Reactive to preventive: how SE3 brings IT/OT monitoring to wastewater treatment plants with PRTG 

Challenge: Fragmented OT data across independent plant systems; no unified IT/OT visibility for operators

The problem

SE3 is a Mexican MSP specializing in industrial automation and digitization for the water and energy sectors. Its client JAPAY is the public authority responsible for potable water and sanitation across the city of Mérida and surrounding municipalities.

JAPAY operates 36 wastewater treatment plants and 16 pumping stations. Each plant runs its own independent technology platform, with different brands and systems creating fragmented data. Plant managers had to navigate multiple interfaces just to understand the current state of operations, making early detection of problems nearly impossible.

The wastewater environment is harsh on equipment. Without unified visibility, maintenance was reactive and unplanned visits by electricians were frequent and expensive.

What changed with PRTG

SE3 integrated PRTG with INSYS routers deployed at each plant. The routers translate industrial protocols into MQTT and transmit data via mobile network to a cloud broker, where PRTG then collects and displays everything in one place.

From a single dashboard, operators can now monitor engine speeds, valve status, water levels in tanks, pump activity, UPS systems, energy consumption, and surveillance cameras across all locations. OT and IT components appear together with no separate tools or interfaces.

Plant managers access live measurement values and alerts from any browser or mobile device. Critical thresholds trigger notifications before issues escalate.

SE3 also delivered this at significantly lower cost than expanding an existing SCADA system, without compatibility issues across the different brands already deployed in JAPAY's plants.

When we integrate PRTG from Paessler, we provide a solution that allows the visualization of all industrial and communication components in a single system.
