Bore Hole

All our water comes from a bore hole which is a modern well; instead of needing to be wide enough to allow a man to get down and dig it it’s just four inches wide. This was an electric pump lowered to the bottom, in our case about 30 foot – for some scientific reason it is much easier to pump water up than put the pump at the top of the bore hole and suck it out. Our water is full of iron and manganese and there's always the danger that it might be contaminated with germs from surface water so our water treatment has to deal with all of these. The iron and manganese isn’t that bad but doesn’t taste too good and tends to be bright orange – lovely!

In the natural environment the oxygenation of water - running in a stream, and it’s exposure to sunlight, deals with much of the filtration problems which we are trying to deal with using artificial means. In order to deal with any germs the water is put through a fine filter in order to remove any particles which the germs might try and hide behind and then blasted with ultra violet with a type of fluorescent tube, which kills the germs.

The iron and manganese are put through a filter medium which traps them. In both of the above instances the filters get clogged up over time so they have automatic systems attached which shut them down and use either water or a saline mix to “back wash” them and vent the dirty water. This happens every third day at around 2am – not a good time to make a cuppa.

The system also has a pressure vessel which stores 200 litres of water and so the bore hole pump isn’t cutting in and out all the time. It also keeps the water pressure in the system fairly constant – between 2 and 4 bar.
