eCheck payments, and digital wallets including Venmo, PayPal, Apple Pay, and Google Pay. Bank Auto Pay from checking or savings is advertised as free. Business customers cannot use Visa or Mastercard through the portal but can pay online by check. Cash or debit is available through Walmart Bill Pay and other non-digital channels.

2026 transaction pricing

Convenience fees

Suburban's current payment page does not state a routine utility-imposed online convenience fee for portal eCheck or card payment; the final confirmation screen controls any disclosed charge. Bank Auto Pay is described as free. Unaffiliated services such as Doxo or Mint may charge their own fees and are not endorsed by Suburban; retail payment locations can also add fees.

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 Suburban Water Systems - La Mirada System (Whittier/La Mirada Service Area) 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.
