Official Casa Grande Utility Payment Resources

1. Guest Pay / One-Time Payment (No Full Registration Required – Fastest for Quick Payments)

The official Paymentus portal supports guest/one-time payments without creating a full online account.

How to pay as a guest:

  • Select your payment amount and choose bank account (eCheck/ACH) or credit/debit card (Visa, MasterCard, Discover, American Express).

Payments typically post within 1–2 business days. This method is ideal for urgent or one-time payments when you do not have (or want) a full registered account.
