How a Miami Beach Hotel Reduced Total Water Utility Costs by 20.7% | Part 3
For Miami hotels, water conservation is difficult for a simple reason: the guest experience still has to come first.
Showers need strong, usable pressure. Laundry has to run. Kitchens, pools, landscaping and housekeeping continue every day. And many properties have already installed efficient fixtures and other conservation measures.
That is what makes the documented result at The Gates Hotel South Beach especially useful.
FluidLytix reports that the Miami Beach property calculated an average 20.7% reduction in its total water utility costs after installing the Wave Valve™. The result was based on actual property utility data, not a theoretical savings model.
The case does not mean every hotel will save 20.7%. It showw why high-use hospitality properties should evaluate water efficiency at the building level, not only fixture by fixture.
A High-Use Hospitality Property in Miami Beach
The Gates Hotel South Beach operated as a 235-room hotel on Collins Avenue in Miami Beach, with a restaurant, swimming pool, laundry and other water-intensive hospitality operations. It has 235 guet rooms, one restaurant and one swimming pool.
Hotel water consumption can include:
Guest showers, faucets and toilets
Housekeeping
Laundry
Restaurants and bars
Pool operations
Landscaping and irrigation
Mechanical systems
Staff and back-of-house areas
Unlike most office buildings, hotels typically use substantial amounts of water around the clock. That makes water efficiency valuable, but only if it does not interfere with guest experience.
The Documented Result: 20.7% Lower Total Water Utility Costs
Christian Diaz, then Director of Engineering at the property, said:
“This product has been more effective than any other water savings measures we have implemented throughout the property.”
The FluidLytix installation took less than 30 minutes, causing minimal inconvenience to hotel staff or guests, and the property continued to experience strong water pressure after installation.
Water Cost Savings Are Not the Same as Gallons Saved
There is an important distinction in this case study. The documented 20.7% figure refers to water utility cost savings, not a 20.7% reduction in total gallons consumed.
That difference matters because commercial water bills can include:
Meter charges
Water consumption charges
Wastewater charges
Tiered or inclining rate structures
Other account-specific fees
The Miami-Dade Water and Sewer Department currently uses an inclining rate structure, meaning the unit price rises as consumption increases.
For a high-use hotel, reducing metered consumption can therefore influence both physical water use and the financial rate applied to that consumption. That is why FluidLytix evaluates properties using actual bills rather than assuming every gallon has the same economic value.
The Property Already Used Traditional Conservation Measures
The Gates Hotel is also a useful example because it was not starting from zero.
The hotel’s sustainability efforts include water-efficient fixtures and equipment, a linen and towel reuse program, weather-based irrigation and water-conservation staff training.
Miami-Dade itself encourages these types of measures. The County offers qualifying hotels and motels rebates for efficient toilets and other WaterSense fixtures, along with large-volume showerhead programs for eligible lodging properties.
Those traditional measures remain important.
The Wave Valve™ addresses the building from a different point in the system.
Rather than replacing individual fixtures, the device is installed on the building’s main water line and is designed to operate alongside existing conservation measures.
That makes the two approaches complementary rather than mutually exclusive.
Why Building-Level Water Efficiency Matters
A commercial property is not simply a collection of faucets and toilets.
It is a complete water-distribution system. Pressure, flow, meter technology, system configuration and demand all affect how that system operates.
For that reason, a building-level water-efficiency evaluation should consider factors including:
Meter technology. Different meter types respond differently to system conditions.
Incoming pressure. The building needs sufficient pressure to maintain acceptable fixture performance.
Consumption history. Multiple billing periods help establish normal usage and seasonal patterns.
Occupancy and activity. For hotels, water use should ideally be evaluated relative to room-nights sold rather than gallons alone.
Existing conservation measures. Low-flow fixtures, leak repair and irrigation controls should be included in the overall picture.
The Wave Valve™ is one possible layer in that broader strategy.
The Result Should Be Measured Against Building Activity
One of the most useful lessons from this case is that hotel water efficiency should not be judged only by whether total consumption falls. A hotel could reduce total water use simply because occupancy declined. That would not necessarily represent better efficiency.
A stronger measure compares water consumption with actual hotel activity.
FluidLytix’s broader technical analysis of the Gates property reports that room-nights sold increased while water consumption decreased during the comparison period, meaning water use per occupied room also improved. That type of normalization is much more meaningful for hospitality operators because it asks:
How much water are we using to produce each occupied room-night?
That turns water from a general sustainability metric into an operating-performance metric.
Rising Miami-Dade Rates Make the Case More Relevant
This case study becomes especially relevant as Miami-Dade utility costs continue to receive attention.
The current Miami-Dade Water and Sewer Department rate schedule remains the 2025–26 schedule effective October 1, 2025, and the County continues to use an inclining structure designed to encourage conservation.
Miami-Dade is also considering a proposed 6% retail water and wastewater rate adjustment effective October 1, 2026. The County Commission accepted the WASD report describing that proposal on July 21, 2026, but the official legislative record still identifies the adjustment as proposed.
For high-use hospitality properties, higher utility rates increase the financial value of avoiding unnecessary consumption. The important point is not that a particular savings percentage should be expected at every property.
It is that owners should understand the efficiency opportunity before higher rates arrive.
What Other Miami Hotels Can Learn
T
he Gates result should be treated as a property-specific case study, not a universal guarantee. But it supports several broader lessons: First, hotels can pursue water efficiency without making the guest the conservation strategy. Second, traditional fixture-level measures and building-level water management can work together.
Third, results should be verified from actual utility data. And fourth, high-use properties should evaluate water efficiency in financial terms—not simply gallons.
For hospitality owners, that means looking at consumption, water and sewer charges, occupancy, meter information and system conditions together.
Start With One Water Bill
The easiest first step is simply understanding the property’s current water profile. FluidLytix can review a recent commercial water bill, meter information and operating profile to help determine whether a hotel appears to be a reasonable candidate for deeper water-efficiency analysis.
