Cut the cost and water your cooling burns, without touching uptime.

Cooling, not compute, is where a third of your energy, most of your controllable water and the second most common cause of outages all sit, and it is under growing public scrutiny in water-stressed regions.

We treat cooling water as a cost-and-risk control point, not a recurring compliance line. We cut the water and energy it consumes and harden Legionella and biofilm control to ACOP L8 and HSG274, while protecting the reliability your operation is measured on. One accountable owner, no chemistry lock-in.

Independently verified: cooling-tower bioload brought from 600 to 0 cfu/g in four days, confirmed by a UKAS-accredited laboratory.

The challenge

Your cooling water is a cost centre, a compliance risk and an outage risk at once

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.

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.

Our approach

How we cut cooling cost and risk without putting uptime in question

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, and prove the result before extending it. One accountable owner carries cost, risk and reuse together, which is the question the fragmented incumbents are never asked.

What you get

Lower cost, hardened risk, uptime protected

Cost

Cut the water your cooling consumes

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 scrutiny.

Cost

Take energy out of cooling

Reduce the energy cooling consumes, the largest overhead above the compute load, and recover energy from the water you already move through the facility.

Risk

Harden Legionella and biofilm control

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.

Risk

Protect uptime, not just compliance

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.

Cost

One owner of cost, risk and reuse

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.

Obligation

Evidence your water and carbon position

Produce the reportable water and energy data the disclosure regimes, and increasingly the planners, expect, from water and energy efficiency to mandatory water reporting.

Evidence

Validated in accredited testing on the same cooling water

The hardest part of a data centre to change, proven on a live cooling-water system.

Cooling water

A cooling-tower system brought to zero pathogens in four days

On a recurring cooling-water pathogen problem that conventional dosing had failed to fix for years, bioload fell from 600 to 0 cfu/g across every test point. Legionella, E. coli and coliforms were eliminated, confirmed by a UKAS-accredited laboratory, and held on routine maintenance dosing.

Compliance

Six of six cooling-water sites from fail to pass

Every test point on the treated cooling-water system moved from fail to pass on water-safety compliance, confirmed by a UKAS-accredited laboratory, and the operator extended the approach across the wider water network.

Water recovery

More cooling water recovered, less drawn

Running cooling water harder per cycle and recovering more of it reduces the makeup water a facility draws and the volume it discharges, the water that matters most in a stressed catchment. We quantify the recovery for your site.

Before you commit

Uptime first, compliance preserved, savings second

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.

Reliability and compliance preserved as the precondition, never the trade.
Questions answered
Will this put cooling reliability or uptime at risk?

No. We treat reliability and ACOP L8 compliance as the precondition of any change, not the trade for a saving. We prove the result on one system before extending it across the estate.

Does it keep us compliant with ACOP L8 and HSG274?

Yes. We strengthen Legionella 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.

Can you actually reduce our water use?

Yes. We recover and reuse more cooling water and run it harder per cycle, reducing the makeup water you draw and the volume you discharge, which matters most in the water-stressed regions where most UK capacity is being built. We quantify it for your site.

How do you reduce cooling energy?

Cooling is the largest energy overhead above the compute load. We reduce what it consumes and can recover energy from the water already moving through the facility. We quantify the opportunity per site rather than quote a generic figure.

We already have a water-treatment contractor we trust. Why change?

A compliance contractor owns the chemistry but not the cost, the water recovery or the energy. We own all of it as one accountable outcome, with no single-supplier lock-in, while preserving the compliance you already have.

Why do you not quote a percentage saving?

Because honest numbers in this sector are site-specific, and most published percentages are vendor marketing. We assess your cooling water and give you a figure tied to your facility, not a headline.
