When modernizing their sewage treatment plant Calvià 2000 wanted to ensure that their plant operates with the highest standards of quality and efficiency. Calvià needed to integrate all their facilities in a single SCADA control center through S7 protocol, OPC UA. They needed a modern, scalable solution with built-in reporting functionality to be more efficient and reduce energy consumption.  

Siemens  technologies that made it possible:

• TIA Portal: TIA Portal is the gateway to digital enterprise automation. By using TIA Portal, together with WinCC Unified, a 75% reduction in engineering time has been achieved. According to Magdalena Martínez Conti, plant operator at Calvià 2000, "total transparency of energy consumption in the water treatment processes" has been achieved.         
• WinCC Unified System: "By customizing the visualization of our facilities with WinCC Unified, we can see possible errors or consumption graphs, start-up or shutdowns in record time" emphasizes Josep Pallicer, maintenance manager at Calvià 2000. In addition, WinCC Unified provides the Mallorcan company with real-time information on the main energy consumption indicators of the facilities in order to make the best decisions and optimize processes.         
• SIMATIC S7-1500 R/H  redundant: The high-availability redundant CPUs of the S7-1500 R/H range minimize production downtime and avoid loss of process data. The engineering corresponds to that of a standard CPU. The TIA Portal and the redundant CPUs manage the synchronization of programs and data. No additional user workload is required. This is engineering efficiency.         
• AI Energy Meter 480 VAC ST: With AI Energy Meter 480VAC ST, Calvià 2000 can configure up to 200 different energy and electrical measurement values, and thus obtain full energy transparency of your process. You can also determine the energy consumption and power consumption based on the measured values provided by the AI Energy Meter. In addition, the company can use the measured data for reporting and to determine the carbon footprint.         
• Remote control of pumping stations with S7-1200: The water collection collectors are connected to the wastewater treatment plant and travel for miles and miles through a system of canals. Remote control systems based on TIA Portal and S7-1200 CPUs integrate all these remote units directly into the management and control system.

Calvià 2000 is the municipal company of the Majorcan town of Calvià and is in charge of the sewage network, the purification and regeneration of water and the collection of waste.  
Calvià was looking for a SCADA solution for its wastewater treatment plant control center. Sewage and purification installations in the municipality of Calvià. 329.65 km of sewage and rainwater networks, 72 pumping stations and 4 waste water treatment plants.
