Xylem Helps Optimize Urban Drainage Systems

The municipality of Herford, Germany, has collaborated with Xylem to enhance the operation of its combined sewer system, located at the meeting point of the Aa and Werre rivers. Faced with challenges in controlling sewer overflows during rainfall, the utility undertook a pilot study in 2021 to evaluate Xylem’s Real-Time Decision Support System (RT-DSS). The system optimizes the use of existing retention capacity by continuously analyzing sensor data and providing control recommendations, all without altering the physical infrastructure.

The implementation of the Xylem Vue platform has contributed to a reduction of approximately 15% in combined sewer overflows within the monitored drainage area. The scalable solution offers centralized monitoring and control, allowing operators to respond to changing conditions while maintaining manual oversight. Following positive outcomes, the utility is expanding the system to additional sewers, indicating a growing focus on managing stormwater more effectively.

“After initial skepticism, I am very pleased with both the results of this project and our collaboration with Xylem. The Xylem Vue platform is protecting our waterways from combined sewer overflows by optimizing the control and usage of available storage capacity,” said Horst-Peter Sarnizei, Head of Special Infrastructures Maintenance.
