Where to pay your Miami-Dade water bill
Miami-Dade Water and Sewer Services (MDWASD) gives you four main ways to pay: online through their website, by phone, by mail, or in person at a payment center. The fastest and most convenient route for most people is online payment through the MDWASD website — you can do it any time, day or night, and see your payment post within one to two business days.
If you prefer not to use the internet, you can call the automated phone line at 786-891-2900 to pay by debit or credit card. This line operates 24 hours a day. You will need your account number (printed on your bill) and a valid card ready when you call.
Mailing a check or money order is slower but works if you do not have online access or a card. Mail payments to the address printed on your bill — typically Miami-Dade Water and Sewer Services, P.O. Box 24570, Miami, FL 33124. Allow 10 to 14 days for the mail to arrive and be processed, so send it well before your due date to avoid a late fee.
Key Takeaways
- Online payment through the MDWASD website is the fastest option and posts within one to two business days.
- The automated phone line at 786-891-2900 accepts debit and credit card payments 24 hours a day and requires only your account number.
- In-person payment centers are located throughout Miami-Dade County and accept cash, check, or card — bring your bill or account number.
- Mailed checks take 10 to 14 days to process, so send payment at least two weeks before your due date to avoid late fees.
- Your bill shows the due date, the amount owed, and your account number — you will need the account number for any payment method.
Paying online through the MDWASD website
Go to miamidade.gov/wasd and look for the "Pay My Bill" or "Online Bill Pay" link on the homepage. You will be asked to enter your account number and either your service address or the amount of your bill to find your account. Once you locate it, you can review the balance and choose your payment amount.
The website accepts debit cards, credit cards, and bank account transfers (ACH). Credit and debit card payments typically process within one to two business days. Bank account transfers may take slightly longer. There is no fee for paying by bank transfer, but credit and debit card payments may include a small processing fee — the website will show you the exact amount before you confirm.
After you submit your payment, you will receive a confirmation number on screen. Write this down or take a screenshot. If you do not see the payment post to your account within two business days, contact MDWASD at 786-891-2900 with your confirmation number.
Paying by phone or automated system
Call 786-891-2900 to reach the automated payment system. You will need your account number (on your bill) and a debit or credit card. The system will guide you through entering your card information and the amount you want to pay. The call is free, and you can pay any time of day or night.
If you prefer to speak with a person, you can call the same number during business hours — typically Monday through Friday, 8 a.m. to 5 p.m. — and ask to be transferred to a customer service representative. A representative can also help you set up a recurring payment if you want the same amount deducted on the same day each month.
Paying in person at a Miami-Dade payment center
MDWASD operates payment centers throughout Miami-Dade County where you can pay in cash, by check, or by card. These centers accept walk-in payments during regular business hours. Bring your bill or your account number so the staff can locate your account quickly.
Payment centers are typically located in government buildings and service centers across the county. To find the one nearest you, call 786-891-2900 and ask for the address and hours of the closest location, or visit the MDWASD website and look for a "Payment Locations" or "Service Centers" page.
In-person payment is processed immediately, so your payment will show on your account the same day. This is useful if you are close to your due date and want to avoid a late fee without waiting for mail or online processing.
Understanding your bill and due date
Your Miami-Dade water bill shows several key pieces of information: your account number, your service address, the amount due, and the due date. The due date is usually 20 to 25 days after the bill is mailed. If you pay after the due date, MDWASD will add a late fee to your next bill.
Your bill also shows your water and sewer usage for the billing period, measured in gallons or hundred cubic feet (HCF). If your usage seems unusually high, check for leaks in your home — a running toilet or dripping pipe can add hundreds of gallons to your bill. If you think there is an error, contact MDWASD to request a meter check or bill review.
Setting up automatic payments
If you want to avoid remembering due dates, you can set up automatic monthly payments through the MDWASD website or by calling 786-891-2900 and speaking with a representative. Automatic payments deduct the same amount from your bank account or card on the same day each month.
Before you set up automatic payments, make sure the amount covers your typical bill. If your usage varies seasonally — for example, if your bill is higher in summer when you water your lawn — you may want to set the automatic payment to a higher amount so you do not fall short. You can change or cancel automatic payments at any time through the website or by calling customer service.
What to do if you cannot pay on time
If you know you will miss your due date, contact MDWASD as soon as possible at 786-891-2900. Depending on your account history and circumstances, they may be able to work out a payment plan that spreads your bill over two or more months. Payment plans are not automatic — you must request one before your account becomes delinquent.
If your account falls behind, MDWASD may charge a late fee, suspend service, or refer your account to a collection agency. These actions make the debt harder and more expensive to resolve. Calling early to discuss options is always better than waiting.

Can I set up automatic payments for a different amount each month?
