Legionella Monitoring for Leisure Centres

High-use showers,
monitored continuously.
Through every busy day.

Wireless temperature sensors at tanks, loops, sentinel taps, and shower groups, checking thresholds against HSE L8 and HSG274 automatically, around the clock.

High-use showers demand close attentionBanks of showers used by hundreds of people a day are a focal point for water-safety risk. A periodic manual round cannot watch them continuously.
Spa pools carry heightened riskSpa pools sit alongside L8 duties within their own HSG282 context, where warm, aerosolised water raises risk and demands closer monitoring than a clipboard provides.
High footfall raises the cost of failureThousands of people pass through a busy leisure centre each week. A water-safety incident affects a large public group and the operator’s standing.
Inspections expect a complete recordWhen the HSE or a local authority asks for temperature history, paper logbooks across plant rooms and shower areas take time to compile and often show gaps.
The AQUAIOT Solution

Continuous visibility.
Automatic records.
Public safety assured.

AQUAIOT replaces manual rounds with continuous automated monitoring across showers, loops, and plant, so your L8 record stays current through every busy day and is always ready for inspection.

Real-time temperature profiling at tanks, loops, sentinel outlets, and shower groups, continuous rather than periodic.
Threshold alerts against HSE L8 and HSG274, immediate SMS, email, and app notification when temperatures drift into risk zones or a flush is missed.
Tamper-evident, exportable audit trails, instant evidence for inspectors, local authorities, and insurers.

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 every kind of leisure operator

Local Authority Leisure

Public facilities, public accountability.

Council-run leisure centres serve large public populations and answer to auditors and residents for water safety. Automation gives a stretched team an always-current, defensible monitoring record across busy facilities.

  • Continuous monitoring across showers, pools, and plant from one dashboard
  • Immediate alerts when temperatures drift into risk zones
  • Tamper-evident records for council governance and external audit
  • Role-based access for facility managers and the responsible person
Private Gyms

Member safety without manual rounds.

Private gyms and health clubs run high-use changing and shower facilities under the same L8 duty of care, usually without dedicated water-safety staff. Continuous monitoring covers the risk without adding rounds.

  • Automated monitoring without adding to staff workload
  • Continuous profiling at high-use shower and changing outlets
  • Audit-ready records ready for inspection at short notice
  • Retrofit-friendly install with no shutdown of facilities
Spa & Wellness

Close watch on higher-risk water.

Spa and wellness areas combine warmth and aerosol generation that raise Legionella risk, sitting alongside HSG282 spa pool considerations and demanding closer monitoring than a periodic round provides.

  • Continuous profiling at spa plant and associated outlets
  • Immediate alerts when temperatures drift outside HSE and HSG274 guidance
  • Tamper-evident records for the responsible person and inspectors
  • Cellular and LoRaWAN telemetry across spa plant areas
Swimming Facilities

Showers and changing, fully covered.

Swimming facilities pair pool plant with banks of high-use showers and changing rooms, all carrying water-safety duties. Continuous monitoring tracks temperatures across these busy areas without manual rounds.

  • Dense profiling at shower groups and sentinel outlets
  • Alerts when high-use or seasonal areas develop risk conditions
  • Audit-ready records for facility managers and inspectors
  • BMS and CAFM integration across plant and outlets
Open, interoperable systems. No lock-in. Engineered for operational environments.

Questions & Answers

Legionella monitoring for leisure centres, answered

How does automated monitoring support HSE L8 and HSG274 in leisure centres?
AQUAIOT records temperatures continuously at tanks, loops, sentinel outlets, and shower groups and checks them against HSE L8 and HSG274 Part 2 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 operator.
Can it monitor high-use shower groups continuously?
Yes. AQUAIOT profiles temperatures at shower groups and sentinel outlets continuously and sends immediate alerts when readings drift into risk zones, covering the high-use areas a periodic manual round cannot watch.
How does it relate to spa pools and HSG282?
AQUAIOT provides continuous temperature monitoring at spa plant and associated outlets that supports L8 and HSG274 duties, sitting alongside the wider HSG282 spa pool considerations that the operator manages as part of the overall control scheme.
Can sensors be fitted without closing the facility?
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 around opening hours.
How quickly can we produce records for an inspection?
Every reading and alert is held in tamper-evident logs with secure timestamps and is exportable on demand, so producing evidence for the HSE, a local authority, or an insurer takes minutes rather than days of compiling paper logs.
Does it integrate with our BMS or CAFM system?
Yes. AQUAIOT is open and interoperable, connecting to SCADA, AIMS, CAFM, and BMS platforms over RS485/Modbus or REST API, with no vendor lock-in.
