Your Data Center Is Paying for Cooling Water It Never Used — on Every Billing Cycle
Cooling tower makeup water is the single largest water consumer in most data centers — and the pressure cycling of cooling systems creates exactly the conditions that cause water meters to over-read. The FCD (Flow Conditioning Device) corrects that without touching a single server rack or cooling system.

1-hour operational impact — all systems unchanged
Direct answer: Municipal water meters register volume, not composition — air and turbulence moving through the meter get counted as billable water even though nothing was actually delivered. In a data center, cooling tower level calls and chiller makeup draw create exactly the conditions that cause this over-registration, every operating day. Because sewer charges are typically calculated from metered water intake, the same over-read inflates both bills at once. The Flow Conditioning Device (FCD) corrects this at the meter — with no change to existing operations or equipment — delivering a 5–30% average water and sewer bill reduction (46% highest documented), about a 1-hour install, and 90% of customers reaching full ROI in under 12 months.

Data Center Cooling Water Is Among the Most Metered and Most Over-Read in Any Commercial Facility
Data centers are defined by their water intensity. Cooling tower makeup water, chiller systems, and free cooling loops run continuously — 24 hours a day, 365 days a year — to maintain the precise temperature conditions that protect server infrastructure. That continuous, high-volume, variable-demand water consumption creates persistent air entrainment and turbulent flow conditions at the meter. Your meter registers more than was actually delivered. You pay for it on the water bill — and again on the sewer bill, since sewer is calculated from metered consumption.
The FCD installs immediately after your water meter and creates accurate measurement conditions at that connection. Cooling tower performance is unchanged. Chiller system operation is unchanged. Server room temperature management is unchanged. Power Usage Effectiveness (PUE) and Water Usage Effectiveness (WUE) metrics both improve on the next billing cycle — because the metered water baseline is now accurate.
Signs Your Building May Be Over-Billed
These are the most common indicators that your water meter is
registering more than your facility actually uses.
Cooling water consumption higher than system design predicts
Metered makeup water volume that exceeds cooling tower basin calculations and evaporation rate models — a reliable indicator of meter over-reading rather than actual system inefficiency.
WUE metric above industry benchmarks
If your Water Usage Effectiveness is above 1.8 L/kWh for older facilities or 1.2 L/kWh for newer ones, meter over-reading may be contributing to an inflated baseline.
Water bills rising without IT load increases
Metered consumption growing independently of server capacity, power draw, or cooling demand — a consistent sign of meter over-reading.
Water balance does not reconcile
Cooling tower consumption tracking that does not reconcile between metered input and evaporation, blowdown, and drift calculations.
Sewer charges tracking water bills upward
Since sewer is billed from metered consumption, any over-reading automatically inflates both bills simultaneously every cycle.
Water costs treated as fixed infrastructure expense
Accepting utility bills as non-negotiable when they contain a correctable meter inaccuracy — common in data center operations where utilities are treated as fixed OPEX.
Cooling System Performance, Server Uptime, and PUE Are Completely Unchanged
The FCD installs on the main water line immediately after the water meter — before your cooling tower makeup water distribution system. It does not modify any cooling system component, chiller connection, or server room infrastructure. Cooling tower basin levels are maintained identically. Chiller performance is unchanged. Server room temperature and humidity are unchanged. There is no operational downtime required beyond the brief water shutoff during installation.
For data centers with multiple cooling loops and multiple metered connections, the FCD installs independently at each metered point. Each installation produces its own measurable bill reduction. Your WUE metric improves on the next billing cycle because the metered fresh water input figure is now accurate — not because you changed anything about how your cooling system operates.
Where Water Over-Charges Hit Your Operation
Meter over-reading creates budget pressure, operational reporting problems, and sustainability challenges — all from the same correctable root cause at the meter.
Finance & Colocation
- Water and sewer costs rising without corresponding IT load increases

Common Questions — FCD Data Centers
How do I estimate savings for our facility?
Will the FCD affect cooling tower performance or server room temperature?
No — negligible pressure loss is a fundamental design characteristic of the FCD. The device installs on the main water line after the meter and creates laminar flow without meaningfully restricting it. Cooling tower makeup water delivery pressure is completely unchanged. All cooling system performance parameters are unaffected. The device installs on the main water line after the meter and creates laminar flow without restricting it. Cooling tower makeup water delivery pressure is completely unchanged. All cooling system performance parameters are unaffected.
How does this affect our WUE metric and ESG reporting?
We have multiple cooling tower connections — how does that work?
