Cell outlets are hard to reach for manual roundsAccess to occupied cells is controlled and time-consuming, so manual temperature checks across hundreds of in-cell outlets are slow and easy to miss.
Intermittent use creates stagnation riskCells empty and refill, wings open and close, and outlets sit unused for stretches, leaving stagnation conditions that periodic rounds rarely catch in time.
A vulnerable population raises the duty of careA closed, dependent population means the consequences of a Legionella incident are severe, and the L8 duty of care is held to a high standard.
Equipment must survive a secure environmentMonitoring hardware in a custodial setting has to be tamper-resistant and discreet, not exposed kit that becomes a liability.
The AQUAIOT Solution

Continuous cover
where access is hard
and stakes are high.

AQUAIOT fits tamper-resistant wireless temperature sensors across cells, wings, and welfare outlets, monitoring and alerting around the clock so your L8 record stays current without repeated controlled access.

Real-time temperature profiling across in-cell outlets, wing risers, calorifiers, loops, and sentinel taps, continuous rather than periodic.
Threshold alerts against HSE L8 guidance, immediate SMS, email, and app notification when readings drift into the risk band or a flush is missed.
Tamper-evident, exportable audit trails, with encrypted telemetry and CAFM, BMS, and REST API integration for instant compliance evidence.

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 secure estate

Prisons

Cover every outlet, even hard-to-reach cells.

Prisons combine hundreds of intermittently-used in-cell outlets with controlled access that makes manual rounds slow. Continuous monitoring keeps every outlet visible without repeated entry to occupied areas.

  • Continuous temperature profiling across cells, wings, and welfare
  • Tamper-resistant sensors suited to the custodial environment
  • Automatic alerts when intermittently-used outlets drift into risk
  • Audit-ready records for HMPPS and HSE scrutiny
Secure Hospitals

Clinical water safety in a secure setting.

Secure hospitals carry both clinical water safety expectations and the access constraints of a controlled environment. Automated monitoring meets the higher standard while removing the manual burden on staff.

  • Dense outlet coverage across wards and patient areas
  • Real-time monitoring at thermostatic mixing valves and outlets
  • Tamper-evident timestamped logs for defensible records
  • Integration with existing BMS and CAFM infrastructure
Detention Facilities

Reliable cover for transient populations.

Detention and immigration removal facilities see frequently changing occupancy, which drives stagnation risk across outlets as areas empty and refill. Continuous monitoring tracks that risk without depending on manual schedules.

  • Continuous monitoring across variable-occupancy areas
  • Automatic alerts when vacant areas develop risk conditions
  • Tamper-resistant sensors and encrypted telemetry
  • On-demand compliance reports for audits and inspections
Estates Teams

Run L8 across the estate from one dashboard.

Estates teams managing secure sites own the L8 duty across complex, aging pipework and controlled-access areas. AQUAIOT gives them a single live view and a complete record behind it.

  • Single dashboard view across all monitored outlets and assets
  • Role-based access, the right records to the right people
  • Retrofit-friendly sensors fitted in live environments with no shutdown
  • Reduced reliance on manual rounds and controlled-access visits
Open, interoperable systems. No lock-in. Engineered for operational environments.

Questions & Answers

Legionella monitoring for prisons, answered

Why do prisons need automated Legionella monitoring?
Prisons combine hundreds of intermittently-used in-cell outlets, controlled access that slows manual rounds, and a vulnerable, dependent population, all of which raise the L8 duty of care. Continuous sensor-based monitoring keeps hard-to-reach outlets visible and logged around the clock without repeated controlled access.
Is the monitoring hardware tamper-resistant?
Yes. AQUAIOT sensors are suited to the custodial environment with tamper-resistant fitting, and all temperature data is held in tamper-evident logs with secure timestamps. Telemetry is transmitted with encrypted payloads.
How are hard-to-access cell outlets covered?
Wireless sensors are fitted at in-cell outlets, wing risers, calorifiers, loops, and sentinel taps. Once installed, they profile temperatures continuously and report remotely, removing the need for repeated controlled access to record readings.
Does it support HSE L8 and HMPPS requirements?
AQUAIOT supports your duty holder responsibilities under the HSE Approved Code of Practice L8 across the secure estate 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 sensors be fitted without disrupting the regime?
Yes. Sensors are retrofit-friendly and fitted in live environments with no pipe cutting and no shutdown required. Our engineers plan the site survey, installation, and commissioning around the operational regime and access procedures.
How quickly can audit evidence be produced?
Every reading and alert is held in tamper-evident logs and is exportable on demand. Producing temperature evidence for an HMPPS or HSE inspection takes minutes rather than days of compiling paper logbooks.
