Berliner Wasserbetriebe Gets RFID Tagging Project Flowing
The German utility, which provides drinking water and sewage services, expects the effort to simplify the inventory process for some 62,000 pieces of equipment at 17,000 locations.
Mar 02, 2007—Berliner Wasserbetriebe, the utility company that provides the city of Berlin and its surrounding areas drinking water and sewage services, is tagging 62,000 pieces of machinery, equipment and other valuables with RFID tags. Later this year, the company plans to begin using the tags to speed up and simplify its yearly inventory of capital goods.
Angelika Neumann, head of the firm's inventory process, dreamed up the RFID application to make her job easier. Her team and the company's subsidiary, Berlinwasser Services, developed a detailed plan for the RFID project, then presented it to the four-person management board, gaining its approval. The company has since attached RFID tags to 12,000 of the 17,000 specific locations at which tagged machinery and other assets will be inventoried. These location tags are attached to such items as doorframes and control boxes in the facilities where items are stored. The tagging of individual pieces of equipment and assets will begin later this year. In total, Berliner Wasserbetriebe will use almost 80,000 Smart-tec 13.56 MHz passive tags that comply with the ISO 15693 standard.
Berliner Wasserbetriebe serves 3.8 million people, has around 5,000 employees and reported sales of about 1.12 billion euros ($1.48 billion) in 2006. The company operates nine treatment plants, a 7,857-kilometer network of fresh-water canals, a 9,360-kilometer network of sewage canals and 2,300 water-testing sites. Each year, Berliner Wasserbetriebe must account for its capital goods so it can write off the depreciation for each piece of equipment. It takes a team of about 140 people the entire year to manage the inventory and perform such related tasks, including controlling, purchasing and bookkeeping. The company considered tagging items with bar codes but decided against it, since much of the machinery is outdoors and exposed to dirt and mud, which can negatively impact the ability to read bar codes.
Neumann analyzed the inventory process to locate its weak points—that is, those steps in which errors were frequently made or that needed a particularly long time to complete. In the soon-to-be retired process, workers take lists generated by an SAP R/3 system and inventory each piece of equipment by hand. They then create other forms that document which items need to be transferred to different departments or replaced. Results of the inventory are submitted to a manager, who approves them with a signature. Eventually, the information is entered back into the SAP system. The entire procedure's potential for manual errors is high. "This does not lead to an optimal process," Neumann says.
The new system aims to shorten and simplify the inventory process, while providing Berliner Wasserbetriebe a better overview of the condition and location of its capital goods. The list of items to be inventoried will be transferred from SAP R/3 to a database workers will use to conduct inventory. With a faster inventory process, items can be put to use in other divisions more quickly, and the overall facilities management process can be performed more efficiently.
