Customer: Waternet, The Netherlands

Application: Online toxicity monitoring for drinking water intake protection

Challenge

For drinking water utilities, early detection of accidental pollution events is critical. Waternet uses online biomonitoring as an additional safeguard to continuously monitor the quality of surface water entering its drinking water production process. After more than ten years of continuous operation, it was time to replace the existing TOXcontrol system with the latest generation.

Solution

microLAN installed a new-generation TOXcontrol online Toxicity monitor at Waternet‘s intake monitoring station. The system continuously screens incoming water using bioluminescent bacteria, providing an early warning for unexpected toxic contamination events.

The latest TOXcontrol incorporates:

• Integrated bacterial cultivation
• Automated positive controls
• Improved reliability and validation
• Continuous 24/7 monitoring of raw water quality

Results

•  Successfully replaced a TOXcontrol system that had operated continuously for more than 10 years
•  Maintains uninterrupted protection of a critical drinking water intake
•  Demonstrates the long-term reliability and durability of biomonitoring technology
•  Provides continuous early warning for accidental pollution events
•  Supports safe drinking water production for Amsterdam and surrounding communities

Why This Project Matters

Unlike many monitoring projects focused on new installations, this project demonstrates something even more valuable: long-term operational performance.

The original TOXcontrol operated reliably for more than a decade under real-world conditions before being replaced by the latest generation system. Waternet‘s decision to continue with TOXcontrol highlights the proven value of online toxicity monitoring as part of a comprehensive drinking water protection strategy.
