Abstract
This article underlines the importance and the interest of high quality geotechnical studies prior to drinkable water treatment station, the ground foundation nature, the special deep-grouted foundations choice, consisting in injected ballasted columns, the soundings, controls and tests realised on these foundations. We describe the recorded anomalies and pathologies, the arisen questions, investigation complementary tests, the projected reinforcement solutions and the planned mode of repair. The consequences due to these anomalies are approached as well as engineering works of drinkable water treatment station problematics.
