Part of the largest WWTP expansion project in Poland
Siemens Water Technologies will provide the Czajka Wastewater Treatment Plant (WWTP) in Warsaw, Poland with visualization, control and monitoring systems, as well as electrical installations as part of the largest WWTP upgrade and expansion project in Poland.
Valued at almost $33 million, the design-build project will help the Czajka plant meet Polish and European Union directives. These rules will require WWTPs to treat 100% of effluent discharged into the Vistula River by the end of 2010.
Warsaw is one of the largest and most densely populated urban areas in Poland. The Czajka plant serves most of the city and surrounding area. Its expansion will increase daily plant capacity from 180,000 cu meters to 435,300 cu meters.
Siemens’ project scope will include design, documentation, installation, testing and commissioning. The PCS7 standard-based automation and monitoring SCADA system will secure optimal flow, full control and visualization for Czajka’s wastewater treatment process. Process visualization can provide real-time data measurement, equipment status, alarm notification and system failure alerts. Detailed analyses and reporting on plant and process performance can be easily prepared using data logged during daily plant operations.
The PCS7-based controllers’ network covers all process stages. The system design includes nine process stations, 60 to 70 controllers, two redundant servers, five operators’ workstations, more than 1,000 analog measurements and more than 2,000 drives. The Czajka plant will remain online during system installation, resulting in uninterrupted wastewater treatment.
