New Process Control System from Siemens for Berliner Wasserbetriebe in Germany

Siemens Water Technologies has received an order from the Berliner Wasserbetriebe worth around 5.8 million euros for the migration of the process control systems in five purification plants. The Water Technologies Division of the Siemens Industrial Solutions and Services Group (I&S) will be implementing the project which is scheduled for completion by August 2010 without any interruptions to operation of the purification plants.

Siemens Water Technologies (WT) has received an order worth around 5.8 million euros from the Berlin Wasserbetriebe for the migration of process control systems in five purification plants.

The Berliner Wasserbetriebe handles the supply and disposal of water for the city of Berlin and the surrounding area. It supplies 3.6 million inhabitants with water and removes the wastewater of 3.9 million people in the region. Over 220 million cubic meters of water are purified every year in five purification plants with the help of 147 pump stations and a network of wastewater channels with a total length of 9,400 kilometers. Teleperm M, the Siemens automation system which has been used up to now, was installed in the Berlin purification plants at the beginning of the 1980s. In all these years, it has worked well and been able to cope with all the developments implemented by the customer. The range of modules and the software supporting them, however, have now become outdated. In order for the Berliner Wasserbetriebe to meet future demands of the plant, they decided to upgrade their five purification plants with new technology. The automation system will be changed over to the Simatic PCS 7 system from Siemens. This means that a completely integrated structure based on the Siemens TIA concept (Totally Integrated Automation) will be created from the operator control and visualization level right down to the automation and field level. The new structure will provide the customer with a simple and reliable process management system as well as the necessary flexibility and the option of easy expandability thanks to the use of well matched components. Migration was chosen as opposed to installing a new system in order to retain the valuable technological contents of the software. The customer's top priority is to replace the existing equipment without any disruptions and without the processing rates of the purification plants being exceeded or impaired. The changeover of the approximately 100 PLCs will take place in two stages. First of all, the software will be replaced. Siemens Water Technologies was able to offer an almost completely automated procedure for this, avoiding any costs for re-commissioning and ensuring that the plant will work exactly as it did before the changeover. In the second stage, the hardware components will be replaced after a trial period of six weeks. Once migration has been completed, there will be an identical operator control and visualization system at all the purification plants.
