Apparently there's been an order to gradually, temporarily close all but 85 of Rome's over 2000 famous free-flowing 'nasoni' drinking fountains due to drought. Along with addressing conservation concerns, this will also allow for repair of some aging, leaking plumbing. Closures are supposed to occur at the rate of 30 per day, and those fountains are expected to remain closed throughout the summer unless significant rainfall alleviates some of the problem.
Humanitarian groups - including the Red Cross - are protesting the move for the disadvantaged who rely on them for drinking water and personal hygiene, and I guess they help keep the sewers clean as well so if things become pretty odoriferous...
Anyway, as carrying a refillable bottle around for taking advantage of cold, clean, free water from the nasoni is often recommended in the Rome threads, it's a head's up that working fountains may be fewer and farther between over the coming weeks.
Here's a list of the fountains which are scheduled to remain open, and a related article in English:
