At Dantek Environmental Services, we know that managing water safety is one of the most complex and critical tasks for facilities teams. Legionella prevention requires constant vigilance, and with today’s estates generating huge volumes of data, the challenge is no longer about collecting information—it’s about making sense of it.

This is where artificial intelligence (AI) makes a real difference. By connecting datasets, spotting trends, and guiding targeted interventions, AI can transform how building managers tackle Legionella risk—saving time, reducing costs, and improving compliance.

What Data Can AI Use?

Most estates already have the raw ingredients. Typical sources include:

• Electronic logbooks – temperature logs, flushing and service records
• Sampling results – direct from lab or LIMS systems (often buried within reports)
• Operational data – dataloggers, water meters, chlorine dioxide generators, BMS outputs

By consolidating these, AI can build a live picture of water system behaviour, including demand, residuals, temperature patterns, and compliance activity.

Why AI Adds Value

Unlike manual analysis, AI can:

• Overlay disparate datasets in seconds
• Generate clear outputs such as heat maps, rolling averages, and anomaly alerts
• Automate recurring analysis for consistent month-on-month reporting

For facilities managers, this means:

• Faster root-cause analysis – identifying where risks are emerging
• Better prioritisation – targeting the risers, wards, or outlets that matter most
• Smarter investment – building strong cases for focused interventions instead of costly estate-wide measures

A Real-World Example

In one care-home estate, Dantek combined water-meter logging, chlorine-dioxide dosing history, technician entries from an electronic logbook, and laboratory results—then added operational context such as the number of residents and on-site catering arrangements. AI analysis revealed oversized systems and low-use zones, causing stagnation.

The solution was a targeted plan:

• Focused flushing on the high-priority areas
• Adjusting chlorine dioxide dosing strategy
• Installing point-of-use filters at high-risk outlets
• Implementing a focused sampling programme

The outcome? Reduced Legionella activity, improved compliance, and achieved significant time and cost savings.

How to put AI into practice?

1. Start with a question – e.g. “Are low-use wings driving persistent positives?”
2. Consolidate existing data – align logs, sampling records, and operational data on a common timeline
3. Baseline and clean – standardise units, tag outlets, and tidy inputs
4. Run targeted analyses – using anomaly detection, correlation scanning, and usage profiling
5. Translate insights into actions – flushing schedules, disinfection adjustments, sampling plans
6. Close the loop – automate reporting and create a clear dashboard for your team

Guardrails for Responsible AI Use

While AI is powerful, it’s not a replacement for experienced water hygiene professionals.

• Human oversight is essential – only trained personnel can confirm physical issues such as dead-legs or valve imbalances
• Data governance matters – manage access, encrypt sensitive information, and use secure platforms
• Context is key – AI insights should always be cross-checked against on-site knowledge

What Good Looks Like

Facilities teams using AI effectively achieve:

• Clarity – simple visuals and plain-English outputs
• Consistency – scheduled analyses with repeatable KPIs
• Efficiency – targeted interventions replacing blanket measures
• Safety – a human-in-the-loop approach for decision-making

Bottom Line

AI is not a silver bullet, but it is a powerful ally in Legionella control. By combining existing data with professional expertise, you can:

• Reduce risk and demonstrate compliance
• Focus resources where they have the most impact
• Deliver safer, more efficient building management
