University Legionella Monitoring in Bristol

A 2am alert in a Bristol hall
beats a Monday logbook.
Every campus outlet, live.

Bristol university estates spread across a hilly city, from harbourside buildings to Georgian terraces converted into departments, and water risk does not keep office hours. AQUAIOT monitors tanks, calorifiers, loops, TMVs, and sentinel outlets against HSE ACOP L8 and HSG274 Part 2 continuously, with alerts routed to whoever is on call.

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 Bristol engineer,
at any hour.

When a calorifier drops on a Friday night, a Bristol estates team should not find out from Monday’s round. AQUAIOT checks every reading the moment it is taken and routes alerts by role, with escalation if nobody acknowledges, so out-of-hours risk gets an out-of-hours response across the whole campus.

Real-time temperature profiling at tanks, calorifiers, loops, TMVs, and sentinel outlets across Bristol campus buildings, day, night, and vacation.
Threshold alerts against HSE L8 guidance, SMS, email, and app notification with role-based routing and escalation rules, so an unacknowledged alert climbs until someone acts.
Tamper-evident, exportable audit trails, with API, BMS, and CAFM integration, every alert and response on the record.

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

University Legionella monitoring in Bristol, answered

Do you cover university sites across Bristol?
Yes. AQUAIOT engineers survey, install, and commission across Bristol and the South West, as part of UK-wide coverage. We work across hillside teaching precincts, harbourside buildings, converted Georgian terraces, halls of residence, and sports grounds, bringing every site into one monitoring deployment however scattered the estate is.
How does out-of-hours alerting actually work?
Every reading is checked against HSE L8 thresholds as it arrives, at any hour. When something drifts, the system sends SMS, email, and app notifications to the people on call for that site, and escalation rules pass the alert up the chain if it goes unacknowledged. Night and weekend events get a response, not a Monday discovery.
Can alerts route differently for halls and teaching buildings?
Yes. Routing is role-based and per site, so a hall warden team, a campus maintenance desk, and an out-of-hours contractor can each receive the alerts relevant to their buildings. The estates centre still sees everything on one dashboard, and every alert and acknowledgement lands in the same auditable record.
Can you monitor converted Georgian buildings?
Yes. Departments housed in terraces bring awkward pipe runs, hidden risers, and outlets spread over many small floors, which makes manual rounds slow and patchy. Wireless retrofit sensors fit with no pipe cutting and no shutdown, turning the hardest buildings to walk into the easiest ones to evidence.
What happens over the summer vacation?
Monitoring simply continues. Vacated halls and quiet teaching floors are watched for temperature drift and missed flushes through the whole vacation, with alerts still routing to the summer on-call rota. The estates team returns in September with a continuous, exportable record instead of a three-month gap.
Who remains the duty holder under HSE ACOP L8?
The university does. ACOP L8 keeps responsibility for the risk assessment and the written scheme of control with the duty holder and responsible persons. AQUAIOT strengthens that scheme with continuous readings, out-of-hours alerting, and tamper-evident records, but accountability for the overall regime stays with the institution.
