            Veolia Water (France)

            3S Control: Solution optimised and standardised by management of overpressure pumps

            Reference: Water



            Customer profile:

            • Veolia Water, the Water Division of Veolia Environment, is the leading operating company for water services in the world.
            • With the knowledge gained from years of experience, Veolia Water provides local authorities with a high level of professionalism and technological expertise to manage and develop residential drinking water and wastewater services.
            • Over five continents Veolia Water is currently providing public authorities with its expertise in environmental protection with almost 5,000 operating or construction contracts.
            • Veolia Water's primary responsibility is to produce drinking water and supply it to customers' homes with a high continuity of service at the lowest cost.

            Customer objective and constraints:

            • Guarantee water distribution with constant pressure whatever the flow required, is a contractual obligation. For Veolia Water, it is important to find a compromise between service quality and energy savings and avoiding as far as possible pressure surges on water distribution.
            • The water distribution network is expanding, so the question is to make the right economical choice between increasing the number of booster stations or extension of water towers.
            • To rationalise the cost of booster implementation, Veolia Water wishes to standardise the control panel boards with the aim of being able to manage sites of 2 to 4 pumps while emphasising performance, reliability, maintenance, as well as deployment and operation.



            Implementation methodology (main phases):

            1) Meeting with operators to define technical specifications and good practices to be complied with in the control of boosting stations
            2) Partnership between Veolia technical department and Schneider Electric (main supplier of electrical devices and PLCs in France) to define, carry out and test a solution based on our specifications
            3) Pilot phase on some boosting stations 
            4) Beginning of commercial deployment with a global purchase agreement between Schneider Electric and Veolia.
