THE PROBLEM

GPRS is dead—your stations
are no longer really supervised

The phase-out of the 2G/3G network has disrupted hundreds of remote meter reading and remote monitoring systems in the water sector. Local governments and service providers are now left with isolated stations that lack a reliable alarm notification system.

GPRS 2G/3G Shutdown

Since 2023, carriers have been gradually shutting down their 2G and 3G networks. Thousands of GPRS modems installed at pumping stations are no longer communicating. Alarms are not being received.

Isolated stations in rural areas

Pumping stations, reservoirs, and pumping stations are often located in areas with no service or very limited network coverage. It is impossible to install a fixed ADSL or fiber-optic line.

Regulatory Risks

The Water Framework Directive and prefectural decrees require continuous monitoring of facilities. Failure to comply with these monitoring requirements may result in penalties and a formal notice to the service.

THE EZIWAN SOLUTION

Industrial 4G LTE SCADA
for distributed water systems

The Eziwan gateway is designed for the harsh environments of the water sector: unstable power supply, extreme temperatures, and limited network access. A robust solution for water infrastructure operators.

Native Modbus RTU/TCP

The Eziwan gateway directly reads the data from level sensors, flow meters, pressure sensors, and pump controllers via Modbus RTU over RS-485.

4G LTE dual SIM

Multi-carrier SIM with automatic failover in the event of a network outage. No single point of failure for your critical stations.

Real-time monitoring

A centralized dashboard to view all your stations: levels, flow rates, pump statuses, and real-time energy consumption.

Multi-channel alerts

Configurable thresholds per station: SMS alerts, email, and webhooks to your existing SCADA system. Automatic escalation if no acknowledgment is received within a specified time frame.

Secure VPN

Encrypted OpenVPN tunnel for secure remote access to PLCs. No open ports on the station network.

History & Remote Control

Complete 12-month data history. Remote control of valves and pumps from the control center, with command traceability.

Site Mapping

A map view of all your stations with real-time status. See at a glance which sites are in alarm, which connections are active, and which levels are critical.

SCADA Integration

REST/MQTT API gateway to your existing SCADA software (Wonderware, Ignition, AVEVA, SIMATIC WinCC). Phased migration with no service interruption.

USE CASES

Water sectors monitored using Eziwan

Intermunicipal associations, water utilities, and public service concessionaires

Drinking Water System

Problem

Hundreds of pumping stations, reservoirs, and booster pumps spread across the entire region. The 2G GPRS monitoring system is outdated, and operators receive alarms only after a delay—sometimes after an incident has already caused a disruption in service.

Eziwan Solution

Eziwan replaces GPRS modems with an industrial 4G LTE gateway at each site. Modbus data (levels, pressures, flow rates, equipment statuses) is transmitted in real time. Alerts are sent instantly via text message and email, with mandatory acknowledgment.
