NMB Water, the City of North Miami Beach's utility, is the one that delivers water to homes here. WASD does not serve North Miami Beach homes directly; instead, according to NMB Water's own 2025 report, NMB Water provides wholesale water to Miami-Dade County and other local communities. If you are thinking about adding a whole-house filter or an under-sink reverse osmosis system, knowing where your water comes from is a reasonable place to start. We're working across Miami-Dade County, and North Miami Beach is part of that area. You call us, send a few photos, and get one written price for a named system. A local plumber does the install.
What to do before you call
Confirm your utility
Your last water bill will show which utility serves you. According to the NMB Water 2025 report, that utility also serves customers in Aventura, Sunny Isles Beach, Miami Gardens, and Golden Beach. One pocket of addresses near NE 163 Street to NE 181 Street, between NE 6 Avenue and NE 15 Avenue, receives NMB Water-produced water delivered through WASD lines, according to the WASD 2025 report.
Read your annual water quality report
NMB Water's 2025 report covers data from January 1, 2025 through December 31, 2025. It lists what the utility tested for and what it found. Our guide on how to read your utility's annual water report can walk you through it.
Think about where you want filtered water
A whole-house system is installed where the main line enters the home and serves the fixtures connected after it. An under-sink reverse osmosis system serves one point, usually the kitchen sink. Our guide on whole-house filter or reverse osmosis: how to choose walks through the difference.
Check whether you are on city water
We are starting with homes on city water. If you are on a private well, tell us when you call and we will say honestly whether we can help yet.
Take a photo of your water entry point or under-sink cabinet
When you call, we ask for a few photos so we can give you one written price for a named system. No one comes to your home to sell you anything before the install.
Consider whether a softener is part of what you want
NMB Water's 2025 report says water from the Biscayne Aquifer goes through lime softening and/or nanofiltration before it reaches your tap. If you are wondering whether a softener still makes sense on top of that, our water softener or water filter: what's the difference page explains what each one does. We are not selling softeners yet, but that page should help you sort it out.
Contact us when you are ready
You can reach us through our contact page. We will go over your photos, tell you which systems fit, and give you a price in writing before anything is scheduled.
Where North Miami Beach water comes from
The NMB Water 2025 report says the Norwood Water Treatment Plant has been owned and run by the city for more than 70 years. The utility pulls groundwater from two aquifers. The first is the Biscayne Aquifer, which sits roughly 10 to 200 feet below ground and is made of porous limestone recharged by rainfall. The second is the deeper Floridan Aquifer, reached by wells going down to about 1,250 feet. Water from the Biscayne Aquifer is treated by lime softening and/or nanofiltration. Water from the Floridan Aquifer is brackish, so the utility runs it through reverse osmosis before it enters the distribution system. The South Florida Water Management District permits NMB Water to draw up to 38.38 million gallons per day from the Biscayne Aquifer. The utility also holds a permitted production capacity of up to 41 million gallons per day across both aquifer sources.
