Credit Card Fees

Rainbow Water is recovering the merchant costs for accepting credit cards and debit cards with a new 2.95% card processing fee. Implementing a separate fee protects customers paying by cash, check, or bank transfer from absorbing credit card transaction costs. This fee is charged by the payment processor, and Rainbow Water does not receive the fee payments. This fee covers card processing costs and affects payments made via: auto-pay, in-person, online, and by phone.

• Fee-Free Alternatives: Avoid processing fees by paying via cash or check made out to the Rainbow Municipal Water District. Cash payments accepted in person at the Rainbow Water office.
• Online Fee-Free Payments: Enroll in ACH payment by calling Customer Service at 760-728-1178.
