Visit of the interior of the historic Gallargues-le-Montueux water reservoir in May 2020 by the Suez Water Company. The day before the visit, the Suez employee began to drain the tank for inspection. As the environment was confined he was the only one able to go down, a little , to film. So the very first shot was taken by the > Suez employee. You have short clips of it in this video and a little more on this one: 1st video of the inside of the water tank .
The historic construction plans with transverse and longitudinal sections allow you to find your way, you can look at them towards the end. Finally, to leave a visual testimony around this reservoir, a pleasant inhabitant told me some anecdotes. You can see them after the visit with an overview of the water flows during the violent storm of September 14 .
