SECURUS/Use Cases/Drinking water hygiene

Temperature monitoring to support drinking water hygiene

Temperatures at storage tanks, circulation loops and pipes help assess drinking water system operation. SECURUS collects readings at suitable points and reports deviations from defined ranges. Temperature monitoring supports drinking water hygiene and records unusual thermal conditions.

How it works

From the reading to the right person.

01

Measure

Sensors record readings or events directly on site.

Circulation return · 51.2 °C
02

Transmit

Via LoRaWAN to a gateway within range, then through its internet connection to the platform.

03

Check

The platform checks every value against your thresholds, rules and time windows.

Below 55 °C
04

Alert

The responsible person receives an SMS or email with location, time and trigger.

The right measuring points

The most meaningful points are the storage tank outlet, the circulation return and critical pipe sections. Clamp-on probes measure at the pipe surface, which may differ from the water temperature, so fixing and insulation matter. We select suitable temperature probes with you.

No substitute for testing

A temperature sensor does not detect legionella or other germs; unremarkable readings are no proof of safe water. Required microbiological testing and operator duties remain in place, and the limits are set by those responsible for the specific system. Other parameters are covered by water quality monitoring.

Use temperature histories for operational checks

When readings look unusual, staff can compare the storage outlet, circulation return and other agreed monitoring points over the same period. This helps narrow down when a change occurred and inform the specialist contractor. In care facilities and residential buildings, use clear equipment names and record the measurement method.

FAQ

Frequently asked questions about drinking water temperature monitoring

Does SECURUS detect legionella?

No. That requires microbiological testing. The temperature data supports the operation of the system.

Can the data be documented?

Yes, as a measurement history and CSV export. Whether that is enough for a particular record depends on the measuring method and requirements.

Can the probes be retrofitted?

Yes. Clamp-on probes are attached to the outside of the pipe without opening it.

Who defines temperature limits?

Those responsible for the system agree limits with qualified specialists. A general sensor value does not replace this planning.
