Where to pay your Miami water bill
Miami-Dade County's water and sewer service is run by the Miami-Dade Water and Sewer Department (WASD). You can pay your bill in four ways: online through the county website, by phone, by mail, or in person at a payment center.
The online portal at miamidade.gov/wasd is the fastest option. You'll need your account number (printed on your bill) and can pay immediately with a debit or credit card. There's no fee for online payments made directly through the county site.
By phone, call 311 (Miami-Dade's main line) or 786-891-2800 to reach WASD directly. A representative can process your payment over the phone using a debit or credit card. Payments made this way are typically posted within one business day.
If you prefer to mail a check or money order, send it to the address printed on your bill. Allow 7 to 10 days for the payment to reach and post to your account. Always include your account number on the check.

In-person payment locations and hours
Miami-Dade WASD operates payment centers in several locations across the county. The main office is at 2600 Bayshore Boulevard in Coconut Grove. Hours vary by location, but most are open Monday through Friday, 8 a.m. to 5 p.m., and some locations have limited Saturday hours.
You can pay in cash, by check, or with a debit or credit card at any payment center. Bring your bill or account number. If you're unsure which location is closest to you, call 311 and ask for the nearest WASD payment center, or check the county website for the current list of addresses and hours.
Setting up automatic payments
If you want to avoid thinking about your water bill each month, you can set up automatic payments through the WASD online portal. This option deducts your payment from your bank account on a date you choose, typically around your due date.
To enroll, log into your account at miamidade.gov/wasd and look for the autopay or recurring payment option. You'll provide your bank account information once, and the system will process payments automatically each billing cycle. You can change or cancel autopay at any time through the same portal.
Understanding your due date and late fees
Your water bill due date is printed on the front of your bill, usually 20 to 25 days after the bill is issued. If payment is not received by that date, Miami-Dade WASD will charge a late fee. The exact amount of the late fee varies but is typically a percentage of your bill or a flat fee — check your bill or call 311 for the current rate.
If your bill is significantly overdue, the county may place a lien on your property or shut off your water service. If you cannot pay by the due date, contact WASD immediately at 311 or 786-891-2800 to discuss payment arrangements or hardship programs that may be available to you.
What to do if you don't receive your bill
Bills are mailed about 20 days before the due date. If you haven't received yours within that window, contact WASD at 311 or 786-891-2800 to confirm your mailing address is correct and request a duplicate bill.
You can also view your bill online anytime by logging into your account at miamidade.gov/wasd. Your online account shows your current balance, payment history, and due date. Even if your physical bill hasn't arrived, you can pay online using the information in your account.
Paying a bill for a property you're selling or leaving
If you're moving out of a Miami-Dade property, you'll need to settle your water account before you leave. Contact WASD at 311 or 786-891-2800 to request a final bill. The final bill covers water use through your move-out date and any remaining balance.
Pay the final bill by your due date to avoid late fees or a lien on the property. If you're selling the property, the title company or closing attorney will often handle the final water bill as part of closing costs, but confirm this with your real estate agent or attorney beforehand.
