Legionella Monitoring for Student Accommodation

Safe water for students,
monitored continuously.
Through every summer void.

Wireless temperature sensors at tanks, loops, sentinel taps, and ensuite outlets across halls and PBSA blocks, checking thresholds against HSE L8 automatically, around the clock.

Long summer voids let water stagnateHalls and PBSA blocks empty out for months over the summer, leaving water sitting in thousands of ensuite outlets where temperatures can drift into the growth range unseen.
Ensuite density multiplies the outletsModern student blocks pack dense ensuite bathrooms across many floors, far more outlets than a manual round can profile at the frequency L8 expects.
High turnover leaves rooms idleRooms vacated mid-year, between tenancies, and across the summer sit unused for long stretches, and stagnation builds in the gaps between manual checks.
Audit prep across a block is heavyWhen the HSE or a university partner asks for temperature history across the building, compiling records from scattered logs takes the estates team days.
The AQUAIOT Solution

Continuous visibility.
Void cover.
Defensible records.

AQUAIOT replaces manual rounds with continuous automated monitoring across every block, so your L8 record stays current through term, vacation, and long summer voids, and is always ready for inspection.

Real-time temperature profiling at tanks, loops, sentinel outlets, and ensuite outlets, continuous rather than periodic.
Threshold alerts against HSE L8 guidance, immediate SMS, email, and app notification when a vacated room develops risk or a flush is missed during a void.
Tamper-evident, exportable audit trails, CAFM and property management system integration for instant evidence across every block.

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.

Compliance & Standards

Aligned to the standards your auditors check.

Who It’s For

Built for every kind of student housing provider

PBSA Operators

Dense blocks, complete coverage.

Purpose-built student accommodation packs dense ensuite outlets into large blocks that empty and refill across the year. Manual monitoring cannot keep pace with thousands of rooms and the long voids between intakes.

  • Continuous monitoring across every room and riser from one dashboard
  • Automatic alerts when vacated rooms develop risk conditions
  • Documented evidence that water is safe before students arrive
  • Dense coverage at sentinel outlets and circulating loops
University Halls

One picture across every hall.

University halls combine older and newer building stock under central estates oversight, where summer voids and uneven occupancy create long unmonitored gaps in the L8 record.

  • Continuous monitoring across every hall from a single dashboard
  • Role-based access for estates managers and accommodation teams
  • Continuous cover through term, vacation, and summer voids
  • Audit-ready evidence for university governance and external audit
Private Landlords & HMOs

Compliance without a compliance team.

Private landlords and HMO operators carry the same L8 duty of care over shared student housing, usually without dedicated staff. Automation gives a small operation a reliable monitoring record without adding rounds.

  • Automated monitoring without adding to staff workload
  • Immediate alerts when little-used outlets develop risk conditions
  • Audit-ready records ready for inspection at short notice
  • Cellular and LoRaWAN telemetry for properties with limited infrastructure
Estates Teams

Less time on rounds, more on management.

Accommodation estates teams carry L8 obligations across many blocks while resources stay tight. Automation frees skilled people from clipboard rounds and gives the responsible person a live, defensible picture.

  • Replace labour-intensive manual rounds with automated monitoring
  • Reduce reactive call-outs by detecting drift before it escalates
  • Tamper-evident records for audits, inspections, and insurers
  • Retrofit-friendly install with no shutdown of the water system
Open, interoperable systems. No lock-in. Engineered for operational environments.

Questions & Answers

Legionella monitoring for student accommodation, answered

How does automated monitoring support HSE L8 in student accommodation?
AQUAIOT records temperatures continuously at tanks, loops, sentinel outlets, and ensuite outlets across every block and checks them against HSE L8 guidance. It strengthens the duty holder’s written scheme of control with a complete, tamper-evident record, while responsibility for the overall control scheme remains with the provider.
How does it handle long summer voids?
AQUAIOT keeps profiling temperatures continuously while halls are empty over the summer and sends immediate alerts if readings drift into risk zones or a flush is missed, giving documented evidence that water is safe before students arrive.
Can it cover dense ensuite blocks completely?
Yes. AQUAIOT provides dense coverage at sentinel outlets, ensuite outlets, and circulating loops across many floors, monitoring far more points continuously than a manual round can profile at the frequency L8 expects.
Can sensors be fitted without disrupting students?
Yes. AQUAIOT sensors are designed for retrofit in live environments, with no pipe cutting and no shutdown required. Our engineers handle the site survey, installation, and commissioning, often during a vacation period.
How quickly can we produce records for an inspection or partner audit?
Every reading and alert is held in tamper-evident logs with secure timestamps and is exportable on demand, so producing evidence across term and void periods takes minutes rather than days of compiling scattered logs.
Does it integrate with our CAFM or property management system?
Yes. AQUAIOT is open and interoperable, connecting to CAFM, BMS, and analytics platforms over RS485/Modbus or REST API, with no vendor lock-in.
