Zillia mineral water is well protected from severe drought in Corsica

while the lack of Water On the surface, the subterranean resource appears to be insensitive to climate changes. In factory ziliaa we will It recovers 30-year-old water from a depth of 80 meters, its properties are analyzed daily.

During this summer period, the Zilia plant runs at full speed, both during the day and more often at night.

July and August each represent five to six times the amount of water sold during the winter month.director Francoise Ciavadini notes, while the good numbers for July have just slipped. I can’t tell you how many liters we sell every day, it’s just huge. We’ve never sold as much water as this year. We are working as hard as we can and all teams are mobilized, respecting the annual quotas set by the ARS of course. »

The relationship between temperature rise and water demand is self-evident to the manager, especially since the summer period corresponds to the period of tourism on the island. But other, more subtle factors must be taken into account. “You must also understand that the increase in our sales is due to the difficulties in transporting water from the continent.Françoise Ciavadini book. In the summer, priority is given to passenger transport. The more cars in the boats, the fewer trucks there are. Since water is a low value-added product, agri-food professionals prefer to fill their trucks with high-value-added products such as oil, sugar and coffee. »

About 95% of Sodez’s production, the Zilia water company, is destined for the Corsica market.

The six-and-a-half liter bottles, which is the company’s flagship product, alone represent more than ten million bottles sold, or 15 million liters. A quantity to which sales are added in all other forms 33 cl, 50 cl and 1 liter, glass and plastic, soft and flat, flavored, and even in bottles of about twenty liters.

Very stable resource

As the rivers dry up on the surface, the springs dry up, the waters run dry in the villages, and the subterranean resource seems undisturbed.

“This water that we get from 80 meters underground does not come from last year’s rain or snow.says Françoise Ciavadini. It takes more than thirty years to get to where we derive it from; This ensures a certain independence from the current drought. The flow is the same throughout the year, as are the temperature and chemical properties. Thanks to this almost complete stability, our water was classified as mineral in 2015. This water is the heart of our business, and we do our best to preserve it. This subterranean torrent that flows under the Zelia is not found everywhere. There were five years of preliminary hydrogeological studies before a decision was made to locate the plant here. »

Zilea factory has its own laboratory. Water is monitored and analyzed to measure quantity, acidity, temperature, conductivity and other technical parameters. This data, which must be stable, is held over the long term and sent to the regional health agency, which monitors activity closely.

Governors decree determines the share of water that will be withdrawn each yearClaude Christelli, Sodez Quality Manager. This operating stake, set by ARS, changed in 2015 when we became mineral water. It is determined by hydrogeologists according to an estimate of the available resources. Complex calculations make it possible to set a limit beyond which the resource will not be replenished. For the first time, this year, we’re hitting those stakes. »

The water withdrawn from the former Zilea crept into the slopes of Montegrosso, at an altitude of about 1,000 meters above sea level.

It then slowly travels through the granite rock before it is pulled up, 30 to 50 years later. The absence of urban areas and farms, around the place of infiltration and upstream, also contributes to the quality and stability of the resource.

In Zilea, the difficulties do not come from raw materials. On the other hand, the supply of packaging cardboard, pallet wood, and glass, as well as energy costs, reduce margins and profitability.

Fortunately, there is still plastic for the water bottle.He concludes, not without bitterness, the patroness of water Zelia.
