Well, I'm happy that I live in Los Castillos and at least for the past 5 years, we've not had issues with the water. And before that, I lived in Sosúa Abajo, and there was never an issue. My mother-in-law lives in Sosúa Abajo and she has water 24hrs 7days a week. At least the majority of the "locals" in these places are aware of the issue and have their cisterns that they fill up whenever the water is getting to them, and in general, the water comes at least once or twice a week. And yes there are parts of these areas where the water doesn't come to regularly, for example, the upper parts of Los Castillos. That's mostly because the water pressure is too low, and those of us who live closer to the main street get all the water first, and then those who live further up, get the "left-overs". But I also believe that it's kind of one of the things you DO check before you move to a place. The first question me and my wife ALWAYS ask, and not only the owner of the house but also the neighbors is "how's the water situation?". If there's an issue, well I wouldn't be moving there.
