Legionella Monitoring Software

The dashboard.
Where data becomes action.
And record.

Sensors gather readings; software turns them into decisions. The AQUAIOT cloud dashboard sets thresholds, raises alerts, routes them by role, and holds the exportable record, so the data actually drives what happens next.

The AQUAIOT Solution

Set thresholds.
Route alerts.
Export records.

The software layer is where monitoring becomes management. The AQUAIOT cloud dashboard checks every reading against your thresholds, sends alerts to the right people, and keeps a tamper-evident record ready to export.

Thresholds and trendlines, set control limits per asset and watch temperatures as live trendlines, so drift is visible before it becomes a breach.
Role-based alerts and routing, SMS, email, and app notifications sent to the right person, with escalation if the first responder does not act.
Records and integration, tamper-evident exportable logs, plus an API into BMS, CAFM, and SCADA, so the software fits your wider estate tools.

How It Works

Three steps to continuous L8 compliance

Step 01

Monitor

AQUAIOT sensors are deployed at tanks, loops, calorifiers, and sentinel outlets. Temperature is profiled continuously, every reading timestamped and logged to the cloud over secure cellular or LoRaWAN telemetry.

Step 02

Alert

When temperatures drift outside HSE L8 thresholds, or when a scheduled flush is missed, AQUAIOT triggers an immediate alert via SMS, email, or app, with role-based escalation rules for your estates team.

Step 03

Record

Every reading, alert, and action is captured in tamper-evident audit logs. Records are exportable on demand and integrate with CAFM, BMS, and AIMS systems, so audit preparation is minutes, not days.

Capabilities

Everything your L8 programme needs

Purpose-built for estates, facilities, and compliance teams managing water systems across single or multiple sites.

Real-time temperature profiling

Continuous monitoring at tanks, calorifiers, loops, and sentinel outlets. Every reading timestamped and stored, never a gap in your record.

HSE L8 threshold alerting

Thresholds checked against HSE L8 and ACoP guidance. Alerts fired immediately when cold water exceeds 20C or hot water falls below 50C at point of use.

Missed-flush detection

AQUAIOT detects when scheduled flushing routines are not completed and generates an automatic alert, so no event is undocumented.

Tamper-evident audit trails

Every reading and action is logged with a secure, unalterable timestamp. Exportable records ready for audit, inspection, or HSE enquiry at any time.

API / BMS / CAFM integration

Open and interoperable. AQUAIOT connects to your existing SCADA, AIMS, CAFM, and BMS platforms via RS485/Modbus or REST API, no lock-in.

Retrofit-friendly deployment

Non-invasive sensors designed for live environments. No pipe cutting, no shutdown. AQUAIOT engineers handle site survey, installation, and commissioning.

Who It’s For

Built for the teams responsible

Housing Providers

Protect tenants. Prove compliance.

Housing associations and registered providers carry a statutory duty of care over water systems in their properties. Manual L8 management across multiple sites is operationally fragile, and increasingly under scrutiny.

  • Continuous monitoring across all properties, single dashboard view
  • Automatic alerts when vacant properties develop risk conditions
  • Audit-ready records for insurance, regulatory, and legal purposes
  • CAFM and property management system integration
NHS & Public Sector

Clinical-grade water safety. Without the admin burden.

NHS Estates and public sector facilities operate under HTM 04-01 and HSE L8 obligations. The complexity of large estates, multiple buildings, and dense pipework makes manual monitoring inadequate at scale.

  • Dense outlet coverage across clinical environments
  • Real-time temperature monitoring at thermostatic mixing valves and outlets
  • Integration with existing BMS and CAFM infrastructure
  • Automated compliance records compatible with HTM 04-01 requirements
Facilities & Estates

Less time on rounds. More time on management.

Commercial estates, universities, leisure facilities, and large offices face the same challenge: manual L8 inspection rounds are resource-intensive and provide only a snapshot. Automation changes that calculus entirely.

  • Replace labour-intensive manual rounds with automated monitoring
  • Role-based dashboard access for estates managers, deputies, and contractors
  • Reduce reactive call-outs, detect issues before they escalate
  • On-demand compliance reports for building managers and insurers
Defence & Secure Sites

Secure by design. Compliant by default.

Defence estates, MoD sites, and government facilities carry the same L8 duty of care as any other property, often across aging, complex pipework that is hard to reach and harder to document. Manual rounds leave gaps AQUAIOT closes permanently.

  • Encrypted telemetry, cellular and LoRaWAN with secure payload transmission
  • Tamper-evident immutable logs with timestamps and user actions
  • Role-based dashboard access, right records to the right people
  • Auditable compliance records meeting MoD and government estate requirements

Questions & Answers

Legionella monitoring software, answered

What does Legionella monitoring software do?
The software is the cloud platform that receives readings from the sensors and makes them useful. It checks each reading against the thresholds you set, plots trendlines, raises alerts when a limit is breached or a flush is missed, routes those alerts to the right people, and stores a tamper-evident, exportable record. It is the layer that turns continuous data into management decisions and audit evidence.
Can we set our own thresholds and rules?
Yes. You set control limits per asset, so a cold water tank, a calorifier return, and a sentinel outlet each alarm against the temperatures appropriate to them. You also configure who is notified, on which channel, and how alerts escalate if unanswered. Your duty holder defines the targets in line with HSE guidance, and the software alerts against exactly those values.
How are alerts delivered and escalated?
Alerts go out by SMS, email, and in-app notification in real time when a reading breaches a threshold or a flush is missed. The software supports role-based routing, so the right person for a given site or asset is notified, and escalation rules pass the alert onward if the first responder does not act within the expected window, closing the gap where a single missed alert becomes an unmanaged risk.
Does the software integrate with our other systems?
Yes. The platform is open and interoperable. It exposes a REST API for integration with BMS, CAFM, SCADA, and AIMS, and on site the devices speak RS485/Modbus. This means temperature data and alerts can flow into the systems your estates and engineering teams already use, rather than living in an isolated tool that adds another login to the day.
Can we manage many sites in the software?
Yes. The dashboard is role-based and scales from a single building to a national portfolio, with every asset feeding one view. A central user can see estate-wide status while local teams see and act on their own sites. This lets you compare buildings, prioritise attention, and route alerts locally without losing the overall picture across the portfolio.
What records does the software keep?
It holds every reading and alert in tamper-evident logs with secure timestamps, exportable on demand for a given asset or period. This supports the recordkeeping element of your regime under ACoP L8 and HSG274 Part 2, giving a complete and defensible history rather than sparse manual entries. Responsibility for the written scheme of control remains with your duty holder.
