How to pay Miami-Dade water and sewer charges
Miami-Dade County's water and sewer utility is run by the Miami-Dade Water and Sewer Department. You can pay your bill online through their website, by phone, by mail, or in person at a payment center. The fastest way is online through the department's bill pay portal, which processes payments the same day you submit them during business hours.
Your bill arrives monthly and shows your account number, the amount due, and the due date. Late payments trigger a penalty, so paying by the due date matters. If you set up automatic payments, the department withdraws the amount directly from your bank account on a date you choose, and you won't have to remember to pay each month.
Key Takeaways
- You can pay online at the Miami-Dade Water and Sewer Department website, by phone at 305-668-9282, by mail, or at a walk-in payment center.
- Online and phone payments process the same day if you submit them before 5 p.m. on a business day.
- Setting up automatic payments means the department withdraws your bill amount on a schedule you set, so you never miss a due date.
- Late payments add a penalty to your next bill, so paying by the due date shown on your statement matters.
- If you cannot pay the full amount, contact the department to discuss a payment plan before your account falls behind.
Paying online through the Miami-Dade portal
The Miami-Dade Water and Sewer Department runs an online payment portal where you can pay with a debit card, credit card, or bank account. Go to the department's website, find the "Pay Your Bill" or "Online Payments" section, and enter your account number (printed on your bill). You will need to create a login or use an existing one.
Once you log in, your current balance appears on screen. You can pay the full amount or a partial payment. Enter your payment method details and the amount you want to pay. The system will confirm the payment when ready. Keep the confirmation number for your records — you may need it if you call the department later with a question.
Online payments made before 5 p.m. on a business day post to your account the same day. Payments made after 5 p.m. or on weekends and holidays process the next business day. There is no fee to pay online through the department's official portal.
Paying by phone or automatic withdrawal
Call the Miami-Dade Water and Sewer Department at 305-668-9282 to pay by phone. A representative will ask for your account number and the amount you want to pay, then take your debit card, credit card, or bank account information. Phone payments also process the same day if you call before 5 p.m. on a business day.
To set up automatic payments, you can do this online through the portal or by calling the department. You provide your bank account information once, and the department withdraws your bill amount on a date you choose each month. Automatic payments are free and remove the risk of forgetting to pay. If your bill amount varies month to month (as water bills often do), the department will withdraw whatever the current balance is on the date you set.
Paying by mail or at a payment center
To pay by mail, write a check or money order for the amount due and include your account number on the check. Mail it to the address shown on your bill. Mail payments take longer to reach the department and post to your account — typically five to seven business days after they arrive. If your due date is soon, mailing a check risks a late payment penalty, so use online or phone payment instead.
Miami-Dade Water and Sewer Department has walk-in payment centers in several locations around the county. You can pay in person with cash, check, or card at these centers during business hours. Check the department's website for the nearest location and hours before you go. In-person payments post to your account the same day.
What happens if you miss a payment
If your payment does not arrive by the due date on your bill, the department adds a late penalty to your next bill. The penalty amount depends on how late the payment is. If you fall significantly behind, the department may shut off your water service. Once service is shut off, you must pay the full past-due balance plus a reconnection fee to restore water to your property.
If you know you cannot pay the full amount by the due date, contact the Miami-Dade Water and Sewer Department before the due date passes. The department may be able to set up a payment plan that lets you pay in installments over time. This avoids the late penalty and keeps your service active while you catch up.
Understanding your bill and account number
Your Miami-Dade water bill shows your account number at the top, usually a six- to eight-digit number. You need this number to pay online, by phone, or to contact the department with questions. The bill also lists your service address, the billing period, the amount due, and the due date. If you receive a paper bill by mail, keep it in a safe place until you pay it.
Your bill includes charges for water consumption (measured in gallons), sewer service, and sometimes stormwater fees. The amount you owe depends on how much water you used during the billing period. If you notice your bill is much higher than usual, you may have a leak. Contact the department to report an unusually high bill — they can sometimes adjust charges if a leak was the cause.
Setting up paperless billing and payment reminders
Many people sign up for paperless billing through the Miami-Dade Water and Sewer Department portal so they receive email notifications when a new bill is ready instead of waiting for a paper bill in the mail. Paperless billing is free and gets the bill to you faster. You can still pay online, by phone, or by mail — paperless billing just changes how you receive the bill.
Some people also set calendar reminders on their phone for a few days before the due date, even if they have automatic payments set up. This way, if there is ever a problem with the automatic withdrawal, you will notice and can pay manually before a late penalty hits. The due date is always printed on your bill.
Frequently Asked Questions
Can I pay someone else's Miami-Dade water bill?
Yes. You can pay online using their account number, by phone if you provide their account number, or by mail if you include their account number on the check. The department does not require you to be the account holder to make a payment.
What if I pay online but the payment does not show up?
Check your confirmation number and the date you submitted the payment. Online payments take until the end of the business day to post. If more than one business day has passed and the payment still does not appear, call 305-668-9282 with your confirmation number and account number so the department can look it up.
Is there a fee to pay my water bill online?
No fee through the official Miami-Dade Water and Sewer Department portal. Some third-party payment services may charge a fee, so use the department's own website to avoid extra charges.
Can I set up automatic payments for a partial amount?
Automatic payments typically withdraw your full bill amount each month. If you want to pay a different amount, contact the department at 305-668-9282 to discuss options or set up a custom payment plan.
What if my water service was shut off for non-payment?
Pay the full past-due balance plus the reconnection fee. You can do this online, by phone, or at a payment center. Once the payment posts and clears, the department will restore your service, usually within one business day.
