Legionella Monitoring in the North East

North East water safety,
watched day and night.
Tyne, Wear, and Tees.

Across Newcastle, Sunderland, Durham, and Gateshead, AQUAIOT fits wireless temperature sensors at tanks, calorifiers, loops, and sentinel taps, checking every reading against HSE L8 and HSG274 Part 2 through the night, the weekend, and the holiday shutdown.

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.

The AQUAIOT Solution

Alerts that reach
the right person,
whatever the hour.

Water systems in the North East do not build risk on a schedule. A calorifier drifts on a Friday night, a housing block loses its flushing routine over a bank holiday. AQUAIOT watches continuously and routes alerts by role, with escalation if the first person cannot respond.

Continuous temperature profiling at tanks, calorifiers, loops, and sentinel outlets across Newcastle, Sunderland, Durham, and Gateshead sites.
Role-based alert routing with escalation, SMS, email, and app notifications that follow the on-call rota rather than the office day.
Tamper-evident, exportable audit trails, with API, BMS, and CAFM integration so evidence is ready on demand.

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 in the North East, answered

Do you cover the whole of the North East?
Yes. AQUAIOT engineers survey, install, and commission across Newcastle, Sunderland, Durham, and Gateshead, and throughout Northumberland and Teesside, as part of UK-wide coverage. Once sensors are commissioned the monitoring is fully remote, so every site reports continuously and visits happen when the work needs hands on pipework, not to collect numbers.
Who receives alerts outside office hours?
Whoever you decide should. Alerts route by role over SMS, email, and app notification, with escalation rules if the first contact does not respond. A calorifier drifting at two in the morning reaches the on-call engineer immediately, and the estates lead sees the full event trail, including response times, the next day.
Which North East sectors do you typically work with?
The North East combines NHS estates, universities, large social housing portfolios, industrial sites, and coastal towns whose buildings see seasonal swings in use. Each carries an L8 duty of care, and continuous monitoring suits the region’s mix of dense urban stock and sites spread along the coast and across the counties.
Can you monitor social housing across multiple sites?
Yes. Across communal blocks and individual dwellings, manual L8 rounds leave gaps, especially in void properties where nobody runs the taps. Fixed sensors give one dashboard across the whole portfolio and raise automatic alerts when a low-use or vacant property starts developing risk conditions, so teams act before risk becomes an incident.
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 homes, wards, and offices across the North East keep running through installation. Engineers fix them at tanks, calorifiers, loops, and sentinel outlets in a normal working visit, and readings start flowing immediately after 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 North East estates teams keep one source of truth without lock-in. Alert histories and temperature records export cleanly, which matters when out-of-hours events need reviewing with contractors or auditors afterwards.
