2026 Miami-Dade Residential Water and Sewer Rates

Miami-Dade’s water and wastewater rates effective October 1, 2026 are based on meter size and consumption. Residential water charges increase at higher usage levels.

The department measures consumption in hundred cubic feet, abbreviated ccf. One ccf equals approximately 748 gallons.

Residential Water Charges: October 2026–September 2027

Residential Wastewater Charges

These amounts apply to the published residential rate structure. Other meter sizes, customer categories and applicable charges can change the final bill.

Example: A Home Using 5,000 Gallons

Five thousand gallons is approximately 6.68 ccf. Under the published 5/8-inch meter water schedule, the first 3 ccf are included in the base charge and the remaining approximately 3.68 ccf are billed at the applicable first usage tier.

The water charge would be approximately $21.35 for that amount of consumption, before wastewater charges, other fees or adjustments.

Customers using 18 ccf or more may also be affected by applicable water-restriction surcharges under South Florida Water Management District rules.

Official rates: Miami-Dade Water and Sewer Rates, Fees and Charges.

How to Start Water Service at a Miami Address

New Miami-Dade customers can request water and sewer service using the county’s Self-Service Application (SSA). Before applying, confirm that the county provides water service at the property.

Documents Needed to Open an Account

• Government-issued photo identification, such as a driver’s license, state ID or passport.
• Complete water service address.
• Current mailing address and contact information.
• Proof of property ownership or signed lease agreement.
• Business name and federal tax identification details, if applying for a business account.

Submit the New Service Application

1. Open Miami-Dade Start Water Service.
2. Choose the online Self-Service Application option.
3. Sign in to your existing SSA profile or create one.
4. Select Apply for New Service.
5. Enter the requested service address, customer details and supporting documents.
6. Review the application for errors.
7. Submit the request and save the confirmation number.
8. Watch for an update from the Water and Sewer Department if additional information is required.

The county states that new service requests are typically processed within 3–5 business days. Submit the application before your move-in date whenever possible.

New Water Service Deposits and Fees

The county states that deposits are credited back after two years of good standing upon service termination, according to the applicable account conditions. The $45 service charge is applied to the first bill.

These charges relate to establishing an account and should not be confused with fees for constructing new water infrastructure or installing a new meter.

Transfer or Stop Miami Water Service When Moving

If you already have a Miami-Dade water account and are moving to another property served by the department, use the transfer-service option rather than opening an unrelated new account.

Transfer Water Service

1. Open the official Transfer Water and Sewer Service page.
2. Sign in to your Self-Service Application account.
3. Select Transfer Service under Service Requests.
4. Enter the new address.
5. Choose the dates for service to end at your current property and begin at the new one.
6. Review your mailing address and contact information.
7. Submit the transfer request and keep the confirmation number.

Stop Water Service

Customers moving outside the Miami-Dade Water and Sewer service area can request disconnection through their online account, customer service or an official service center.

Visit Manage Your Water and Sewer Account and select the stop-service option. Provide the requested termination date and forwarding address so the department can send the final bill or account correspondence.

Late Water Bill, Payment Extension and Reconnection

Miami-Dade generally sends residential water bills quarterly. The county states that a bill becomes past due when payment is not received within 21 days of the billing date.

After that period, a 10% late fee may be added. Customers who do not pay or request an extension can receive a final notice, after which their service may become eligible for disconnection.

Request More Time to Pay

1. Log in through the Miami-Dade water account portal.
2. Check the account’s due date and past-due balance.
3. Select the option to request a payment extension.
4. Review and submit the available extension request.
5. Keep confirmation of the arrangement and pay by the agreed deadline.

If your online account is unavailable, call 305-665-7477 and ask about payment-extension options.

Restore Water After Disconnection

After paying the amount required to restore service, you must call Miami-Dade Water and Sewer Customer Care at 305-665-7477.

Miami-Dade lists a $35 reconnection fee for each required visit. Restoration depends on payment verification and safe conditions at the property.

Official instructions: Reconnect Water Service.

High Miami Water Bill? Check Consumption and Possible Leaks

South Florida’s year-round warm climate makes irrigation use an important factor in household water consumption. A hidden pipe leak, running toilet or malfunctioning sprinkler system may increase a bill without obvious signs.

Because Miami-Dade commonly bills quarterly, a problem that goes unnoticed for several weeks can become expensive before the next statement arrives.

Check Your Bill Before Requesting an Investigation

1. Check the billing period. Note the number of days covered by the statement.
2. Compare consumption. Review previous billing cycles and the amount of water used in ccf.
3. Look for a continuous leak. Inspect toilets, irrigation systems, outdoor faucets and damp areas around the property.
4. Review recent work. Pool filling, new landscaping, plumbing repairs or additional occupants can affect consumption.
5. Use your online account. Check consumption history and payment details through the county portal.
6. Request a review if needed. Contact Miami-Dade if the increase remains unexplained.

Request a High Water Bill Investigation

Miami-Dade offers water bill investigations involving an inspection of the meter and meter box, together with a visual check of the property’s exterior for possible causes of increased usage.

The county states that this investigation is provided without charge when the bill is unusually high or consumption is at least 50% greater than average quarterly usage.

To request an investigation:

1. Open your Water and Sewer account.
2. Find the billing adjustment or high bill investigation option.
3. Review your usage and explain the suspected problem.
4. Submit the request and follow any instructions for additional details.
5. Alternatively, call 305-665-7477.

Underground Leak Adjustment and Pool Credits

Miami-Dade also allows customers to request an underground leak adjustment or pool credit under applicable rules. These are different types of adjustments, and eligibility depends on the specific circumstances.

If you repaired an underground leak, keep your plumber’s invoice, repair date and supporting evidence. For a pool credit, check the county’s conditions before assuming that water used to fill a swimming pool qualifies for reduced wastewater charges.

Water Main Break, Sewer Backup or No Water in Miami

Miami-Dade Water and Sewer operates a 24-hour emergency call center for water and wastewater infrastructure problems.

Emergency line: 305-274-9272

What to Do Before Reporting a Water Problem

1. Check whether the problem affects one faucet or the entire property.
2. Look for water escaping into the street, a broken meter cover or signs of a sewer backup without approaching unsafe infrastructure.
3. Ask nearby residents whether they also have low pressure or no water, if practical.
4. Prepare the exact address or nearest intersection.
5. Call the emergency number and explain whether you have a leak, water outage, unusual pressure or sewer issue.

If the problem is limited to private plumbing, a licensed plumber may be needed. For a suspected public water main break, contact the utility promptly.

Visit the Water and Sewer Contact page for additional department information.

Miami Water Utility Service Areas: Check Your Provider

Miami-Dade Water and Sewer serves much of the county, but some municipalities maintain separate water or wastewater systems. A Miami mailing address alone does not confirm which utility sends your bill.

For example, Hialeah, North Miami, North Miami Beach, Miami Beach and other municipalities may have different arrangements for drinking-water distribution or wastewater billing.

How to Check Who Serves Your Property

1. Check the provider name on your latest water bill.
2. Open the Miami-Dade Land Information Viewer.
3. Use the Water Service Area Boundary or WASD Customers map layers.
4. Find the general area of the property and identify the indicated service area.
5. Confirm the exact property address with the responsible utility before submitting an account application.

The water provider and wastewater provider may not be the same. If your sewer charge appears on a different statement, contact the agency identified on that bill.

Miami Drinking Water Quality and Annual Reports

Miami-Dade publishes annual drinking water supply and quality reports explaining its water sources, treatment and testing results. These reports are useful if you want to understand what the department tests for and whether the system has reported compliance issues.

The county’s water supply relies heavily on groundwater resources in South Florida. Water treatment and distribution requirements are monitored through applicable federal and Florida drinking-water standards.

To review the current available report:

1. Open Miami-Dade Water Quality Reports.
2. Select the latest published annual drinking-water report.
3. Review the detected substances, reported testing results and regulatory limits.
4. Check any notices specific to your local service area.
5. Contact the Water and Sewer Department if you have questions about the results or notice a sudden water-quality change.

The county lists its 2025 What’s on Tap? water-quality report among the available reports. Current incident-specific notices should be checked separately rather than relying only on an annual report.
