Ca' di Mezzo natural Oasis

The self-cleansing properties of rivers exploited in a project to protect the Lagoon

The Ca' di Mezzo Oasis acts as a natural purifier of polluted river water and is a valid alternative to costly and often less efficient artificial purification systems. Right by the Bacchiglione river, its 30 hectares of agricultural land, re-flooded to maximise the natural, self-depurative capacities of the river, constitutes one of the most innovative natural depuration projects of recent years in Veneto.

The watery expanse of Ca' di Mezzo lies not far from Chioggia, amid the amphibian lands of the Veneto Lagoon and the mouths of the great Alpine rivers. It is an oasis with remarkable landscape and natural features, where the environment and valuable strategies for the protection of ecosystems and territorial reclamation, have productively come together.
The Venetian Lagoon is an extremely fragile and complex ecosystem, threatened by phenomena such as subsidence (lowering of ground level) and the absorption of polluting agents of agricultural, industrial and urban origin into the afferent waterways. A gradual increase in initiatives to preserve it has been witnessed over the last 20 years. Of these, one of the most significant projects was carried out at the Ca' di Mezzo site, within a prior reclamation project, in the territory of Codevigo. Thanks to the collaboration between the Adige Euganeo Reclamation Consortium and the University of Padua, an experimental project was commenced, with very positive outcomes.
As from the year 2000, an area of over 30 hectares next to the Bacchiglione has been flooded, thus creating a lamination basin that assists in the natural phyto-depuration of the waters. In other words, it favours the natural purificatory breakdown of polluting agents, made possible by reinforcing the natural cycle of water. The wetland zone of Ca' di Mezzo is in fact capable of filtering and uplifting around 50 tons of nitrogen and 5 tons of phosphorous per year which derive from the 9,700 hectares of upland cultivation.
The area was created not only to improve the quality of surface waters, but also to recreate a natural environment that is an ideal habitat for a number of life forms. Thus, a rich zone of biodiversity was established, accessible both to the community and tourists, equipped with paths and a working observatory. The Oasis is an ideal place for excursions and for educational and leisure activities.
