Cooling Tower Vapor Recovery
Stop Sending Your Water to the Sky
Every hour your cooling tower runs, treated water you already paid for evaporates away. AquraIQ recovers that vapor and returns it as clean water — measured, verified, and provable.
The Need
Cooling is the largest single use of water at most industrial facilities. At thermoelectric power plants it accounts for 41% of all freshwater withdrawn in the United States, with roughly 876 billion gallons a year lost to cooling tower evaporation. A single hyperscale data center can evaporate up to 5 million gallons a day.
That water was already treated and already paid for. And where supply is constrained, losing it isn't just a cost line — it's what limits your permits, your reporting, and your ability to expand.

What Recovery Gives You
Lower makeup water demand
Recovered water (vapor) returns directly to your system, reducing the volume you have to buy and treat.
Lower treatment and discharge cost
Returning pure water to the loop dilutes dissolved solids, raising cycles of concentration and shrinking blowdown volume.
Permit headroom
In constrained regions, water you recover on site doesn't draw against your withdrawal allocation.
Reporting you can defend
Every gallon is measured and cryptographically signed at the sensor — not estimated in a spreadsheet.
A new revenue line
Verified recovery can be issued as tradable Water Credits, turning a cost center into an asset.
Zero disruption
Nothing on the tower is modified and no shutdown is required. Your cooling system runs exactly as before.
GALLONS PER DAY, PER TOWER CELL
Capacity scales with your tower. Each cell has its own exhaust fan and its own recoverable plume, so a multi-cell tower multiplies what a site can recover. Actual output depends on fan capacity, allowable back-pressure, load profile, and climate — your site study gives you the number for your tower.
What We Install
An insulated stainless duct assembly mounts to the outside of your tower, draws saturated exhaust into an atmospheric water harvesting unit, and captures the vapor back into clean water.
Nothing on the cooling tower is modified. No cutting. No penetration of the housing. No change to the fill, the fan, or the water loop. The assembly attaches to the exterior panels with adjustable brackets and standard HVAC fittings, and can be removed or repositioned without a trace. If a configuration would compromise thermal performance, we don't propose it.
Validated in the Field, Not Modeled
The capture method was validated at AzAWH at ASU on an operating cooling tower, with continuous instrumented measurement across a full desert year — through peak summer heat and winter conditions alike.
The quality of the recovered water exceeds that of reverse osmosis (RO) water.
Why It Works Where Other Approaches Struggle
Some capture methods collect droplets that have already condensed in the plume. That works where the surrounding air is cool and humid enough for a plume to form.
In hot, arid climates the plume never becomes droplets — it disperses as vapor. That is precisely where water is scarcest and recovery matters most.
AquraIQ condenses the vapor itself, at the exhaust, where humidity stays above 90% year-round no matter what the outside air is doing.
Three Things That Change the Economics
Zero reject
Every gallon captured becomes usable water. Reverse osmosis discards 20–65% of its feed as brine. We discard nothing.
Purer than typical RO permeate
Lower conductivity, lower TOC and dissolved ions.
Runs on heat you already waste
At power plants and data centers, low-grade waste heat can drive the harvesting cycle instead of purchased electricity.
Straight Answers
This won't replace your water supply
Recovery captures a meaningful share of evaporative loss, not all of it. Anyone promising otherwise is selling something that doesn't exist.
Capacity is set by your tower
Exhaust fan capacity and allowable back-pressure determine how much you can recover — not your water bill. That number comes from a site study.
Dry cooling means no project
No plume, nothing to recover. We'll tell you on the first call rather than waste your time.
How It Starts
Qualify
One conversation. Tower type, number of cells, operating hours, water cost. We tell you whether it's worth pursuing.
Site study
We model realistic recovery for your tower and your climate, with every assumption written down.
Install
Non-invasive, no shutdown required. Baseline is measured before recovery begins, so your gains are provable.
Verify
Continuous signed measurement feeds your internal reporting, your permit documentation, and your Water Credits.
Tell us your tower type. We'll tell you if it's worth your time.
