If you manage a hotel, apartment community, restaurant, office building or other commercial property in Miami-Dade, you’ve probably noticed something about your water bill:
It doesn’t seem to be getting any cheaper.
We spend a lot of time at FluidLytix looking at commercial water bills. And one thing
we’ve learned is that many property owners know what they’re paying each month, but they don’t necessarily know why they’re paying it—or how much the rate structure itself can affect the final bill.
This is the first article in our 5-part Miami-Dade Commercial Water Cost Series. Over the next several days, we’ll break down current water and sewer rates, proposed increases, real Miami-area results, and practical ways commercial properties can reduce costs.
Miami-Dade commercial water pricing isn’t simply a flat price per gallon. The County uses an inclining rate structure, which means the price per unit of water increases as consumption moves into higher usage tiers.
For high-use properties, that matters a lot.
So we thought it would be helpful to break down the current rates in plain English.
First: How Does Miami-Dade Commercial Water Pricing Work?
A typical commercial water bill includes two basic pieces:
A meter charge, based largely on the size of the property's water meter.
A consumption charge, based on how much water the property actually uses.
Miami-Dade measures water consumption in CCF, which stands for one hundred cubic feet.
1 CCF = 748 gallons.
Where things get interesting is that the price per CCF changes depending on how much water the property uses.
As consumption rises, the property moves through increasingly expensive rate tiers.
That means a gallon of water used late in the billing cycle can effectively cost considerably more than a gallon used in the lowest tier. For a large hotel, multifamily community or other high-consumption property, those higher tiers can add up quickly.
Let's Look at a Real Example
We'll use a 2-inch commercial water meter because it makes the structure fairly easy to see. Under Miami-Dade's current FY 2025–26 schedule, a 2-inch non-residential meter billed monthly has a meter charge of:
$54.11 per month
Then the water consumption rates are:
Monthly Water Use | Rate |
0–24 CCF | $0.5109 per CCF |
25–56 CCF | $4.4141 per CCF |
57–136 CCF | $5.9254 per CCF |
137+ CCF | $10.4299 per CCF |
Here's the part we want property owners to notice: The highest tier is more than 20 times the per-unit price of the first tier. That doesn't mean every gallon on the property suddenly costs $10.4299 per CCF once you cross the threshold. The tiers apply incrementally.
But it does mean that additional consumption at a high-use property can become very expensive. And that is why water efficiency can have more financial value at a large commercial property than simply multiplying gallons saved by one flat water rate.
Quarterly Billing Works the Same Way. Some commercial accounts are billed quarterly. For that same 2-inch meter, Miami-Dade's current quarterly meter charge is:
$162.33
The quarterly consumption tiers are:
0–72 CCF: $0.5109 per CCF
73–168 CCF: $4.4141 per CCF
169–408 CCF: $5.9254 per CCF
409+ CCF: $10.4299 per CCF
The billing period changes the usage thresholds, but the underlying idea is the same:
Higher consumption moves into higher-priced tiers.
And Then There's the Sewer Side of the Bill
This is the part of the conversation that sometimes gets overlooked.
Reducing water consumption can matter beyond the water charge itself because many commercial properties also have wastewater charges tied to water usage.
For a 2-inch non-residential meter billed monthly, Miami-Dade's FY 2025–26 wastewater schedule currently includes:
$74.64 monthly base facility charge
Plus:
0–3 CCF: $1.7653 per CCF
4+ CCF: $8.3585 per CCF
So when we're reviewing a commercial property's opportunity for savings, we don't want to look at just one line on the bill. We want to understand the whole water utility picture. Where wastewater charges are based on metered water consumption, lower water usage may also result in lower related wastewater charges. Every property is different, which is why we prefer to look at the actual bill rather than make assumptions.
Why This Matters Especially for Hotels, Multifamily and Restaurants
Some buildings simply use a lot of water because of what happens inside them every day.
A hotel may have hundreds of guest rooms, restaurants, laundry facilities, pools, landscaping and public restrooms.
A multifamily property might have hundreds of residents sharing one master-metered water system.
Restaurants use water continuously for cooking, cleaning, dishwashing, sanitation and restrooms.
Healthcare, office, retail and industrial properties each have their own patterns.
Water use is part of operating the building.
The challenge is separating the water the property genuinely needs from consumption that may be reduced without negatively affecting the people using the building. That's where we think the conversation gets much more interesting than simply telling everybody to use less water.
You Can't Control the Utility Rate. You Can Look at Consumption.
Property owners don't get to decide what Miami-Dade charges for water, but consumption is another story. That's why one of the first things we ask a prospective FluidLytix customer for is surprisingly simple:
Send us a water bill. We can learn quite a bit from it. The bill can tell us about meter size, consumption, utility charges and usage patterns. From there, we can determine whether it makes sense to take a closer look at the property.
FluidLytix's patented WAVE Valve™ is installed on the main water line and is designed to help reduce metered water consumption while working with the property's existing plumbing and fixtures.
It's not a program where we come in and replace every toilet, faucet or showerhead.
And we don't assume every property is a candidate. We evaluate the property first.
We've Already Seen What This Can Mean in Miami Beach
One reason we're especially interested in helping Miami-Dade commercial properties is that we already have real operating experience here.
At The Gates Hotel Miami Beach, FluidLytix documented an average:
20.7%
reduction in total water utility costs.
For us, that's much more meaningful than simply showing someone a theoretical calculation. It's an operating hotel with real guests, real water bills and real-world conditions. And that is how we prefer to talk about water efficiency—with actual property results whenever possible.
Are Miami-Dade Rates Going Up Again?
This is something we're watching closely. Miami-Dade is currently considering a 6% retail water and wastewater rate adjustment for FY 2026–27, with a proposed effective date of October 1, 2026. As of August 2026, that increase should still be described as proposed, not as an already-effective rate. We'll update this article when new official rates take effect.
And we'll be writing separately about the proposed increase because we think commercial property owners should understand what it could mean for future operating budgets.
Our Advice: Don't Wait for the Next Rate Increase to Look at Your Bill. We aren't suggesting that every commercial property in Miami-Dade has a 20% savings opportunity. Properties are different, consumption is different, pressure, occupancy, plumbing configurations, utility billing and operating patterns are different.
If you're spending a significant amount on water and sewer every month, it's worth understanding whether part of that cost can be reduced. That's why we're happy to start with something very simple.
We'll take a look at it and help you understand whether there appears to be a meaningful opportunity. No need to decipher every CCF tier yourself. Send Us Your Water Bill.
