Miami's water comes from the shallow Biscayne Aquifer and is lime-softened at the plant. Most residents rent, many in high-rises and condos, so shared risers, water heaters and drain stacks drive a lot of local calls, along with hurricane-season flooding.

Miami plumbing questions
Where does Miami's water come from?
The Biscayne Aquifer, a shallow limestone aquifer beneath South Florida. Miami-Dade Water and Sewer treats and softens it before delivery.
Who fixes a leak in my Miami condo?
It depends on where the leak starts. Pipes serving only your unit are usually the owner's responsibility, while shared risers and stacks are usually the association's. Check your condo documents and notify the association quickly.
How do I check a Miami plumber's license?
Look up the contractor on MyFloridaLicense.com. Certified plumbing contractors (license codes starting with C) can work statewide.
What plumbing prep helps before a hurricane in Miami?
Know where your main and unit shutoffs are, keep drains clear, and after the storm watch for sewer backups and slow drains before running lots of water.
