How to pay your Miami-Dade water bill
Miami-Dade Water and Sewer Department lets you pay your bill through their website, by phone, by mail, or in person at a payment center. The fastest method is online through their bill pay portal at miamidade.gov/water, where you can pay when ready with a bank account or debit card. If you prefer not to use the internet, you can call their customer service line at 305-668-9822 to pay by phone with a debit or credit card, or mail a check to the address printed on your bill.
Your bill arrives monthly and shows what you owe, when it is due, and the account number you will need to make a payment. The due date is typically 20 days after the bill date. If you pay after the due date, a late fee applies. Knowing your account number before you start makes any payment method faster — you can find it on your bill or in your online account.
Key Takeaways
- Online payment through miamidade.gov/water is the fastest option and processes when ready when you use a bank account or debit card.
- Phone payment at 305-668-9822 takes a few minutes and works with debit or credit cards during business hours.
- Mail payments should be sent to the address on your bill and take 7 to 10 days to reach the department and post to your account.
- Late fees begin if you pay after the due date shown on your bill, so setting a reminder for a few days before helps you avoid them.
- Your account number appears on your bill and in your online account, and you will need it for any payment method except in-person payments.
Paying online through the Miami-Dade website
The online portal at miamidade.gov/water is the most direct way to pay. Go to the website, select "Pay Your Bill," and enter your account number and the amount you want to pay. You will then choose a payment method — either a bank account (which takes one business day to process) or a debit card (which posts when ready). The site will ask for your banking information or card details and a billing address to confirm your identity.
Online payments do not cost extra. Once you submit your payment, the system gives you a confirmation number right away. Write down or save this number in case you need to reference the payment later. If you set up an online account on the Miami-Dade website, you can also see your payment history and upcoming bills in one place, which helps you track what you owe.
Paying by phone
Call Miami-Dade Water and Sewer Department at 305-668-9822 to pay by phone. Have your account number and a debit or credit card ready. A representative will walk you through the payment, confirm the amount, and give you a confirmation number when the transaction is complete. Phone payments are available during business hours, which vary by season — the department publishes their hours on their website.
Phone payments process the same day you call. There is no fee for paying this way. If you are not sure of your account number, the representative can look it up using your address and name, though having the number ready makes the call shorter.
Paying by mail
Write a check or money order payable to Miami-Dade Water and Sewer Department. Include your account number on the check. Mail it to the address printed on your bill — this address is where the department processes payments. Mail payments typically take 7 to 10 days to arrive and post to your account, so send your payment at least two weeks before the due date if you want to avoid a late fee.
Keep a copy of the check or money order for your records. If you are concerned about whether your payment arrived, you can log into your online account a few days after you mail it to see if the payment has posted. The department does not charge a fee for mailed payments.
In-person payment at a service center
Miami-Dade Water and Sewer Department operates payment centers where you can pay in person with cash, check, or card. Locations and hours are listed on their website at miamidade.gov/water. Bring your bill or account number and your payment method. In-person payments post to your account the same day.
This option works well if you prefer to hand over payment directly or if you do not have online or phone access. There is no fee for paying in person.
What to do if you miss the due date
If you pay after the due date shown on your bill, Miami-Dade Water and Sewer Department charges a late fee. The amount of the late fee depends on your bill total and is shown on your next bill. Paying late does not stop your service when ready, but if your account falls far enough behind, the department may issue a notice of intent to discontinue service.
If you are having trouble paying on time, contact the department at 305-668-9822 to ask about payment plans or hardship programs. Some customers may be able to set up a plan to pay what they owe over several months instead of all at once. The sooner you reach out, the more options you may have.
Setting up automatic payments
You can set up automatic payments through your online account on miamidade.gov/water so that your bill is paid on the same day each month without you having to remember. Choose the amount you want to pay and the date, and the system will deduct it from your bank account automatically. You can change or cancel automatic payments anytime through your account.
Automatic payments reduce the risk of paying late and give you one less bill to think about each month. If your bill amount changes significantly from month to month, you can set up automatic payment for a fixed amount and then pay any difference manually, or you can update the automatic amount as needed.
