Where to Pay Your Miami Water Bill

Miami-Dade County Department of Regulatory and Economic Resources (DERM) handles water billing for most of Miami. You can pay your bill online through the county's website, by phone, by mail, or in person at a payment center. The online portal is the fastest option — you log in with your account number and pay when ready with a debit card, credit card, or bank account.

If you prefer to call, the payment line is available during business hours. You will need your account number and a payment method ready. For mail payments, write your account number on the check and send it to the address listed on your bill. In-person payments are accepted at DERM offices and authorized payment locations throughout the county.

  • Online payment through the county portal is the fastest method and processes when ready with a debit or credit card.
  • Your account number appears on your bill and is required for all payment methods except in-person cash payments at some locations.
  • Late payments may result in a reconnection fee or service suspension, so paying by the due date shown on your bill matters.
  • If you cannot pay the full amount, contact DERM to ask about payment plans or hardship programs before your account falls behind.

Setting Up Online Payments

The Miami-Dade County online payment system lets you pay one time or set up automatic payments. Go to the DERM website, select the water bill payment option, and enter your account number. You will be asked to create a login or use an existing account. Once logged in, you can view your current balance, payment history, and due date.

For a one-time payment, select the amount you want to pay and choose your payment method. Credit cards, debit cards, and bank account transfers are all accepted. The system will confirm your payment when ready, though it may take one to two business days to appear on your account. For automatic payments, you set the amount and frequency — most people choose to pay the full bill on the due date each month.

Phone and Mail Payment Options

To pay by phone, call the Miami-Dade water payment line during business hours. Have your account number and payment method ready. The representative will process your payment over the phone and give you a confirmation number. This method is useful if you do not have internet access or prefer to speak with someone.

Mail payments take longer — typically seven to ten business days to reach the county and post to your account. Write your account number clearly on the check or money order, and include the payment stub from your bill if possible. Mail payments to the address printed on your bill. Do not send cash through the mail. If your bill is due soon, mail is not the best choice because the payment must arrive and be processed before the due date to avoid a late fee.

In-Person Payment Locations

You can pay your water bill in person at DERM offices and authorized payment centers throughout Miami-Dade County. In-person payments are processed the same day, so your account is updated when ready. Some locations accept cash, checks, and cards, while others may have different payment method policies — call ahead if you have a specific payment method in mind.

Payment centers are located in different parts of the county to make it convenient. Hours vary by location, so check the DERM website or call to confirm hours before you go. Bring your account number or your bill with you. If you are paying someone else's bill, bring their account number and a form of identification.

Understanding Your Bill and Due Date

Your Miami water bill shows your account number, the amount owed, and the due date. The due date is typically 20 to 25 days after the bill is issued. If you pay after the due date, a late fee is added to your next bill. If your account becomes significantly overdue, the county may suspend your water service and charge a reconnection fee to turn it back on.

Your bill also shows your water usage for the billing period and the rate per gallon. If your usage seems unusually high, check for leaks in your home — a running toilet or hidden leak can cause a spike. Contact DERM if you believe there is an error on your bill; they can investigate and adjust it if needed.

What to Do If You Cannot Pay on Time

If you cannot pay your full bill by the due date, contact DERM before your account becomes late. The county offers payment plans for customers facing hardship. A payment plan lets you split your bill into smaller amounts over several months. You will need to discuss your situation with a representative to set up a plan that works for your budget.

Some customers may also be referred to community information programs that help with utility bills. DERM can tell you whether you may be referred to such a program based on your income and circumstances. The key is to reach out before you miss a payment — once an account is late, reconnection fees and additional charges make the total owed much higher.

Frequently Asked Questions

How do I find my account number?

Yes, the DERM online portal accepts credit cards, debit cards, and bank account transfers. There may be a small processing fee for credit card payments, so check the payment screen before you confirm. Debit cards and bank transfers typically have no fee.

What happens if I pay late?

Is there a way to lower my water bill?

Some customers also may have access to for conservation rebates if they install water-saving fixtures — contact DERM to ask about current programs.
