It's raining here in central France, and has been since yesterday afternoon. I'm not too sorry. Barcelona in the Catalan region of Spain is facing its worst drought for many years with water supplies at a fraction of the normal level.
Since mid-May ships from Société du Canal de Provence have been supplying Barcelona with drinking water along with the ships from the Marseilles water company to provide about 6 % of the daily water consumption of the Catalan capital. The contract was signed in April and deliveries are due to continue for six months.
This is of course a very expensive procedure. If water leaving Marseilles is about 1 euro per cubic metre, by the time it reaches Barcelona, its cost will have risen to 8 or 10 euros. Blue gold indeed.
