2018-2023

The pipelines constructed in the 60s and 70s linking the shut-off stations in Roques and Goyrans present anomalies (insufficient depth, restrictions, elbows, flood risk area) that expose them to risks of external damage and do not allow smart pig inspection.

Goals

Modernisation of the Roques shut-off station to allow maintenance by swabbing
Movement of the Goyrans shut-off station outside the areas at risk of flooding from the Ariège.
Reconstruction of two pipelines under the Garonne and Ariège using the directional boring technique over a combined length of around 3.1 km with nominal diameters of 150 and 300 mm
