More than one utility may serve Aventura, so the first thing to know is which one supplies your home. According to NMB Water's 2025 report, residents of Aventura are likely served by NMB Water, which is the City of North Miami Beach. Miami-Dade Water and Sewer Department (WASD) serves a large part of the county as well. Your water bill will tell you who your utility is. The two utilities treat water differently, so what one reports does not apply to the other. We're starting in Miami-Dade County, and whether we can reach your address depends on which plumbers have confirmed availability there. You call and send a few photos of where the water comes in or of your open sink cabinet. We give you one written price for a named system. A local plumber handles the install.
What each utility reports
| Miami-Dade (WASD) | NMB Water | |
|---|---|---|

| Biscayne Aquifer depth | Just below the land surface in South Florida, per WASD's 2025 report | Approximately 10 to 200 feet below ground, composed of porous limestone, per NMB Water's 2025 report |
| Floridan Aquifer treatment | The Hialeah Reverse Osmosis Water Treatment Plant treats brackish water from the Upper Floridan Aquifer at about 1,400 feet deep, per WASD's 2025 report | Water from the Floridan Aquifer, drawn from about 1,250 feet, is treated by reverse osmosis because it is brackish, per NMB Water's 2025 report |

| Treatment plant | Alexander Orr Jr., John E. Preston, Hialeah, five South Dade plants, and the Hialeah Reverse Osmosis Water Treatment Plant, per WASD's 2025 report | Norwood Water Treatment Plant, operating for more than 70 years, per NMB Water's 2025 report |

What the reports tell you and what they don't
Both utilities publish annual water quality reports, and both are worth reading before you decide anything. NMB Water's 2025 report covers data collected from January 1, 2025 through December 31, 2025. WASD's 2025 report covers the same calendar period. Neither report we read prints a finished-water hardness figure. NMB Water's 2025 report says its Biscayne Aquifer water goes through lime softening, but it does not give a finished-water hardness number. If that figure matters to you, call the utility and ask. For NMB Water, the contact address listed in its 2025 report is 17050 NE 19th Avenue, North Miami Beach, FL 33162. A report tells you what the utility measured at the point it delivers water. What comes out of a specific fixture in your home also depends on your own plumbing. Those are two different things. A report alone won't settle the question.
Choosing a system for your home
The choice between a whole-house filter and an under-sink reverse osmosis system is mostly about where in the house you want treated water and what your plumbing allows, not about which utility supplies you. A whole-house system is installed where the main line enters the house and serves the fixtures connected after it. An under-sink RO system sits in one cabinet and serves one or two faucets. If you want to think through the difference, whole-house filter or reverse osmosis: how to choose lays out the trade-offs plainly. Some homeowners also wonder about water softeners. water softener or water filter: what's the difference? gives useful background if you're weighing both.
