Any public wells / hand pumps in Dublin parks?

I'm not using any kits to make my cider. I select ingredients myself and try to buy the purest possible. From my experience, juices from the supermarket are terrible, full of chemicals and even if they work with yeast, they smell like sewage.

Usually I buy normal fruits and blend them. They have fewer chemicals in them (pesticides), give very good taste and ferment much better with yeast. The latter I get from foreign shops - fresh. Hungarian yeast is vey pure, Polish seems to be somewhat diluted and has a bad aftertaste. Then I use sugar and tap water with those ingredients.

Now, as kind of an experiment we are trying to make cider from proper organic ingredients. I already found sweet berries in a forest near Dublin. Then bought pure fruit sugar and found proper fresh yeast with no aftertaste.

The only thing I need now is water. Originally my intention was to collect some rain water and than filter it and boil it. However I would prefer a more normal solution like water from a well.

The idea behind all this is to see if real, organic home brew cider is better. Last time I checked, to do reverse osmosis you have to buy equipment for around 200€. It's like buying a cow just to get a glass of milk.

Maybe "chemicals" -- when referring to common supermarket juices -- isn't the right word. I used to have apple, pear, and peach trees back in the days. I can tell that normal juice doesn't ferment like that. You can tell by the odd smell that this is not natural. There are different types of juices in supermarkets of course, maybe some are good but I doubt it.

The yeast I use is made for baking. However you can't really feel that in your cider. They are fresh, and very pure. I tried once some granulated yeast from a brewing shop, and its quality wasn't as good. I buy Hungarian yeast, from a shop behind Cineworld next to Koreana. The easiest to buy, Polish yeast is weaker and I think it has some added ingredients for baking. The aftertaste is bad.

Spring wells? You mean like streams? No I wouldn't try that. What I mean by saying "public wells" is basically a deep hole in the ground with something on top, like hand pomp to get water out. Something like this:

The source of water is underground and sealed off. They are quite common in mainland Europe, many of them quite old. They still work well and people, like tourists for example use them and I never seen anybody get sick or anything. I even had one made in my back yard. Maybe if the pomp is not in use for a couple of years the first few liters would have some dirt in them. All you have to do in that situation is start pumping and everything clears out after a moment.

Anyway I've seen one from the bus while on my way to malahide. It's just on the side walk, I wonder if it works.
