Legionella Monitoring in East Anglia

East Anglia water risk,
recorded continuously.
However far the site sits.

Across Norwich, Ipswich, Cambridge, and Peterborough, and the rural estates between them, AQUAIOT fits wireless temperature sensors at tanks, calorifiers, loops, and sentinel taps, checking readings against HSE L8 and HSG274 Part 2 continuously.

Man-in-a-van visits leave gapsInspection sheets capture one moment. Between rounds, temperatures drift unseen, and your compliance record has no answer for it.
Legionella thrives between 20C and 45CRisk conditions develop and resolve between visits. Manual schedules cannot catch what happens overnight.
Audit prep should not take daysWhen 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 gapOne undocumented flushing event is a defensible record waiting to fail under legal scrutiny.
The AQUAIOT Solution

Rural distance,
closed by telemetry,
not mileage.

East Anglian estates are defined by spread, council buildings across two large rural counties, food and agricultural processing sites, coastal towns, and research campuses around Cambridge and Norwich. AQUAIOT brings each of those buildings into one continuous L8 record, whether it sits in a city or at the end of a fenland lane.

Continuous temperature profiling at tanks, calorifiers, loops, and sentinel outlets across Norwich, Ipswich, Cambridge, and Peterborough sites.
Threshold alerts against HSE L8 guidance, SMS, email, and app notification when a reading drifts into a risk zone or a flush is missed.
Cellular and LoRaWAN telemetry with encrypted payloads, bringing rural and coastal sites onto one dashboard with audit trails and API integration.

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
Open, interoperable systems. No lock-in. Engineered for operational environments.

Questions & Answers

Legionella monitoring across East Anglia, answered

Do you cover the whole of East Anglia?
Yes. AQUAIOT engineers survey, install, and commission across Norwich, Ipswich, Cambridge, and Peterborough, and throughout rural Norfolk, Suffolk, and Cambridgeshire, as part of UK-wide coverage. Once commissioned, the monitoring is fully remote, so a fenland site reports as continuously as a city-centre building and distance stops shaping the regime.
Can you monitor rural sites with poor mobile signal?
Yes. Sensors report over cellular or LoRaWAN telemetry with encrypted payloads, and where mobile coverage is weak a LoRaWAN gateway carries the readings instead. That suits East Anglia’s flat, dispersed geography, where estates routinely include buildings that sit a long way from the nearest town, mast, or estates office.
Can you monitor food processing and agricultural sites?
Yes. Food and agricultural processing is a major part of the East Anglian economy, and those sites run welfare and process pipework across large footprints. Non-contact retrofit sensors monitor tanks, loops, and sentinel outlets continuously, installation needs no production shutdown, and hygiene-sensitive areas are not disturbed by the work.
Can you cover a council estate dispersed across a rural county?
Yes. Council and public portfolios in Norfolk and Suffolk spread libraries, depots, offices, and community buildings across two large rural counties, which makes manual rounds a scheduling exercise. Fixed sensors bring every building into one dashboard with automatic alerts, so remote sites get the same scrutiny as the town hall.
Can sensors be fitted without shutting down our water system?
Yes. The sensors retrofit into live buildings with no pipe cutting and no shutdown, so occupied offices, wards, housing, and processing sites keep running through installation. Engineers fix them at tanks, calorifiers, loops, and sentinel outlets in a normal working visit, and readings start flowing at the point of commissioning.
Does it integrate with our existing BMS or CAFM system?
Yes. AQUAIOT connects to BMS, CAFM, AIMS, and SCADA platforms over RS485/Modbus or REST API, so East Anglian estates teams keep one source of truth without lock-in. Temperature records and alert histories export cleanly for audits, and role-based dashboards cover the teams working outside those systems day to day.
