Water Filter Installation in Miami-Dade County, FL

Miami-Dade is not one water system. Depending on where you live, your water may come from Miami-Dade Water and Sewer Department (WASD), the City of Hialeah, NMB Water, the City of North Miami, the City of Miami Beach, or the City of Homestead, among others. The name on your water bill is the fastest way to know which utility is yours. Each publishes its own annual water quality report, and each one is worth reading before you decide what, if anything, you want to filter. We're starting in Miami-Dade, Broward, and Palm Beach counties. If you're on city water and want to talk through your options, reach out and we'll walk you through it.

Which utility likely serves your area

• Miami-Dade Water and Sewer Department (WASD)

  WASD is the largest water supplier in the county. According to its 2025 report, it delivers water to more than 2.8 million people across most of Miami-Dade every day. The water comes mainly from the Biscayne Aquifer, with a smaller number of wells drawing from the Floridan Aquifer. Three regional treatment plants, Alexander Orr Jr., John E. Preston, and Hialeah, along with five smaller South Dade plants, treat that water and send it into a shared distribution system that covers most of the county.

• City of Hialeah and NMB Water (City of North Miami Beach)

  Hialeah runs its own water and sewer system through its Department of Public Works. That system includes at least one reverse osmosis plant as part of treatment, according to the city's 2026 report covering 2025 data. NMB Water is a separate regional utility. It serves roughly 180,000 people, including customers in Aventura, Sunny Isles Beach, Miami Gardens, and Golden Beach, and also sells water wholesale to Miami-Dade County, according to its 2025 report. These two utilities are not the same. A fact from one does not apply to the other.

• City of North Miami and City of Miami Beach

  North Miami runs its own water system drawing from the Biscayne Aquifer through eight service wells and distributing treated water across more than 300 miles of lines to over 90,000 people, including parts of unincorporated Miami-Dade, Miami Shores, and Biscayne Park, according to its 2025 report. Miami Beach is different again: the city buys its water wholesale from WASD and distributes it to roughly 10,000 customers across its more than seven-square-mile island, according to the city's 2025 report.

• City of Homestead

  Homestead pulls its drinking water from the Biscayne Aquifer at two well fields, Wittkop Park and Harris Field, then holds treated water in elevated towers before it reaches your tap, according to its 2025 report. The aquifer sits anywhere from a few feet to roughly 200 feet below ground in that area. If you are in Homestead, the city's report is the first place to look at what is in your supply.

How to find and read your utility's report

Each utility in Miami-Dade publishes an annual water quality report, sometimes called a Consumer Confidence Report. These are public documents. Reading them is straightforward once you know what to look for. WASD's 2025 report is available through the county at the link above. Hialeah's 2026 report covering 2025 data is posted at hialeahfl.gov. Questions about it go to the Division of Water and Sewer at 305-556-3800 ext. 2542. NMB Water's 2025 report is on the city's document center. For water quality questions about WASD service, the Alexander Orr Jr. plant zone can be reached at 786-552-4181.

We'd rather you go in informed than sell you something you don't need.

Whole-house filters and under-sink RO systems: what to consider

Once you've read your report, the next question is what type of system, if any, makes sense for your home. A whole-house water filter sits on the main supply line and treats water going to the fixtures inside the house. An under-sink reverse osmosis system treats water at a single point, typically the kitchen sink, for drinking and cooking. These two options solve different things, and in some cases neither is the right answer. Our guide on whole-house filter or reverse osmosis: how to choose walks through the difference without pushing you toward either one. Be skeptical of any broad claim about what a system removes, including from us. Performance depends on the specific model and its testing. If a claim sounds specific, ask for the certification listing and check that it covers the full system. We're also not launching softeners as part of our current offer, but if you want to understand how they compare to filters, our softener vs. filter guide covers it. You can also visit the water softeners page for more context.

How we work in Miami-Dade

We sell by phone. There's no in-home salesperson and no showroom. You call, send a few photos of where the water comes in or of your open sink cabinet, and get one written price for a named system. A local, independent plumber does the install. We manage the job. We only give you an install date once that plumber has confirmed it. We'd rather be honest about timing than promise something we can't deliver. We're starting with homes on city water in Miami-Dade. If you're on a private well, tell us when you call and we'll be straight with you about whether we can help yet. Coverage depends on which plumbers we have confirmed in your part of the county. We're new, so our customer list is still small. What we have is a price in writing. See how it works and how pricing works for more detail, or browse all our service areas. When you're ready, reach out and we'll take it from there.
