Legionella Monitoring in Preston

Preston water risk,
tracked without a round.
Day and night.

Across Preston’s Lancashire NHS sites, the university, and council estates, AQUAIOT fits wireless temperature sensors at tanks, calorifiers, loops, and sentinel taps, checking thresholds against HSE L8 and HSG274 Part 2 continuously.

The AQUAIOT Solution

Continuous L8 visibility
for Preston’s
health and civic estate.

Preston’s Lancashire NHS sites, university, and councils manage water risk across large, busy estates. AQUAIOT keeps each one’s L8 record current in real time, so compliance no longer depends on how many rounds a team can complete.

Real-time temperature profiling at tanks, loops, and sentinel outlets across Preston healthcare, campus, and council sites.
Threshold alerts against HSE L8 guidance, immediate SMS, email, and app notification when a reading enters a risk zone or a flush is missed.
Tamper-evident, exportable audit trails, with API, BMS, and CAFM integration for instant compliance evidence.

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

Legionella monitoring in Preston, answered

Do you cover Preston and the surrounding area?
Yes. AQUAIOT engineers survey, install, and commission across Preston and Lancashire, as part of UK-wide coverage. We work across NHS, education, and council sites in the city and surrounding region.
Which Preston sectors do you typically work with?
Preston combines Lancashire NHS sites, the university, and councils. Each carries an L8 duty of care, and continuous monitoring suits both clinical estates with dense pipework and multi-building civic and campus sites.
Can you monitor an NHS site with complex pipework?
Yes. Clinical estates run extensive hot and cold systems with many outlets that are slow to cover on a manual round. Sensors at thermostatic mixing valves, loops, and sentinel outlets monitor them continuously, with one dashboard for the estates team.
Can sensors be fitted without shutting down our water system?
Yes. Our sensors retrofit into live Preston buildings with no pipe cutting and no shutdown, so operational wards, campus buildings, and council offices keep running during installation.
How does this support HSE ACoP L8 compliance?
AQUAIOT records temperatures continuously and alerts when readings move outside guidance, strengthening your written scheme of control with a tamper-evident record. The duty holder remains responsible for the overall control scheme.
Does it integrate with our existing BMS or CAFM system?
Yes. AQUAIOT connects to SCADA, AIMS, CAFM, and BMS platforms over RS485/Modbus or REST API, so Preston estates teams keep one source of truth without lock-in.
