Data centre water treatment is the management of cooling-water chemistry, recovery and disinfection across cooling towers and condenser-water loops, so a facility uses less water and energy, keeps Legionella and biofilm under compliant control, and protects uptime. The strongest approaches cut makeup water and cost while evidencing every result independently.
In a data centre the overriding fear is anything that touches uptime, so cooling water is run by an incumbent regime no one revisits, even as its cost and its risk rise.
Cooling, not the servers, is where the controllable cost sits. At a typical efficiency, around a third of total facility energy is overhead, dominated by cooling, and cooling failure is the second most common cause of impactful outages, more than half of which now cost over 100,000 dollars each.
Water has become the public problem. Most new UK capacity is planned for the most water-stressed parts of the country, and 84% of water-intensive proposed developments sit in areas already short of water or projected to be by 2040. Operators are increasingly asked to justify their water draw at the planning stage, in public, and to report it under tightening disclosure regimes.
Wet cooling towers sit in the highest Legionella risk category by design, under ACOP L8 and HSG274. Yet the water-treatment regime is usually an annual compliance contract no one wants to touch, because changing it feels like risking uptime, so the cost and the water keep climbing and no one is asked to own all three together.
We make cooling water a single, accountable control point for cost, compliance and reliability, and we de-risk the change before we make it.
We reduce the water and energy your cooling consumes, by recovering and reusing more of it and running it harder per cycle, and we strengthen Legionella and biofilm control to ACOP L8 and HSG274 rather than weaken it. Because we are technology-agnostic, there is no single-supplier chemistry lock-in, and the same water you already move can be a source of recovered energy.
Uptime comes first. We preserve or improve cooling reliability and compliance as the precondition, not the trade, work on the live system without taking it offline, and prove the result before extending it. Every result is verified by an independent or accredited laboratory, so it stands up to an asset review, a planning question or a water disclosure. One accountable owner carries cost, risk and reuse together, which is the question the fragmented incumbents are never asked.
Recover and reuse more cooling water and run it harder per cycle, so the makeup water and the bill both fall, in the water-stressed regions where draw is now under public scrutiny.
Reduce the energy cooling consumes, the largest overhead above the compute load, and recover energy from the water you already move through the facility.
Bring cooling-tower and condenser-water pathogen and biofilm risk under reliable, compliant control to ACOP L8 and HSG274, the highest-risk water on the site.
Cooling failure is a top cause of outages. We strengthen reliability and control as the precondition of any change, never the trade for a saving.
Replace the compliance contractor, the cooling vendor and the energy bolt-on with a single accountable owner of the whole cooling-water outcome, with no chemistry lock-in.
Produce the reportable water and energy data the disclosure regimes, and increasingly the planners, expect, from water and energy efficiency to mandatory water reporting.
The hardest part of a data centre to change, proven on a live cooling-water system.
The UK environmental and safety duties that commonly reach data centre water treatment. Open any one for what it requires, the deadlines, what is at stake, and how to evidence control. Every entry is sourced.
The decisive question in any data centre is the right one: will this put availability at risk? If the answer is anything but a clear no, nothing else matters.
So we start there. We preserve or improve cooling reliability and ACOP L8 compliance as the precondition of any change, prove it on one system before extending, and only then bank the water and energy savings on top. We are technology-agnostic, so there is no single-supplier chemistry lock-in, and you keep one accountable owner of cost, risk and reuse rather than a compliance contractor who owns the chemistry but not the cost. We lead with the engineering outcome, not a headline percentage your team would rightly distrust.
It is the management of cooling-water chemistry, recovery and disinfection across cooling towers and condenser-water loops, so a facility uses less water and energy, keeps Legionella and biofilm under compliant control, and protects uptime. The strongest approaches cut makeup water and cost while evidencing every result independently.
Water usage effectiveness improves when you recover and reuse more cooling water and run it harder per cycle, so the makeup water you draw and the volume you discharge both fall. That matters most in the water-stressed regions where most UK capacity is being built. We quantify the reduction for your site rather than quote a generic figure.
Wet cooling towers sit in the highest Legionella risk category by design, so control must be hardened, not relaxed. We strengthen pathogen and biofilm control on cooling towers and condenser water to ACOP L8 and HSG274, and produce the verified evidence your duty-holder and inspections require.
Cycles of concentration describe how many times cooling water is recirculated and evaporated before it is bled off as blowdown. Running more cycles means less makeup water and less discharge, but it concentrates the chemistry, so it only saves water safely when scaling, corrosion and biofilm stay under reliable control. We set the safe operating point for your system.
Larger facilities face tightening disclosure on water and energy performance, including water usage effectiveness, energy efficiency and overall water draw, alongside planning-stage scrutiny of water use. We produce the reportable water and energy data those regimes and planners expect, so the position you disclose is measured, not estimated.
Yes. Cooling failure is a top cause of impactful outages, so we preserve or improve reliability and ACOP L8 compliance as the precondition of any change, prove it on one system before extending, and only then bank the water and energy savings on top.
Yes. On a live cooling-water system, bioload was brought from 600 to 0 cfu/g in four days and six of six test sites moved from fail to pass, all confirmed by a UKAS-accredited laboratory. We do not quote vendor percentages; we assess your cooling water and give you a figure tied to your facility.
Tell us where cooling cost, water draw or compliance risk sits hardest. We will assess one system and show you the outcome, with uptime protected, before you commit.
Tell us the cost, the risk or the obligation you are facing. A senior member of our team will respond, in confidence, with how we would help.
