Speyer, 01 April 2025 – As part of the construction of a modern filtration hall at the largest enercity water treatment plant in Elze-Berkhof (municipality of Wedemark), which plays a central role in the region’s drinking water supply, SpiraTec AG delivered key components for the technical equipment. The new hall, which can treat up to 12 million cubic meters of drinking water annually, replaces nearly 100-year-old technology and represents a significant step toward a sustainable and future-proof water supply.
After just 35 months of construction, the new hall at the Elze-Berkhof water treatment plant, owned by Danpower Umwelt (a 100% subsidiary of enercity), has been completed. SpiraTec AG was responsible for the delivery and installation of EMSR cabinets (Measurement, Control, and Regulation Technology), which are essential for efficiently managing the processes in the filtration hall. Additionally, SpiraTec handled the connection of the actuators and sensors in the filtration hall, including the parameterization and commissioning of valves, inverters, pumps, and measuring transducers. The creation of an expandable process control system, based on the platforms atvise, Acron, and June 5, which allows for flexible control of drinking water treatment, represents an innovative solution for utilizing the facility.
In collaboration with subcontractors, SpiraTec also provided several safety-related systems. This included the installation of a modern fire alarm system, an uninterruptible power supply (UPS), as well as low-voltage and medium-voltage systems (NSHV and MS systems). The installation of safety lighting ensures security within the building.
The total area of the basins at the water treatment plant is 420 square meters. The filtration capacity of this area enables the treatment of up to 1,750 cubic meters of drinking water per hour. With the commissioning of the new system, the water treatment capacity at the site has increased by 40 percent.
Through these innovations, enercity has reached an important milestone for the water supply of future generations. The filtration hall at the water treatment plant, with its cutting-edge technology and comprehensive supply security, has become a central pillar of drinking water treatment in the region, ensuring a reliable supply for around 700,000 people.
Sustainability and Future-Proof Supply
The commissioning of the new filtration hall thus marks not only a technological advancement but also an important step toward sustainability. By deploying energy-efficient systems, such as the photovoltaic system on the hall’s roof, which provides part of the required electricity, the ecological footprint of drinking water treatment is significantly reduced. Additionally, the modern technology enables even more effective water treatment, which not only ensures the quality of drinking water but also promotes resource protection in times of climate change.
