Can anyone tell me about borehole water supply?

[oolaroola]

The house we are buying has its own borehole.
I don't know anything about this kind of supply.
Can anyone tell me about any potential problems that could occur or any maintenance issues/ costs?
Does the water need filtering?
Thanks for any help.

We used to in our last home.

We had a uv filtration system in a little pump room. Once a year we'd have the water tested and the filter system serviced.

We never had any major problems and the water was lovely.

DH just said that obviously this depends on the quality of your bore hole. A friend had one done and their borehole was rubbish so they have constant problems.

I had one in Suffolk. The water was a bit silty. There was a filter and a UV steriliser, but if you ran e.g. a bath and left it, there would be particles settling to the bottom, and the WC cistern was dirty inside. I hope you can find a better filter. It might be better to get extra filtration/purification for the drinking tap, there are cartridge tap filters available.

You need a local person to maintain the pump when necessary, or you will have no water when it goes wrong, or if there is a power cut. I had a loft tank so a buffer in reserve.

where I live now there is thick chalk and my local water co pumps it out, it is very pure, but hard.

Thank you both.
I will look in to filtration and testing.
I think it's currently tested twice a year, but not for bacteria.
I guess we should also ask about age and maintenance records.

If it has a UV lamp this will kill any bacteria (technically it just stops the bacteria growing but this is fine), a good filter will remove any solids.
A 0.2 micron filter is classed as a sterilising filter so no bugs etc can pass through it but the bugs in it can become a breeding ground for more bacteria, so just make sure you get good advice and fit the right filter size.
In my experience bore holes often give water fit for drinking but the bits and bobs are added for piece of mind.
This company have been around for years and install them all over Europe so must be good.

The water will taste much better as it has no chlorine in it.

Ours was technically fit for drinking from the borehole. Because we were also a commercial premesis we had to have the filtration system and water testing.

Ah thanks again that's very useful info.
