Siemens to Provide Automation for Polish Plant

Siemens Water Technologies will provide the Czajka Wastewater Treatment Plant in Warsaw, Poland with visualization, control, and monitoring systems, as well as electrical installations as part of the largest wastewater treatment plant upgrade and expansion project in the country, according to an Oct. 8 press release.

Valued at more than 24 million EUR, the design-build project will help the Czajka plant meet Polish and European Union directives. These rules will require plants to treat 100 percent 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 m3 to 435,300 m3.

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.

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.
