Well alcohol does have a strong anti-bacterial effect,and adding water to wine was a way to create more drink as there was very little clean drinking water. During the fermentation process many microbes die, eventually the yeast too dies in the anaerobic environment. I think adding water to wine and letting the two mix for a while would kill a significant percentage of the microbes, perhaps enough to make a safer drink.
Also because everyone, including young children, drank wine all the time from the beginning of the day until night, dilution was important in order to prevent the people from getting to drunk by the end of the day. In effect, the reliance on wine for hydration meant dilution could kill two birds with one stone.
NPR has a very interesting and informative article where they interview Paul Lukacs and his new wine history book. He talks about the necessity of wine dilution according to his research. http://www.npr.org/2012/12/04/166186416/inventing-wine-the-history-of-a-very-vintage-beverage

No. I think it is because of the lack of grapes (hard labour to cultivate the small fields unlike today where machines come and do up acres.

They also believed that they were not worthy to drink straight wine- only Dionysus and other gods could do that. They believed that the only reason they had access to wine was because the gods sent it to them.

It was done because the very best wines came from Greece where dried grapes were used instead of the normal harvest. This produced a much sweeter wine that required dilution to make it drinkable. It was expensive and thus reserved for special occassions such as a wedding - like the one in Cana that Jesus attended.

Whist adding wine to water even in small quantities does help to purify it, I don't believe that this was a primary motivation. The water used would most probably have been finest spring water anyway or occasionally sea water. Wine with added water is more refreshing and it also doesn't give as much of a hangover. Roman sources are forever talking about good or bad for the stomach etc and thus this side of healthiness - avoiding hang overs and stomach acidity, can be considered a reason too.
A little sea water gives a more mineral expression and as many of the sites most favoured by the Romans (Falernum, Vesuvius, Messina, Mosel etc) produce mineral wines, we can possibly assume that the Romans added sea water to heighten this minerality.
The Greeks certainly sun dried grapes and concentrated musts which might have allowed them to get their wines up to around 16% - mix 50/50 and it's the strength of a Moselle. Mix in 4 parts water and it's still the strength of a light beer. The alcohol is absorbed more readily at this strength and with less ill effect.

I don't have a particular source for this, but I remember my high school Latin teacher telling us that Roman wine was more like a strong, thick concentrate much stronger than the wine we drink today, intended to be diluted before drinking. Think like those 100% berry juices you can buy at health food stores in the US, that are undrinkably tart without adding water.
Moreover, we spent an entire class period learning about the central social role of the person designated to choose the dilution strength at each dinner party, known as the arbiter bibendi, the "drinking master." Choosing the wrong mix (too much water -- wine sucks; too little water -- everyone gets too sloshed) could result in social consequences among the Roman elite, i.e. not being invited to more dinner parties. We read about one of these situations, but I can't remember who the author was. Might have been Horace, or probably someone more lowbrow.
As to why it was made so strong in the first place, I have no clue.

According to this well sourced article, wine was diluted to reduce its strength, in order to avoid over-inebriation. Those who did not drink it diluted were seen as barbaric, uncultured, or besotted.
There are claims on wikipedia and other online sources that the ancients drank diluted wine or small-beer to avoid water-borne illness, but I can't seem to find a scholarly confirmation of this. Indeed, many Islamic cultures certainly got along without wine or beer.
