The Valais’ bisse irrigation channels are part of its cultural heritage. In recent decades, the bisses, which have footpaths running alongside them, have become an increasingly important tourism asset for the canton. Conscious of the importance of the bisses to agriculture, nature, the landscape and tourism, the public authorities and local consortage irrigation management communities have restored them and now keep them maintained and in good working order.

The aim of this bisse flow rate monitoring project is to use an innovative monitoring method to reduce manpower requirements and anticipate problems such as overflows and landslips. To this end, an automation solution is currently under consideration.

Introducing a continuous flow-rate monitoring system would considerably improve the detection of anomalies and warn operational staff of the need for immediate intervention or preventive action.
