What does drilling a Hole for Water cost here in Europe?
Lord of nothing:
Hi
Long story Short here in Vienna we have a Thermal Bath where the Hot Water was found by accident during an search for Natural Oil. Wikipedia say the drill 900m deep: https://de.wikipedia.org/wiki/Therme_Wien
So I life on the other side of my City and I asked my self what does such a drilling would cost?
If here in the same depth hot Water would be found it would mean "free" Heating for the next Century and free Water. :-DD
Does someone know it or maybe done if before?
Thanks

We produce a TON of electricity from geothermal sources:

I would think that drilling to these depths would be prohibitive for individuals. I have been told that the steam/water is quite corrosive and that creates another constraint.
Our water well is 300 feet deep and newer wells are drilling to 1000 feet. Right now, the water level is at 200 feet so we're ok, for a while. I don't look forward to drilling further.
Gas and oil wells can go to 30,000 feet - that's a hike!

Not only that, but if you're talking about individuals drilling the piece of land they own, that would just be illegal in many countries. Depending on local regulations, the "depth" of land you own is very variable, but often pretty limited.

Theoretical in my Country its not possible to "own" Something since the Gov. can take the Land who you life away and re purpose it. You also have to pay Tax just for "own" a Land who I would say it more pay Rent to the Gov. But beside of that dont be to political. Sure I know I must apply for an Permit but before I drive the Gov. Employee to insanity I would like know if it is affordable enough or so expensive to not think further.
Sorry I have no idea what something could cost. So before I plan way ahead in the Future its good to know if it is just a dream or it could come true.
Thanks :-+

I can't speak to costs in your area. Drilling costs always vary wildly with the material being drilled, the size of the hole and required liner. Obviously hard rock (taconite for example) is worse than sandstone and best case is loess soils found in some locations to the depths you mention.
Here in the US a ball park figure for a six inch (12 cm) borehole with a liner appropriate for domestic water would be $25/ft or about $75/meter. But that is a very large ball park. I would not be surprised at values 3-4 times larger or a factor of 2-3 smaller. Doing lining and or plumbing for a hydrothermal system would undoubtedly be higher, and I believe for this type of things costs in western Europe tend to be a bit higher.
