Water Hygiene Monitoring

Temperature.
Flushing. Records.
One regime, one view.

Water hygiene is more than one reading. It is temperatures held, outlets flushed, and records kept, all part of the water safety plan. AQUAIOT brings the whole regime into one dashboard, so the plan is evidenced end to end.

The AQUAIOT Solution

The whole regime.
Not just
the temperatures.

Water hygiene covers the full control regime behind safe water: temperatures, flushing, and the records that prove them. AQUAIOT monitors the lot continuously and gathers it into one view, so the water safety plan is backed by live evidence.

Temperatures held and proven, continuous profiling at tanks, calorifiers, loops, TMVs, and sentinel outlets against the thresholds your plan sets.
Flushing tracked, not assumed, missed flushes flagged and completed ones evidenced, so the routine control of little-used outlets is proven.
One record for the plan, every reading, alert, and flush in one tamper-evident, exportable log that maps to your water safety plan.

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

Water hygiene monitoring, answered

What is water hygiene monitoring?
Water hygiene monitoring is the continuous oversight of the controls that keep a water system safe: temperatures at tanks, calorifiers, loops, and outlets, the flushing of little-used points, and the records that evidence them. Rather than confirming each control on separate periodic rounds, AQUAIOT watches them continuously and gathers the whole regime into one dashboard that maps to your water safety plan.
How is it broader than temperature monitoring?
Temperature monitoring is one part of water hygiene. The wider regime also covers flushing of infrequently used outlets, management of dead legs, and the recordkeeping that proves the plan is followed. AQUAIOT captures temperatures continuously, flags missed flushes, evidences completed ones, and holds it in a single tamper-evident record, so the full hygiene regime is monitored rather than just the temperatures.
What is a water safety plan?
A water safety plan is the documented approach a duty holder takes to manage the risks in a water system, setting out the assets, controls, responsibilities, and monitoring involved. It follows the principles of ACoP L8 and HSG274, with healthcare estates using HTM 04-01. AQUAIOT provides the continuous monitoring and records that evidence the control measures the plan describes, supporting the duty holder who owns it.
Does one dashboard really cover the whole regime?
Yes. Temperatures, threshold breaches, missed flushes, and completed flushes all feed the same role-based dashboard, with trendlines and exportable records. This means the elements of the hygiene regime that traditionally live in separate logbooks and rounds are visible in one place, so the person governing water safety sees the whole plan rather than piecing it together from scattered records.
How does it support our compliance regime?
By evidencing the control measures behind your water safety plan continuously. Temperature control, flushing, and recordkeeping are all captured in one tamper-evident, exportable record that supports your duties under ACoP L8 and HSG274 Part 2, with HTM 04-01 for healthcare. Responsibility for the plan and the regime remains with your duty holder and competent people; AQUAIOT makes the monitoring and evidence robust.
Can water hygiene monitoring be retrofitted?
Yes. AQUAIOT sensors are designed for retrofit in live environments with no pipe cutting or shutdown, and our engineers handle the survey, installation, and commissioning. An existing water system can be instrumented across its tanks, calorifiers, loops, and outlets without interrupting supply, then report continuously to one dashboard covering the whole hygiene regime from the moment it goes live.
