What MPIUA is and where to pay
MPIUA stands for Maui Public Improvement Utilities Association. It is a water utility serving parts of Maui County in Hawaii. If you receive a water bill from MPIUA, you can pay online through their website at www.mpiua.com, by mail, by phone, or in person at their office.
The online payment portal is the fastest way to pay and gives you an immediate confirmation. You will need your account number, which appears on your bill, and a valid payment method — debit card, credit card, or bank account.
MPIUA bills are due by a specific date each month. If you miss the due date, late fees apply and your account may be flagged for service interruption. Knowing your due date and the payment methods available helps you avoid those charges.
Key Takeaways

- Your account number appears on your bill and is required to pay online or by phone.
- Late payments trigger fees and can lead to service interruption, so paying by the due date matters.
- You can set up automatic payments through the online portal to avoid missing future due dates.
Paying online through the MPIUA website
Go to www.mpiua.com and look for a "Pay My Bill" or "Online Payments" link on the homepage. Click it to enter the payment portal. You will be asked to enter your account number and either your service address or the amount of your bill to locate your account.
Once your account is found, you will see the amount due and the due date. You can then enter your payment method — debit card, credit card, or bank account information. The portal will ask for the name on the card or account, the card or account number, and the expiration date or routing information. Review the amount one more time before submitting.
After you submit, the portal will show a confirmation number. Write this down or take a screenshot. The payment usually posts to your account within one to two business days. If you do not see the payment reflected after that time, contact MPIUA with your confirmation number.
Mailing a check or money order
If you prefer to pay by mail, write a check or obtain a money order payable to MPIUA. Write your account number on the check or money order so the payment is matched to your account correctly.
Mail it to the address shown on your bill. MPIUA's office address is typically printed at the bottom of the bill or on the back. Allow at least one week for the mail to arrive and another few days for MPIUA to process and post the payment. If your due date is within a week, mailing is risky — paying online or by phone is safer.
Keep a copy of the check or the money order receipt for your records. If the payment does not appear on your account after two weeks, contact MPIUA with the check number or money order receipt.
Paying by phone or in person
You can call MPIUA to pay by phone using a debit card, credit card, or bank account. The phone number is on your bill. Have your account number and payment method ready when you call. A representative will walk you through the process and provide a confirmation number.
If you live near MPIUA's office, you can also pay in person during business hours. Bring your bill or account number and your payment method. The office staff will process the payment on the spot and give you a receipt.
Setting up automatic payments
The MPIUA online portal allows you to set up automatic payments so your bill is paid on the same day each month without you having to remember. Log into the portal, find the automatic payment or recurring payment option, and enter your payment method and the date you want the payment to go out each month.
Automatic payments reduce the risk of late fees because the payment goes out on schedule. You can change or cancel automatic payments at any time through the portal. If your bill amount changes month to month, you can set the automatic payment to match the amount due each billing cycle, or you can set a fixed amount and adjust it manually when needed.
What happens if you miss the due date
If your payment does not arrive by the due date shown on your bill, MPIUA will charge a late fee. The amount of the late fee varies and is stated in your bill or in MPIUA's billing terms. Late fees are added to your next bill.
If you continue to miss payments, MPIUA may send a notice of intent to shut off service. This notice gives you a window to pay the full amount owed, including late fees, before the water is disconnected. Once service is shut off, you will need to pay the full balance plus a reconnection fee to restore water.
If you are having trouble paying your bill, contact MPIUA directly to discuss your options. Some utilities offer payment plans or hardship programs, though availability varies by location and situation.
Finding your account number and bill information
Your account number is printed on your water bill, usually near the top or in a box labeled "Account Number" or "Service Account." It is a series of numbers unique to your property. You will need this number to pay online, by phone, or to contact MPIUA about your account.
Your bill also shows the amount due, the due date, the billing period, and the mailing address for payments. If you have lost your bill, you can call MPIUA to request a copy or to look up your account number by providing your service address.
