How to pay Harlingen WaterWorks bill online step by step
If you are paying online for the first time, start from the official HWWS website or the official customer web portal. This helps avoid unaffiliated payment websites and keeps your payment connected to the correct Harlingen WaterWorks account.
Open the official HWWS online payment portal
Go to the official customer web portal here: harlingen.epayub.com/Account/Login.
Choose login, account creation, or Quick Pay
Log in if you already have a portal account. Create an account if you want full online access. Use Quick Pay if you need a simple one-time payment without registration.
Keep your bill nearby
Have your account information ready before starting. If Quick Pay returns more than one result, carefully select the correct account before submitting payment.
Choose your payment method
The portal accepts online credit card, debit card, and one-time e-check payments. Quick Pay does not allow e-check, so use a portal account if you want that option.
Review processing fees
Third-party processing fees apply to one-time electronic payments. For card payments, the listed fee is the greater of $1.25 or 2.25%.
Save your confirmation
After payment, save the confirmation number or receipt. Keep it until the payment appears correctly on your HWWS account.
Important portal note: The Harlingen customer web portal says account access and payments are unavailable daily from 11:30 p.m. to 12:30 a.m. for maintenance. If your bill is urgent, avoid waiting until that window.

How Harlingen WaterWorks Bank Draft and autopay work
Bank Draft is the best official option if you want a free automatic-payment setup directly with HWWS. The payment options page says Bank Draft is a free service and customers can come into the office to register.
HWWS customer self-service information also references autopay through a completed credit/debit authorization form and bill pay through your bank or financial institution. Before relying on any automatic payment setup, verify that it is active and check the next bill or account history.
- Visit the HWWS office at 121 E. Harrison Ave. to ask about Bank Draft registration.
- Bring your account information and banking details required by HWWS.
- Ask when the first draft will begin.
- Keep paying normally until HWWS confirms the draft is active.
- Use your bank’s bill-pay system only after confirming delivery timing and account information.
- Check your next bill or portal payment history to confirm the draft processed correctly.
Practical advice: If you pay with a card every month, Bank Draft may be a better long-term option because HWWS lists it as a free service, while card payments include fees.
