Automated Legionella Monitoring
Know your
water risk.
Automatically.
Wireless temperature sensors at tanks, calorifiers, loops, and sentinel taps — checking thresholds against L8, HSG274 Part 2, and HTM 04-01, automatically, around the clock.

Man-in-a-van visits leave gaps
Inspection sheets capture one moment. Between rounds, temperatures drift unseen — and your compliance record has no answer for it.
Legionella thrives between 20°C–45°C
Risk conditions develop and resolve between visits. Manual schedules can't catch what happens overnight.
Audit prep shouldn't take days
When an inspector asks for records, paper logbooks take days to compile. A digital audit trail is instant.
Every missed flush is a duty-of-care gap
One undocumented flushing event is a defensible record waiting to fail under legal scrutiny.
The AQUAIOT Solution
Continuous visibility.

Continuous visibility.
Automatic records.
Defensible compliance.
AQUAIOT replaces time-consuming manual rounds with continuous automated monitoring — so your L8 compliance record is always current, always accurate, and always ready.
Real-time temperature profiling at tanks, loops, and sentinel outlets — continuous, not periodic.
Threshold alerts against HSE L8 guidance — immediate SMS, email, and app notification when temperatures drift into risk zones or a flush is missed.
Tamper-evident, exportable audit trails — API, BMS, and CAFM 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/ACoP guidance. Alerts fired immediately when cold water exceeds 20°C or hot water falls below 50°C 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.
Compliance & Standards
Every temperature round you skip is a gap in your duty-of-care record. AQUAIOT closes that gap automatically — thresholds checked against HSE guidance, every reading logged, every missed flush flagged.

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's 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, no more
- Auditable compliance records meeting MoD and government estate requirements
