Citerna SA

We are a family business founded in 1969. It originally had two employees. Forty years later, there are now eight of us. Pascal Clemenzo took over the management of the company in 1991.
Since 1969, we have been affiliated with the Valais Union of Tank Inspectors, ReValCit, and actively participate in its operations.

Thanks to our training, equipment, and experience, our company is able to offer and guarantee services that are performed in accordance with best practices and current legislation.
 
The services we offer can only be provided by people who, through their training, equipment, and experience, guarantee compliance with the state of the art.
We are committed to providing you with sound and objective advice. This is to ensure that you are not held liable in the event of an accident that could cause environmental pollution.

After an on-site meeting with you, we will provide a free, no-obligation quote detailing the necessary and mandatory work, as well as the cost of our services.

Our company's main activities consist of:
· Installation of new tanks
· Internal maintenance of tanks
· Visual inspection of the outside of tanks
· Decommissioning
· Installation of double PVC jackets for single-walled underground tanks (2014)
· Installation and maintenance of gas stations
 
We also install and apply products such as:
- Coatings
- Laminates
- Flexible PVC sheets
 
These products are used to waterproof protective structures and retention basins. They are certified and have proven their reliability over many years.
We also install and monitor leak detection systems, more commonly known as "safety devices."
 
These are necessary and mandatory for water protection on certain installations and must be inspected every year or every two years.
In addition, we provide 24-hour on-call service so that we can respond as quickly as possible in the event of an alarm from one of these devices signaling an anomaly. You can reach us at any time.
