Eaux de Vienne – Siveer plays a crucial role in managing drinking water at the departmental level, covering all the municipalities of Grand Poitiers, except for the 13 historical communes. Through remote management and a strategic approach to network sectorization, the Syndicate continuously optimizes the distribution and monitoring of water across its territory.
In addition to supplying drinking water, the Syndicate also manages both collective and non-collective sanitation services over a large portion of the department.
Present in 260 municipalities and serving over 300,000 residents, Eaux de Vienne operates an extensive network of 10,000 kilometers, which includes 220 drinking water facilities and 440 sanitation facilities, with 2,500 kilometers of sanitation network. Responsible for water management for its subscribers, Eaux de Vienne-Siveer is committed to maintaining uninterrupted service for all consumers.
Remote management: a key element in network operation, control and monitoring
Today, the Syndicate uses 1,100 remote management units and around 700 data loggers, primarily from SOFREL, to monitor stations, collect data, and manage the operation of technical facilities. Wastewater lifting stations in particular are equipped with SOFREL S4W devices. These units control the full operation of the stations and their pumps. The S4 automation system is used to optimize flow management and prevent overflows. In addition to automation, the system allows for the collection of operational data, including volumes, pump running times, and any detected faults.
As an OIV operator (Operator of Vital Importance), data and access security are top priorities for Eaux de Vienne. The deployment of SOFREL S4W and its ecosystem enhances cybersecurity measures. They ensure secure connections through agent-specific logins and passwords. Data is encrypted, and communication between equipment and the supervisory system takes place via a dedicated VPN and regularly renewed security keys.
Water distribution sectorization and ongoing leak detection across the networks
A sectorization strategy for the distribution networks has been implemented to improve leak detection and minimize water losses. Each sector is subdivided according to the distribution layout. At each water tower outlet, sectorization meters and SOFREL DL4W data loggers have been installed to collect data, calculate average, peak, and nighttime flow rates, and carry out water balance reports.
The transmission of recorded data at the beginning and end of each sector allows for in-depth data analysis. The 700 data loggers deployed across the distribution networks provide essential daily information for detecting leaks and optimizing performance.
Eaux de Vienne is committed to responding quickly to pipe bursts and manages around 1,500 incidents per year across its 10,000 kilometers of network.
Thanks to this strategy and its commitment to leak detection, combined with the innovative and user-friendly nature of SOFREL solutions, Eaux de Vienne achieved a performance rate of 82% in 2022. However, the Syndicate is not fully satisfied with this result and aims to go even further in the future.
