Payment channels

Pay City of San Marcos SMTX Utilities

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 Customer Connect; the 2026 City procurement identifies Paymentus, NorthStar Utilities Solutions, MeterSense, Online Utility Exchange, and Infosend as integrated systems, but does not identify one exclusive portal vendor.. 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

Customer Connect supports email or SMS text notifications for new bills and payment confirmations and offers water-use threshold alerts. The City does not publish a text-to-pay keyword; customers enroll at connect.sanmarcostx.gov and manage notification preferences.

Mail-in address

A dedicated this detail was not publicly posted. The reviewed San Marcos bill materials publish online, telephone, City-location, night-drop, and authorized-store payment options but do not expose a single current mail remittance address in the accessible text.

Counters, drop boxes, and office hours

Utility Customer Service lobbies/drive-throughs are open Monday through Friday, 8:00 a.m. to 5:00 p.m. at the Utility Billing Office, 1040 Highway 123. City locations and night drop include the Municipal Building at 630 E. Hopkins and SMTX Utilities at 1040 Highway 123. In-office payments accept cash, check, money order, cashier's check, Mastercard, Visa, and Discover; H-E-B Business Center payments process the next business day.

Accepted digital instruments

What you can use online

Customer Connect supports one-time and recurring payment by e-check, Visa, Mastercard, Discover, and checking/savings account. The City also offers electronic billing and automated telephone payments at 512-393-8333. Recurring payments draft on the due date.

2026 transaction pricing

Convenience fees

A dedicated this detail was not publicly posted. The reviewed San Marcos Customer Connect and rate pages do not expose a current 2026 online card/e-check convenience-fee amount.

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 City of San Marcos SMTX Utilities 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.
