Siemens to Provide Automation for Poland’s Largest WWTP Upgrade and Expansion Project

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 WWTP upgrade and expansion project in Poland. 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 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 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. 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.

The Siemens Industry Sector (Erlangen, Germany) is the world's leading supplier of production, transportation and building systems. Integrated hardware and software technologies combined with comprehensive industry-specific solutions enable Siemens to enhance the productivity and efficiency of its customers in industry and infrastructure. The Sector comprises six Divisions: Building Technologies, Industry Automation, Industry Solutions, Mobility, Drive Technologies and Osram. In fiscal 2007 (ended September 30), Siemens Industry generated sales of approximately EUR40 billion (pro forma, unconsolidated) with around 209,000 employees worldwide.

With the business activities of Siemens VAI Metal Technologies, (Linz, Austria), Siemens Water Technologies (Warrendale, Pa., U.S.A.), and Industry Technologies, (Erlangen, Germany), the Siemens Industry Solutions Division (Erlangen, Germany) is one of the world's leading solution and service providers for industrial and infrastructure facilities. Using its own products, systems and process technologies, Industry Solutions develops and builds plants for end customers, commissions them and provides support during their entire life cycle.
