From the pumping station to the chlorination plant, Eziwan covers the entire water cycle in your communities.
Connect your existing instruments without replacing them. Eziwan supports the water industry's native protocols.
Operators of wastewater treatment systems are subject to strict regulatory requirements for self-monitoring. Eziwan is designed to meet these requirements out of the box.
Requires continuous monitoring of discharge parameters for wastewater treatment plants and collection systems. Eziwan automatically archives time-stamped measurements and generates the required annual reports.
All monitoring data (flow rates, analyses, alarms) are retained for at least 5 years in our data centers located in France, with guaranteed access for the relevant authorities.
Export data in a format compatible with SANDRE (National Service for Water Data and Repositories) for transmission to SATESE and government agencies.
Each alarm (overflow, threshold exceeded, communication failure) is time-stamped to the second, acknowledged, and archived. This serves as legal evidence for litigation and prefectural formal notices.
Automatic generation of the annual operating report (RPQS) with performance indicators, network performance, and a summary of alarms. Export to PDF or send digitally.
The Eziwan platform is hosted exclusively in French data centers. GDPR-compliant, no data transfers outside the EU, ISO 27001 certified. Ideal for government procurement.
Les SATESE (Technical Assistance Services for Wastewater Treatment Plant Operators) can access the data directly through a dedicated portal. The export format SANDRE (National Water Data and Reference Systems Administration) is responsible for data transfers to the Water Agencies and the DREAL.
The utility operated 47 pumping and lift stations spread across 12 municipalities in the Oise department. Monitoring relied on SOFREL S4W GPRS modems installed between 2009 and 2012. Since the phased shutdown of Orange’s 2G network in 2024, 31 stations have stopped transmitting any alarms, leaving maintenance crews completely unaware of incidents.
Replacement of the 47 SOFREL S4W modems with Eziwan LTE gateways in 4 weeks. Retained the existing RS-485 cabling. Migrated the 210 Modbus registers (levels, pump statuses, hour meters, overflow alarms) to the cloud platform. Trained the 6 operations technicians in half a day.
"The migration went smoothly for our teams. In less than a week, all our stations were sending their alarms over 4G. The improvement in responsiveness was immediate—before, we would only discover outages during our weekly rounds."
— Operations Manager, Oise Valley Water Authority
