Clemessy sectors the SIVOM Val d'Allier drinking water network, a project funded by the Water Agency

The Val d’Allier inter-municipal syndicate SIVOM is in charge of the drinking water supply and wastewater management for 32 municipalities in the Allier department. The SIVOM has commissioned a consortium comprising GDCE (leader) and Clemessy (co-contractor) to modify the pipes in its network and to create and equip sectorization manholes. Clemessy is undertaking the network’s digital sectorization, in order to carry through this project financed by the Water Agency.

Sectorization involves dividing a drinking water network into homogeneous sections to equip it with meters and/or flowmeters. The study of these different sectors then enables a diagnosis of the state of the network to be made. 

Sectorization allows daily water volumes and time-stamped flows for the various sectors to be measured, recorded and transmitted to a central supervision station. This operation also makes it possible to detect areas with leaks and thus effectively contributes to improving network efficiency. In addition, meters for large consumers (industry and agriculture) have been installed to monitor their consumption, especially during low-water periods, and to set up common roadmaps for managing water consumption in the years to comeexplained Julien Delorme, business development manager for the Environment Division in the Centre-East region. 

Local sectorization stations equipped with 13 remote transmitters and 62 SOFREL data loggers are to meter water volumes transiting in well-identified sectors. They will communicate regularly with the central supervision station, so that the SIVOM operators can monitor the various changes in the volumes distributed, and particularly the night flows. 

By enabling remote management and supervision of the site, this sectorization of the drinking water supply network will help the SIVOM to combat losses and potential resource wastage, thanks to detailed analysis of its hydraulic data.
