Cecchi Val delle Rose - Winery

French VF+ HF + FWS treatment plant for treating the wastewater produced by the winery

At the end of 2010, IRIDRA started the design of a constructed wetland project in Val delle Rose (Grosseto, Italy), in order to give the new wine-producing firm a depuration system. This system consists of what is called a “French scheme”, which is composed of a vertical subsurface flow systems for raw wastewater (VFRBF), followed by a “classical” horizontal subsurface flow (HF).  as second stage. This type of scheme has already been experienced before, successfully, on the wastewater of another winery of the same client (Casa Vitivinicola Cecchi & F.) and the monitoring of this plant has permitted the optimization of this design following both the treatment aspects than the requests of the owner to improve maintenance operations. The plant was realized from 2011 to 2012, and start-up happened in September 2012 during the the grape harvest period.  The treated water will be reused for irrigation after polishing in a FWS system with a final pond for storage.

  • Needs:

    In 2010, the construction of a new winery of Cecchi Group began in Val delle Rose near Grosseto (Italy); the client, that has  just a constructed wetland for the treatment of wastewater in his main winery, wanted to continue in this direction conserving a great attention to environmental issues and permitting the reuse of treated water for irrigation.

  • Solution:

    The system consist of what is called a “French scheme”, which is composed of a vertical subsurface flow systems for raw wastewater (VFRBF), followed by a “classical” horizontal subsurface flow as second stage; to storage water for irrigation reuse, a little FWS with a final pond was realized.

  • Benefits:

    The CW system, compared with other technical solutions, has almost the same intervention cost but maintenance costs significantly lower; the operation of the plant is followed by the same worker staff of the winery, without need of unskilled labour. Reuse in irrigation is another focus of the project, in a region of tuscany traditionally affected by water scarcity.
