Legionella Monitoring for Local Authorities

Legionella control
across the
council portfolio.

Diverse portfolios are hard to monitor consistentlyCivic centres, leisure centres, libraries, and depots all carry different water systems, and manual rounds rarely apply the same standard everywhere.
Stretched teams cannot cover every siteCouncil estates teams manage many buildings with limited resource, so periodic manual checks leave gaps across the portfolio.
Public buildings carry public-facing riskLeisure showers, public washrooms, and community facilities serve large numbers of people, raising the stakes of any Legionella incident.
Records sit in silos across departmentsWhen an inspection or FOI request lands, pulling temperature evidence from scattered logbooks across departments is slow and incomplete.
The AQUAIOT Solution

One standard
across every
building you own.

AQUAIOT fits wireless temperature sensors across your property portfolio, monitoring and recording around the clock so every council building meets the same L8 standard from one dashboard.

Real-time temperature profiling across calorifiers, loops, sentinel outlets, and public-facing facilities, continuous rather than periodic.
Threshold alerts against HSE L8 guidance, immediate SMS, email, and app notification when readings drift into the risk band or a flush is missed.
Tamper-evident, exportable audit trails, with CAFM, BMS, and REST API integration for instant evidence across the whole portfolio.

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 council water risk

Corporate Property

One view across the whole estate.

Corporate property teams hold the L8 duty across a diverse and dispersed council estate. Continuous monitoring gives a single live view and the same standard at every building, regardless of department.

  • Continuous monitoring across all council buildings, single dashboard
  • Automatic alerts when any site develops risk conditions
  • Audit-ready records for HSE, insurer, and FOI purposes
  • CAFM and property management system integration
Public Buildings

Protect the public who use your buildings.

Civic centres, libraries, and community buildings serve the public daily and carry public-facing water risk. Automated monitoring keeps that risk visible across high-footfall facilities.

  • Continuous temperature profiling across public-facing outlets
  • Automatic alerts when low-use outlets drift into risk
  • Tamper-evident timestamped logs for defensible records
  • Integration with existing BMS and CAFM infrastructure
Leisure & Community

Higher-risk water systems, watched continuously.

Leisure centres and community facilities run showers, pools-adjacent plant, and high-use welfare systems that sit firmly in the Legionella risk picture. Continuous monitoring keeps eyes on them around the clock.

  • Dense coverage across showers and high-use welfare outlets
  • Real-time monitoring at calorifiers, loops, and sentinel outlets
  • Threshold alerts routed to the right responder automatically
  • On-demand compliance reports for facility managers
Compliance Teams

Defensible evidence, ready on demand.

Council compliance teams answer to auditors, insurers, and public scrutiny across the whole estate. AQUAIOT gives them one complete, exportable record behind every monitored building.

  • Single dashboard view across all monitored buildings
  • Role-based access, the right records to the right teams
  • Exportable evidence for audits, insurers, and FOI requests
  • Reduced reliance on siloed manual logbooks
Open, interoperable systems. No lock-in. Engineered for operational environments.

Questions & Answers

Legionella monitoring for local authorities, answered

Why do local authorities need automated Legionella monitoring?
Councils hold the L8 duty of care across diverse property portfolios, from civic centres and libraries to leisure facilities and depots, with stretched estates teams that cannot reach every site on schedule. Continuous sensor-based monitoring applies the same standard to every building and keeps each one visible and logged around the clock from a single dashboard.
Can a whole property portfolio be managed in one place?
Yes. Every monitored building reports to a single dashboard with role-based access, so corporate property sees the whole estate while individual facility managers see their own sites, and threshold alerts route to the right responder automatically.
Does it support HSE L8 compliance across council buildings?
AQUAIOT supports your duty holder responsibilities under the HSE Approved Code of Practice L8 across the portfolio by recording temperatures continuously and alerting when readings drift outside guidance. It strengthens the written scheme of control with a complete, tamper-evident record. Responsibility for the overall control scheme remains with your duty holder.
How does it help with public-facing facilities like leisure centres?
Leisure centres and community buildings run high-use showers and welfare systems that sit firmly in the Legionella risk picture. Dense sensor coverage profiles temperatures continuously at those outlets and alerts immediately when readings drift into the risk band.
Can sensors be fitted across older council buildings without disruption?
Yes. Sensors are retrofit-friendly and fitted in live environments with no pipe cutting and no shutdown required. Our engineers handle the site survey, installation, and commissioning across the varied buildings in your portfolio.
How quickly can evidence be produced for an audit or FOI request?
Every reading and alert is held in tamper-evident logs and is exportable on demand. Producing temperature evidence for an HSE inspection, an insurer, or an FOI request takes minutes rather than days of compiling logbooks across departments.
