Where to pay and what payment methods work
Miami-Dade Water and Sewer Department accepts payments online, by phone, by mail, and in person at their offices. The online portal at miamidade.gov/wasd is the fastest route — you can pay immediately with a bank account or debit card, and you'll see confirmation right away. No account login is required; you can pay as a guest using your account number from your bill.
By phone, call the department's customer service line at 305-668-6680 during business hours (Monday through Friday, 8 a.m. to 5 p.m.). A representative will process your payment over the phone using a debit or credit card. This method takes a few minutes but gives you a confirmation number on the spot.
If you prefer to mail a check or money order, send it to the address printed on your bill — typically Miami-Dade Water and Sewer Department, P.O. Box 330010, Miami, FL 33233. Mail payments take 7 to 10 business days to reach the department and post to your account, so send early if your due date is approaching.
In-person payments are accepted at the main office at 2600 Tigertail Avenue, Miami, FL 33134, and at some satellite locations. Call ahead to confirm hours and location before you go, since office hours vary by site.

Understanding your bill and account number
Your Miami-Dade water and sewer bill shows your account number in the top right corner — this is what you need to make a payment. The bill also lists your due date, usually 20 days from the billing date. If you pay after the due date, a 10 percent late penalty is added to your balance.
The bill breaks down charges into water usage (measured in gallons), sewer service, and any other fees or adjustments. Your usage is read from a meter at your property, usually once a month. If you want to check your usage between bills or look at your payment history, you can log into your account on the department's website using your account number and service address.
If you cannot find your account number, look at any past bill or call customer service at 305-668-6680. They can look up your account using your service address and phone number.
Setting up automatic payments to avoid missing due dates
The Miami-Dade Water and Sewer Department offers automatic payment enrollment through their website. You can set up a recurring payment from your bank account on a date you choose — typically a few days before your due date. This removes the risk of forgetting to pay and incurring a late fee.
To enroll, go to miamidade.gov/wasd, select the autopay option, and enter your bank account details. You can change or cancel autopay at any time through the same portal. If you prefer not to use the online system, call 305-668-6680 and ask a representative to set it up over the phone.
Automatic payments are deducted from your account on the date you specify, and you'll receive a confirmation email. If your bill amount changes month to month (which is normal for water usage), you can set autopay to deduct whatever the current bill is, rather than a fixed amount.
What to do if you cannot pay by the due date
If you know you will miss your due date, contact the department before the date arrives. Call 305-668-6680 and explain your situation. The department may be able to work out a payment arrangement or extend your due date in some cases, though this is not may provide.
If your account falls behind, the department will send you a notice. Continued non-payment can result in service disconnection — water and sewer service can be shut off if your account is significantly overdue. The department typically sends multiple notices before disconnecting service, so you will have warning.
If you are struggling with your bill because of a financial hardship, ask about the Utility Assistance Program when you call. This program may help cover part of your bill if you meet income requirements. The representative can tell you whether you might be may be able to access and how to proceed.
Checking your payment status and account history
After you make a payment, you can verify it posted to your account by logging into the online portal at miamidade.gov/wasd. Online and phone payments usually show within one business day. Mailed payments take longer — typically 7 to 10 business days — so do not assume a check was lost if it does not appear immediately.
The online portal also shows your payment history, past bills, and current balance. This is useful if you need to confirm that a payment went through or if you want to review your usage over time. If you see an error or have questions about a charge, you can contact customer service at 305-668-6680 to dispute it.
If you need a receipt or proof of payment for your records, the online system generates one automatically after you pay. For mailed payments, keep your cancelled check or money order receipt as proof.
Payment deadlines and late fees explained
Your due date appears on your bill statement. Payments must be received by the department by that date to avoid a late fee. A 10 percent penalty is added to any balance not paid by the due date. For example, if your bill is $100 and you pay one day late, you owe $110.
The penalty applies to the unpaid balance, not just the overdue portion. If you pay part of your bill by the due date and the rest later, the late fee applies only to the portion paid after the due date.
If your account becomes significantly overdue (typically 60 days or more), the department may issue a notice of intent to disconnect service. This gives you a final opportunity to pay before water and sewer service is shut off. Once service is disconnected, a reconnection fee applies in addition to your unpaid balance.
Frequently Asked Questions
Can I pay my bill with a credit card online?
Yes, the online portal accepts debit and credit cards. You can also pay by credit card over the phone at 305-668-6680. Be aware that some credit card companies may charge a cash advance fee for utility payments, so check with your card issuer first.
How long does it take for an online payment to show on my account?
Online payments typically post within one business day. Phone payments show immediately and come with a confirmation number. Mailed checks take 7 to 10 business days to clear and post to your account.
What happens if I pay the wrong amount?
