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

Leak Credit Request

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).

One-time Lifetime Credit

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.


Per Section 32-101 of the Code of Miami-Dade County, the Director of Miami-Dade Water and Sewer Department is given discretion to provide a one-time lifetime credit to a customer who disputes a high bill. The credit will be based upon the assessment of extreme circumstances in which a customer received a bill that exceeds six times the past year's average.

In order to be considered for the one-time lifetime billing adjustment for extreme circumstances:

  • The customer must be in good standing with the Department. This is defined as a customer who has not had the water disconnected for nonpayment, or the account placed in collection, during the previous 12 months.
  • The customer must submit their request form with an original notarized affidavit stating that a licensed plumber has checked the residence, inside and outside, for leaks (both concealed and visible leaks); that the customer did not leave a hose running inadvertently or otherwise allow water to flow for any period of time; and that there have been no changes in water usage within the household during the billing period  (i.e. new landscaping, guests visiting, major household repairs or construction that required increased water usage, problems with one's pool or sprinkler system or water theft.)

To be considered, please print and complete the respective form. The original affidavit must be mailed to the address on the top of the form.
