Legionella control
across the
defence estate.

Continuous wireless temperature monitoring across barracks, accommodation blocks, and training estates, with encrypted telemetry and role-based access, checked automatically against HSE L8 and MoD JSP guidance.

Records and telemetry must meet security expectationsOn a secure estate, monitoring data has to be transmitted securely and visible only to the right people, not exposed across open systems.
The AQUAIOT Solution

Continuous cover,
encrypted telemetry,
controlled access.

AQUAIOT fits wireless temperature sensors across accommodation, welfare, and training estate water systems, with encrypted telemetry and role-based access, so your L8 record stays current across the whole estate.

Real-time temperature profiling across calorifiers, loops, sentinel outlets, and accommodation blocks, continuous rather than periodic.
Encrypted telemetry over cellular and LoRaWAN, with secure payload transmission and over-the-air configuration across dispersed and remote sites.
Tamper-evident audit trails with role-based access, and CAFM, BMS, and REST API integration so the right records reach the right people.

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 defence estate

Barracks & Accommodation

Cover blocks through every occupancy cycle.

Barrack and accommodation blocks swing between full and empty as units deploy, driving stagnation risk across outlets. Continuous monitoring tracks that risk without depending on a manual schedule.

  • Continuous monitoring across variable-occupancy accommodation
  • Automatic alerts when vacated blocks develop risk conditions
  • Encrypted telemetry over cellular and LoRaWAN
  • Audit-ready records for MoD and HSE scrutiny
Training Estates

Visibility across dispersed, remote sites.

Training estates spread water assets across large and often remote areas where manual rounds are impractical. Remote sensor coverage gives a live view of every site without the travel.

  • Remote temperature monitoring across dispersed sites
  • Cellular and LoRaWAN telemetry for remote locations
  • Single dashboard view across the whole estate
  • Threshold alerts routed to a central team automatically
MoD Facilities

Defensible records across complex infrastructure.

MoD facilities carry the same L8 duty as any estate, often across ageing and hard-to-reach pipework. Automated monitoring closes the documentation gaps that manual rounds leave behind.

  • Dense coverage across complex and ageing pipework
  • Retrofit-friendly sensors fitted in live environments with no shutdown
  • Tamper-evident timestamped logs for defensible evidence
  • Integration with existing BMS and CAFM infrastructure
Secure Sites

Secure by design, compliant by default.

Secure sites need monitoring that respects access and data-handling expectations. AQUAIOT transmits over encrypted telemetry and shows the right records to the right people through role-based access.

  • Encrypted payload transmission over cellular and LoRaWAN
  • Role-based dashboard access, controlled visibility of records
  • Tamper-evident immutable logs with timestamps and user actions
  • On-demand compliance reports for audits and inspections
Open, interoperable systems. No lock-in. Engineered for operational environments.

Questions & Answers

Legionella monitoring for defence estates, answered

Why do defence estates need automated Legionella monitoring?
Defence estates combine accommodation that empties and refills with deployment cycles, large and dispersed training estates, and ageing pipework that is hard to reach, all of which leave gaps in manual monitoring. Continuous sensor-based monitoring keeps every site visible and logged around the clock and tracks stagnation risk in vacated accommodation automatically.
Is the telemetry secure?
Yes. AQUAIOT transmits temperature data over cellular and LoRaWAN with encrypted payloads, supports over-the-air configuration, and holds records in tamper-evident logs. Role-based dashboard access controls who can see which records, so the right data reaches the right people.
Does it support HSE L8 and MoD JSP water safety guidance?
AQUAIOT supports your duty holder responsibilities under the HSE Approved Code of Practice L8 and MoD JSP water safety guidance by recording temperatures continuously and alerting when readings drift outside guidance. It strengthens the written scheme of control with a complete, tamper-evident record. Responsibility for the overall control scheme remains with your duty holder.
Can dispersed and remote sites be monitored centrally?
Yes. Sensors report over cellular and LoRaWAN, so dispersed accommodation and remote training estates can be monitored from a single dashboard, with threshold alerts routed to a central team automatically and no need for travel between sites.
Can sensors be fitted on ageing accommodation pipework?
Yes. Sensors are retrofit-friendly and fitted in live environments with no pipe cutting and no shutdown required. Our engineers handle the site survey, installation, and commissioning, including across older and complex pipework.
How quickly can compliance evidence be produced?
Every reading and alert is held in tamper-evident logs and is exportable on demand. Producing temperature evidence for an MoD or HSE inspection takes minutes rather than days of compiling paper logbooks.
