Summary

The Caveau des Byards cooperative is located in the heart of France’s Jura region and includes 17 winemakers making 2 200 hl of wine from 42 hectares. The winemakers sought to optimize the management of their waste water using environmental-friendly techniques.

The system involves collecting water used to wash pesticide sprayers and passing it over a sealed 30m2 container filled with a mixture of mud and straw. The microorganisms of the ecological bed gradually absorb the waste water.

Results

The bio-purification system is operational since May 2012.

It is used by most of the winemakers belonging to the cooperative.

The method allows the farmers to treat a higher volume of waste water (around 14 cubic meters), which brings positive impacts for the environment.
