Miami-Dade Water Bill Adjustments, Credits and Leak Review
If your bill suddenly increases, first check whether usage changed because of irrigation, a running toilet, a private leak, a pool fill, a broken pipe or a billing-period change. If you believe the bill needs formal review, use Miami-Dade’s Water Bill Adjustments and Credits resource.
When adjustment review may help
Adjustment review may be relevant when you had a concealed leak, unusually high usage, corrected plumbing issue or billing concern that needs Customer Relations review.
Where to send adjustment-related mail
Miami-Dade lists Water and Sewer Department, Attention: Customer Relations Unit, 3071 SW 38th Ave., Miami FL 33146-1520 for adjustment and credit resources.
| High-bill clue | Possible cause | What to do first |
|---|---|---|
| Bill doubled or tripled | Running toilet, irrigation issue, underground leak or pool fill. | Check usage history in your online account and inspect common leak points. |
| Meter movement when water is off | Private leak inside or outside the home. | Document the issue, repair it, keep receipts and contact Customer Relations if seeking review. |
| Payment not reflected | Processing delay, wrong account, mail delay or confirmation issue. | Use payment receipt and call 305-665-7477 for account-specific review. |
| Emergency leak outside property | Public water/sewer emergency or main issue. | Call the 24-hour emergency line at 305-274-9272. |
