Where to pay your Miami-Dade water and sewer bill
Miami-Dade County's Water and Sewer Department operates a dedicated payment system separate from other county services. You can pay through their official website at miamidade.gov/wasd, by phone, by mail, or in person at payment centers. The online portal is the fastest route — payments post within one business day when you pay before 5 p.m. Eastern time on a weekday.
The department does not use third-party bill pay services or allow payments through the main county website. You must use the Water and Sewer Department's own system. This matters because sending a check to the wrong address or using an unauthorized payment method can delay posting and trigger late fees.
Key Takeaways
- Online payment through miamidade.gov/wasd posts within one business day and requires your account number and billing address to log in.
- Phone payments (786-891-2685) are processed the same day but charge a convenience fee of roughly $2 to $3 depending on payment amount.
- Mail payments should be sent to the address on your bill, not to a general county office, and take 7 to 10 business days to post after mailing.
- In-person payments at Water and Sewer payment centers post when ready and do not carry a convenience fee.
- Late fees begin 15 days after your due date, so paying by the due date shown on your bill prevents additional charges.
Paying online through the Water and Sewer portal
The online payment system is the most common method. Go to miamidade.gov/wasd and select "Pay Your Bill" or "Online Bill Pay." You will need your account number (found on your bill) and your billing address to create a login or access your account as a guest.
Once logged in, you can review your current balance, past payments, and due date. The system accepts debit cards, credit cards, and bank account transfers. Credit card payments may carry a small fee — check the screen before confirming. Bank account payments typically have no fee. After you submit payment, you receive a confirmation number when ready. The payment posts to your account within one business day.
If you do not have your account number, you can search for your account using your service address instead. The portal also allows you to set up automatic recurring payments if you want the same amount charged on the same date each month.
Paying by phone or automated system
Call the Water and Sewer Department's automated payment line at 786-891-2685. The system accepts debit and credit card payments only — not bank account transfers. A convenience fee applies to all phone payments, typically $2 to $3 depending on your payment amount. The fee is added to your bill, not charged separately at the time of payment.
Payments made before 5 p.m. Eastern time on a weekday post the same day. Payments made after hours or on weekends post the next business day. You will receive a confirmation number at the end of the call. Keep this number for your records in case you need to dispute the payment later.
If you prefer to speak with a representative rather than use the automated system, you can call 786-891-2685 during business hours and ask to be transferred to a customer service agent. Agents can also answer questions about your account balance, payment history, or billing disputes.
Paying by mail
Write a check or money order payable to "Miami-Dade County Water and Sewer Department." Include your account number on the check. Mail your payment to the address printed on your bill — this address varies by billing district and using the wrong address delays posting.
Mail payments typically take 7 to 10 business days to post after you mail them. The postmark date is not the same as the date the payment is received, so mail your payment at least 10 days before your due date to avoid late fees. If your payment is postmarked on or before the due date but arrives late, the department may still consider it on time — contact them to confirm if this happens.
Keep a copy of your check or money order receipt and note the date you mailed it. If your payment does not appear on your account within two weeks, contact the department to confirm they received it.
Paying in person at a payment center
Miami-Dade County operates several Water and Sewer payment centers where you can pay cash, check, debit card, or credit card in person. Payments made in person post when ready — you do not have to wait for processing. No convenience fee is charged for in-person payments.
Payment center locations and hours are listed on miamidade.gov/wasd under "Payment Locations." Centers are typically open Monday through Friday during standard business hours. Some locations may have extended hours or Saturday hours — check the website for the location nearest you before you go.
Bring your account number or billing address so staff can locate your account. If you pay by check, bring a photo ID. If you pay cash, ask for a receipt showing the date, amount, and your account number.
Understanding your bill and due dates
Your water and sewer bill shows your service address, account number, current charges, any previous balance owed, and the due date. The due date is typically 20 days from the bill date. Payments received after the due date are considered late, and a late fee is added to your next bill.
Late fees begin 15 days after your due date. If your bill is due on the 20th and you pay on the 25th, you are late but may not see a fee on that bill — it appears on the next one. If you pay after the 35th, the late fee is applied when ready. The amount of the late fee is a percentage of your balance and varies based on your account history.
If you believe your bill is incorrect or you have a dispute about charges, contact the department before the due date. Paying the full amount by the due date does not waive your right to dispute — you can pay and file a dispute at the same time.
What to do if you cannot pay by the due date
If you cannot pay your full bill by the due date, contact the Water and Sewer Department at 786-891-2685 to discuss your options. The department may offer a payment plan that allows you to pay your balance in installments over several months. Payment plans typically require a down payment and monthly payments that include a small fee.
Requesting a payment plan before your account becomes severely past due improves your chances of approval. If your account falls more than 60 days behind, the department may issue a notice of intent to discontinue service. Service can be shut off without further notice once this stage is reached.
If you are experiencing financial hardship, ask about hardship programs or bill information. Some community organizations in Miami-Dade offer water bill information to low-income households, though these programs are separate from the county department.
Frequently Asked Questions
Can I pay my water bill with a credit card online without a fee?
Credit card payments through the online portal may carry a fee — the system will show you the fee amount before you confirm payment. Bank account transfers through the online portal typically have no fee. Phone payments always charge a convenience fee regardless of payment method.
What happens if I mail my check and it gets lost?
If your check does not post within two weeks of mailing, contact the department with your check number and amount. They can search their records to see if the payment was received. If it was not received, you may need to stop payment on the original check and send a new payment to avoid late fees.
Can I set up automatic payments so I do not have to pay every month?
Yes. The online portal allows you to set up recurring automatic payments from a bank account or card. You choose the payment amount and the date each month. You can change or cancel automatic payments anytime through your online account.
Do I need to create an online account to pay my bill?
No. The online portal offers a guest payment option where you enter your account number and billing address without creating a login. Guest payments post the same way as payments from a registered account. Creating an account is optional and useful only if you want to view your payment history or set up automatic payments.
What is the difference between my water bill due date and when the payment must post?
Your due date is when payment is expected. Payments received by the due date are on time. Payments received after the due date are late, even if they post the same day. Mail payments should be sent 10 days before the due date to account for delivery time.
