Gas storagePWT (Process Water Treatment)

2020 - 2022

The Teréga storage centre based in Lussagnet (Landes) can be used to store large quantities of gas for our customers. The site comprises various installations allowing the gas to be directed and stored safely.

It features, in particular, a water treatment station which needs to be replaced with a new station that meets the storage centre’s needs.


  • Creation of a new water treatment station
  • Increase in waste water storage capacity (3 tanks of 500 m³ each and 2 backup tanks of 50 m³)
  • Demolition and remediation of the old station
