# Structural works for the ARA Thurau west construction phase

The Abwasserverband Thurau is building a new wastewater treatment plant at Niederuzwil to replace facilities serving Wil, Jonschwil, Zuzwil and Uzwil. This tender covers structural building work for the west phase. Excavation, PFAS remediation and pile foundations are performed by the client before or alongside this package, so the building sequence must coordinate with those works. The official TED deadline is 29 January 2027 at 12:00 CET; award criteria are in tender documents.

# Automation and process control system for ARA Thurau

The Abwasserverband Thurau is building a new wastewater treatment plant at Niederuzwil to replace plants in Wil, Jonschwil, Zuzwil and Uzwil. Designed for 130,000 population equivalents, the plant must include a fourth treatment stage to remove micropollutants. Construction is staged so wastewater treatment can continue throughout. This contract supplies and commissions automation, process control, alarms, operating data collection and communications systems.
