An unprecedented partnership in France for an operation of this size, it is through a single-purpose semipublic company (SEMOP) that SIAAP and Veolia will manage the day-to-day operation of this wastewater treatment plant which is a crucial part of the Paris region’s wastewater treatment system today and for the years ahead.
A public sector reference for the wastewater industry in France and Europe, SIAAP selected Veolia, following a call for tenders, to assist it in realizing its avant-garde project for its wastewater treatment plant located in Valenton, Paris region (France).
From December 1, 2017, Veolia will be working alongside SIAAP to prepare for operational start-up on April 1, 2018. In order to guarantee service continuity, a detailed human and technical transition program will be implemented under the responsibility of the full-time Director of the SEMOP supported by Veolia’s HR and technical teams.
In this SEVESO Directive classified plant, industrial security and team safety management are the day-to-day number one priority. Innovation here will serve to improve sustainable development and to optimize operation by developing an efficient and responsible management approach.
The Valenton plant will produce as much sustainable energy as it consumes. With cutting-edge digital, smart and connected tools, it will also employ geolocation for 100% of its facilities, together with 3D digital modelling to assist with operation, maintenance and works scheduling, training and for use as an educational tool. The introduction of a hypervision system will provide SIAAP with real-time tracking of its KPIs.
In order to strengthen the public-sector management side, an updated and visionary governance system will be based on a Board of Directors chaired by SIAAP and on a decisive commitment to transparency shared by all each and every day.
“With SIAAP, we are going to invent the wastewater treatment service of the future: a service based on excellence, in the forefront of innovation, and delivering remarkable performance on the technical, economic and social levels, thereby emphasizing SIAAP’s leadership in the wastewater treatment business,” explains Frédéric Van Heems, CEO Water for Veolia in France.
