SCADA solutions for Super Rimiez water treatment plant

10 July 2012

Veolia has selected ARC Informatique PcVue SCADA software to monitor and control services and operations at its Super Rimiez water treatment plant near Nice in France. Key factors in its SCADA choice were performance, ease of use and lower total cost of ownership.

Constructed in 1972, the Veolia Super Rimiez water treatment plant is a cutting edge example of global water treatment technology and it has seen a number of adaptations, including a total overhaul in 1998 and a systems update in 2007. The Alpes Maritimes Secteur Nice facility covers 12 drinking water production sites with a total capacity of 460,000 m³ per day and a 3,400 km hydraulic network. Water is distributed via a 1,200 km hydraulic network fitted with multiple valves, pumps and regulating equipment.

The plant manages every stage of a complex process that takes water all the way from collection points to household taps. Apart from the collection and distribution of water, it is also responsible for treating and storing the water in reservoirs located at elevated locations. This includes managing processes at the site itself, as well as all of the remote command and control functions for pumping stations and secondary processing installations located up and downstream, including 20 treatment works and the 90 telemetry stations forming part of the overall system.

To ensure the effective monitoring and smooth operation of this complex infrastructure, Veolia uses the SCADA to gather data, store it in a central IT system and then process the data. PcVue directly processes the data and displays it as animations (called mimic panels) using symbols that can be instantiated (known as objects). The information gathered is converted into standard PcVue objects and then stored in databases for subsequent use in associated spread-sheet tools.

The software controls and monitors processes at secondary sites too. The remote control and monitoring service installed comprises 26 SCADA terminals, which acquire around 50,000 variables from some 400 industrial PLCs and remote terminals. To achieve this engineers configured 1,800 mimic panels and 600 objects. “In addition to ultra-high performance, a major benefit of the ARC Informatique PcVue solution is the user-friendly graphic interface, which enabled our team of development engineers to configure mimic panels and objects much more quickly than with a traditional SCADA solution. This helps to reduce costs and application roll-out times significantly”, explains Marc Pons, Veolia Water engineer and head of the control-command department at the Côte d’Azur operational centre.

With regard to the data transmission network, the TCP/IP communication protocol is used throughout the plant, and at the 26 SCADA terminals. The system is based on a virtual private network on ADSL lines and the GPRS network, with a satellite link for the main connections and RTC, GSM and SMS packet transmissions for time-stamped data stored by a secure archiving server. The network serves around 450 monitoring sites and is capable of issuing an average of 8,000 remote commands and acknowledging and supervising 7,000 alerts every month.
