Inefficiencies hide in plain sight

When inefficiencies go unseen, entire communities feel the impact — from higher costs to interrupted service.

Manual checks slow response times

Wasted clean water from leaks, overflows, or undetected faults

Faults often go unnoticed until too late

Replacements cost millions

Smart heat monitoring. Zero disruption

Seamless integration. Real-time data. Lasting performance.

 Waltero’s W-Sensors retrofit directly onto existing systems in less than a minute — no shutting down power, no retraining needed. Our sensors provide scheduled consumption readings, connect via networks like LoRa, NB-IoT, LTE-M, and feed data into Mimir, our AI dashboard. Forecasting, demand planning, and efficiency become simple, continuous, and actionable.

Go From What Happened?to We Saw It Coming

With Waltero, you’ll know about faults and failures before they disrupt your business – and before they cost you millions.
