University Legionella Monitoring in Leeds

Leeds campuses fill and empty
with every term.
The monitoring never does.

A Leeds university estate cycles hard, packed teaching weeks, quiet reading weeks, dead vacations, and halls that thin out every weekend. AQUAIOT fits wireless temperature sensors at tanks, calorifiers, loops, TMVs, and sentinel outlets, checking readings against HSE ACOP L8 and HSG274 Part 2 through every swing in occupancy.

The AQUAIOT Solution

Water safety that holds
through reading weeks,
vacations, and clearing.

Occupancy in Leeds student buildings never sits still. Halls around Hyde Park and Headingley empty at weekends, teaching blocks go quiet for weeks at a time, and usage shifts with every timetable change. AQUAIOT monitors continuously, so control does not depend on predicting who is in which building.

Real-time temperature profiling at tanks, calorifiers, loops, TMVs, and sentinel outlets across Leeds campus and hall buildings, whatever the term calendar says.
Threshold alerts against HSE L8 guidance, SMS, email, and app notification when low occupancy lets an outlet drift into a risk zone or a flush is missed.
Tamper-evident, exportable audit trails, with API, BMS, and CAFM integration, one live record through every occupancy cycle.

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

University Legionella monitoring in Leeds, answered

Do you cover university campuses across Leeds?
Yes. AQUAIOT engineers survey, install, and commission across Leeds and West Yorkshire, as part of UK-wide coverage. We cover city-centre teaching precincts, halls of residence in the student neighbourhoods, sports grounds, and research buildings, and a single deployment can take in every site the estate runs.
How does monitoring cope with constantly changing occupancy?
By not depending on occupancy at all. Fixed sensors read tanks, calorifiers, loops, TMVs, and sentinel outlets on a continuous schedule whether a building is full, half-term quiet, or completely empty. Stagnation shows up as temperature drift and missed flushes the moment it starts, rather than at the next manual round after the students have already returned.
What about reading weeks and short vacations?
Short quiet spells are long enough for outlets to drift, which is why they catch estates teams out. A reading week leaves en-suite blocks and teaching-floor outlets unused for days at a stretch. AQUAIOT flags exactly which outlets went quiet and whether flushing happened, so a short vacation never turns into an unrecorded gap in the scheme.
Can you cover halls in Hyde Park and Headingley as well as campus?
Yes. Sensors in outlying halls report over cellular or LoRaWAN telemetry into the same dashboard as the main precinct, so dispersed residences and central teaching buildings sit in one record. Alerts route to the right hall or campus team, and the estates centre keeps a single view across the whole portfolio.
How does this support our written scheme of control?
It gives the scheme continuous, timestamped evidence instead of monthly snapshots. Readings are checked against HSG274 Part 2 guidance, alerts and responses are logged, and the whole record is tamper-evident and exportable for auditors or the water safety group. The university remains the duty holder, with responsibility for the overall scheme staying in house.
Can sensors be fitted without disturbing students in residence?
Yes. The sensors retrofit onto live systems with no pipe cutting and no shutdown, so halls keep hot water and heating throughout installation. Our engineers schedule survey and commissioning work around teaching hours and hall routines, and most rooms are covered from communal risers and sentinel points rather than by entering every bedroom.
