Thank you for your patience as we improve our online services.

Water Bill Adjustments

There may be several reasons why you received a high water bill in the most recent quarter.

Customers may receive an adjustment to their bill in any of these cases:

  • a high bill due to a leak that was concealed underground or behind a wall
  • an act of vandalism resulting in a high bill (customer must have reported the incident to the police, and must verify repairs made to damaged water and sewer fixtures)
  • an over or underestimated reading
  • an incorrect meter reading

To request a leak credit, please complete an underground / concealed leak credit request form . Be sure to indicate the date and location on the property of the repairs. Fax the completed form to 786-552-8763 or mail to

PO BOX 330316 
MIAMI FL 33233-3016

Be sure to indicate "Leak Credit" on the fax sheet or envelope.

No adjustments will be made for leaks occurring in visible fixtures such as toilets, hot water heaters, faucets or exposed plumbing (including pipes in an under-the sink cabinet, for example).

A pool credit is available under certain conditions.

Deposit refunds

Customers in good standing may request their full deposit amount to be credited to their account after two years of good credit history with the Miami-Dade Water & Sewer Department or at termination of service. For more information, call Miami-Dade Water & Sewer Department Customer Service at 305-665-7477.

Certified meter request

A "legally accurate" meter is defined as a meter that has been tested by the Water & Sewer Department and is determined to register between 98.5 and 101.5 percent on high and intermediate test flows, and between 90.0 and 101.0 on low test flows. Certified meter tests take up to 60 days to complete. The test results will be mailed to you within 10 working days upon completion. The Department will notify you regarding any discrepancies with this request.

To request a certified meter test, please fill out a certified meter request form . Fax the completed form to 786-552-8763 or mail it to:

3071 SW 38TH AVENUE - ROOM 247
MIAMI FL 33146-1520


In the event of an extremely high bill, a one-time lifetime credit may be granted at the discretion of the Water and Sewer Department Director.
