How Miami-Dade Water Charges Reach Your Account

Miami-Dade Water and Sewer Services (MDWSS) bills residential and commercial customers monthly based on meter readings taken by the county. The charge appears on a single bill that combines water usage, sewer service, and stormwater fees. Your meter is read on a schedule tied to your account number, not a fixed calendar date, so billing cycles vary across the county.

The bill itself is generated by MDWSS and mailed to the address on file, or you can view it online through your account portal. Payment is due by a specific date printed on the bill — typically 20 to 25 days after the bill date. If you do not pay by that date, a late fee is added to your next bill. The county does not charge interest on overdue balances, but service can be disconnected if the account falls 60 days past due.

Key Takeaways

  • Miami-Dade Water bills are mailed monthly and combine water, sewer, and stormwater charges into one statement.
  • You can pay online through the MDWSS customer portal, by phone, by mail, or in person at county payment centers.
  • Payment is due within 20 to 25 days of the bill date; late fees explore if you miss the important date.
  • The county offers budget billing and payment plans for customers who want to spread costs or stabilize monthly charges.
  • Service disconnection begins after 60 days of non-payment, but you can request a payment arrangement before that point.

Payment Methods and Where the Money Goes

MDWSS accepts payment through four main channels: online via the customer portal at miamidade.gov/water, by phone through an automated system or live representative, by mail to the address listed on your bill, or in person at Miami-Dade County payment centers located throughout the county. Online and phone payments are processed when ready and do not require a stamp or trip to an office. Mail payments take 7 to 10 business days to post to your account, so send them early if your due date is approaching.

Once the county receives your payment, it is deposited into the Miami-Dade Water and Sewer Services operating fund. That money is then allocated to three areas: water treatment and delivery (the largest share), sewer collection and treatment, and stormwater management. The county publishes an annual budget that breaks down how much of each customer's bill funds each service. For example, in a typical residential bill, roughly 40 percent covers water supply, 45 percent covers wastewater treatment, and 15 percent covers stormwater.

The county does not separate these charges on your bill — you pay one combined amount — but you can request a breakdown by calling MDWSS customer service. If you dispute a charge or believe your meter is reading incorrectly, the county will investigate at no cost to you, though the process typically takes 30 to 45 days.

Online Payment Portal and Account Management

The MDWSS online portal allows you to view your current and past bills, set up automatic payments, and make one-time payments without calling or visiting an office. To access it, you need your account number (found on your bill) and a password you create during registration. The portal is available 24 hours a day, seven days a week.

Automatic payments can be scheduled for any date you choose, and you can change or cancel them at any time. Many customers set automatic payments for the due date to avoid late fees. If you set up automatic payment, you will still receive a bill in the mail or email (if you have opted into paperless billing) showing what was charged and what will be paid.

Budget Billing and Payment Plans

If your water bill varies significantly from month to month — for example, if you use more water in summer — you can request budget billing. Under this program, MDWSS calculates your average monthly charge based on the past 12 months of usage and bills you that same amount each month. At the end of the year, the account is reconciled: if you used more than the average, you pay the difference; if you used less, the credit rolls to the next year or is refunded.

Budget billing is free and can be requested through the online portal or by calling MDWSS customer service. It does not reduce your total annual bill — it only spreads the cost evenly — but it makes budgeting easier for households with variable usage patterns.

If you fall behind on payments, the county offers payment arrangements for accounts that are past due. You must contact MDWSS before the account reaches 60 days overdue to negotiate a plan. Arrangements typically allow you to pay the overdue balance in installments over 30 to 90 days while continuing to pay current bills on time. If you miss a payment under an arrangement, the plan can be cancelled and disconnection proceedings may resume.

Late Fees, Disconnection, and Reconnection

A late fee is added to your account if payment is not received by the due date. The fee amount is set by county ordinance and is typically a percentage of the bill or a flat amount, whichever is greater. Late fees are added to your next bill and become part of the amount owed.

If your account reaches 60 days past due, MDWSS sends a final notice of intent to disconnect. You then have a grace period (usually 10 to 15 days) to pay the full overdue amount or arrange a payment plan. If you do not respond, the county schedules a disconnection date. Service is typically shut off by cutting the meter or capping the line, and the account is flagged as disconnected.

To reconnect, you must pay the full overdue balance plus a reconnection fee set by the county. Reconnection is not automatic — you must request it through customer service, and it may take one to three business days to schedule. If the disconnection was due to non-payment, reconnection fees are non-waivable, even if you have a hardship.

Billing Disputes and Meter Accuracy

If you believe your bill is incorrect or your meter is malfunctioning, you can file a dispute through the online portal or by calling MDWSS customer service. The county will not disconnect your service while a dispute is under review, but you must continue paying the undisputed portion of your bill to avoid late fees.

MDWSS will investigate the dispute by reviewing your usage history, checking for leaks, and testing the meter if necessary. If the meter is found to be inaccurate, the county will adjust your bill retroactively, usually back to the date the meter began malfunctioning (or up to 12 months, whichever is shorter). If no error is found, you are responsible for the full bill.

Meter testing is free when requested as part of a dispute. If you request a test and the meter is found to be accurate, you pay nothing. If you request a test outside of a dispute process (for example, because you suspect a leak), the county may charge a service fee, though this is waived in some cases if the test confirms a problem.

information Programs for Low-Income Customers

Miami-Dade County does not operate a direct water bill subsidy program, but low-income customers may be able to reduce their bills through conservation rebates or by addressing water waste. The county also partners with community action agencies that may help with water bills as part of broader utility information. These programs vary by location within the county and change year to year.

If you are experiencing hardship, contact MDWSS customer service to ask about available resources. You can also reach out to your local community action agency or 211 (a free referral service) to learn what information may be available in your area. While the county cannot waive water bills, it may be able to extend a payment arrangement or connect you with an agency that can help.

Frequently Asked Questions

Can I pay my Miami-Dade water bill with a credit card?

Yes, the online portal and phone payment system both accept credit and debit cards. There is no fee for paying with a card through the official MDWSS channels. Some third-party payment processors may charge a fee, so always pay through miamidade.gov/water or the official phone line to avoid extra charges.

What happens if I move and forget to update my address?

Your bill will continue to be mailed to the old address, and you may miss the due date. Contact MDWSS when ready with your new address so future bills are sent to the correct location. If you have already missed a payment, call to arrange a plan before the account reaches 60 days past due.

How do I know if my meter is being read correctly?

MDWSS reads meters on a monthly schedule, and the reading date is printed on your bill. If you suspect the meter is wrong, compare your usage to previous months — a sudden spike may indicate a leak or malfunction. You can request a meter test through the dispute process at no cost.

Can I set up automatic payments if I have a payment plan?

Yes, automatic payments can be set up for any account, including those on payment arrangements. Make sure the automatic payment amount covers both the current bill and the installment due under your plan so you do not fall behind.

What if I cannot pay my full bill by the due date?

Contact MDWSS customer service before the due date to discuss options. The county may be able to extend the due date, set up a payment plan, or connect you with information resources. Waiting until after the due date to contact them limits your options and results in late fees.
