A water borehole taps into aquifers which are underground stores of water created by rainfall and evaporation in permeable geological matter.
Groundwater provides about one-third of public water supplies in England and Wales. In most areas three times as much water is collected as is abstracted ensuring a plentiful supply for borehole usage. In some cases, the borehole will access an artesian well ensuring an incredibly strong supply of water.
It is important to ensure that the aquifer or underground store of water does not become polluted during work. We work to the highest industry standards and use non-toxic materials. And this is how, following a successful survey, we do it.
1) We drill the borehole and line it with a well screen and casing.
2) An annulus is placed around the screen and then packed with a rounded inert silica gravel or sand to act as a filter.
3) A seal near the top of the borehole closes the drill hole to the pipe and this prevents surface water which may be polluted from entering the borehole.
4) A sealed chamber is then installed which houses the well head and surface valves.
5) A pump made of stainless steel is submerged into the hole.
6) The pump can be powered by electricity, solar or wind and creates pressure to bring the water to the surface under pressure.
