Citerna SA

We are a family business founded in 1969. It originally had two employees. 40 years later, we have 8. Management was taken over in 1991 by Pascal Clemenzo.
Since 1969, we have been affiliated to the Valaisan union of tank auditors, the ReValCit, and actively participate in its operation.
 
Our company, thanks to its training, equipment and experience is able to offer and guarantee you services performed to the highest standards and in compliance with current legislation.
 
The services we offer can only be provided only by people whose training, equipment and experience guarantee compliance with the state of the art. 
We are committed to giving you sound, objective advice. This is to ensure that you are not held liable in the event of an accident, which could result in environmental pollution.

After an on-site meeting with you, we will draw up a free, no-obligation quotation which describes the necessary and compulsory work, as well as the cost of our intervention.

The main activities of our company consist of: 
- Installation of new tanks 
- Internal maintenance of tanks
- Visual inspection from the outside of tanks
- Decommissioning
- Installation of PVC double jacket for buried single-wall tanks (2014)
- Installation and maintenance of service stations
 
We also install and apply products, such as:
- Coatings
- Laminates
- Flexible PVC sheets
 
These products are used to make protective structures or retention basins watertight. We also install and test leak detection systems, more commonly known as "safety devices".These are necessary and mandatory for water protection on certain installations, and must be checked every one or two years.
In addition, we maintain a round-the-clock presence 24 hours a day so that we can intervene as quickly as possible in the event of an alarm from one of these devices signalling an anomaly. You can reach us at any time.
